No tun module in 10.04 breaks my vpn client

[aravinds]

Wrong code. That builds the fake module, but doesn't install it where modprobe can find it.

Fixed, thanks

Thanks!

Backed out the changes and replaced Openjdk but now Juniper now telling me "JRE not installed/Java is disabled." i.e. worse than when I started (modprobe error)

sun-java6 is in the partner repo. You need to enable it.

sed -e 's/# *deb \(.*\) lucid partner/deb \1 lucid partner/g' /etc/apt/sources.list|sudo tee /etc/apt/sources.list
sudo apt-get update
sudo apt-get install sun-java6-plugin

Have it sorted out and now connecting via Juniper. Thanks all

Thanks to cdenley for the help here. I am now able to use Juniper's Network Connect over SSL.

It took the combination of cdenley's work creating the tun mod, the removal of Open Java, and the installation of Sun Java to get me up and running.

I have no idea. The only VPN client I ever used in ubuntu was openvpn from the repos. I haven't used in lucid yet, but I doubt it requires my sloppy workaround. I don't know what any hamachi commands do.

FYI openvpn requires the sloppy workaround, fixed it, thanks

Alternative solution is out there aswell, Using Juniper Network Connect on Ubuntu.

This method has worked very well for me on both 32 and 64 bit installs of 10.04.

I think I have better solution that will work even for future kernels without recompilation.

echo -e "install tun /bin/true\n" > built-in.conf
sudo cp built-in.conf /etc/modprobe.d/

Hi all,

You guys are finding a solution for a nonexisting issue. Juniper's SSL VPN Network Connect works well with tun built into the kernel. It just shows up a warning ‘modprobe for tun failed’ and that's all. Believe me, I've been using (well, and selling) it since 2006, time when I was young enough to compile linux kernels for myself.

Cdenley's code is, though useful (thanks, cdenley!), just a way to shut up the warning. Nothing else. You'll most probably see ‘session timeout’ warning the next and NC session will terminate.

The real issue is that Sun Java was moved from official Ubuntu distribution. Juniper NC doesn't want to work with OpenJDK. The solution is here (and it is quite simple).
Just add/uncomment the following in your /etc/apt/sources.list:

deb http://archive.canonical.com/ubuntu lucid partner

and say

sudo apt-get update
sudo apt-get install sun-java6-jre sun-java6-bin sun-java6-plugin

Than restart Firefox and try to run NC.

Doesn't matter if you used cdenley's code or not.

BTW, you guys have became too choosy (sorry). Sun Java had not been a part of loads of distros for ages and it had never been a problem to get it even under Slackware.

PutTheBlack's link (http://mad-scientist.net/juniper.html) is also worth to check. Specially if you run _64 (not really a Juniper's fault. 64-bit Java does not support Applets even for Windows).
