Anyconnect cscan failure on Fedora 32

I’ve been fighting with Fedora 32 for some time, trying to get Cisco Anyconnect client working. It was working on Fedora 31, and I have it working on CentOS 8, but for some reason Fedora 32 on new install will not work for me.

My work uses secondary authentication after user/pass, but I can’t get past the initial login. The initial scan when choosing a vpn end point is failing during posture assessment and update. When that fails, it goes to login, I enter user/pass and nothing else happens.

I did find what appears to be an issue with cscan failing, but no idea how/why and would really appreciate some assistance in troubleshooting. What I pulled from journalctl for cscan follows, but basically it fails for some reason and tries to generate a core dump but can’t (not sure why not).

If there is anything else I can provide or questions I can answer, I’ll do my best. I’m really at a loss at this point and this is the one show stopper for me using Fedora.

Should be able to generate a dump given these limits, right?

Welcome to the community @ek01! Please take a minute to go through the informative posts in the #start-here if you’ve not had a chance yet. They include information on how the forum works and so on.

Is selinux enabled? Perhaps try with sudo setenforce 0 just to be sure that it isn’t an selinux issue?

Work here also uses Anyconnect. I got it working with network manager by using the csd-post.sh script provided by openconnect. Maybe that’s worth a try too?

The path to the csd-post.sh script is: /usr/libexec/openconnect/csd-post.sh. I don’t think the OS needs to be set there, but I just threw it in anyway :laughing:

(This doesn’t require one to be root or anything at all)

Thanks for the reply. I tried disabling the firewall as well as selinux as a test previously with no success. I had not tried Network manager, but I was able to get connected with that. I’m removing anyconnect now.

I hadn’t thought to try that because of the token and just assuming I had to use Cisco. I would have hit a wall with the script reference either way, so much appreciation for that.

The only other question I have is why I wasn’t seeing the core dump files for cscan? I don’t know if you can answer that, or if that’s a question for a different thread but I would like to understand that bit as well.

Thanks for the quick reply and solution.
