network connect, won't start

[ Edited ]

I'm running into problems trying to VPN to my work place with Juniper network connect. Also using firefox on gentoo. I was hoping someone might have an idea of what's happening. Here's as much info as I could find.

 Here's my ./dsHCLauncher_linux1.log. This seems to show the prob, but now sure how to fix it.

 Here I'm running the .juniper_networks/network_connect/ncdiag and even though there's lots of ping failures, I get out on the internet just find w/ this machine.

Re: network connect, won't start

Does the Network connect Client work if you disable  the hostcheck for this specific role.

Re: network connect, won't start

Not sure how to disable the "hostcheck for this role". I'm not the admin. Just trying to log into my place of work. They don't know much about linux.

When I get to the page that shows "Network Connect" under "Client Application Sessions" in firefox, I then press the "start" button, but the same page just reappears.

Re: network connect, won't start

Are you running 64bit Gentoo?

NC does not work on 64bit Linux. I had to run 32 bit with PAE.

Re: network connect, won't start



You will need to talk to the SA admin as the Host Checker is probably searching for Windows-specific components.  If they agree to allow Linux to connect with Network Connect to the network they should configure the SA to allow it, the HC for Linux can check Ports, Processes and Files while HC for Windows has many more checks it can perform.


From http://www.juniper.net/techpubs/software/ive/admin/6.5-IVEAdminGuide.pdf


You must explicitly create policies for each operating system you want to

allow. For example, if you create a Windows Host Checker policy, but don't create

one for Mac or Linux, users who sign into the IVE from a Mac or Linux machine

will not comply with the Host Checker policy and therefore will not be able to

access the realm, role, or resource on which you enforce Host Checker."




On Linux systems, Host Checker is not supported when launching Network

Connect through ncsvc."


Check http://www.juniper.net/techpubs/software/ive/releasenotes/SA-SupportedPlatforms-65.pdf to see what are the Supported Platforms for the 6.5 version the SA you are connecting to is running.


If there is difficulty getting NC to connect they could try enabling JSAM access for Linux.
