Cisco AnyConnect VPN Client on 64-Bit LinuxMint 11

I've posted before about getting Cisco AnyConnect running on Ubuntu 9.10 and Ubuntu 10.04, but I've since started using LinuxMint as my daily driver and did a clean install of MInt 11 today. Mint is based on Ubuntu so on Mint 10 the previous strategy to get AnyConnect running worked fine, but I had to take a different approach after installing Mint 11. (I suspect it'll be the same issue on Ubuntu 11.04 but I haven't tried it.)

In doing a bit of research I came across this link that explains quite correctly that you don't need to actually download and extract Firefox to get this all working, which is what I had been doing previously. The Cisco client (for some stupid reason) expects certain things to be in a /usr/local/firefox directory but you can simply create that directory, download some other files, and then create the appropriate symlinks in /usr/local/firefox to make AnyConnect happy.

I also ran into some inexplicable weirdness related to a certificate file in my ~/.mozilla/firefox profile directory but I'll cover that as I outline the steps I took to get AnyConnect working.

Summary of Steps

Follow these and if you're lucky it'll work; if it doesn't read the information that follows for more details and troubleshooting ideas.

  1. Follow the steps in this blog post, which are as follows:

    1. sudo apt-get install ia32-libs lib32nss-mdns

    2. sudo mkdir /usr/local/firefox

    3. sudo ln -s /usr/lib32/ /usr/local/firefox

    4. sudo ln -s /usr/lib32/ /usr/local/firefox

    5. sudo ln -s /usr/lib32/ /usr/local/firefox

    6. sudo ln -s /usr/lib32/ /usr/local/firefox

    7. sudo ln -s /usr/lib32/nss/ /usr/local/firefox

  2. Download the AnyConnect installer from somewhere. The usual method of browsing to your VPN server and logging in may not work, so see below for details.

  3. Run the installer from the directory to which it was downloaded (sudo ./ The daemon may fail to start at this point but don't worry if it doesn't.

  4. If the daemon failed to start, start the VPN daemon: sudo /etc/init.d/vpnagentd_init start

    1. You shouldn't get an error regarding /opt/cisco/vpn/bin/vpnagentd not being found at this point if you followed the above steps accurately. If you do, read on to see if any ideas come out of any of the subsequent discussion.

  5. Start the AnyConnect client. It should be in your Internet programs menu.

    1. If you get a "server certificate problem" error, stop Firefox and delete ~/.mozilla/firefox/YOUR_PROFILE.default/cert8.db where YOUR_PROFILE is whatever random string Firefox assigned your default profile (you should only have one directory with .default at the end of it in ~/.mozilla/firefox). In my case this problem didn't rear its head until after I rebooted, so you might want to reboot at the end of all of this to make sure everything's working.

If you're still getting errors read on for more info ...

Downloading AnyConnect

I ran into problems right out of the gate on Mint 11. On Mint 10 as well as previous versions of Ubuntu I could at least hit my VPN server in a browser, try to fire up the Java applet, and when that fails it prompts you to download, but this time around the "launching Java applet" screen on the VPN server just hung. I verified that Java is enabled in Firefox and tested with other applets so I'm not sure what the issue is there, particularly since this did work on my 32-bit machine with Mint 11.

So word of caution: you need to get the installer elsewhere, or at least I did. There may be a solution to this I haven't yet come up with so if you know what's up here, please be sure and comment.

Luckily I had the installer backed up from when I copied my home directory to an external hard drive prior to installing Mint 11, so I ran the installer from my home directory.

sudo ./

This at least got the daemon installed for me, but it failed to start after installation (usually it starts fine after it's installed), throwing an error about /opt/cisco/vpn/bin/vpnagentd file not being found. The file's definitely there so I'm not sure what its problem is, but this gets resolved in the subsequent steps so you can ignore that error for now.

Install Necessary Libraries and Create Symlinks

See the above steps for details (all the steps under #1 above). In my case this resolved the file not found error the daemon was throwing when I tried to install AnyConnect prior to creating those symlinks. If you do that step first everything should work.

Launch the VPN Daemon

sudo /etc/init.d/vpnagentd_init start

If that throws errors doublecheck all the symlinks you created above. Note that in previous versions one of the things you were supposed to install and symlink to was but that does not seem to be necessary.

Launch the AnyConnect Client

You should now be able to launch AnyConnect from your Internet programs menu. If you get a "server certificate problem" error, for me this seemed to be related to a certificate file in my Firefox profile.

How I came across this was after I rebooted and started Firefox on my 32-bit machine, since my home page is my Google Mail login, Firefox immediately threw a "Could not initialize the browser's security component" error. I found information on that error on Mozilla's site, so on GNU/Linux this means stopping Firefox and deleting the cert8.db file that's in your profile (~/.mozilla/firefox/YOUR_PROFILE.default).

On my 64-bit machine the behavior was slightly different. Everything seemed to work with AnyConnect until I rebooted, at which point it threw the server certificate error. I then launched Firefox and it popped up a completely blank alert window, but when I closed that window and Firefox finished loading, I noticed I couldn't browse to any sites. No matter what I put in the location box the top of the Firefox UI was completely unresponsive.

Since I'd happened to have the security component issue on my 32-bit machine, I figured even though on the 64-bit machine it wasn't actually showing me the error, that might be the problem. Sure enough when I deleted the cert8.db file Firefox then began to work, as did the AnyConnect client. I rebooted to make sure it wasn't a fluke and thus far everything is working.

Remaining Issues

At this point the only remaining issue is that for some reason when I connect to the VPN, AnyConnect doesn't minimize itself into that little "stacked blue balls" icon thingee over near the clock. It just minimizes itself and shows up in your task bar like any other program. Minor annoyance but it does behave correctly on my 32-bit machine so I'm not sure what's going on there.

Hope that helps some others who are trying to get this running!

I have experienced all of the problems you describe above. I have followed all of your directions and still can't connect. Before adding the 32-bit libraries above as you describe I could at least connect to the server, accept the agreements but then would get this warning: "The AnyConnect package on the secure gateway could not be located. You may be experiencing network connectivity issues. Please try connecting again."After putting in the 32-bit libraries I don't even get to the point of entering in my credentials before I get this warnng: "AnyConnect cannot confirm it is connected to your secure gateway. The local network may not be trustworthy. Please try another network."BTW I'm running a new install of Linux Mint 11. Had similar issues on Kubuntu 11.04.Any thoughts?
So this is old, but I run into this problem every now and then.

Why is cisco vpn messing with cert8.db

Thank you very much for your tip about deleting cert8.db.

Now I know what this syslog error means.

Running a Django Application on Windows Server 2012 with IIS

This is a first for me since under normal circumstances we run all our Django applications on Linux with Nginx, but we're in the process of developing an application for another department and due to the requirements around this project, we'll be handing the code off to them to deploy. They don't have any experience with Linux or web servers other than IIS, so I recently took up the challenge of figuring out how to run Django applications on Windows Server 2012 with IIS.

Based on the dated or complete lack of information around this I'm assuming it's not something that's very common in the wild, so I thought I'd share what I came up with in case others need to do this.

Installing and Configuring NextPVR as a Replacement for Windows Media Center

If you follow me on Google+ you'll know I had a recent rant about Windows Media Center, which after running fine for about a year suddenly decided as of January 29 it was done downloading the program guide and by extension was therefore done recording any TV shows.

I'll spare you more ranting and simply say that none of the suggestions I got (which I appreciate!) worked, and rather than spending more time figuring out why, I decided to try something different.

NextPVR is an awesome free (as in beer, not as in freedom unfortunately ...) PVR application for Windows that with a little bit of tweaking handily replaced Windows Media Center. It can even download guide data, which is apparently something WMC no longer feels like doing.

Background I wound up going down this road in a rather circuitous way. My initial goal for the weekend project was to get Raspbmc running on one of my Raspberry Pis. The latest version of XBMC has PVR functionality so I was anxious to try that out as a …

Fixing DPI Scaling Issues in Skype for Business on Windows 10

My setup for my day job these days is a Surface Pro 4 and either an LG 34UC87M-B or a Dell P2715Q monitor, depending on where I'm working. This is a fantastic setup, but some applications have trouble dealing with the high pixel density and don't scale appropriately.
One case in point is Skype for Business. For some reason it scales correctly as I move between the Surface screen and the external monitor when I use the Dell, but on the LG monitor Skype is either massive on the external monitor, or tiny on the Surface screen.
After a big of digging around I came across a solution that worked for me, which is to change a setting in Skype's manifest file (who knew there was one?). On my machine the file is here: C:\Program Files\Microsoft Office\Office16\LYNC.EXE.MANIFEST
And the setting in question is this:
