Problem with connecting using f5 vpn on Ubuntu/Linux; stuck on "Connecting..."

Forums Technical Forums
1

This issue happens only on the machine I’m using, I treid the same account on multiple other machines, on the same network and other networks. The gist of it is that f5vpn gets stuck in the connecting phase and doesn’t modify my routes table or hosts file, as it should.

The server is started successfully and establishes a connection on port 44444, but that’s where it stops.

Did anyone face a similar issue? I have the log files (vpn.log, svpn.log, syslog, etc..) if anyone is interested to take a look. I tried creating a support case, but I only had the “NginX” product family displayed. I would really appreciate any help.

Do you see any obvious errors in the log files?

What do you see in svpn.log when you compare a working system to your not working system? Presumably the logs must be different between the two. The difference should help narrow down what the issue might be.

You might also review Ubuntu’s AppArmor settings or temporarily disable it, as these might block networking changes that the f5vpn process is trying to perform:

Hi Lucas! thanks for the reply 
I’ll start with the syslog

The only difference with a working system is that last line, for a working system, it prints
```
NetworkManager-dispatcher.service: Disables successfully.

As you can see, it stops at “connecting…”, while on a system where it works, it connects right away and displays “Tunnel /Common/<VPN_GROUP>(2) connected” after that line. I’ll split this reply due to message size contraints

Something worth noting is that I could patch the hosts file manually, add manually add some routes to my ip table pointing at vpn (at tun0 address) and I would connect to those specific domain names, however I wouldn’t be able to receive callbacks from them, and f5vpn would still display connecting state.

6

Here is a pastbin contaning my previously posted replies, since this forum unfortunately does not support txt files.

7

Oh, and I forgot to mention, I couldn’t track down any obvious errors in the log files. Messages just stop.

8

Update: I checked AppArmour out, tried disabling and tried putting the NetworkManager profile in complain mode, but nothing changed. Same exact result as above.

9

Hmm. From those logs, it seems like it’s actually connected. From the syslog you pasted though, there do seem to be a few errors from QT. The client uses QT to write the messages into the client GUI. Perhaps you could try to reinstall it, and dbus-daemon.

Is this something that you think we could reproduce in a lab on a fresh ubuntu system, or is it something that seems tied to this client PC specifically?

10

I can’t think of anyway to reproduce it. I probably somehow modified something on my system, because it works on every other device I tried. In fact, it event works inside a docker container running on my system. I just found out this weird thing:

- If I attach the container to host network, f5vpn won’t connect

- If I DON’T attach the container to host network, f5vpn WILL connect

So, in the case where it connects from within the container, I again modified the routes table to point the specific ips configured by f5vpn to the container itself, but even though my traffic goes through and I can actually reach those few websites, I still can’t receive callbacks from a particular remote server like I can if I connected.

Does f5vpn/BIG-IP somehow check if the source ip is something it has registered? I don’t have any idea what happens on the provider side.

I can’t think of any solution short of nuking my ubunut and re-installing it. I haven’t tried reinstalling dbus, I’m afraid of breaking something else in my system, since it seems like a sensitive service.

As for Qt, I haven’t tried reinstalling it yet, but the few errors it prints are identical to those printed in systems where it worked.

Oh, and apologies, I forgot to mention that I’m running vpn version 7220.2022.0308.1, thought it seems like the most recent version anyway.

Are there any configuration, software versions, firewall rules, etc… you wish to take a look at?

11

Oh, and f5vpn brings its own Qt libraries along as it seems. They are stored in /opt/f5/vpn/lib

$ ls /opt/f5/vpn/lib<br>libcrypto.so.1.0.0 libicui18n.so.55 libQt5Core.so.5 libQt5Gui.so.5 libQt5OpenGL.so.5 libQt5Sql.so.5 libQt5WebKitWidgets.so.5 libQt5XcbQpa.so.5<br>libicudata.so.55 libicuuc.so.55 libQt5DBus.so.5 libQt5Network.so.5 libQt5PrintSupport.so.5 libQt5WebKit.so.5 libQt5Widgets.so.5 libssl.so.1.0.0

12

I wonder if this does have to do with routing, and maybe once the VPN is connected it interrupts the routing table: Can you try to create another VPN resource on the BIG-IP server that is set for split-tunnel but use a different small IP address range, like 10.0.0.0/24 and a lease-pool within that network. Maybe the connection will behave differently on a different routing subnet and/or not a full-routing tunnel.

13

Unfortunately the BIG-IP server is managed by another company, we are only granted access to the vpn to access their resources. f5vpn is started from the browser, and the log in workflow is protected by 2FA.

Just as a reminder, my account works on other similar machines on the same netwroks. I just thought about contacting one of their network adminstrators, do you think their server might be refusing to accept my machine? is there such a thing in BIG-IP, where a server refuses/drops/ignores attempted client connection because of some configuration client side?

14

I have the same problem since upgrading my Ubuntu Distro. And like you, works in containers hosted by the problematic machine.

15

My problem disappeared after I installed Ubuntu 22. I don’t know whether it went away because I upgraded our because I wiped my device, giving it a fresh start.

16

Nice to know, I might try a fresh instal then.

17

Tried multiple “solution” found accross the web with no chance.
Made a fresh install of 23.04 and started working as before.

Unfortunately I have no good guess of what it was, better chance to the next one.

18

Same problem here with “5.15.0-78-generic #85~20.04.1-Ubuntu SMP Mon Jul 17 09:42:39 UTC 2023 x86_64 x86_64 x86_64 GNU/Linux”, it’s start failing.

Some different details is that i have to eth ifaces in my desktop in different net segments, at first attemps it’s seems to be resolved, disabling one of them, but now is always failing with the same logging info, the network is connected but can’t finish de routing keeping in bucle with

“2023-07-31, 0:43:22:944, 43256,43257,svpn, 48, , 803, CLinuxRouteTable::GetBestRoute2, 1.1.1.1

19

After some research i workarounded using openconnect client, extrating session id from the initial request after logon in navigator and connected.

echo MRHSession=0123456789abcdef0123456789abc | sudo openconnect --protocol=f5 --cookie-on-stdin SERVERNAME

Please fix the root error.

20

Faced the same issue in my Ubuntu 20 LTS. Not sure what exactly caused the issue, but something related to Docker Networks messed up the working VPN setup. “docker network prune” command followed by a system restart resolved issue for me.
