Matt Gourley's TechBlog - March 27th, 2007

I know I've been slacking on writing my updates here, for which I apologise. Here's the latest:

1) UPSTREAM backups on IPO2 are now running through Hipersockets. The change from handshaked to fixed MTUs for TCP/IP (1500) is my guess as to why this is working.

2) Today, after a hiccup on the connection between linux7 and IPO1 (mis-configured client), I got the UPSTREAM backups on IPO1 running through Hipersockets.

3) sudo(1) is now setup in production. It was determined that the db2 user on linux5 did not require sudo, and we had difficulties getting the DB2 X applications to run through it anyway.

4) Plenty of updates and software installations in production, mostly of the IBM JRE.

5) Allen and I are working on a plan for a shared root filesystem for our Linux images. I'm less concerned right now with getting a production-ready architecture than I am with getting the proof of concept running. Gary has just given us a few Mod-3s for testing, and I'm hoping to have a few roadblocks crashed through by the end of next week.

On the plate:

- Security auditing.
- Documentation on sudo(1).
- Documentation on UPSTREAM backups.
- Log rotation
- Omegamon documentation

Done:

- Added two 3390-3s to VM7 and formatted them.
- Created the user LXTST00 in by editing USER DIRECT. Ran DISKMAP and DIRECTXA (EDIT to make sure there were no config problems; ran DIRECTXA to create.

For tomorrow:

- Get with Brian to figure out how to couple LXTST00 to the SYSTEM VSWITCH1.
- Create LNXMNT:LXTST00.PARMFILE.
- Modify linux00:/usr/local/sbin/clone.sh to clone to LXTST00's 150 disk.
- Clone LXTST00
- Boot LXTST00
