Using Juniper Network on Ubuntu 32 and 64 bit without Firefox

Lately i have moved from Ubuntu 32bit to 64bit to make use of the 8G memory, and since I have been struggling to get our juniper vpn connection working, turned out it is not compatible with 64bit binaries of java and firefox.

I found this great tutorial here to have the juniper network VPN working from command line http://mad-scientist.us/juniper.html

the only disadvantage of this is you won’t have a status window to monitor the connection activity.

This has been tested on Ubuntu 10.10 maverick.

Installing Zend Server on Ubuntu 10.04

I have been having issues trying to install Zend Server on Ubuntu 10.04 following the steps here http://files.zend.com/help/Zend-Server-5-Community-Edition/zend-server.htm#deb_installation.htm
the problem was because there is a missing dependency for the “libmysqlclient15off” MySQL client library

to solve this, I had to install “libmysqlclient15off” from here (select the one that matches your architecture)

http://archive.ubuntu.com/ubuntu/pool/universe/m/mysql-dfsg-5.0/

Then install it using the command line :

dpkg -i libmysqlclient15off_5.1.30really5.0.83-0ubuntu3_i386.deb

after that running the installation for Zend server from through repositories, will work with no interruptions.
