lock file!
I found a lock file like this
lrwxrwxr-x 1 sskb apollo 16 Oct 22 22:00 lock -> hostname:2747
(pl. note that hostname is a number like 123.4.5.6)
but this was not shown in the file manager eventhough I had selected to show the hidden files.
I could not even read the contents.
can anybody give me info about this?
Thanks in advance
