KF performance problems continue.

Posted on November 1, 2012 by jaye

User reported KF was unusable between the hours of 11:00 – 1:15. Checked MRTG graphs, nothing at all. Poured through the config file. Increased the number of DB connections to 16. Also increased the logging detail to “debugging” level.

Kfserver now behaves when rebooted.

Posted on October 31, 2012 by jaye

Was able to test changes made Monday, to kfserver01. After editing the startup script to run as the correct user, KF now ignores stale lock files left from abnormal shutdown.

KnowledgeForum performance complaint…

Posted on October 31, 2012 by jaye

From customer Dylan:

Like yesterday, Knowledge Forum is really slow this morning, so much so that I can't really use it. Yesterday after school (around 3:00pm) it was back to normal, but this morning it is back to being slow.

Checked MRTG graphs, nothing unusual there. I suspect the backup may have been running at the time. Asked Erica to get more information from user.

More problems with Word

Posted on October 31, 2012 by jaye

Received a request from Kelly, regarding Karen’s problem with Word 2011

You can tell him that the message I have been getting when I go to save at the end of editing (after auto save) is:
file error, network connection or check disk for proper installation.Word work file 111153266

I am not saving to a disk. But I think the issue may be the prompt I get to save as 2008.

Responded with the usual “Update Word” is that doesn’t work, “Save as *.doc. then save back as *.docx.”

GMail as smartrelay on Ubuntu

Posted on October 30, 2012 by jaye

Setting up GMail as a relay in Postfix always seems to be an issue with me. Here’s a quick overview of the process:

  1. Install Postfix (if not already installed)
  2. Configure Postfix (if no main.cf exists). Use:
    sudo dpkg-reconfigure postfix
  3. Generate CSR, in /etc/postfix/certs
    /usr/lib/ssl/misc/CA.pl -newca
openssl genrsa -out itchy.key 1024
openssl req -new -key itchy.key -out itchy.csr
openssl ca -out itchy.pem -infiles itchy.csr
  4. Edit main.cf
    relayhost = [smtp.gmail.com]:587

#auth
smtp_sasl_auth_enable=yes
smtp_sasl_password_maps = hash:/etc/postfix/sasl_passwd

#tls
smtp_use_tls = yes
smtp_sasl_security_options = noanonymous
smtp_sasl_tls_security_options = noanonymous
smtp_tls_note_starttls_offer = yes
tls_random_source = dev:/dev/urandom
smtp_tls_scert_verifydepth = 5
smtp_tls_key_file=/etc/postfix/certs/itchy.key
smtp_tls_cert_file=/etc/postfix/certs/itchy.pem
smtpd_tls_ask_ccert = yes
smtpd_tls_req_ccert =no
smtp_tls_enforce_peername = no
  5. Create /etc/postfix/sasl_passwd file
    gmail-smtp.l.google.com user@gmail.com:password
smtp.gmail.com user@gmail.com:password
  6. Generate map
    postmap /etc/postfix/sasl_passwd
  7. Restart
    /etc/init.d/postfix reload

Nagios on Ubuntu

Posted on October 30, 2012 by jaye

Setting up Nagios for monitoring LiM access and other external services I discover the the Nagios3 package with Ubuntu sort of sucks. So much does not work, without screwing around. I finally bagged it and went with building the current release from SourceForge. The current release of the pluggins failed to compile so I went with the latest drop. That worked fine. Other than that, the build and install was simple, with no surprises.

The only remaining issue is that I still can’t get a remote SSH test to pass. More on that later.
