I am having a problem in using ssh in UML. My host can ssh into the uml but ssh from uml into host fails. following is what happens: ************* FROM UML TO HOST ******************* bash-2.05# ssh -v -l root 130.126.141.70 OpenSSH_3.1p1, SSH protocols 1.5/2.0, OpenSSL 0x0090602f debug1: Reading configuration data /etc/ssh/ssh_config debug1: Applying options for * debug1: Rhosts Authentication disabled, originating port will not be trusted. debug1: restore_uid debug1: ssh_connect: getuid 0 geteuid 0 anon 1 debug1: Connecting to 130.126.141.70 [130.126.141.70] port 22. debug1: temporarily_use_uid: 0/0 (e=0) debug1: restore_uid debug1: temporarily_use_uid: 0/0 (e=0) debug1: restore_uid debug1: Connection established. debug1: read PEM private key done: type DSA debug1: read PEM private key done: type RSA debug1: identity file /root/.ssh/id_rsa type -1 debug1: identity file /root/.ssh/id_dsa type -1 debug1: Remote protocol version 2.0, remote software version OpenSSH_4.7p1 Debian-8ubuntu1.2 debug1: match: OpenSSH_4.7p1 Debian-8ubuntu1.2 pat OpenSSH* Enabling compatibility mode for protocol 2.0 debug1: Local version string SSH-2.0-OpenSSH_3.1p1 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 sent debug1: expecting SSH2_MSG_KEX_DH_GEX_GROUP debug1: dh_gen_key: priv key bits set: 136/256 debug1: bits set: 999/2048 debug1: SSH2_MSG_KEX_DH_GEX_INIT sent debug1: expecting SSH2_MSG_KEX_DH_GEX_REPLY Host key verification failed. debug1: Calling cleanup 0x8063550(0x0) *********************FROM HOST TO UML *************************** root@vanilla:/home/vanilla# ssh -v -l 192.168.0.253 OpenSSH_4.7p1 Debian-8ubuntu1.2, OpenSSL 0.9.8g 19 Oct 2007 usage: ssh [-1246AaCfgKkMNnqsTtVvXxY] [-b bind_address] [-c cipher_spec] [-D [bind_address:]port] [-e escape_char] [-F configfile] [-i identity_file] [-L [bind_address:]port:host:hostport] [-l login_name] [-m mac_spec] [-O ctl_cmd] [-o option] [-p port] [-R [bind_address:]port:host:hostport] [-S ctl_path] [-w local_tun[:remote_tun]] [user@]hostname [command] root@vanilla:/home/vanilla# ssh -v -l root 192.168.0.253 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 192.168.0.253 [192.168.0.253] port 22. debug1: Connection established. debug1: permanently_set_uid: 0/0 debug1: identity file /root/.ssh/id_rsa type -1 debug1: identity file /root/.ssh/id_dsa type -1 debug1: Remote protocol version 2.0, remote software version OpenSSH_3.1p1 debug1: match: OpenSSH_3.1p1 pat OpenSSH_2.*,OpenSSH_3.0*,OpenSSH_3.1* 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(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 '192.168.0.253' is known and matches the RSA host key. debug1: Found key in /root/.ssh/known_hosts:3 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,password,keyboard-interactive debug1: Next authentication method: publickey debug1: Trying private key: /root/.ssh/id_rsa debug1: Trying private key: /root/.ssh/id_dsa debug1: Next authentication method: keyboard-interactive debug1: Authentications that can continue: publickey,password,keyboard-interactive debug1: Next authentication method: password root@192.168.0.253's password: debug1: Authentication succeeded (password). debug1: channel 0: new [client-session] debug1: Entering interactive session.

It's a combination of a certain version of the kernel (UML & host) and the skas 4 patch and UML. What i saw was that ssh couldn't get started because it couldn't get enough random bytes. That might be the same in your case. Look at the thread titled "ssh can't obtain random bytes" In Debian, when i checked /var/log/auth.log i found these messages: sshd[1712]: fatal: Couldn't obtain random bytes (error 604389476) See if you can find similar messages in the logs. I couldn't get i working but i thought Jeff said (i could be wrong) that it was solved in one of the later version of the kernel already. Regards, Benedict |

This is a different problem, and I believe it's fixed in 2.6.26. Jeff -- Work email - jdike at linux dot intel dot com |
