Re: [K12OSN] OT - Yum problem



 IMNaiveOpinion, it could well be that ssh, Network Manager or iptables
restarted on the update and you lost the connection. 

If you can physically access the box, grub should still have at least
the previous kernel as an option. 

If for some bizarre reason grub won't let you do that, you could also
boot the box from a removable device (Install/rescue CD, Knoppix, etc)
and edit grub (e.g. /boot/grub/grub.conf) if need be where it's easier
to see the parameters ie the older kernel version(s). Grub, of course,
can be temporarily edited at boot but you'd need to know which older
kernel to point it to 

(for example
root (hd0,1)
	kernel /vmlinuz-2.6.30.8-64.fc11.i686.PAE ro
root=UUID=1ef14036-12b5-42a0-971e-7e6cfb050f46 rhgb quiet
rootfstype=ext4
initrd /initrd-2.6.30.8-64.fc11.i686.PAE.img

which is one of my older entries in grub.conf) 

Good luck,
William
