Re: dhcrelay multiple instances possible bug
Hi Riccardo,
dhrelay only operates on a single interface, so you're not missing anything
there.
Can you show me the ps output for the dhcrelay processes you start? The rcctl
commands you show below don't include the rcctl start dhcrelay and
dhcrelay_second bits.
I have the following in rc.local (mostly because this config predates rcctl):
foo=192.0.2.194
bar=192.0.2.196
echo -n 'start dhcp relays:'
for i in vlan371 vlan373 \
vlan835 \
vlan801 vlan847 vlan866 vlan867 \
vlan811 vlan815 vlan816 \
vlan1101 vlan1147 vlan1165 vlan1166 \
vlan1201 vlan1231 vlan1247 vlan1265 vlan1266 \
vlan1301 vlan1331 vlan1347 vlan1365 vlan1366 \
vlan971 vlan966 \
vlan1401 vlan1465 vlan1466 vlan1467 \
vlan1501 vlan1565 vlan1566 \
vlan1601 vlan1647 vlan1665 vlan1666 vlan1667 \
vlan1701 vlan1747 vlan1765 vlan1766 \
vlan1801 vlan1865 vlan1866 \
vlan1901 vlan1965 vlan1966 \
vlan2001 vlan2065 vlan2066 vlan2067 \
vlan2008 vlan2068 \
vlan2506 vlan2533 vlan2536 vlan2531 vlan2537 vlan2547; do
/usr/sbin/dhcrelay -i ${i} $foo $bar
echo -n " ${i}"
done
echo '.'
Which produces:

dhcrelay multiple instances possible bug
Hi there, many years that i don't use this ml. I'm Riccardo writing from Spain, nice to meet you guys. First of all, many compliments for the exceptional hard work that you've done in the OpenBSD development. Just, thank you. Next a possible bug: In the OpenBSD dhcrelay(8) implementation i cannot find an option to specify different interfaces in a single daemon instance, try to image a router with multiple vlans and a dhcpd server in other machine in an internal service dedicated routed ip network segment. The first instance is executed by the command: rcctl enable dhcrelay rcctl set dhcrelay flags "-i vlanxxx DST_ADDR" The second one i've done this workaround: cd /etc/rc.d cp -p dhcrelay dhcrelay_second rcctl enable dhcrelay_second rcctl set dhcrelay_second flags "-i vlanyyy DST_ADDR" Now if i open a tcpdump session in the router and in the server and i configure correctly the dhcpd in the server i notice that traffic from the dhcrelay_second to the dhclient host in the vlanyyy isn't correctly forwarded. And it is not a pf problem. The strangeness is that if i don't execute the relay from rcctl but i execute with: dhcrelay_second -d -i vlanyyy DST_ADDR it works like a charm. If you want more debug or pcap files or access to the machines there's no problem at all. Thank you to spend your time, nice regards, RG -- Name: Riccardo Giuntoli Email: tag...@gmail.com Location: Canyelles, BCN, España PGP Key: 0x67123739 PGP Fingerprint: CE75 16B5 D855 842FAB54 FB5C DDC6 4640 6712 3739 Key server: hkp://wwwkeys.eu.pgp.net
