Summary: udhcp does not support ethernet aliases
Description:
I have multiple aliases for eth0 (eth0:1, eth0:2, etc.) and I run invidual
udhcpc for each interface. Every interface will get IP address, but after
a while (lease time?) when renew(?) comes, every udhcpc dies.

When it dies, It reports:
debug, Sending renew...
error, FATAL: couldn't listen on socket, No such device

I recommend you to use the version of udhcp that is in busybox. AFAIK the
stand-alone udhcpd currently isn't actively maintained as opposed to the
version in busybox.
If you do not need any other applets from busybox, then just turn them
off.

Need a bit of help debugging it. It happens here:
if (listen_mode != LISTEN_NONE && fd < 0) {
if (listen_mode == LISTEN_KERNEL)
fd = listen_socket(INADDR_ANY,
CLIENT_PORT, client_config.interface);
else
fd = raw_socket(client_config.ifindex);
if (fd < 0) {
bb_perror_msg("FATAL: cannot listen on
socket");
return 0;
Can you check that it happens in listen_socket? (Just add a printf before
it).
Next, listen_socket() itself is in socket.c. Please add this line with
'+'. What does this printf prints for you?
strncpy(interface.ifr_name, inf, IFNAMSIZ);
if (setsockopt(fd, SOL_SOCKET, SO_BINDTODEVICE, (char
*)&interface, sizeof(interface)) < 0) {
+printf("BINDTODEVICE '%s' failed\n", inf);
close(fd);
return -1;
}

I'm using it on a Linksys router, but I don't have development environment
currently installed. I'll try to set up that first for debugging.

Most likely fixed in svn. Bug is to be closed after a few weeks unless svn
is reported to not work.
