Connecting to such servers from Ubuntu introduces an extensive delay that you don't get if you connect to such servers directly from a CentOS box. The problem is triggered by the delay on reverse lookups that aren't answered due to the avahi configuration of Ubuntu desktops. ** Summary changed: - ssh -v reports debug1 - unspecified gss failure. minor code may provide more information + ssh client pauses during GSS negotiation due to delay on reverse lookup in avahi -- ssh client pauses during GSS negotiation due to delay on reverse lookup in avahi https://bugs.launchpad.net/bugs/416264 You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to openssh in ubuntu. -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs

Excuse me Chuck but the problem is clear. When you do ssh -v SERVER.DOMAIN you obtain an output similar to the following: OpenSSH_4.7p1 Debian-8ubuntu1.2, OpenSSL 0.9.8g 19 Oct 2007 debug1: Reading configuration data /etc/ssh/ssh_config debug1: Applying options for * debug1: Connecting to wall [141.250.199.62] port 22. debug1: Connection established. debug1: identity file /home/marcop/.ssh/identity type -1 debug1: identity file /home/marcop/.ssh/id_rsa type -1 debug1: identity file /home/marcop/.ssh/id_dsa type -1 debug1: Remote protocol version 2.0, remote software version OpenSSH_3.9p1 debug1: match: OpenSSH_3.9p1 pat OpenSSH_3.* debug1: Enabling compatibility mode for protocol 2.0 debug1: Local version string SSH-2.0-OpenSSH_4.7p1 Debian-8ubuntu1.2 debug1: SSH2_MSG_KEXINIT sent debug1: SSH2_MSG_KEXINIT received debug1: kex: server-client aes128-cbc hmac-md5 none debug1: kex: client-server aes128-cbc hmac-md5 none debug1: SSH2_MSG_KEX_DH_GEX_REQUEST(102410248192) sent debug1: expecting SSH2_MSG_KEX_DH_GEX_GROUP debug1: SSH2_MSG_KEX_DH_GEX_INIT sent debug1: expecting SSH2_MSG_KEX_DH_GEX_REPLY debug1: Host 'wall' is known and matches the RSA host key. debug1: Found key in /home/marcop/.ssh/known_hosts:87 debug1: ssh_rsa_verify: signature correct debug1: SSH2_MSG_NEWKEYS sent debug1: expecting SSH2_MSG_NEWKEYS debug1: SSH2_MSG_NEWKEYS received debug1: SSH2_MSG_SERVICE_REQUEST sent debug1: SSH2_MSG_SERVICE_ACCEPT received debug1: Authentications that can continue: publickey,gssapi-with-mic,password debug1: Next authentication method: gssapi-with-mic debug1: Unspecified GSS failure.

I don't know what Unspecified GSS failure means. I have no kerberos system installed in my network (maybe could be this?). However my problem was related to the fact that connecting to a server via ssh, apart from displaying the error indicated above (GSS failure), it took to long. I found that the problem was related to the fact that GSSAPIAuthentication was on by default on ssh server and the server had no reverse dns IP (it has a private address). Disabling GSSAPIAuthentication fixed the issue for me. I obtain the same error (GSS failure) also connecting to other server that have correct DNS config and GSSAPIAuthentication enabled but in these servers I don't realize about the error because of there is no delay in the connection (thanks to right DNS direct and reverse loookup). I say again that I don't know GSSAPI so if the error could be related to the fact that I have no kerberos system we could mark the bug as invalid or similar. -- ssh -v reports debug1 - unspecified gss failure. minor code may provide more information https://bugs.launchpad.net/bugs/416264 You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to openssh in ubuntu. -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs

Thank you for taking the time to report this bug and helping to make Ubuntu better. Unfortunately, we can't fix it because your description didn't include enough information. You may find it helpful to read How to report bugs effectively http://www.chiark.greenend.org.uk/~sgtatham/bugs.html. We'd be grateful if you would then provide a more complete description of the problem. We have instructions on debugging some types of problems at http://wiki.ubuntu.com/DebuggingProcedures. At a minimum, we need: 1. the specific steps or actions you took that caused you to encounter the problem, 2. the behavior you expected, and 3. the behavior you actually encountered (in as much detail as possible). Thanks! When reporting bugs in the future please use apport, either via the appropriate application's Help - Report a Problem menu or using 'ubuntu-bug' and the name of the package affected. You can learn more about this functionality at https://wiki.ubuntu.com/ReportingBugs. ** Changed in: openssh (Ubuntu) Importance: Undecided = Low ** Changed in: openssh (Ubuntu) Status: New = Incomplete -- ssh -v reports debug1 - unspecified gss failure. minor code may provide more information https://bugs.launchpad.net/bugs/416264 You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to openssh in ubuntu. -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
