Hi, ii openssh-server 1:5.1p1-5 secure shell server, an rshd replacement
is not able to make revers-portforwarding, at least not the openssh-server of 64bit lenny. lenny 64Bit server: =================== ssh -p 20202 -R *:2235:localhost:22 [email protected] [email protected] is my firewall 192.168.0.11 Client (lenny): =============== rex5:~# ssh -vvv -p 2239 192.168.0.11 OpenSSH_5.1p1 Debian-5, OpenSSL 0.9.8g 19 Oct 2007 debug1: Reading configuration data /etc/ssh/ssh_config debug1: Applying options for * debug2: ssh_connect: needpriv 0 debug1: Connecting to 192.168.0.11 [192.168.0.11] port 2239. debug1: Connection established. debug1: permanently_set_uid: 0/0 debug1: identity file /root/.ssh/identity type -1 debug1: identity file /root/.ssh/id_rsa type -1 debug1: identity file /root/.ssh/id_dsa type -1 ssh_exchange_identification: Connection closed by remote host A machine with lenny32 bit (another customer) is working, revers PFW is possible. The error "ssh_exchange_identification: Connection closed by remote host" appeared there also, but disappeared after some fuzzy troubleshooting. BTW: A Suse8.2 client machine in the same LAN of my customer, Kernel 2.4.18 makes revers PFW without any problem!! So, it must be a problem/ bug/ feature of openssh-server 1:5.1p1-5. The same lenny gust (above) is able to use the revers-PFW: rex5:~# ssh -vvv -p 2235 192.168.0.11 OpenSSH_5.1p1 Debian-5, OpenSSL 0.9.8g 19 Oct 2007 debug1: Reading configuration data /etc/ssh/ssh_config debug1: Applying options for * debug2: ssh_connect: needpriv 0 debug1: Connecting to 192.168.0.11 [192.168.0.11] port 2235. debug1: Connection established. debug1: permanently_set_uid: 0/0 debug1: identity file /root/.ssh/identity type -1 debug1: identity file /root/.ssh/id_rsa type -1 debug1: identity file /root/.ssh/id_dsa type -1 debug1: Remote protocol version 1.99, remote software version OpenSSH_3.5p1 debug1: match: OpenSSH_3.5p1 pat OpenSSH_3.* debug1: Enabling compatibility mode for protocol 2.0 debug1: Local version string SSH-2.0-OpenSSH_5.1p1 Debian-5 debug2: fd 3 setting O_NONBLOCK debug1: SSH2_MSG_KEXINIT sent debug1: SSH2_MSG_KEXINIT received debug2: kex_parse_kexinit: diffie-hellman-group-exchange-sha256,diffie-hellman-group-exchange-sha1,diffie-hellman-group14-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,arcfour128,arcfour256,arcfour,aes192-cbc,aes256-cbc,[email protected],aes128-ctr,aes192-ctr,aes256-ctr debug2: kex_parse_kexinit: aes128-cbc,3des-cbc,blowfish-cbc,cast128-cbc,arcfour128,arcfour256,arcfour,aes192-cbc,aes256-cbc,[email protected],aes128-ctr,aes192-ctr,aes256-ctr debug2: kex_parse_kexinit: hmac-md5,hmac-sha1,[email protected],hmac-ripemd160,[email protected],hmac-sha1-96,hmac-md5-96 debug2: kex_parse_kexinit: hmac-md5,hmac-sha1,[email protected],hmac-ripemd160,[email protected],hmac-sha1-96,hmac-md5-96 debug2: kex_parse_kexinit: none,[email protected],zlib debug2: kex_parse_kexinit: none,[email protected],zlib 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,[email protected] debug2: kex_parse_kexinit: aes128-cbc,3des-cbc,blowfish-cbc,cast128-cbc,arcfour,aes192-cbc,aes256-cbc,[email protected] debug2: kex_parse_kexinit: hmac-md5,hmac-sha1,hmac-ripemd160,[email protected],hmac-sha1-96,hmac-md5-96 debug2: kex_parse_kexinit: hmac-md5,hmac-sha1,hmac-ripemd160,[email protected],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_setup: found hmac-md5 debug1: kex: server->client aes128-cbc hmac-md5 none debug2: mac_setup: found hmac-md5 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 debug2: dh_gen_key: priv key bits set: 125/256 debug2: bits set: 499/1024 debug1: SSH2_MSG_KEX_DH_GEX_INIT sent debug1: expecting SSH2_MSG_KEX_DH_GEX_REPLY debug3: put_host_port: [192.168.0.11]:2235 debug3: put_host_port: [192.168.0.11]:2235 debug3: check_host_in_hostfile: filename /root/.ssh/known_hosts debug3: check_host_in_hostfile: filename /etc/ssh/ssh_known_hosts debug3: check_host_in_hostfile: filename /root/.ssh/known_hosts debug3: check_host_in_hostfile: filename /etc/ssh/ssh_known_hosts debug1: checking without port identifier debug3: check_host_in_hostfile: filename /root/.ssh/known_hosts debug3: check_host_in_hostfile: filename /etc/ssh/ssh_known_hosts debug3: check_host_in_hostfile: filename /root/.ssh/known_hosts debug3: check_host_in_hostfile: filename /etc/ssh/ssh_known_hosts debug2: no key of type 0 for host [192.168.0.11]:2235 debug3: check_host_in_hostfile: filename /root/.ssh/known_hosts2 debug3: check_host_in_hostfile: filename /etc/ssh/ssh_known_hosts2 debug3: check_host_in_hostfile: filename /root/.ssh/known_hosts debug3: check_host_in_hostfile: filename /etc/ssh/ssh_known_hosts debug2: no key of type 2 for host [192.168.0.11]:2235 The authenticity of host '[192.168.0.11]:2235 ([192.168.0.11]:2235)' can't be established.
