Hi Mark,

It looks like Quagga is compiled and working okay.  I have a silly little
program that can be used to see if the Linux MD5SIG support is working:


I have tested it on a stock Ubuntu 7.04 and it works a treat:-

leigh at toaster:~$ tar xzf linux-md5sig-test-0.1.tar.gz
leigh at toaster:~$ cd linux-md5sig-test-0.1/
leigh at toaster:~/linux-md5sig-test-0.1$ make
cc -g -Wall   -c -o client.o client.c
cc -g -Wall   -c -o functions.o functions.c
cc -g -Wall -o client client.o functions.o
cc -g -Wall   -c -o server.o server.c
cc -g -Wall -o server server.o functions.o
cc -g -Wall   -c -o torture.o torture.c
cc -g -Wall -o torture torture.o
leigh at toaster:~/linux-md5sig-test-0.1$ ./server 2345 mypassword &
[1] 8018
leigh at toaster:~/linux-md5sig-test-0.1$ ./client 2345 mypassword connected
test connection closed

If you have two ubuntu boxes you can run a session between the two and
use tcpdump to confirm the signature is present.

Let me know if that works or not.
