tested three times the vpnc.tcz, but no luck; first test with sylpheed and links open and working as well as using my config file for vpnc (which works on my ubuntu machine with vpnc):

$ sudo vpnc myconfigfile.conf
route: SIOCADDRT: Invalid argument

trying without any web service loaded and with my config file, same error message; last try without any web service and without my config file, same error. it seems to me that there is a problem with the vpnc-script file; i have another one, but can't use it since the extension is loop mounted.

... and i forgot the main point: after the error message has been displayed, i did ctrl-c in order to get back to prompt; then i would like to start links in order to post the error message; links started, but it could not connect to the web; doing it also three times, i noticed that after vpnc hangs, sylpheed continues to work (it was already open) and connects to the internet fine, but each new web-app newly open (i tried with links and opera) can't connect to the internet; sudo ping www.google.com returns the same result

Ok, I've tested vpnc.tcz again, for me it's working without any problem.

For me your error message looks like indeed a call from the vpnc-script to change the route fails on your network device. In my opinion there are some possibilities what caused this error:

1.) Problems with your network (busy device, other routes, programs trying to manage it, resolvconf, etc...)
2.) Problems relating to your special Cisco concentrator (I don't think that everyone is fully supported)
3.) Problems with the vpnc-script, which doesn't do what you need at your special configuration.

As debugging I would suggest:

1.) Run a fresh untouched version of tinycore as a guest in a Virtual Environment and load only vpnc and test it again.
2.) Execute the command "route -v" before you start vpnc, and after that. Even try to set the route manually like "route add default gw 192.168.1.1". Call dmesg and look out for other SIOCADDRT messages, as they relate to any network misconfiguration which might have been occured.
3.) If that doesn't help, extract the vpnc.tce extension and modify the vpnc-script to spit out more debugging information, where the route commands are called so that you can see, what he's trying to set.

Best regards,
Robert

thanks Robert, that was helpful and it now works. Here is what I did.

I started mc 2.3RC2 with nolocal norestore base in my bootline, and then install my internet connection (i am using a usb 3g dongle) and only load your vpnc.tcz extension with required dependencies; firstly, only running:

sudo vpnc myconffile

gave me the same error message as before, and i got after that no internet connection at all; i solved this last issue in copying back my resolv.conf to /etc which enables me to connect to the internet again; i then default the route to my vpn gateaway as you suggested with:

sudo route add default gw mydefaultgateaway

and then i restarted vpnc with:

sudo vpnc myconfigfile

and it worked, showing me a pid for vpnc and giving me access to the network at my office; i noticed that my resolv.conf was correctly modified, and moreover, as i ended vpnc by killing its pid, i saw that my resolv.conf was the usual one i am using in order to connect to the internet, which means that after vpnc ends, i can surf without beeing forced to reconnect or to copy back again my usual resolv.conf to /etc.

thank you warmely for your help and for this application.

Hi!

Is there any possibility to get this version of vpnc included?

http://svn.unix-ag.uni-kl.de/vpnc/branches/vpnc-nortel/ (described here in ubuntu formums: http://ubuntuforums.org/showthread.php?t=441042)

This vpnc also connects to Nortel vpn servers ....

Comments: If you want to use the included pcf2vpnc script you will
have to install the perl5.tcz extension once as it is not
included in the dependencies (due to size).

Put your conf to /usr/local/etc/vpnc/your.conf and
add it to your backup.

Update on update (is on the way):
- Needed again a fix for static directory declarations in source files although there's a makefile directive
- Hope to remember it next time
