I recently found XMing, a free X server for Windows, providing a useful alternative to VNC for accessing remote Ubuntu desktops. Instructions here.

Thursday, May 1st, 2008Setting up SCP/SFTP chroot access to Ubuntu/x64 server
Monday, February 4th, 2008scponly provides a mechanism to enable secure file-access to a server, with marked improvement over FTP.
scponly can be setup in a) normal mode, whereby the user can see the whole of the file-system of the server, or b) in chroot’ed mode, whereby the user only sees the files the server administrator has granted access to. The latter is what I wanted, but there are a few extra steps required for 64-bit kernel servers. (more…)
Dell shipping PCs with Linux
Monday, October 8th, 2007I spotted on Ubuntu’s news-section that Dell finally have commenced shipping products (1 desktop, 1 notebook) with Ubuntu. Available in UK, Germany and France. Excellent!
Feisty (2.6.20-16-generic kernel) boot failure
Wednesday, May 30th, 2007In applying the latest Feisty Fawn updates to one of my laptops I ran into a problem with the bootup hanging shortly after starting. The usual snakeoil of ‘acpi=off pci=noacpi’ appended to the boot command line failed to make any difference.
Cluster monitoring and control
Thursday, May 10th, 2007I recently setup a cluster of Linux compute servers, and found myself looking for instrumentation to monitor & control the servers. The following open-source packages give excellent insight and access to the state of the cluster:
- Ganglia – server stats, historical data (check Wikipedia’s cluster)
- Monit – process monitoring/control
- MonALISA – dynamic distributed service architecture
Useful Linux sysadm articles
Wednesday, April 5th, 2006Linux-mag has a very useful set of ‘guru’ articles for newly-hatched sysadm’s.
Linux file-systems
Thursday, March 23rd, 2006I am happiest with the overall compromises and performance of XFS for my data, used in combination with ext3 on the /boot and root partitions. The XFS partitions hold either /var or /home (or both), depending on what purpose the system is put to. In my setups, /home is irrelevant for server-only systems, /var is where Postfix, MySQL etc will do I/O.
Email virtual domain hosting using Postfix, MySQL and PHP
Saturday, March 4th, 2006My present SMTP/IMAP setup uses a combination of flat-file configuration with MySQL user parameters. I recently found a web-based domain administration tool; Postfix.Admin. With this tool, you get 3 levels of management abstraction: server, domain and user.
