Unknown Files in /tmp
by Mark Sargent 01 Feb '06

01 Feb '06

Hi All, 2 days ago, I used skype on my laptop, which hadn't seen the net before then. I successfully spoke with my mother, and had no problems. Yesterday, I had what I believe was an unauthorized access to my laptop, so, I changed all passwds on my smoothwall box, and also put the local host onto a new subnet. Today, I experienced some weirdness with skype, where, I could hear/be heard, but, the ring tone for calling/receiving had stopped. I most certainly made no changes to skype's configuration. Today, whilst snooping around my laptop, for numerous things, I came upon some files in /tmp, which I don't recognize, [root@localhost tmp]# ls keyring-XphDRC gconfd-racket mapping-racket ssh-qONcvE2869 gconfd-root orbit-racket xses-racket.bWVjc5 keyring-P5i6Xo orbit-root below is just some content from "xses-racket.bWVjc5" (nautilus:2955): Eel-WARNING **: Error starting command ''/tmp/keyring-XphDRC/socket'': Failed to execute child process "/tmp/keyring-XphDRC/socket" (Permission denied) I ran a soundcard test today, could that be it? This is all probably not related, but, I find it odd. What do you think? I googled for info on the filenames, but, found nothing. Cheers. Mark Sargent.
