Re: [cobalt-security] Telnet timeout after login

[ChaosIndustries <chaosindustries@xxxxxx>]

Got my baby back ;)

For all of you, who dont have a chance to go on serial port, when
dns is down and telnet is timing out.

Ive checked out what happend and why dns was going down. 

Index.cgi in .cobalt/dns/ is renaming that file. Ive deleted the vhost 
first,
so klogd worked hard, for all users want to access that ip and the 
maschine
was going down - the index.cgi was killed while performance lost. 

Found that lines are part of index.cgi: 

unless ( ($Features{'bind8'} && (-e $Named_conf)) ) 
{ 
 $Named_conf = $Named_disabled; # Edit the disabled configuration instead 
 $Offline = 1; 
} 

Wrong time ? wrong line killed and you got a named.disabled and dns is 
down, and
unable to restart. You are cutted of without any chance for a telnet 
session.

Now i added a well known host and ip in hosts so i wont get a timeout
nextime when connecting from that ip to establish a telnet session to fix
the problem.

Maybe for someone of you that can be helpfull to prevent the same,
when you are not able to use a serial connection.

Regards Sven
