Hello, I've tried to use VPNC, installed from EPEL repo (0.5.3, but no
revision number is shown). My vpnc client overrides /etc/resiolv.conf
absolutely, it doesn't append received options, it just places them instead
of old ones. vpnc-disconnect places the old resolv.conf back.
The problem is in modify_resolvconf_generic() function inside of
vpnc-script. It reads the old resolv.conf line by line and checks for
strings like "nameserver 1.2.3.4". On every match it generates a new line
with nameserver, taken from INTERNAL_IP4_DNS_TEMP variable,instead of
copying it to the new file and appending received addresses later.
For example, if I receive one nameserver address (1.2.3.4) and there are
two nameserver lines(1.1.1.1 and 2.2.2.2) in my resolv.conf, new
resolv.conf should contain only one nameserver (1.1.1.1), not three (old
nameserver address + received ones:1.2.3.4 1.1.1.1 and 2.2.2.
Regards,
Alex.
