Why you shouldn’t be stupid

Filed under: Linux — Tags: , , — bcotton @ 4:00 pm

With today being a holiday, I figured it would be a good time to patch our Solaris servers. Like a good admin, I made sure it was announced ahead of time, but that didn’t stop a few users from complaining when their jobs failed. But this post isn’t about users, it’s about me. After the patch cluster finished installing, I rebooted our main file server. Everything seemed to come up okay, but when I tried to access the NFS-exported directories, I couldn’t.

I thought it was rather peculiar, but things happen sometimes. I noticed that there were several working directories, all the newer ones. Odd. Oh wait! When I was re-working our first array (I’ll write a post about that soon), I commented some directories out of /etc/dfs/dfstab. When I rebooted the server, it didn’t re-share those directories. A quick edit to dfstab, and a restart of the nfs.server process and we were back in business. Or are we?

Three directories still weren’t automounting. One was complaining about permissions, and two complained that there was no such file or directory. By this point, my colleague Randy had popped online and was helping me take a look at this. He noticed that the ownership and permission on the server side were wrong for one of the directories. A typo in an rsync command a few days ago probably caused that problem, but it was easy enough to fix. So now only two directories were being angry.

But wait, the Solaris desktop machines weren’t having any problems, it was just the Linux clients. Well that’s odd. So we tried clearing the nscd cache and restarting autofs. No changes. If the problem was the autofs configuration, everything should be broken, right? Randy found a note in the client’s syslog that it couldn’t find the server. DNS problem perhaps? The server has an entry in /etc/hosts, so it shouldn’t be an issue, but it wouldn’t hurt to look. I ran tcpdump on the client and not traffic passed to the nameservers while I was trying to automount the directory, so it couldn’t be DNS.

I tried manually mounting one of the directories on /mnt. It worked fine. Odd. I ran snort on on the server to look for traffic from the client I was testing on. There was absolutely no traffic when I was trying to automount. Well that would explain why it wouldn’t mount the directory, but why wasn’t the traffic getting through? Randy and I were beating our heads against the figurative wall, and the advertised outage window was minutes from closing. Then Randy sent me another snippet from the log file. I immediately saw the problem: the server name was mis-typed in the maps for the autofs configs. ‘server.empolyer.edu’ is not quite the same as ‘server.employer.edu’. A quick change of the config and everything was fixed.

An hour and a half of frustrating debugging because I mis-typed a few lines months ago. Oops.

Nugget Night update

Filed under: Funnel Fiasco — Tags: — bcotton @ 10:17 am

Well, we’ve reached #37 in a row (*snicker*). My friend Kevin was on hand, and felt the need to one-up my personal record by eating 72 nuggets (so I guess he two-upped me). More disconcerting is the fact that one employee, who weighs the same as I do, has eaten 110 nuggets in a sitting. The store record is apparently 120. So now I have a goal to work towards, and I’ve got a plan to get there. In the meantime, the CFA page has been updated.

Some FunnelFiasco updates

Filed under: Funnel Fiasco — Tags: , , — bcotton @ 4:18 pm

I know it doesn’t happen very often, but some FunnelFiasco updates got made today.  Most notably, I’ve updated the “About Ben” page.  I’ve also made a few minor changes here and there.  Over the coming months a few more changes will be made, mostly to streamline things.  As a matter of economics, I’ll be changing the hosting package I have.  The only real restriction is that I’ll have 10 subdomains instead of unlimited.  For the amount of content I have, that’s fine.  The wedding subdomain has been nixed, since it hasn’t been updated since I got married nearly a year and a half ago.  The kc9fyx subdomain will be nixed soon, once I make sure all of the links have been updated.  Not like htere’s any content there either. :-)

I’m also pondering moving the blog to a platform like Blogger, since I never seem to get around to performing the WordPress upgrades.  Or maybe I’ll just do the install and future upgrades through Fantastico.  The fact that there’s not currently a way to move non-Blogger sites into Blogger makes it rather difficult.  We shall see.

Could someone please turn up the heat?

Filed under: Weather — Tags: , , — bcotton @ 9:03 pm

So far, this winter has been pretty mild.  We’ve managed to avoid the ten-plus inches of snow that hit Chicago this weekend, and the temperatures have been nice overall.  There was the Sunday before Christmas which was miserably bitter, but a week later we were in the 60s with thunderstorms, so it’s hard to complain.  And then this week comes along… I just hope the City Bus can start in -10F.  Three nights this week have a low forecast below zero.  I’d understand this if I lived in Duluth or Missoula, but I don’t.  I live in central Indiana.

The Sunday before Christmas was the coldest day I can remember.  The wind chill never got above minus 20.  Fortuntely, I never had to go outside that day.  Maybe I should just take the whole week off.  The last time temperatures got this low, Martin University in Indianapolis suffered several million dollars worth of damage from a burst pipe, and Fark.com was chock-full of stories about people who burned down their houses by trying to melt frozen pipes with a blowtorch.  Please don’t do that.
