Symptoms:

The following behavior has been noticed only by linux users who are also running CSD HostScan:

Cause / Problem Description

In the libcsd.log file you'll see:

-------------------------------------------------8<----------------------------------------------

--------------------------------------------------8<---------------------------------------------

This is because the CSD HostScan code signing certificate expired yesterday. Mac and Windows users are not affected as the client code only checks if the certificate was valid when the code was signed. However, the Linux code checks on the current validity of the certificate.

Resolution:

The behavior on Linux will be changed as soon as posisble to mirror the treatment on MAC and Windows. While we don't recommend changing the system clock as a matter of course, for the time being the only way around it is to reset the linux system clock to something before Feb 7th, 2013. Please see bug CSCue49663 for addition details.

Important UPDATE: This bug is now fixed in AC 3.1.2043.

Your ASA should be configured as follows:
webvpn
enable outside
csd hostscan image disk0:/hostscan_3.1.02043-k9.pkg
csd enable
anyconnect image disk0:/anyconnect-win-3.1.02040-k9.pkg 1 regex "Windows NT"
anyconnect image disk0:/anyconnect-macosx-i386-3.1.02040-k9.pkg 2 regex "Mac OS"
anyconnect image disk0:/anyconnect-linux-3.1.02043-k9.pkg* 3 regex "Linux"

I am not privileged to view CSCue49663. Does Cisco have an ETA when either the client will be updated or the certificates renewed?

Darin, I've updated the bug. You should be able to view it now without any errors. Apart from that we are hoping to have a fix ready for this by tomorrow or latest by the end of this week.

Posture Assessment problem still persists in 3.1.02043.  When we downloaded 3.1.02043 yesterday afternoon, the package still had the original version of the CSD, Is this correct?

I also downloaded and installed 3.1.02043 and the problem is still present for me as well.

Are all of you using the Anyconnect package for the hostscan?

Atri, Yes I am using the Anyconnect client (/opt/cisco/anyconnect/bin/vpnui). Same result occurs whether I use vpnui or the vpn terminal version.

Atri, Yes I am also using the Anyconnect client (/opt/cisco/anyconnect/bin/vpnui).

Folks, I have customers who've reported that the AC client resolved their issue. So just to confirm do all of you have the following configuration in place:

webvpn

enable outside

csd hostscan image disk0:/anyconnect-win-3.1.02026-k9.pkg

csd enable

anyconnect image disk0:/anyconnect-win-3.1.02026-k9.pkg 1

anyconnect image disk0:/anyconnect-macosx-i386-3.1.02026-k9.pkg 2

anyconnect image disk0:/anyconnect-linux-3.1.02026-k9.pkg 3

anyconnect enable

You don't necessarily need to add all the OS versions of anyconnect but note the CSD hostscan image being used is the anyconnect image.

I have the linux image anyconnect-predeploy-linux-3.1.02043-k9.tar.gz installed.

Still have the issues with the following images on the ASA:

webvpn

enable outside

csd hostscan image disk0:/anyconnect-win-3.1.02040-k9.pkg

csd enable

anyconnect image disk0:/anyconnect-win-3.1.02040-k9.pkg 1 regex "Windows NT"

anyconnect image disk0:/anyconnect-macosx-i386-3.1.02040-k9.pkg 2 regex "Mac OS"

anyconnect image disk0:/anyconnect-linux-3.1.02043-k9.pkg 3 regex "Linux"

I have updated this doc with the configuration that should work. Can all of you please try that and let me know if it resolves your issues?

weslanhenry

Atri,

Will there be any updated "Predeploy" packages (I.e anyconnect-predeploy-linux-3.1.02043-k9.tar.gz)

that will work for linux, as I don't have access to the ASA server?

I have confirmed that this combination appears to work with using the hostscan image for CSD...

webvpn

enable outside

csd hostscan image disk0:/hostscan_3.1.02043-k9.pkg

csd enable

anyconnect image disk0:/anyconnect-win-3.1.02040-k9.pkg 1 regex "Windows NT"

anyconnect image disk0:/anyconnect-macosx-i386-3.1.02040-k9.pkg 2 regex "Mac OS"

anyconnect image disk0:/anyconnect-linux-3.1.02043-k9.pkg 3 regex "Linux"

I am however, still regression testing other clients (Windows, MacOSX).

I'm also seeing this problem using anyconnect-win-3.1.02040-k9.pkg.
