Problem:
The Shrew Soft VPN Access Manager overwrites the /etc/resolv.conf on
Ubuntu. That is a plain text file that holds ip addresses of
nameservers. If the connection fails multiple times, the file does not
change back and domain names can't be resolved any more.
To reproduce:
Connect to an overburdened or weak WiFi-network and keep refreshing the
vpn connection. If it fails multiple times, the /etc/resolv.conf is
overwritten. Confirm that by issuing `cat /etc/resolv.conf`. If you try
to connect to a different network at any later date, domain names can't
be resolved.
Quick and dirty fix by Hand:
Clear everything from /etc/resolv.conf except the comments and put in
the ip address of your ISPs DNS server. If you don't know it, you can
also use Googles DNS service, but that may be a privacy hazard. Info on
the file: https://en.wikipedia.org/wiki/Resolv.conf
Client Version: 2.2.1
OS: Ubuntu 16.04 LTS
I don't have a logfile.
