I was having trouble with a server running Debian 4.0 (etch). Using the standard sources in the /etc/apt/sources.list the supported PHP5 version was 5.2.0-8+etch13 which contained a very annoying bug for my application. A daily running script – let’s call it the Importer – regularly exited randomly with a “Fatal error: Out of memory (allocated [...]

On the command line if you close a console with a running job, you kill the job. This is different with the tool ‘screen’, where you can attach and detach from a ‘screen’ without terminating it.

Since I am doing more and more stuff on the commandline, I noticed that sometimes I just wait for some task to finish to do a next step in a sequence to accomplish a certain goal. What if a running task would take an estimated 3-8 hours and it is Friday afternoon? In this case [...]
On my network I have a Buffalo Terastation as network-share for backups. Today I figured out how to mount it on another Linux-box (Debian Etch) so I could do file operations directly on my backup. The following worked out for me: Created dir /mnt/terastation2 Added the following line to /etc/fstab //TERASTATION2/SHARE /mnt/terastation2 smbfs username=marco,password=,uid=marco,gid=businex,dmask=707,fmask606 And [...]

If you have some customer projects running on webservers (must be accessible to you via ssh) and you would like to regularly backup critical data like mySQL databases or filestructures this post might be useful for you.
