Public bug reported: Binary package hint: openssh-client
ssh X11 forwarding to my intrepid client from my openssh server used to work, but it always fails now, with "Invalid MIT-MAGIC-COOKIE". Please see the example session log below. Forwarding succeeds to a Windows client running PuTTY, so the problem isn't with the server, so I conclude that it's with the client. I'd be glad to provide further information or troubleshooting. Thanks, Andrew. $ lsb_release -rd Description: Ubuntu 8.10 Release: 8.10 $ apt-cache policy openssh-client openssh-client: Installed: 1:5.1p1-3ubuntu1 Candidate: 1:5.1p1-3ubuntu1 Version table: *** 1:5.1p1-3ubuntu1 0 500 http://us.archive.ubuntu.com intrepid/main Packages 100 /var/lib/dpkg/status $ ssh -v -X -l andrex 5200-glenwood.net kate OpenSSH_5.1p1 Debian-3ubuntu1, OpenSSL 0.9.8g 19 Oct 2007 debug1: Reading configuration data /etc/ssh/ssh_config debug1: Applying options for * debug1: Connecting to 5200-glenwood.net [68.55.218.17] port 22. debug1: Connection established. debug1: identity file /home/carey/.ssh/identity type -1 debug1: identity file /home/carey/.ssh/id_rsa type -1 debug1: identity file /home/carey/.ssh/id_dsa type -1 debug1: Remote protocol version 2.0, remote software version OpenSSH_5.1p1 Debian-5 debug1: match: OpenSSH_5.1p1 Debian-5 pat OpenSSH* debug1: Enabling compatibility mode for protocol 2.0 debug1: Local version string SSH-2.0-OpenSSH_5.1p1 Debian-3ubuntu1 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(1024<1024<8192) 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 '5200-glenwood.net' is known and matches the RSA host key. debug1: Found key in /home/carey/.ssh/known_hosts:1 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 debug1: Next authentication method: publickey debug1: Offering public key: Public Key debug1: Server accepts key: pkalg ssh-rsa blen 277 debug1: Authentication succeeded (publickey). debug1: channel 0: new [client-session] debug1: Requesting no-more-sessi...@openssh.com debug1: Entering interactive session. debug1: No xauth program.
