RE: Fedora Core Linux 3 -- Snort IDS

[Pradeep Aswani <pradeepg_aswani () yahoo com>]

Hi Patrick,

Thanks for your advice,
I did, but I get again an error:

*****************************************

[root@secure etc]# up2date yum
http://fedora.redhat.com/download/up2date-mirrors/fedora-core-3
http://fedora.redhat.com/download/up2date-mirrors/updates-released-fc3
There was some sort of I/O error: <urlopen error (-3,
'Temporary failure in name resolution')>

******************************************
We dont have DNS server in-house, but make use of the
ISPs DNS server, Is it something to do with 'named'
daemon?


Thanks,
Pradeep
