Personal Information and Apple

If you did a clean install of MacOS X 10.4, part of out of box experience is filling out a bunch of things about what your name and address is, where you work, what your e-mail is, etc.

CMD-Q bypasses that screen, and continues as normal without asking for irrelevant information.

Thanks to Jon Rentzsch for the hint.

Spamcop lists gmail SMTP servers as spam servers

A while ago I ranted about automated spam filtering.

Here is yet another example of utter idiocy of some people.

Spamcop report for, aka currently states: listed in (

If there are no reports of ongoing objectionable email from this system it will be delisted automatically in approximately 2 hours.

Same thing for,,,,,, (all resolve to, and all are addresses in used to send email as listed by Ironport). I am sure rest of gmail is also reported as source of spam by SpamCop, I just can’t be arsed to keep on checking.

*sigh* Anyone needs any more convinient arguments for not using SpamCop? I am really really tempted to write a log parser that would automatically submit IP addresses of folks who use SpamCop back to SpamCop.

Oh, and at this point, when I talk about “utter idiocy of some people”, I am not even sure who I am refering to – SpamCop folks for listening to anyone reporting gmail (or hotmail, or yahoo mail, or any other “free” mail server) as source of spam instead of just whitelisting them, idiots who get a spam through a free gmail account, and report it to SpamCop as spam, or idiots who configure spamcop checks as default reject reason in their MTA.


Just in case I need to analyze kernel crash dumps under Solaris SPARC ever again, this is CTEact, the infamous act tool.

Dave doesn’t let me upload anything but the pictures and movies (heh!), so this will have to be renamed apropriately.
CTEact 7.17 SPARC, covers Solaris 2.5 through to 8
CTEact 8.2 SPARC, covers Solaris 2.8 through to 10.

Care and feeding of a Sun Ultra 5/10


I gave away another Sun Ultra 10 today.

As I invariably get questions about Solaris, Sun systems in general, etc, I figure I’ll document some things about caring and feeding for a Sun system.

My experience with Sun systems is somewhat dated – I’ve started with Sun 3 (3/260), and progressed through Sun4, sun4c, sun4m, sun4d (SS1000), onwards to sun4u architecture. However “biggest” sun4u box I’ve played with would be an Enterprise 6500, and biggest I own is an E4K. Thus asking me about domains on an E10K or bigger/newer would not get one far. As I’ve been out of of the workforce and in school for the last 3 years, my knowledge of Solaris 8 is very solid, and I can get by in Solaris 9, but know next to nothing about Solaris 10 changes – Containers, iSCSI, NFSv4, clusters, and other shiny new things that Sun introduced.

But basics are basics, and most of this is either OS independent, or can be transfered over to current versions of Solaris.

So keeping Ultra 5/10 in mind….

Ultra 5/10 hardware

Why am I calling it a 5/10? Because Ultra 5 and Ultra 10 share the same motherboard. Ultra 5 was coming in a pizza case, while Ultra 10 is a mini tower.

Modern Sun systems are very similar to PCs. Ultra 5/10 was one of the first mainstream Sun systems to support IDE (there were others at around the same time – SPARCengine2 comes to mind for some reason). So talking about IDE….

Both Ultra 5 and 10 were designed to operate with a smart card reader. Personally I’ve never seen one with a card reader installed (Maybe University of Ottawa has some), so all U5s and U10s I’ve encountered have a small “trap-door” in the front, with nothing behind it. On a U5 (which is small, crampled, and not very upgradable), you can install a second internal IDE hard drive in the space designed for the smart card. I had to do that once for an outfit called ResponseLogic around 2000, and from what I remember, it was doable, however you might need longer IDE cables to replace the ones system ships with (or maybe ones that have 3 IDE headers, instead of just 2), and only two screwholes would match the hard drive. Solution to that is either a dremel tool and drill to make the necessary holes, or just general contentment with being able to install a second hard drive. 🙂 Inside U10 there is space to mount additional hard drive, so space is less of a concern.

IDE bus on a U5/10 is seriously broken from performance point of view. I remember benchmarking an Ultra 2 with a 300 MHz UltraSPARC II CPU, and U10 with 440Mhz UltraSPARC IIi (?) CPU and a Symbios UW SCSI controller, both driving a multipack of 36 gig SCSI drives in software RAID under Solaris 8. Both had half a gig of RAM. U2 would generally perform ~10% better in IO operations, because U10 was booting from IDE, and IDE interrupts were killing the system performance.

With that in mind, if you have a SCSI drive and a PCI SCSI controller with FCode (that U10 can boot off of), it would make sense to convert the system to a whole SCSI system. Follow this link for good instructions. Plextor SCSI CD-Rom drives and burners are cheap used, and make really good CD-Rom drives in Sun systems in general.

IDE bus in U5/10 doesn’t support addresses wider then 40 bit. In practice that means that IDE hard drives larger then about 128 gig would not be recognized as such. I’ve never tried to put such a large hard drive into a U10, but I’d speculate that one can’t access the space beyond the 40 bit boundry, but otherwise drive works.

Sun systems are using OpenBoot (or Open Firmware) firmware for BIOS.

Primary language of OpenFirmware is Forth, which is of the same family as Common Lisp, Scheme, etc.
Some people are obsessed with Forth, and write crypto or play Tower of Hanoi using it.

OpenBoot used to be on track to become IEEE 1275 standard, but AFAIK standard wasn’t re-affirmed by the Open Firmware Working Group (politics, I guess), lapsed, and now a days Sun, Apple, IBM and whoever are just doing their own thing. Wikipedia has more, so I’ll just throw a bunch of links at the curious:

OpenFirmware Working Group site
OpenFirmware Working Group site (mirror, sometimes more up to date then the main site)
FirmWorks generic Open Firmware Quick Reference
Sun OpenBoot Collection – Contains reference books for OpenFirmware 2.x (Book P/N 806-2907) , 3.x (P/N 806-1377) and 4.x (P/N 816-1177) and Writing FCode (P/N 806-1379))
The following are Apple’s Technotes on Fundamentals of OpenFirmware (There are many Apple specific bits on OpenFirmware (such as setting up kernel debugging over ethernet) at the above link):

Eclectic List of OpenFirmware commands

After playing with OpenBoot on Sun workstations/servers, on modern PPC Apple systems, and NetApp filer (F760, at least, had firmware writting for NetApp by FirmWorks), I can say that Sun’s implementation is the nicest, not the least because it includes on line help.

Nothing substitutes reading docs above, and while OpenFirmware is the “same” each vendor defines their own commands, etc. Some commands that return pretty pictures on a Sun (banner for example) return nothing on a mac.

There are a bunch of hidden settings that can sometimes be found by typing words at OpenBoot Prompt. words just dumps all the known words – ie commands that were defined.

Here are a couple of suggestions for investigation at the OK prompt:
probe-ide and probe-scsi-all – Will list IDE and SCSI devices (will return nothing or an error if you don’t have IDE or SCSI, or the words are undefined
.speed – returns the speed of the processor(s). eg (on an a dual CPU 300Mhz Ultra II, {1} prompt refers to second CPU)

{1} ok .speed
CPU  Speed : 296.00 MHz
UPA  Speed : 098.66 MHz
SBus Speed : 025.00 MHz
{1} ok

test-all – test all hardware that has diagnostics. Might take a while. Can be used in conjunction with setenv diag-switch? true to troubleshoot hardware. Hardware or trouble might or might not shoot back.

show-devs to list avialble devices (another option might be cd / followed by ls to look at device tree natively. If you end up cd’ing to a device in a device tree, you can try .properties if it’s listed by ls, to see what words that particular device recognizes. *shrug*. Sun has an example of use

printenv to look at all the variable settings
setenv foo bar – to set environment variable foo to bar.
Most common settings that I use for debugging are:

setenv diag-switch? true
setenv auto-boot? false

This enables firmware diagnostics output on a Sun, and in conjunction with serial console logs lots and lots of interesting information about the state of hardware. Note that on big iron, such as E4K coming from cold to warm state, full diag might take
a good chunk of an hour (5×400 MHz CPUs, 6.5 gigs of RAM in my E4K takes ~15 minutes to test. This is when you start playing with setenv diag-level min (or max) to balance between more hardware tests taking longer, or minimal hardware tests taking less time). auto-boot? variable tells the system if it should try to boot OS right away, or drop to OpenFirmware after power-on, and wait for boot command.

Undoing the damage above is done thusly:

setenv diag-switch? false
setenv auto-boot? true

and you probably want to do the above before removing that serial cable from console, and rebooting the system unattended.

Note: boot command can take arguments that get passed to the kernel. Most common Solaris ones are:
-v Verbose boot – Kernel tells you what it does.
-r Reconfguration boot – Kernel instructs drivers to look for new devices added/removed since last boot and a bunch of scripts gets triggered on boot-up to re-populate the device tree. I’ll refere you to /etc/init.d/drvconfig and /etc/init.d/devalias on a Solaris system for more info. Oh, and drvconfig has a man page.
-s Boot into single user mode
-a Ask. When you really really screwed up your system by editing /etc/path_to_inst, /etc/system, etc, BUT made a backup before hand. If you are lucky, you might be able to get system back to bootable state at this point, and undo whatever you did. However, if you need to use -a option, you might be better off booting off CD into single user, mounting drive, and undoing the damage that way.

Folks are Princeton have some notes on troubleshooting Solaris boot sequence.

Oh, and from inside Solaris there is access to the nvram variables using eeprom utility (eeprom variable setting), and you can trigger reconfiguration boot by touch /reconfigure followed by init 6 or reboot

OpenBoot Firmware Updates

I guess I should mention that firmware on Sun systems is flashable.

If you have Solaris installed, you should consider updating the firmware to the latest version, by going to Sunsolve, and in patchfinder, finding the right patch for your system.

Patch generally includes file, that documents that installation procedure, and README file, that documents the list of bugs that got fixed by the patch. OBP patches generally require one to reboot, and boot from a particular file included in the patch.

Prior to doing this, one might be requires to open the system up, and move a jumper on the motherboard from write-protect into write-enable state.

Locations of the jumpers, etc can be looked up either in the print version of Sun Field Engineer Handbook, or at Sun Systems Handbook online

Here are some systems, and their corresponding patchIDs for OpenBoot updates (Search term is “Standalone Flash PROM Update”)

Ultra 1 (not Enterprise, 10bt) – patch# 104881
Ultra 1E (Enterprise, 100bt) – patch# 104288
Ultra 2 – patch# 104169
Ultra 5/Ultra 10 – patch# 106121
Ultra 60 / E220 – patch# 106455
Ultra 80 /E420R – patch # 109082
Ultra 450/E450 – patch # 106122
E250 – patch # 106503
E3x00, E4x00, E6x00 – patch# 103346

Breaking your Sun box, at OBP

And, to close off this section…. two quick “hacks”

Changing the MAC/hostid of your Sun box for fun and profit.
If for some reason you need to change the hostid or MAC of your Sun system, please refer to the great Sun NVRAM/hostid FAQ by Mark Henderson. I don’t want to fall into trap of discussing why you’d want to do it, but if your OBP has mkp command (ie AFAIK anything older then a SunBlade should work, and I’ve tested this on SS10, SS20, U1, U2, U10, U60, E4K myself)….

01 0 mkp
80 1 mkp  < = System type.  For sun4u arch 80.  For sun4m arch - 72.  Anything else - read the FAQ
08 2 mkp  <= Sun AUI is is always 08:00:20, which are the next three settings for MAC
0  3 mkp
20 4 mkp
c0 5 mkp <= c0:ff:ee to generate 08:00:20:c0:ff:ee as MAC
ff 6 mkp
ee 7 mkp
0 8 mkp
0 9 mkp
0 a mkp
0 b mkp
c0 c mkp
ff d mkp
ee e mkp
0 f 0 do i idprom@ xor loop f mkp  <= Calculates the checksum of what you did, and stores it

The above should generate a hostid of 80c0ffee and MAC of 08:00:20:c0:ff:ee.

Oh, and if you have a dead battery in your NVRAM chip, and system comes up with corrupt settings error on bootup, and refuses to boot, this will at least get it bootable.... until you yank the power and NVRAM loses settings again. It helped me a couple of times, while I were waiting for a new clockchip to arrive.

Note: for sum4m and sun4d arch, if the above doesn't work, there is a second way (c!) to do it, documented in FAQ.

Note to self: if playing with multi-board big iron, might need to follow up with copy-clock-tod-to-io-boards to synchronise NVRAM contents between the clock board (that you just edited) and I/O boards that still have old data. Reverse (if replaced the clock board, and are pushing settings from I/O board boardnum to clock, boardnum copy-io-board-tod-to-clock-tod. tod is, of course, Time Of Day 😛

Kind folks at PCI Alternatives mention that there is a way to overclock US-II chips at least from OBP. Their example is U5/10, and I've never done this myself, but....

also hidden nnn at-speed with nnn will change the clockspeed to nnn
.speed to verify, of course

Sun SPARCengine CP1500-440 Thermal Considerations (page 6) states that d# must be in front of the CPU speed, however as this is an undocumented setting, YMMV. Sun's documentation also has instructions on saving the command to nvram to be executed at each boot-up.

ok setenv auto-boot? false
ok reset
ok also hidden
ok d# 297 at-speed
ok .speed 

PCI Alternatives folks claim that 270Mhz U10 can be pushed to 297Mhz (+10%), and 333Mhz U10 can be pushed to 370Mhz (+11%).

Can 440Mhz be pushed up to 480? I’ll test it some time, and follow up, I guess.

“Safe” approach for something like this would be to run this without saving in NVRAM starting at +10% clock speed, and run SunVTS on a system to check if it’s stable. If it is, either increase the speed by another couple of ticks, and run SunVTS again, or just be happy, and save it in NVRAM.

Oh, and as a bonus to the patient reader….

Entering obdiag, extended diagnostic mode present in U5/10 and newer is performed by setting the following environment variables:

ok setenv diag-switch? true
diag-switch? =        true
ok setenv auto-boot? false
auto-boot? =          false
ok setenv mfg-mode on
mfg-mode =            on
ok reset-all

[system resets at this point]

ok obdiag

obdiag should return a bunch of loading messages followed by:

    OBDiag Menu

  0 ..... PCI/Cheerio
  1 ..... EBUS DMA/TCR Registers
  2 ..... Ethernet
  3 ..... Keyboard
  4 ..... Mouse
  5 ..... Floppy
  6 ..... Parallel Port
  7 ..... Serial Port A
  8 ..... Serial Port B
  9 ..... NVRAM
 10 ..... Audio
 11 ..... EIDE
 12 ..... Video
 13 ..... All Above
 14 ..... Quit
 15 ..... Display this Menu
 16 ..... Toggle script-debug
 17 ..... Enable External Loopback Tests
 18 ..... Disable External Loopback Tests

 Enter (0-13 tests, 14 -Quit, 15 -Menu) ===>

14 bails one out (setenv mfg-mode off might be a good idea at that point). 16 enables verbose mode. 13 tests everything.

For more information, refer to Sun Ultra 5 Service Manual (P/N 805-7763) Section 4: Troubleshooting procedures (Page 4-12 in rev 12 of the above manual, page 84 of the PDF)

Expantion options

I’ve had great luck with Symbios made PCI scsi controllers based around NCR chipset. In one case a PCI controller (not Sun branded and without OBP FCode in the PROM) was not recognized by the OBP in an Ultra 60, however was recognized by Solaris 8 once OS booted. Turned out that updating OBP to the latest version made OBP to recognize SCSI controller.

According to, the NCR53c875 chipsets are generally recognized by the OBP and NCR53c810 is recognized by the glm driver in Solaris. Their experience is with Compaq branded cards.

Now that Solaris source code is freely available, and driver developement kit is available, it should be reasonably simple to port any Intel drivers from Solaris Intel to Solaris SPARC. I toyed with this in Solaris 7 (when Sun first released a stripped down version of the source code to great unwashed under a general NDA), but it probably is even easier now.

Note that if the PCI card doesn’t have it’s own FCode in ROM, and is not amongst the devices supported by the OBP out of the box (built-in drivers), you won’t be able to use them before system boots and driver loads. This means no netbooting on cheap network controllers, or no booting from cheap SCSI controller. Or, I guess, no video on that Matrox or ATI video card before Solaris loads and X starts.

Installing Solaris

Oldest version of Solaris that would install on an Ultra 5/10 is 2.6 HW 3/98. Newest is what ever is current as of this writing. Personally, I’d recommend 8 for now, as it’s solid, still supported and well understood (at least by me), although that depends on the purpose – it one wants to learn the latest and greatest, of course Solaris 10 is the way to go. If one wants to be nostalgic, Solaris 2.6 was a very solid release.

Latest version of Solaris is downloadable from Sun. In addition, Solaris Express which is arguably more “bleeding-edge”, is also downloadable. Lastly there exists Solaris Express: Community Release. Confused yet? Solaris Express is the basis for Solaris 11, and Community Release is as bleeding edge as it gets. Older versions of Solaris used to be downloadable, but are no-longer. If you don’t have a friend with a CD (or CD image), your Solaris choices might be limited.

Depending on the version of Solaris you run, and the disk type you use, you might run into problems with the disk size and size of the root partition. Solaris 2.6 and 7 SPARC on IDE devices has some interesting features, that prevent it from booting or even accessing the disk. Certain versions of Solaris (2.6 SPARC on Tadpole SPARCbook comes to mind) had issues with IDE disks being larger then 8 gigs. Certain versionf of Solaris (7 SPARC comes to mind) had issues with root partition on IDE disk being set too large. Thus root partition on an IDE disk should probably be less then 2 gigs just to be on a safe side. Please refer to questions 5.63 and 5.64 of the Solaris FAQ for more information.

Normally with Solaris 8 I don’t bother with the graphical “Web Start” installation method. Booting from the 2nd CD (the ones that is labeled as 1 of 2, not WebStart) I would get dropped into the old style installation process.


The following is by no means exhaustive or “correct”, but will arguably cause you less grief then the auto-layout that Sun recommends.

Sun partitioning supports “slices”, which used to refer to partitions on SCSI drives. While SCSI drives support up to 8 partitions, IDE drives physically support only 4 partitions, so on IDE drives Solaris writes to a single physical partition, and then inside it creates 8 logical ones (even if you don’t use a slice, doesn’t mean it’s not there). But this is all boring hardware stuff that OS abstracts away any way, and chances are that the only time you’ll encounter this is if you are trying to multi-boot a Sun box between Solaris and Linux, or install Solaris on an x86 box. But this is not a paragraph about multi-booting, but a paragraph about partitioning, so….

The following partitioning works for me (format output of a 9 gig SCA drive)

partition> p
Current partition table (original):
Total disk cylinders available: 4924 + 2 (reserved cylinders)

Part      Tag    Flag     Cylinders        Size            Blocks
  0       root    wm       0 -  584        1.00GB    (585/0/0)   2100735
  1       swap    wu     585 - 1169        1.00GB    (585/0/0)   2100735
  2     backup    wm       0 - 4923        8.43GB    (4924/0/0) 17682084
  3 unassigned    wm    1170 - 1171        3.51MB    (2/0/0)        7182
  4        usr    wm    1172 - 1756        1.00GB    (585/0/0)   2100735
  5 unassigned    wm       0               0         (0/0/0)           0
  6 unassigned    wm       0               0         (0/0/0)           0
  7 unassigned    wm    1757 - 4923        5.42GB    (3167/0/0) 11372697


slice 0 – root partition. Mounts as /, and I usually go for between 1 and 2 gigs in size.
slice 1 – swap partition. Rule of thumb is 2x RAM in a system, although this is flexible, and if the system has gigs and gigs of RAM, maybe 1xRAM + 200 megs is good enough. Rationale is that in event that you end up with a kernel panic, or force a system dump at the OBP, swap is where the dump gets written to. swap is also used by the system as it boots up before it recovers the dump, and writes it to file. Yes, in theory there is compression of the dump as it’s written. But if your system died, and nothing is going right, do you think that compression will be effective?
slice 2 – whole disk. Used by things like fsck, format, mount, etc to address entire drive, and is never accessed directly by a user. Well, by a user that doesn’t know what he’s doing. Sun sets slice 2 up by default, so just leave it alone.
slice 3 – unmounted, unformatted partition of 5 – 10 megs in size, used to store the metadb replicas. What are metadb replicas, I hear you ask. metadb replicas are small databases of metadevice information, used by software raid, mirror, etc tools that used to be called Solstice DiskSuite and are part of the OS as of Solaris 8. Even if you think that you’ll not use disksuite, do create the slice, as it’s a small investment into disk space, and saves you lots and lots of hairpulling later. Each replica is ~2 megs in size, so 5 megs is a good number, as you’ll want a couple of databases per disk.
slice 4 – usr. Sun mounts if as /usr, and that’s fine. Under Solaris 2.6 – 8, one gig might be enough, but 2 gigs is probably better if you have the disk space, just to be on the safe side.
slice 5 and slice 6 – You can create a slice holding /var here. In fact, I do recommend either creating a /var slice, or running dumpadm, and changing the default savecore directory into which kernel crash dump gets placed from /var to /opt (or wherever you have lots of disk space).

root@llewella:/usr/exim[02:09pm]# dumpadm 
      Dump content: kernel pages
       Dump device: /dev/md/dsk/d20 (swap)
Savecore directory: /var/crash/llewella
  Savecore enabled: yes

dumpadm has a man page.

slice 7 – This is the rest of the disk that you still haven’t fully allocated. I mount it in /opt, symlink /home to /opt/home, and kill automounter (that tries to automount /home by default).

/opt is where things live in my world:

root@llewella:/opt[02:14pm]# ls
SUNWapcy         bind             gpg              ncftp
SUNWconn         db-      home             ncftp-3.1.3

audioctl-1.1     gnu              mp3

My world is not perfect, but it works 😛


For the longest time patching Suns was simple. Every once in a while (once a month was the norm where I worked), sysadmin would schedule downtime for reboot, etc, and a day or so before ftp over to, grab the jumbo patch cluster from there that corresponds to the release of the OS he runs, and uncompress it. If sysadmin is worth his salt, and has time, he’d read the READMEs for each patch, and check for incompatibilities. If sysadmin was optimistic, he’d just run install_patch, and hope that Sun QAed the jumbo cluster properly (hint: Sun doesn’t QA jumbo clusters, only individual patches, so there are times when one patch breaks the other. Bad sysadmin. Bad!). This all worked until Solaris 9. By Solaris 10, patch clusters are no-longer there:

So off one goes to, logs in, accepts a long license agreement, and selects patch finder.

There used to be a patchdiag tool to analyze the patches on a current system versus what is the latest and greatest. patchdiag required one to download the latest patch cross-reference database, patchdiag.xref from Sun each time you’d want to run it (required in a sense that you’d want to compare against the latest patches, right?). Latest database is at

Aternatives to patchdiag are Patch Check Advanced, vxpref, or patchfetch2 All use the patchdiag.xref file, some are pertier then others. I use patchdiag, but maybe I am a traditionalist.

Some of the patches patchdiag will report are “free”, while most are paid. So the solution is either to pay for a support contract, or sigh and be out of date.

So for Solaris 10 the way to stay up to date is to start by downloading the latest free jumbo cluster from patch finder, and using a paid SunUpdate service.

Sun Studio 11 (Compilers/Developer Suite) is now free

Alan Coopersmith (whom I’ve never met, yet whom I respect about as much as I respect Casper Dik) mentions that Sun Studio 11 is now free.

Download link is here.
Specifications – Basically Solaris 8 or newer on Solaris SPARC or x86. There is mention of Linux (RH 4 or Suse 9) on the sysreq page too, but I am kind of both disinterested by Leenuks, and somewhat puzzled, as RH 4 is circa 1997 and Sun folks probably mean Fedora 4. Or something.

Here Alan is doing some comparisons between Sun cc and gcc for compiling the X subsystem for Solaris.

I own single license for Sun Studio 6, which I picked up at a bancropcy auction (it was a box with never registered license codes) for 100 CAD. As part of a deal I got about half a cubic meter of Cisco propoganda for Cisco 25xx routers, but it was worth it.

Owing a license for a Sun’s C compiler for a while made me the coolest kid on the block, as I could compile 64 bit versions of IPF (gcc at the time stood in the corner and nerviously smoked whenever it had to compile 64 bit kernel modules)

My high end Apple service department….

I’ve mentioned cobbling together iBooks a few days ago.

Adam asked me to look at an out of warranty iBook that had a dysfunctional screen, and another one with dead logic board (magic smoke run out). I had an iBook without screen and without power distribution board.

After a long day I had 2 functional and one totally dead iBook.

One might ask what a high end iBook repair facility such as mine looks like.

Well, ask no longer.

Here you see my hightech repair facility (living room’s floor) with one functional iBook and 3 dysfunctional ones. Well, 2 dysfunctional and one mostly functional.

Mostly functional iBook in process of undergoing hardware tests.

Checking for mail and DNS problems

Dave’s recent arcicle about problems with reminded me that sometimes mail (and DNS) problems occure on the sending end, and some time on the receiving.

So I’ld like to take this opportunity to plug DNS Report, which is a really handy tool for rooting out problems with DNS and mail configs (or at least checking if DNS and mail are configured properly).

Here are a couple of examples:

DNS and mail config for
DNS and mail config for

I am not linking to my own domain, as it shows so much red, that I am embarrassed.

P.S. Dave, you might want to at least fix mail to postmaster. Thankfully stoopid folks from picked up their toys and left the sandbox. I hope so did the sheeple that used RBL.

Ok, rant time…

RBLs are a great idea in theory, folks. Sure, I know Dave, we have similar ideas about what e-mail is useless, so if he doesn’t like e-mail from Sonya Abacha, most likely I’d not want to read it either. However, what happened to every bloody RBL out there is that the moment it got sufficiently big, folks who created it (and they tend to be loudmouthed, obnoxious and highly opinionated folks, kind of like me) decide that they need to force their opinions on to others.

They tell the rest of the world that no, they are not forcing their opinion onto others, and that people are free not to use their RBL system. Vaild opinion. But how many e-mail systems come with RBLs enabled by default, and how many people heard that “Gee, RBLs are great, they stop spam cold!”, an d enabled it, only to start losing valid mail?

In particular I had an axe to grind with I had a /27 sub-allocated and routed to me from At one point Achilles had a problem with spam to postmaster (that by RFC must exist and must be read by humans), that Andrew Hutton started replying to all postmaster mails with auto-reply with a phone number and e-mail address that was read.

Some dumbass reported to rfcignorant because this was “against the internet rules”.

Another dumbass at RFCignorant promptly added entire Achilless netblock to their RBL.

And for the next 2 years chaos ensued – Andrew Hutton instead of giving out an e-mail addy that was actually read promptly started to /dev/null all spam coming to postmaster, generating illusion of postmaster being a valid e-mail address, I had problems with my own e-mail (that I hosted on DSL link from achilless, under a different domain name, and which was technically a totally separate organization just buying inet access from achilless) because entire Achilless IP space was blacklisted, attempts to get de-listed from the RBL proved to be futile, because dumbass at rfcignorant would add, but never remove entries, etc.

I learned about it when some of my e-mails replying to a mailing list question (“I am not subscribed, so please CC me on any replies”) got bounced with apropriate reply.

People that really got screwed on the deal were the rest of the interweb, I feel, as those who used rfcignorant RBL missed out on my insightful, witty e-mail commentary. Or something like that.

Oh well. That’s all water over the bridge now….

On the other hand, I have no moral qualms about bouncing all mail from Korea, or all mail from… Talk about double standards….
