Vpnagentd crash on Linux

michal.liptak · ‎09-23-2014

I'm experiencing vpnagentd crashes on my Linux machine, in the syslog I can see:

[155229.713035] traps: vpnagentd[366] general protection ip:7f31cebfb5bf sp:7f31ccc9dfe8 error:0 in libstdc++.so.6.0.20[7f31ceb8c000+ec000] [120772.735031] traps: vpnagentd[2453] general protection ip:7fb67ae115bf sp:7fb678eb3fe8 error:0 in libstdc++.so.6.0.20[7fb67ada2000+ec000] [139790.130545] vpnagentd[5079]: segfault at 100036e ip 00007f149dc1bd6e sp 00007f149ac80ff0 error 4 in libvpnagentutilities.so[7f149dba4000+ce000]

This of course disconnects my VPN connection. How can I diagnose the issue?

Thanks.

I have the same issue.

[11255.835877] traps: vpnagentd[3456] general protection ip:7f4ca86d3e9f sp:7f4ca646efe8 error:0 in libstdc++.so.6.0.20[7f4ca8664000+f0000]

Sometimes running

killall cisco-vpnui

/etc/rc.d/vpnagentd stop

/etc/rc.d/vpnagentd start

cisco-vpnui

might fix it, but this is not always the case. Sometimes it causes the whole system internet to stop working. In this case, you may need to reset your internet connection. On my computer, it can be done as such,

sudo ip link set enp7s0 down

sudo ip link set enp7s0 up

note that the name of the interface (in my case enp7s0) varies by computer and not all Linux distributions use ip link. I would appreciate if Cisco would acknowledge the issue and fix it since this happens quite frequently and is a severe pain to deal with each time (especially when running applications like MATLAB that require access to the licensing server).

Hi there everyone just reporting back to advise you of the absolute subtle genius of Cisco! Of course none of their staff are allowed to actually say that there is an alternative out there for Linux but through their SHEER SILENCE they have successfully communicated to me - and now you too! - that we shouldn't be using the AnyConnect client on Linux anyway!

After upgrading from the Ubuntu Desktop 14.10 64-bit as per the above to the latest 15.04 things only got worse with the old AnyConnect. After the upgrade my 3.1.07021 client would completely fill my upload bandwidth whenever it was connected. As you can well imagine that is completely unusable but I discovered that version 3.1.08009 had just recently been released! So I thought for sure that would solve my problem, right? Wrong! Same issue with the bandwidth being used for nothing I could determine, anyway. It was so unusable I couldn't even run it long enough to find out if the new version solved the original issue I posted above TWO MONTHS ago.

So out of frustration I did some digging around and found what must be EXACTLY what Cisco staff were hoping we would find if they just ignored us long enough and that turned out to be OpenConnect!

Not only does it work, not crash, and not fill up my upload stream for no apparent reason but after installing the network-manager-openconnect-gnome plug-in it is integrated right into Ubuntu's network manager AS. IT. SHOULD. BE!!

It's beautiful and a far better solution than AnyConnect even if AnyConnect WAS working which it most definitely was not! And all this because of the absolute genius manoeuvrings of Cisco staff who must have known that if they just let us suffer long enough that we would find our way to a better world. One that does not include their Linux-based AnyConnect client.

Well played, Cisco. Well played!

I've got the same problem too since the update 3.1, luckly there's a simple

workaround :

once/if vpnclient is crashed

-find the folder /opt/cisco/anyconnect/bin

-there's a file called vpnagentd ( the vpn deamon ) just double-click it

and start again "vpnui" ( cisco anyconnect icon , you should have a desktop link too)

everything will go back to work!!!!

anyway is definitly bugged this client....
