What date does it say when you run uname -a! FreeBSD TWEAK.HOME 3.1-STABLE FreeBSD 3.1-STABLE #3: Wed Jun 30 11:00:45 IST 199 9 root@TWEAK.HOME:/usr/src/sys/compile/TWEAK i386 FreeBSD MANSON.HOME 3.2-STABLE FreeBSD 3.2-STABLE #0: Thu Jun 24 20:54:25 IST 1999 root@MANSON.HOME:/usr/src/sys/compile/MANSON i386 I was unsure when i wrote that in the first place so I even checked. > You changed out the "hub" just because one FTP transfer didn't go as > fast as you would have liked?

Indeed it does, I noticed some slight network performance problems before, but nothing this severe, Also fariys only tend to visit me after too much Gin, which I havent indulged in for quiet some time.
