HI.. I had a similar problem where if I lost my link to the cable modem, I would restart /etc/init.d/networking and I wouldn't receive an IP from my ISP. I checked my syslogs like and sure enough, I my eth0 dhcp requesting a packet was being denied. So, I just stopped my firewall rules. then restarted /etc/init.d/networking and it was fine. I ran these: /etc/init.d/ipmasq stop /etc/init.d/networking restart /etc/init.d/ipmasq start
Thats what worked for me :) Mike Quoting Jaye Inabnit ke6sls <[EMAIL PROTECTED]>: > On Saturday 18 August 2001 05:05, James D Strandboge wrote: > > On Sat, Aug 18, 2001 at 11:51:19AM +0200 or thereabouts, john wa > wrote: > > > i have a dodgy cable modem which frequently cuts out requiring it to > > > re-negotiate the link. my firewall/irc box often fails to come back > after > > > some cut outs. > > > > > > > > > sometimes the interface remains up with the correct IP address but > for > > > some reason it can't find anything on the 'net. the dhcp lease has > been > > > the same for 2 months now so it's not the IP address given to the > modem > > > changing. > > > > Sounds to me like you are dropping the packets needed by dhcp.
