Hi, Since I installed 1 of my server afresh, I'm getting this problem while trying to SSH to the remote machine from within a script. Same script was working fine earlier. I can SSH from the prompt but from within the script it gives this error: Host key authentication failure if I use -vvv with SSH comand (for debug essages), the output is: 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 48 geteuid 0 anon 1 debug1: Connecting to HOST [IP] port 22. debug1: temporarily_use_uid: 48/48 (e=0) debug1: restore_uid debug1: temporarily_use_uid: 48/48 (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 /var/www/.ssh/identity type -1 debug1: identity file /var/www/.ssh/id_rsa type -1 debug1: identity file /var/www/.ssh/id_dsa type -1 debug1: Remote protocol version 1.99, remote software version OpenSSH_2.9p2 debug1: match: OpenSSH_2.9p2 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 debug2: kex_parse_kexinit: diffie-hellman-group-exchange-sha1,diffie-hellman-group1-sha1 debug2: kex_parse_kexinit: ssh-rsa,ssh-dss debug2: kex_parse_kexinit: aes128-cbc,3des-cbc,blowfish-cbc,cast128-cbc,arcfour,aes192-cbc,aes256-cbc debug2: kex_parse_kexinit: aes128-cbc,3des-cbc,blowfish-cbc,cast128-cbc,arcfour,aes192-cbc,aes256-cbc debug2: kex_parse_kexinit: hmac-md5,hmac-sha1,hmac-ripemd160,hmac-ripemd160@xxxxxxxxxxx,hmac-sha1-96,hmac-md5-96 debug2: kex_parse_kexinit: hmac-md5,hmac-sha1,hmac-ripemd160,hmac-ripemd160@xxxxxxxxxxx,hmac-sha1-96,hmac-md5-96 debug2: kex_parse_kexinit: none debug2: kex_parse_kexinit: none debug2: kex_parse_kexinit: debug2: kex_parse_kexinit: debug2: kex_parse_kexinit: first_kex_follows 0 debug2: kex_parse_kexinit: reserved 0 debug2: kex_parse_kexinit: diffie-hellman-group-exchange-sha1,diffie-hellman-group1-sha1 debug2: kex_parse_kexinit: ssh-rsa,ssh-dss debug2: kex_parse_kexinit: aes128-cbc,3des-cbc,blowfish-cbc,cast128-cbc,arcfour,aes192-cbc,aes256-cbc,rijndael128-cbc,rijndael192-cbc,rijndael256-cbc,rijndael-cbc@xxxxxxxxxxxxxx debug2: kex_parse_kexinit: aes128-cbc,3des-cbc,blowfish-cbc,cast128-cbc,arcfour,aes192-cbc,aes256-cbc,rijndael128-cbc,rijndael192-cbc,rijndael256-cbc,rijndael-cbc@xxxxxxxxxxxxxx debug2: kex_parse_kexinit: hmac-md5,hmac-sha1,hmac-ripemd160,hmac-ripemd160@xxxxxxxxxxx,hmac-sha1-96,hmac-md5-96 debug2: kex_parse_kexinit: hmac-md5,hmac-sha1,hmac-ripemd160,hmac-ripemd160@xxxxxxxxxxx,hmac-sha1-96,hmac-md5-96 debug2: kex_parse_kexinit: none,zlib debug2: kex_parse_kexinit: none,zlib debug2: kex_parse_kexinit: debug2: kex_parse_kexinit: debug2: kex_parse_kexinit: first_kex_follows 0 debug2: kex_parse_kexinit: reserved 0 debug2: mac_init: found hmac-md5 debug1: kex: server->client aes128-cbc hmac-md5 none debug2: mac_init: found hmac-md5 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: 131/256 debug1: bits set: 990/2049 debug1: SSH2_MSG_KEX_DH_GEX_INIT sent debug1: expecting SSH2_MSG_KEX_DH_GEX_REPLY debug3: check_host_in_hostfile: filename /var/www/.ssh/known_hosts debug3: check_host_in_hostfile: filename /etc/ssh/ssh_known_hosts debug3: check_host_in_hostfile: filename /var/www/.ssh/known_hosts debug3: check_host_in_hostfile: filename /etc/ssh/ssh_known_hosts Host key verification failed. debug1: Calling cleanup 0x8063510(0x0) Any suggestions....
