Kubuntu 8.04 and bash completion of known hosts

After installing Kubuntu 8.04 I faced with problem that bash completion of known hosts doesn’t work anymore. After a simple looking at content of known_hosts file I found that host name is hashing and not readable. It was done by security reason to prevent worms propagate themselves across networks.

To bring back bash completion and push system do not hashing host names just comment out the ‘HashKnownHosts’ line in /etc/ssh/ssh_config or by putting the line
HashKnownHosts no
into ~/.ssh/config.

Maybe it won’t be so secure but bash completion will work again.
