acwebsecagent: Connection : Auth key is not provided, bypassing towers. CMode : 2 TMode : 0

Same here. This is making my console logs unreadable. Annoying. What is it doing by the way? Shouldn’t be trying to authenticate itself somewhere while I don't use it…

I believe this is related to Cisco anyconnect software. It was preventing other stuff I have from running properly so I uninstalled it and the errors went away.

Did you mean:

sudo /opt/cisco/anyconnect/bin/websecurity_uninstall.sh

I found that looking in that bin directory. It removed just the offending program, which my company did not seem to be using. And now my console log is much quieter.

Riidiculous that the agent was running when there was no VPN running or connection established.

Seems like the web security agent was somehow removed previously for you.

"acvpnagent" is definitely another part of Cisco AnyConnect VPN, but I don't think the message is directly related.

Not much to go on, but from the messages above, it seems you might have only a partially installed AnyConnect client now. Have you done a Mountain Lion ugprade since your original post? If so, that might have removed some of the pieces of AnyConnect. Pure conjecture on my part though.

Regardless, your console is quiet which is all I was seeking.

Wow, a big "me too" here. I was having a ton of problems with peformance in Chrome that made it look like my Internet had died, but pings and other tests would work perfectly. I'd switch the Safari and it would sometimes kinda work, othertime not.

I ran the websecurity_unistall.sh script and the errors have gone away, and SO FAR my browsers are working perfectly.

As a side rant, why would this even be installed by default in the first place? This seems like an opt-in / admin installation thing if you have a license that supports it, not something that sits in the critical path of your web requests only to fail a license test and sometimes get stuck. AND way too much use of 'cloud' in one sentence for security software 🙂..

A little follow up: It has been over a month and a half since making this change and it is clear that this was the issue.

Cisco even acknowledged the bug and should have a fix soon.

From their Twitter account:

Bug ID: CSCuc16357. Should be available in 3.0 and 3.1 releases in November.

Had the exact same problem - did a "default" AnyConnect install a few weeks back for one of my jobs, found out I wouldn't actually need to use it until January, so I just left it there. Shortly thereafter, noticed horrible performance in web browsers, especially if I was trying to open several pages at once. (Well, yes, something that's trying to screen all the web content would cause that.) FINALLY decided to look at my logs after checking various other things, and bam, acwebsecagent all over the place. Thanks to Spencer and Matt, I uninstalled, reinstalled JUST the parts I actually needed, and am a happy camper again.

I had problems with my Mac where the Internet would just stop working in OS X 10.8.4 - after finding this article I installed Little Snitch and found that the acwebsecagent VPN client responsible for the problems. Despite the fact that I was not logged into the VPN this software was actively routing all my Internet access through it's process, which must have been terribly inefficient because as noted my Internet would just stop working.

The command mentioed above

sudo /opt/cisco/anyconnect/bin/websecurity_uninstall.sh

Fixed my problem of being able to connect to a subversion server. Once the Web security module was removed, then it connected right away. Thanks

Thanks! I've been living with this for two years. Now my Chrome doesn't take so friggin' long to start up and my console isn't clogged with error messages.
