Is this only occurring during debug sessions? -T -----Original Message----- From: listbounce@xxxxxxxxxxxxxxxxx [mailto:listbounce@xxxxxxxxxxxxxxxxx] On Behalf Of Kosala Atapattu Sent: Saturday, July 24, 2010 11:57 PM To: secureshell@xxxxxxxxxxxxxxxxx Subject: ssh hangs after SSH2_MSG_SERVICE_ACCEPT Hi All, My servers suddenly started giving problem across all the machines. When I try to connect, the ssh debug output stops near the SSH2_MSG_SERVICE_ACCEPT and then continues after a minute or so. root@s2spr1[/home/root] #ssh -v t1was1_nim OpenSSH_5.2p1, OpenSSL 0.9.8k 25 Mar 2009 debug1: Reading configuration data /etc/ssh/ssh_config debug1: Failed dlopen: /usr/krb5/lib/libkrb5.a(libkrb5.a.so): 0509-022 Cannot load module /usr/krb5/lib/libkrb5.a(libkrb5.a.so). 0509-026 System error: A file or directory in the path name does not exist. debug1: Error loading Kerberos, disabling Kerberos auth. debug1: Connecting to t1was1_nim [10.1.1.114] port 22. debug1: Connection established. debug1: permanently_set_uid: 0/0 debug1: identity file /home/root/.ssh/identity type -1 debug1: identity file /home/root/.ssh/id_rsa type -1 debug1: identity file /home/root/.ssh/id_dsa type 2 debug1: Remote protocol version 2.0, remote software version OpenSSH_5.2 debug1: match: OpenSSH_5.2 pat OpenSSH* debug1: Enabling compatibility mode for protocol 2.0 debug1: Local version string SSH-2.0-OpenSSH_5.2 debug1: SSH2_MSG_KEXINIT sent debug1: SSH2_MSG_KEXINIT received debug1: kex: server->client aes128-ctr hmac-md5 none debug1: kex: client->server aes128-ctr 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 't1was1_nim' is known and matches the RSA host key. debug1: Found key in /home/root/.ssh/known_hosts:79 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 I have not changed anything in these machines. This is just a sudden move.
