[vpnc-devel] man-page and vpnc-script in vpnc-0.3.3

[Michael Hunold]

Hello all,

first of all thank you for your great piece of software, vpnc-0.3.3 
works flawlessly for me.

Nevertheless I have two small suggestions:

1. The manpage "vpnc.8" is outdated. It speaks about vpnc-connect, but 
apparently this got replaced by vpnc-script. This confused me when 
trying to figure out how things work.

2. In vpnc-script, there is this section:

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

set_vpngateway_route() {
	$IPROUTE route add `ip route get "$VPNGATEWAY" | fix_ip_get_output`
	$IPROUTE route flush cache
}
------------------schnipp------------------------------

The output of "ip route get" for exmaple looks like this:

 > ip route get 192.168.0.1
192.168.0.1 dev eth0  src 192.168.0.20
     cache  mtu 1500 advmss 1460 metric 10 64

The regular expression apparently is used to remove the "cache" and 
"metric" parts of the output.

For "metric", however, this does not work, because there is a space 
between "metric" and the first number following. So the regular 
expression should be 's/cache//;s/metric [0-9]\+ [0-9]\+//g'.

(Please note the space between "metric" and "[0-9]\+".

Perhaps this has worked with some versions of "ip", but the version used 
in Fedora Core 4 does not like it.

Please CC me if you reply to this mail because I'm not subscribed to the 
mailing list.

Best regards
Michael Hunold.
