The same version of VPNC does not work on two different machines

Hello all,

Since I installed Fedora 11 on a 64 bit machine, vpnc (0.5.3)  stop
working. I get "vpnc: no response from target."

I tried google and adding "NAT Traversal Mode cisco-udp" to the config
file works for some people but not for me :(
In the system log I get this:

tun: Universal TUN/TAP device driver, 1.6
tun: (C) 1999-2004 Max Krasnyansky <maxk [at] qualcomm>
tun0: Disabled Privacy Extensions

I tried running vpnc with "strace" and it seems that there is no response to

getrusage(RUSAGE_SELF, {ru_utime={0, 13997}, ru_stime={0, 9998}, ...}) = 0

that in my Fedora 10 (32 bit) machine is

time(NULL) = 1245873098
times({tms_utime=6, tms_stime=1, tms_cutime=0, tms_cstime=0}) = 429448320
gettimeofday({1245873098, 851055}, NULL) = 0

I have attached the output of "strace" in FC11. Can
anyone please take a look to see what can be the problem? Please :), I
am new in this mailing list.

Ciao Vitor,

not easy to read a dump from strace. Much better the dump you get with
vpnc command line flag "--debug 3".

From your strace dump I read that you never get reply from your server
or, better, you never get reply form IP 193.137.24.253
I also tryed to query this IP and got no reply too.

Could you please double check if this is really the IP of your server?
If the IP is correct, maybe the server is currently down. Please
confirm with your former VPN client.

Best Regards,
Antonio Borneo
