At the PACC internship, at first, I started working on Italc software. I installed the program but faced some problems with authentication keys.

Then I changed the rights to the keys folder, so that a normal user (e.g. teacher) could launch Italc master's interface.

Italc, however, didn't work properly because, the client (ica) was also requesting root rights in order to be launched. If ica-launcher was implemented by a root, Italc would work well and the major Italc features would be working too.

(On my laptop, I installed and set up Italc too but did not have any difficulties with Italc, ica, avahi or anything else)

The next day I found out that the problem of ica-launcher lies in avahi implementation. Avahi uses .local hostname which is already used by local network (or at least, it says to be so). Changing avahi hostname did not work.

Later, prof. Norbisrath found that problems occur because the client asks for some graphical data which it is not allowed to have access to.
