FreeBSD revenant.fok 6.0-RELEASE-p3-fok1 FreeBSD 6.0-RELEASE-p3-fok1 #1: Mon Jan 23 12:27:53 CET 2006 fok@revenant.fok:/usr/obj/usr/src/sys/REVENANT i386
>Description:
ppp fails establishing a PPPoE connection when using a renamed network interface. Could be a bug in ppp or netgraph.
>How-To-Repeat:
/etc.rc.conf:
[..]
ifconfig_sis1_name="dsl0"
ifconfig_dsl0="up"
[..]
/etc/ppp/ppp.conf:
default:
set device PPPoE:dsl0
[..]
ppp command line: /usr/sbin/ppp -quiet -ddial -nat default
/var/log/ppp.log:
[..]
Jan 24 16:00:14 revenant ppp[223]: Warning: dsl0: Cannot send a netgraph message: No such file or directory
Jan 24 16:01:14 revenant ppp[223]: Warning: deflink: PPPoE: unknown host
Jan 24 16:02:14 revenant ppp[223]: Warning: deflink: PPPoE: unknown host
Jan 24 16:02:14 revenant ppp[223]: Warning: deflink: Device (PPPoE:dsl0) must begin with a '/', a '!' or contain at least one ':'
Jan 24 16:02:14 revenant ppp[223]: Chat: Failed to open device
[..]
However, changing /etc/ppp/ppp.conf to use the original interface name ("set device PPPoE:sis1")establishes a connection, but there are still some issues since sis1 should really be addressed as dsl0:
/var/log/ppp.log:
Jan 24 16:13:11 revenant ppp[692]: Error: iface_ChangeFlags: ioctl(SIOCGIFFLAGS): Device not configured
Jan 24 16:13:11 revenant ppp[692]: Warning: deflink: Failed to set the IFF_UP flag on sis1
>Fix:
Workaround: Don't rename the interface which is used by ppp and everything works just fine.
