The University of L'Aquila recently updated their infrastructure and this workaround is no longer necessary. Use ancwrd1/snx-rs instead. Should you need it, you can find the old README below.
The Linux client for Checkpoint VPN, snx, is a i386 executable; this container wraps it so
that it is not necessary to use a muliarch distro.
This container should be run with --net=host --privileged in order for it to
have the required rights to set up the tunnel and change your routing table.
WARNING: This container does nothing to secure snx which needs to run SETUID. Moreover it requires you to store your password in clear in a file. Use at your own risk.
Pick a folder in which to store your config files and create one using the
syntax of expect scripts
export configs=/etc/snx
mkdir $configs
cat > $configs/myconfig.exp << EOF
set servername my.server.address
set username myuser
set password mypassword\[with\}escaped\*specialCharacters
# optional the build number of snx to use: not all version will work with a
# given server. Possbilities currently are 800008209 (default) and 800007075
set build_number 800008209
EOF
Build the container
docker build -t snx --network host .
First start
docker run \
--name a_friendly_name \
--detach \
-v $configs:/etc/snx/ \
-v /lib/modules:/lib/modules:ro \
--net=host \
--privileged \
snx \
myconfig.exp
Then
docker start/stop a_friendly_name
Beware, apparently no two instances can run simultaneously: snx refuses to
change the routing table in the second instance.
set servername 151.100.70.14
