There's a couple of packages I maintain for Fedora, my distro of choice (most of the time). Most of those packages have to do with Yubikeys, a tiny, nifty device that generates one-time passwords. Check them out on Yubico's website.

I do a little programming in Python, Ruby, PHP, Bash and a (very) little C in my - almost nonexistent - spare time.

I currently work as a solution architect for Red Hat.

Have you tried with the full path to the hostname command?

@ThatGraemeGuy, that made me laugh :) I wish it always was that easy though.

comment How many rules can iptables support?
@kormoc: out of curiosity: what does that box do firewalling for? Firewall stuff is not my dayjob, but over 100000 rules sounds massive and I want to know :)

comment Java “Could not reserve enough space for object heap” but lots of RAM free
@DavidSchwartz, could be. I can run ''java -version'' on machines with a lot less memory than this though and Linux can overcommit memory pretty well with the default settings. I could be a non-default memory overcommit setting though, I can give you that ;) AFAIK, that could hinder virtual memory reservavtion.

I still think there is more going on. I have a weird feeling about this. (And you can accept my answer if it works for you ;))

It appears as a cronjob. Why is a cronjob listed in the strace output of ps?

comment CentOS iscsi initiator has session but there is no block device
I have seen this recently, too. Can you post the output of tgtadm --lld iscsi --op show --mode target and the part of /etc/tgt/targets.conf where you define your and targets LUN's?

comment What is vmlinuz and why do I care?
@MarkHenderson Check the access, modify and change dates with ''stat /vmlinuz''. You should probably be able to see updates in ''/var/log/dpkg.log''. However, if the machine is not configured for automatic updates, that should show very little.

comment How to cache authentication in Linux using PAM/Kerberos authentication (for CVS)?
@MateuszKwiatkowski, no it won't. nscd stands for 'Name Service Caching Daemon', it does not cache Kerberos passwords.

comment How do I determine the block size of an ext3 partition on Linux?
@dfrankow: if you have 8k memory pages, such as on Alpha hardware, yes. But you do not have those on x86 hardware and that is what I was talking about.

comment Shared memory: shmget fails: No space left on device — how to increase limits?
Wouldn't a limiting factor involving a signed int always mean that the amount of shared segments will be lower than 32768? Or am I misunderstanding you?

comment Shared memory: shmget fails: No space left on device — how to increase limits?
Setting SHMMAX to something huge is fairly common practice. Oracle, for example, recommends settings it to 4294967296 on 32-bit systems, iirc, which is a lot more than the 1677721600 above. It doesn't hurt to set SHMALL and SHMMAX to values that are higher than the available amount of memory. The value Oracle recommends for SHMALL is 1073741824, which, in pages of 4KiB, is the same as recommended for SHMMAX.

comment Is btrfs production ready?
Sure they have Chris Mason working there, but it is still a relatively untested filesystem on which I would not put any production data. I'd like to give it a spin and test it out a bit, but not without an open and working fsck tool.

For Postfix, that should be /etc/postfix/main.cf and not something like /etc/mail/sendmail.cf.

Well, how about that. I completely missed that :) Thanks for taking the time to read that manpage more thoroughly than I did ;)

comment RSyslog does not work with a log file located outside of /var/log
And then people never turn it on again, which is a shame, because SELinux is a great security feature...
