dhcpcd error "sendto (init): Operation not permitted"
Hello all..
I have a slink box up and running pretty well with the exception of
dhcp. The purpose of this box is to act as a masquerader / gateway between
our lan and our cable modem.
I originally thought it might be a hardware problem, but I was able to
switch which NIC was configured for our lan without any problem. In the
process I found that I could make the error appear with eth0 or eth1. I
also upgraded to the potato version of dhcpcd, but that didn't help either.
I was able to find a bug listed with the Debian bug tracking system that
mentions this error. The author claims it is a problem with pcmcia and
ipmasq. However, this machine has no pcmcia devices or controller (not a
laptop). The solution given is to "recompile kernel without IP masq,"
which is not really an option for this machine. That bug can be found at:
http://www.debian.org/Bugs/db/36/36746.html
The only other thing I can think of is try to upgrade my kernel to 2.2.x,
but that brings in some other problems, and I am totally unsure if it will
work.
I really need some advice here. Any comments are welcome. Thanks.
Perhaps these logs can explain more:
