[PATCH] Fixes for vpnc-script with Juniper VPN

[Sean Millichamp]

Hello,

I have recently started using openconnect's Juniper VPN support. It
works great (thanks!) but the vpnc-script needs a couple of minor
tweaks. Attached are two patches for vpnc-script to address two issues
I have encountered.

1) When openconnect calls vpnc-script at the termination of the session
(e.g. when a SIGINT is received) the tun0 device seems to already be
absent and as a result the /sbin/ip route commands return a 'Cannot
find device "tun0"' error for each occurance of a route deletion.

2) Juniper VPN sends a comma-separated list of multiple search domains
in the "CISCO_DEF_DOMAIN" variable (at least ours does). This replaces
the comma with a blank space, which makes it work with resolv.conf.
Given that you should never see a comma in a domain name I don't
foresee any negative impacts from this.

Thank you.

Regards,
Sean
