Package: dnsmasq
Version: 2.12-1
Severity: important

After upgrading, dnsmasq doesn't provide anymore the DHCP service. I
didn't modify my dnsmasq.conf, nor did any other changes. I connect via
my other computer's DHCP client and it just doesn't receive any DHCP
offer. I've tried modifying the dnsmasq.conf adding "interfaces=eth0",
but it doesn't work the same...

Cheers,

What version did you upgrade from?

What (if anything) if logged in /var/log/syslog

What DHCP client are you using?


Cheers.

Simon.

This is the syslog of the other computer:

And this is the one of the computer running dnsmasq:

Aug 13 13:38:05 desktop dnsmasq[3599]: started, version 2.12 cachesize 150
Aug 13 13:38:05 desktop dnsmasq[3599]: DHCP, IP range 10.0.0.5 -- 10.0.0.255, lease time 12h
Aug 13 13:38:05 desktop dnsmasq[3599]: read /etc/hosts - 9 addresses

What DHCP client are you using?

I have the line "iface eth0 inet dhcp" in my /etc/network/interfaces, so I guess I'm using dhclient (from package dhcp-client).

I also tried with the DCHP client "pump", but it didn't work. I guess with other clients won't work as well.

Please could you try downgrading back to 2.11-1 and see if it works
then? The changes 2.11->2.12 are trivial. So it's difficult to see what
might be the problem.

And this is the one of the computer running dnsmasq:

Aug 13 13:38:05 desktop dnsmasq[3599]: started, version 2.12 cachesize 150 Aug 13 13:38:05 desktop dnsmasq[3599]: DHCP, IP range 10.0.0.5 -- 10.0.0.255, lease time 12h
Aug 13 13:38:05 desktop dnsmasq[3599]: read /etc/hosts - 9 addresses

After you fail to get a lease, can you confirm that dnsmasq is still
running (use ps to check that the process is still there) Does the DNS
part of dnsmasq still work? The only explanation I can create at the
moment is that dnsmasq is crashing somehow.

What DHCP client are you using?

I have the line "iface eth0 inet dhcp" in my /etc/network/interfaces, so I guess I'm using dhclient (from package dhcp-client).

I also tried with the DCHP client "pump", but it didn't work. I guess with other clients won't work as well.

I guess the client is not the problem. Please could you try this (as root):

/etc/init.d/dnsmasq stop

/usr/sbin/dnsmasq -d -q

That will run dnsmasq in debug mode, in the foreground, with all logging
on. Now try to get a lease as see what happens.

Cheers,

Simon.

Err.. sorry, but I'm not that expert: how can I downgrade to 2.11-1?
