vpnc-0.3.2 fails to set default route due to a bug in vpnc-connect

vpnc-connect reads ouptut of /sbin/ip command and then after "fixing" it feeds
it back to the /sbin/ip
unfortunatey the "fixing" went wrong and /sbin/ip could not accept the given
parameters

Reproducible: Always
Steps to Reproduce:
1. set up the network interface
2. start vpnc-connect
Actual Results:  
an error message appears from /sbin/ip

route -n 
does not contain the default route it should (including gateway address)


Expected Results:  
no error messages
proprly working routing

after correcting fix_ip_get_output() function within vpnc-connect to the form
cited below:

fix_ip_get_output () {
        sed 's/cache//;s/metric \+[0-9]\+ [0-9]\+//g' | xargs echo
}

it works again...

Paul, do you know if vpnc-0.3.3 fixes this problem?

[Comment 2 Tobias Sager 2005-08-17 08:11:26 UTC]

Forget the question. I have two new ones:
- Is this still an issue?
- What's your iproute2 version?
- What's the output of `ip route get $YOURGATEWAY`?

1/ 
it is not an issue as long as I have 
fix_ip_get_output () {
        sed 's/cache//;s/metric \+[0-9]\+ [0-9]\+//g' | xargs echo
}
in my ebuild...

# ip route get XXX.XXX.XXX.XXX

This is still an issue in vpnc-0.3.3, the fix mentioned here works for me.
