The basic fix is supplied at your own risk. Luckily the user kazersozet posted a fix which I’m copy and pasting below. This is because the generic kernel was shipped without the tun.ko module that snx (and many other vpn’s ) use to create a virtual network interface. I got the error message that there is no tun available. Until you update to kernel 2.6.32-21-generic which happened to me when I updated to Kubuntu 10.04 LTS. Shouts go out to Husain Al-Khamis for this one.

One extra step is to also install the 32 bit libstdc libraries as snx is compiled as a i386 application. The steps above are the same except that you need to first install the amd64 version of gcc 3.3 as well. Until you try and do this on an AMD64/x86_64 computer. Nothing too strange there so I then installed the package $ dpkg -i libstdc++5_3.3.6-17ubuntu1_b I extracted the debian package first to see what I was about to install. To get around this on ubuntu download an older package. On Debian Sid you can simply install the correct library $ aptitude install libstdc++5 We have the famed snx: error while loading shared libraries: libstdc++.so.5: cannot open shared object file: No such file or directory bug. Now we get onto the if things don’t go well – which for me has been the default scenario. If all goes well then you should see the SNL login screen as shown here: Check Point's Linux SNX

This shell script contains an embedded tar file which installs the snx binary as /usr/bin/snx. Or if you want a bit more feedback you can run sh +x. The install is easy enough, just run the install script. The first thing you need is the software itself which you will need to get from Checkpoint. The binary is called snx and it works quite reliably after you get over the problems of getting it installed. There is a Linux client for Checkpoint’s ssl extender vpn. I have released an update to this blog post: See CheckPoint SNX install instructions for major Linux distributionsĪnother in my series of 6 months from now posts.
