    Question Dell Netextender VPN client - OpenSUSE 13.2 cannot connect

    Hi

    I'm having an issue connecting to NetExtender with OpenSUSE.

    I am using a recent version - NetExtender.Linux.7.5.771.

    It works in Debian Stable and Kubuntu 14.04/14.10 'out the box' and due to the fact I cannot connect with openSUSE I am having to keep a copy of kubuntu just to connect to work..

    It errors during install ->

    Code:
    ./install 
    --- Dell SonicWALL NetExtender 7.5.771 Installer ---
    Checking library dependencies...
    Checking pppd...
      Do you want non-root users to be able to run NetExtender?
      If so, I can set pppd to run as root, but this could be 
      considered a security risk.

    To launch NetExtender, do one of the following:
    
      1. Click the NetExtender icon under the Applications menu
         (look under the 'Internet' or 'Network' category)
         or
      2. Type 'netExtenderGui'
    When I connect it NEVER completes the tunnel... (I have replaced the IP BTW)

    I have also tried creating the /etc/ppp/ip-up , etc (blank) files that the installer complains about and reinstalling -> still get the same issue

    Anyone able to run this on 13.2 - my user is in dialout group if that helps?

    Anyone else using this VPN software?

    Looks like VPN applications are a weak point for openSUSE

    We also have another VPN to anotherDC, this one uses Kerio control client

    http://www.kerio.com/support/kerio-control

    - this one officially only supports Ubuntu (in terms of Linux support)

    So out of 2 different VPN types i'm unable to use 100% of them with OpenSUSE, 100% work with Ubuntu. Debian 50%...

    I can see that Netextender has previously worked (with tweaks)

    I use OpenVPN with 100% success rate.

    It seems the reason is the VPN application you are using relies on old style ifup files like /etc/ppp/ip-up which are no longer used on 13.2 (due to change from traditional if-up to wicked), they are however still used on 13.1. If I were to make an educated guess, the kerio does as well.

    Yeah openVPN is great - however my company is not using that...

    Tested on Fedora 21 (workstation) - also works 'out the box'

    Any ideas how what I can do (i.e copy files off FC21/kubuntu ?) to get this to work in opensuse ?

    found this - http://usrlocalbin.blogspot.co.uk/20...onicwalls.html

    -> also didn't help..

    Well, if this is the case, anybody have any type of a resolution to this? If I could make the regular NetExtender Client work with OpenSuSE it would make things way easier for me. Currently I'm running the client on my Windows VM and connecting that way.

    My resolution to this was to no longer run OpenSUSE as my main desktop ( which is a shame)

    Fedora21, Debian Stable, Neptune OS, Kubuntu/Ubuntu 14.04/14.10 / Mint 17 all work out the box.

    In fact its only openSuse and Arch I cannot get it to work with.

    I would love to be able to connect with opensuse.

    In theory you could copy the files from 13.1, or you could just - you know - run 13.1 which still has the old if-up interface.

    Hi,
    I have a simple solution: I take the scripts ip-down, ip-up, ipv6-down and ipv6-up from the 13.1er version and put in /etc/ppp before you install netExtender. It's works fine!

    Thumbs up Re: Dell Netextender VPN client - OpenSUSE 13.2 cannot connect

    This worked like a charm. Thank you for the solution!

    I was encountering the issue under openSuse 42.1, copying the scripts from the mentioned package has resolved the problem.

    You can find the desired package here: https://rpmfind.net/linux/RPM/opensu....1.x86_64.html
