Synchronise folders between Linux server and client

I sometimes find myself in a situation where I work on one project but use several different computer systems (all of which run Linux) for that. An example would be an exercise for university which I work on at home on my PC but then take my laptop to university to discuss it with colleagues. Always keeping all the files up to date on both systems is tedious and I often forget to do so. Hence my motivation for the challenge. I have a small server at home which runs 24/7 and is also accessible from outside via SSH.

Network tool for network administrators

My Matura project was to develop a network tool which provides certain services for an administrator. These services should help the network administrator to maintain the network. This includes starting of all pc’s in a network, watch their network traffic, status, shut them down and watch the content of their screen.

Displaying data from one Drupal site on another

The situation was the following: - Site A is used by companies to enter job descriptions. - Several Sites B want to access these job descriptions to offer a job board for applicants. Constraints: - solution has to be dynamic, e.g. a job entered on Site A has to be online on Site B instantly. - All sites are on the same server, so they can access the local MySQL database of Drupal.

Setting up a Linux Server to use LDAP for Samba, SSH

The main issue is that Samba and SSH do not use LDAP directly, instead you have to use the technologies NSS and PAM which will then access the LDAP system. So in order to set up two systems, about 5 systems have to be set up, which seems difficult and I was not able to find proper documentation about the whole process yet.

flow3, the new php based application framework of the typo3 team, was just released in version 1.0. is there any way to use the currently existing typo3 plugins built for the typo versions 4.x in an application based on flow or at least to port them in a way that they can be used within the new framework?

synchronizing multiple google calendars with nokia mobile

i need a pretty cheap - if possible free - solution to synchronize all my google calendars with my nokia c7. at least one of the calendars is not only used by me alone. it does not really matter if the solution also synchronizes tasks, but it would be nice.
