    Re: HOWTO set up Juniper Network Connect VPN on Ubuntu Dapper

    I get the following error after upgrading from Ubuntu 12.04 to 12.10:

    Code:
    ncsvc> Failed to setuid to root. Error 1: Operation not permitted
    java: ncui.cpp:262: void NCUI::run(): Assertion `m_conn->isConnected()' failed.
    Aborted (core dumped)
    I am using jdk1.6.0_33_ia32

    It worked fine before the upgrade.

    Running the Mad Scientist script as sudo in 12.10 works and I don't get the above error.
    $sudo ./junipernc.sh --root

    Therfore, I believe the entire problem is
    Code:
    ncsvc> Failed to setuid to root.
    I'm not sure why this fails in Ubuntu 12.10, I believe I have the permissions set correctly on ncsvc as far as I know:

    Code:
    -rws--s--x 1 root     root     1281948 Oct 25 16:40 ncsvc

    Re: HOWTO set up Juniper Network Connect VPN on Ubuntu Dapper

    In quantal, after apllying all patches, new problem appears. Cannot launch network connect any more. When launching NC.jar manually, following errors appears:

    * SecureLaunchNCLoader * Error loading message strings: java.lang.Exception: Error reading nclaunchmessages.pl
    *** Property [msgNCTitle] with defaultValue [Network Connect] does not exist or may not have been translated ***.
    *** Property [msgTabNameSession] with defaultValue [Session] does not exist or may not have been translated ***. ...

    Full output in attachement.
    Does anyone have similar problem?

    Unfortunately some sigfault occured.

    Re: HOWTO set up Juniper Network Connect VPN on Ubuntu Dapper

    This obviously has something to do with eCryptfs and that it doesn't allow setuid (anymore? - worked in 12.04). I have posted a question at Ask Ubuntu here and I'm hoping to find a way to hack SUID support to ecryptfs again.

    I made it work again by copying my ~/.juniper_networks folder to e.g. /opt/juniper and by changing the $JNPATH variable on line 1817 in the script to the following:

    Code:
    $JNPATH = "/opt/juniper/.juniper_networks";
    Remember to keep the folder permissions intact (use cp -a when copying).

    The GUI doesn't seem to be updated and doesn't show any stats or that it's connected at all, but if you run ifconfig and the tun0 interface is up and running with a VPN IP, then it's working.

    Disconnecting doesn't work with the GUI, obviously, so you just have to kill the ncsvc process to terminate the connection.

    It's not a perfect workaround, but at least it works.

    So I tried the new version of the script. I like the fact that it gets Java out of the loop. It works fine on the 64-bit system, but for the 32-bit system it is getting stuck somehow. It says "connecting."

    In .juniper_networks/network_connect/ncsvc.log I see:

    IpcConn.error bind failed to port 443. Error 98 (ncipc.cpp:75)

    and then a bunch of

    Any ideas? Firefox is able to connect.
    So, I don't know why Firefox was able to connect, but I seem to have lost that workaround when I moved to 64-bit 12.10. I could have installed 32-bit Firefox, but I wasn't in the mood.

    I guess from the error message it should be obvious that the difference between the machine that worked and the one that didn't was that one was running a web server and the other wasn't.

    I seem to have got around the problem by adjusting the Listen commands in /etc/apache2/ports.conf to listen on port 443 only on the external interface, not on the local interface.

    I changed "Listen 443" to "Listen xx.xx.xx.xx:443" where xx.xx.xx.xx is the address of the network interface, which happens to be eth4.

    I don't know why ncsvc needs that port when run from msjnc but not when run from Firefox.

    Bytes Sent but Never Received - Connect from Behind Proxy

    I am trying to connect from a work site to a remote network. I use an Ubuntu VM (12.04) that must connect to the work network through a proxy. I successfully get connected but I cannot seem to get to any of the machines. On the Network connect GUI bytes sent ticks up but bytes received returns 0. Looks like the VPN host is using Network Connect 7.1. NC works fine from the Windows environment and both the VM and Windows machine when not behind the proxy.

    Has anyone had any experience with this? I have been having difficulty finding any workaround.

    Code:
    /usr/local/jre1.7.0_09/bin/java -jar ~/.juniper_networks/network_connect/NC.jar -h <host> -u <vpn user> -r "<Realy long realm name>" -f <X509 DER Format cert> -y <proxy host> -z 8080 -d <ProxyDomain> -L 5 -l 5 -s <proxy user> -a <proxy pass> -p <vpn pass> &

    Using a 32-bit chroot works, but is quite cumbersome.

    After a lot of investigation and trial and error, I realized that the - only - problem is that ~/.juniper_networks/network_connect/libncui.so is a 32-bit library, thus it cannot be used by 64-bit Java.
    Shame on Juniper that they do not provide a 64-bit version of the library! This would be the only thing they'd need to do to support 64-bit Linux systems out-of-the box.

    First note that JNC will only work with the Java Runtime Environment from Sun/Oracle. In case your installation uses another JRE as default, you may use the command sudo update-alternatives --config java to switch to java-6-sun.

    My workaround for a 64-bit installation is as follows.

    Additionally install the 32-bit variant of Java: aptitude install ia32-sun-java6-bin .
    Assuming that Java is installed at /usr/lib/jvm/java-6-sun/jre/bin/ and at /usr/lib/jvm/ia32-java-6-sun/jre/bin/ ,
    rename /usr/lib/jvm/java-6-sun/jre/bin/java as /usr/lib/jvm/java-6-sun/jre/bin/java.orig and
    save the following shell script as /usr/lib/jvm/java-6-sun/jre/bin/java :

    Code:
    #!/bin/bash
    if [ $3x = "NCx" ]
    then
        /usr/lib/jvm/ia32-java-6-sun/jre/bin/java "$@"
    else
        /usr/lib/jvm/java-6-sun/jre/bin/java.orig "$@"
    fi
    This script should be readable and executable for all. It will call the 32-bit variant of Java when launching Network Connect (and otherwise call the default 64-bit variant).
    Thank you so much! I have been messing with this for about an hour...

    Re: HOWTO set up Juniper Network Connect VPN on Ubuntu Dapper

    I was still having problems with this after following this doc:
    http://kb.juniper.net/InfoCenter/ind...ent&id=KB25230

    It was the same segmentation fault shenanigans that avira was experiencing. After much research, I found that manually supplying the ssl certificate and realm from the command line made everything happy.

    I even came across an excellent tutorial for using network connect in an entirely non-gui way at this link:

    http://makefile.com/.plan/2009/10/ju...olved-mystery/
    many props to scott for being a genius

    I personally like the gui window and thus have created this bash script to make it cooperate:

    Code:
    #!/bin/bash
    #
    # 01-30-2013 RobertKempton
    # this script will launch the juniper network connect java client with the given paramters
    # if you don't know your realm, open your juniper site in your browser (don't log in)
    # right click on the page, choose view source
    # search for realm. The value field in the same html tag is your realm
    #
    # This script will also automatically download the ssl certificate for you
    ##
    
    #make sure network connect is actually installed
    if [ ! -f $HOME/.juniper_networks/network_connect/NC.jar ]; then
        echo "Juniper Network Connect is not installed for the current user"
        exit
    fi
    
    #check if 32bit java is installed
