That's right, your translation was spot on.

@Chris: Thanks, replied there.

comment Should we disable the root user?
@Chris: Thanks, didn't know that. However, my concern wasn't whether or not physical machine access would allow one to wreak havoc (it obviously does :) - the idea was that disabling root login this way might further delay recovery in a catastrophic situation, i.e. cause additional costs. Noted, though, I'm much less concerned now. :)

To get the link recognized properly, replace ( with %28 and ) with %29. Markdown is a bit iffy about parentheses.

comment How do I find out what version of Linux is running?
@gyaresu: Thanks! That's good, should help jldugger to know that it works on Debian as well :)

comment How do I find out what version of Linux is running?
@gyaresu: If the above wasn't the problem, can you please try to replace log_begin_msg in the Debian section with log_warning_msg and retry? Might have gotten the function name wrong. In any case, it should have returned "unknown" if that function wasn't htere, but still.

comment Is James stable for production use?
Seconded. Most MTAs are a pain anyway, there's no need to actually go looking for more of that.

comment Severe write performance problem
Of course, testing before production deployment is vital. I've honestly never lost data to XFS as such (i.e. not in situations where any other file system would have lost data as well) and am a bit miffed at all the scare stories. I use it because its behavior is very predictable over time (the slowdown on a near-full file system is tolerable) and it handles both sustained high-bandwidth I/O and small files (think courier-imap maildir) well. Of course, a UPS-less server is suicide, so that's a given.

comment File delete in windows server 2003 fails sometimes
Please note that it's a shot in the dark. VSS should not cause behavior such as you have encounter. However, there's a certain distance from "should not" to "does not" we like to call "implementation details"... :)

gyaresu, have you actually invoked the get_distribution_type function? I've edited the post to clarify (see at the bottom.)

comment Should we disable the root user?
Unfortunately I'm not familiar with the way Ubuntu handles root. But if you're able to do "sudo sulogin" and get a root shell without being prompted for a root password, then no, it's not a problem, since conceivably the same mechanism will apply at boot. You could try looking grepping for sulogin through the initscripts to check when and how it's invoked.

I'm sure jldugger wants to find out which distribution family the system is running. It's unlikely a script would be affected by the kernel version unless it depends on some /sys or /proc stuff - and even then it's usually easier to assume based on distribution than on kernel.

comment How can one reduce computer sound noise levels?
Thanks, didn't consider that (SSDs are still either horrendously expensive or horrendously crappy, so they're not on my radar :D). Updated the answer and credited accordingly.

comment How much is IP V6 addressing being used?
And, without end user pressure, given that NAT is still a very viable option deployed by most if not all users, and given the current economic situation which does not lend to investment, I sincerely doubt most carriers view IPv6 as more than a just-in-case experiment - exactly what it has been ever since 2460.

The reason being, you see, that an IT manager does not give a flying /sbin/fsck about IEFT, NANOG, RIPE, and any other task force acronym you might care about. An IT manager thinks about either the bottom line, her/his yearly bonus, or both. And currently IPv6 adoption will cost you money with no tangible benefit over the next couple of years, not to speak about this Christmas. That's an easy decision - "we'll cross that bridge when we get there", which in real world terms translates to "not unless the server room is on fire."

I'm sorry, but that is complete crap. In theory, you are right, we are all a big, happy, rational, forward-thinking family. In practice, no reponsible sysadmin will for the time being bother to spend company resources on IPv6 because of the chicken-and-egg problem - if you are able to justify the expense of being IPv6 ready to your accounting department knowing full well that your ISP does not support IPv6 and will not do so in the next couple of years at least, then you are nothing short of a magician. Or, to rephrase it, you must be on a really, really big budget. The rest of us, not.

The obvious reason - Microsoft's dominant market position. OS support means jack diddly squat if the OS only represents 1% or 5% or 10% of deployments. By properly integrating IPv6 support in Vista and slowly pushing it on the server side via WHS and Server 2008 they are actually creating an use case which will eventually force ISPs to support IPv6 too. I'm personally annoyed that it's Microsoft who is providing the turning point, but that's life.

Chris, what do you do when there's a fsck error during bootup on one of the critical file systems?

comment Which UNIX filesystem do you use and recommend for servers?
Additional note: I tested this multiple times under simulated workloads ranging from media file server (stable high-bandwidth transfers) to busy mailserver (lots and lots and lots of small files) by pushing the big red button. XFS and EXT3 lost about the same amount of data. EXT3 was mounted with noatime data=ordered, XFS with noatime,attr2,logbufs=8,logbsize=256k.
