Problem with openconnect after upgrade to ubuntu 18.04

  • 772

After upgrading to 18.04 I can't use openconnect anymore. Here is the issue:

Established DTLS connection (using GnuTLS). Ciphersuite (DTLS1.2)-(PSK)-(AES-256-GCM).  
DTLS connection compression using LZ4.  
Failed to read from SSL socket: The transmitted packet is too large (EMSGSIZE).  
Failed to recv DPD request (1434)

I have no idea what it means. Any suggestion?

networking upgrade 18.04 openconnect

  1. I have the same problem. Try one of the below:

    • run the command with --no-dtls option
    • try openconnect version 7.06-2 (not available in ubuntu 18.04)
    • try using the cisco anyconnect client binaries instead of openconnect

    If anyone has a solution for this problem, I'm also interested to know
