Greetings,
It seems that one can't use proxy-arp for alias interfaces. Using it for the respective real interface works fine, and this is what I have been doing this far when I have needed to use proxy-arp "manually". But now I configured ppp-server and pppd finds an alias interface when it looks for a network interface on the same subnet as the host, tries to create ARP entry and fails:
""" Oct 11 13:25:48 xxxxxx pppd[yyyyy]: found interface eth0:0 for proxy arp Oct 11 13:25:48 xxxxxx pppd[yyyyy]: ioctl(SIOCSARP): Operation not supported by device(19) """
This is unfortunately a lot more problematic as I can't force pppd to use some hardwired interface (except by modifying the source). Which one actually is guilty, pppd or the kernel? Is this how kernel is intended to work? In case I'm missing something obvious, do inform me.
The machine is our production server so I'm still using 2.1.117ac3. pppd is 2.3.5.
TIA, //Hannu
