[Chilli] chilli malformed DNS

[Nestor A Diaz]

Hi, i am running coova chilli 1.2.9 under debian squeeze and 1.2.8 under 
debian lenny, the problem have been reported on the machine that runs 
debian lenny, i don't think this is related to the debian distribution, 
chilli hotspot keeps working, but it enter in an endless loop with a 
malformed DNS entry log, i have no way to check if it works fine but 
people who use the hotspot report the internet become slow.

I have another weird issue, after i installed chilli also the servers 
began to refuse connections to user root after a while, the only way is 
to restart the server, login as another user or restart the ssh daemon, 
i can't say this could be related with chilli but the problems began to 
appear when i installed chilli spot, i have google for a solution but it 
seems to be an old problem not present on modern distributions which is 
strange either.

auth.log.5.gz:Aug 29 08:59:32 panorama sshd[28150]: Accepted publickey 
for root from X.X.X.X port 33565 ssh2
auth.log.5.gz:Aug 29 08:59:32 panorama sshd[28150]:

auth.log.5.gz:Aug 29 08:59:36 panorama sshd[28150]:

chilli runs under chilli user.
