Yet another Day 10
It was a crazier day at The Office and I wasn't even at The Office; I was working at home.
And it's official—Ihate sendmail, dovecot and
saslauth.
I think the pinnacle of the mess was this lovely bit of
sendmail—from the configuration file
/etc/mail/access on the server as installed:
# Check the /usr/share/doc/sendmail/README.cf file for a description # of the format of this file. (search for access_db in that file) # The /usr/share/doc/sendmail/README.cf is part of the sendmail-doc # package. # # by default we allow relaying from localhost... localhost.localdomain RELAY localhost RELAY 127.0.0.1 RELAY
And the format of said file from
/usr/share/doc/sendmail/README.cf:
The table itself uses e-mail addresses, domain names, and network
numbers as keys. Note that IPv6 addresses must be prefaced with "IPv6:".
For example,
From:spammer@aol.com REJECT
From:cyberspammer.com REJECT
Connect:cyberspammer.com REJECT
Connect:TLD REJECT
Connect:192.168.212 REJECT
Connect:IPv6:2002:c0a8:02c7 RELAY
Connect:IPv6:2002:c0a8:51d2::23f4 REJECT
Notice anything … different … about the two?
Hmmmm?
Yeah.
XXX XXXXXX XXXXXXX piece of XXXX!
I think I got it working (the reason I think I have it
working is that I have no easy way of actually testing this crap!
All my email (both work and personal) is checked on the respective email
servers locally, using mutt since I find it faster that way. I
don't use POP or IMAP. While POP is pretty easy to test using
telnet, IMAP isn't. Toss in SMTP AUTH (which goes from difficult to
downright impossible to test via telnet) and I'm practically
forced to use some bloated piece of XXXX
like Lookout Outlook. Or Thunderbird, which
makes me pine for the days of checking my email as 1200 baud).
(Can you tell this stuff makes me rather cranky?)
My head es splode
One last bit of unfinished business from yesterday's switch installation—setting up Cacti to monitor the network usage.
But I should know better than to use a package manager to install required packages, but hey, I was a bit frazzled at this point.
I know that Cacti requires the use of RRDTool, and knowing that just
doing the straightforward yum install rrd would never work, I
did the next best thing:

What the—
Okay, try a more focused search:
[root@netmon ~]# yum search rrdtool Searching Packages: Setting up repositories Reading repository metadata in from local files No Matches found [root@netmon ~]#
Why did I even bother with the package manager?
So it's off to manually track down dependencies.
About an hour later, I finally get around to installing Cacti 0.8.6h (yes yes, I know they're up to 0.8.6i but I had the 0.8.6h tarball handy). It goes pretty smoothly, except that it's not generating any graphs. I run the cron job by hand, and yes, it's polling data from the network devices. Everything else is running smoothly.
Just no pretty pictures of network usage.
A few hours of pointless activity go by (I even inlist the help of Wlofie to see if I may have overlooked something) when I check the instance of Cacti we're running at The Office against the one I installed. We're running 0.8.6g. I happen to have the tarball of that handy.
I install that.
It works. I get pretty pictures.
A blood vessel in my brain explodes.
I'm found lying in a pool of my own blood, dead.
Oh wait! This isn't for NaNoWriMo …
