HOWTO set up Juniper Network Connect VPN on Ubuntu Dapper

[kasulstyls]

Ok got it. to resolve the DSSSL_load_so failed I ran the command on the first post by Madscientiest sudo ln -s libssl.so.0.9.8 /usr/lib/i686/cmov/libssl.so.0 and now I connect fine.

I would also like to point out that when you first install, the java network connect window didn't popup. I looked through the posts and installed http://debian.mirror.inra.fr/debian/....4-27_i386.deb thanks to post #205 Baltazar72.


Thanks again Madscientist and thanks to all within this forum.

I was getting the following error when executing the junipernc script on Ubuntu 8.10...

Exception in thread "main" java.lang.UnsatisfiedLinkError: Can't load library: /usr/lib/jvm/java-6-openjdk/jre/lib/i386/xawt/libmawt.so

Could not find the main class: NC. Program will exit.

It seemed pretty obvious why - I didn't have an xawt directory under that path, but did have that file in another path. Did a quick ln -s as follows...

user@host:/usr/lib/jvm/java-6-openjdk/jre/lib/i386$ sudo mkdir xawt
user@host:/usr/lib/jvm/java-6-openjdk/jre/lib/i386$ cd xawt
user@host:/usr/lib/jvm/java-6-openjdk/jre/lib/i386/xawt$ sudo ln -s /usr/lib/jvm/java-6-openjdk/jre/lib/i386/headless/libmawt.so libmawt.so


Now I get a shiny new error... Have no idea how to fix this one. Perhaps I need to link more parts of JRE into the folder I created?
user@host:/$ junipernc
Xlib: extension "RANDR" missing on display ":0.0".
Exception in thread "main" java.lang.UnsatisfiedLinkError: java.awt.Component.initIDs()V

Many thanks for any help that can be offered...

Update - Fixed my own problem. I hope this can help someone else someday. I removed the symlink I created and ran the following command to get Java straightened out.

sudo update-java-alternatives -s java-6-sun

Is this howto obsolete since network-manager has a "plugin" called network-management-vpnc?
"This package provides a VPN plugin for vpnc, providing easy access Cisco Concentrator based VPN's."
If yes: is there a way to figure out how to access the VPN-Server from my university?

Since this howto is for setting up Juniper Network Connect VPNs and the comment you quote is for setting up Cisco Concentrator VPNs, no, I don't think this howto is obsolete due to network-management-vpnc.

However, I don't know much about Cisco VPNs and I know even less about network-management-vpnc, so I can't say 100%.

Ok
I didn't know there was a difference

Thanks. Buellman

All,

For people who have upgraded to 8.10 and have lost a previously working client try epiphany (a browser). I was able to get MadScientist's scripts to work for FireFox, but if you want to just use a browser try that one.

sudo aptitude install epiphany-browser

There is a game called epiphany, so make sure you use epiphany-browser

then just call the browser and go to your VPN website.

epiphany

Who's got this working in 8.10? What client do you use, and what changes did you do it (if any)?

In Firefox I get to the point where it is supposed to install the client, and after that the browser just hangs and I have to kill it.

I am using ncui_1.2-2 and Java 1.6.0_10

Hi, have Juniper Network Connect working on Ubuntu 8.10.

I've upgrade from 8.04 and after the upgrade it was still working.

[realflash]

I have this working in 8.10. It was working in 8.04 (no manual changes necessary), then I upgraded to 8.10 and it hung like yours.

I fixed it by rolling back from Sun JRE 6u10 to 6u7 (the previous version - there wasn't a u8 or u9 it seems).

I proved it worked by using apt to remove sun-java6-bin etc and then dpkg -i on the same packages from 8.04. However, that meant that every apt-get upgrade took the JRE back to 6u10. I think you can 'pin' certain packages so they don't get upgraded, but in the end I overrode FireFox's plugin. By default the plugins in /usr/lib/mozilla/plugins will get used, but $HOME/.mozilla/plugins also gets read. The /usr one seems to override the /home one, weirdly. So I:

1. Removed the package sun-java6-plugin
2. Downloaded 6u7 JRE from sun
3. Extracted it to a directory in my $HOME
4. linked jre/plugin/i386/ns7/libjavaplugin_oji.so in my $HOME/.mozilla/plugins

Next time you start FF, it will use the Java linked in your $HOME rather than /usr/lib. You can verify your Java version in use at http://www.javatester.org/version.html
