chainsaw: yours I think.
Who can reproduce problem on your local PC/server ? PS : generic option till now does't works. --------------------net.example------------------- # GENERIC DHCP OPTIONS # Set generic DHCP options like so #dhcp_eth0="release nodns nontp nonis nogateway nosendhost" # This tells the dhcp client to release it's lease when it stops, not to # overwrite dns, ntp and nis settings, not to set a default route and not to # send the current hostname to the dhcp server and when it starts. # You can use any combination of the above options - the default is not to # use any of them.
Look into /sbin/dhclient-script, the script is ugly and maybe that is the culprit.
(In reply to comment #5) > Who can reproduce problem on your local PC/server ? > PS : generic option till now does't works. > The script, /sbin/dhclient-script, which is run by dhclient, does not reference the environment variable that gets set for "nogateway": PEER_ROUTERS. Actually, examining the script reveals that is has no options to disable setting the default router up at all! root@odon:/sbin>grep PEER dhclient-script if [ x$PEER_DNS = x ] || [ x$PEER_DNS = xyes ]; then if [ x$PEER_NTP = x ] || [ x$PEER_NTP = xyes ]; then root@odon:/sbin> > --------------------net.example------------------- > # GENERIC DHCP OPTIONS > # Set generic DHCP options like so > #dhcp_eth0="release nodns nontp nonis nogateway nosendhost" > > # This tells the dhcp client to release it's lease when it stops, not to > # overwrite dns, ntp and nis settings, not to set a default route and not to > # send the current hostname to the dhcp server and when it starts. > # You can use any combination of the above options - the default is not to > # use any of them. >
Created attachment 215873 [details, diff] patch to fix the bug Here's a proposed solution to the problem: make default router setup conditional on environment variable PEER_ROUTERS. I tested it shortly, and it works for me.
Yes, I can confirm that patch works for me. Now dhclient ignores default gw from dhcp server on my second interface. Please add patch to the ebuild.
Please update to apply against 3.1.3_p1 and 4.1.x. Or note if it's not required anymore.
Created attachment 251113 [details, diff] patch for version 3.1.3_p1
Created attachment 251115 [details, diff] patch for version 4.1.0
Here you are, please, we'd like to see these applied in the ebuilds. Thanks.
ive included this in dhcp-4.2.1. dont know if anyone wants to also apply to dhcp-3.x, so i'll leave this open for now.
dhcp-4.x is stable now. dhcp-3.x is dead.
