Hi guys, i am a intermediate user of ubuntu (but i am a ubuntu lover). I have a server which i use ISPconfig for virtual hosting, however, i would like to know about server administration.
what to look for? (logs files, users files)
what to delete? (cache, tmp)
Basically, i dont know anything on administration, so if somebody could help me on that would be great. Also note that i am talking about administration of the performance of the system.
Could somebody help me with that?
