Description of problem: Well...SSH connects to HP ILO Management Chips (http://h18004.www1.hp.com/ products/servers/management/ilo/) don't work any longer (and this problem could affect RHEL5 eventually, too): robert@tux:~ > ssh -v Administrator@ilo OpenSSH_4.5p1, OpenSSL 0.9.8b 04 May 2006 debug1: Reading configuration data /etc/ssh/ssh_config debug1: Applying options for * debug1: Connecting to ilo [192.168.0.14] port 22. debug1: Connection established. debug1: identity file /home/robert/.ssh/identity type -1 debug1: identity file /home/robert/.ssh/id_rsa type 1 debug1: identity file /home/robert/.ssh/id_dsa type 2 debug1: Remote protocol version 2.0, remote software version mpSSH_0.0.1 debug1: no match: mpSSH_0.0.1 debug1: Enabling compatibility mode for protocol 2.0 debug1: Local version string SSH-2.0-OpenSSH_4.5 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: sending SSH2_MSG_KEXDH_INIT debug1: expecting SSH2_MSG_KEXDH_REPLY debug1: Host 'ilo' is known and matches the RSA host key. debug1: Found key in /home/robert/.ssh/known_hosts:46 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: password,publickey debug1: Next authentication method: publickey debug1: Trying private key: /home/robert/.ssh/identity debug1: Offering public key: /home/robert/.ssh/id_rsa debug1: Authentications that can continue: password,publickey debug1: Offering public key: /home/robert/.ssh/id_dsa debug1: Authentications that can continue: password,publickey debug1: Next authentication method: password Administrator@ilo's password: debug1: Authentication succeeded (password). debug1: channel 0: new [client-session] debug1: Entering interactive session. debug1: Sending environment. debug1: Sending env LANG = de_DE@euro dispatch_protocol_error: type 100 seq 9 buffer_get_ret: trying to get more bytes 4 than in buffer 0 buffer_get_int: buffer error robert@tux:~ > IMHO the problem came up between openssh-4.3p2-14 and openssh-4.5p1-1, when the SendEnv stuff got enabled, similar or even equivalent to a recent Debian mailing list thread: http://lists.debian.org/debian-ssh/2005/12/msg00025.html Version-Release number of selected component (if applicable): openssh-4.5p1-1 How reproducible & Steps to Reproduce: Everytime, see above. Actual results: Non-working SSH connects. Expected results: Working SSH connects like in the past :) Additional info: If this bug is "notabug" for Red Hat, then HP should be contacted to get this problem solved very soon - finally before RHEL5 is shipping openssh-4.5p1-1 or newer...
