Hi, starting a while ago I can no longer ssh into my box anymore. I have tried anything I can think of and have no clue anymore. Needless to say that I realy need ssh to access my work from remote places.
Problem: When I ssh -vvv to my server the connection hangs after debug1: expecting SSH2_MSG_KEX_DH_GEX_GROUP System: I'm using Debian with openssh-server (1:4.3p2-8) sshd: OpenSSH_4.3p2 Debian-8, OpenSSL 0.9.8c 05 Sep 2006 uname -a: Linux server 2.6.18-3-686 #1 SMP Mon Dec 4 16:41:14 UTC 2006 i686 GNU/Linux What I tried: I have recompiled a recent openssh from source on the client with now success. (I have no root access on the client and they use an older version of ssh) I have booted grml (grml.org, a live linux cd) on my server and tried to connect to the sshd running from cd in order have a fresh sshd on my server. I have purged and reinstalled openssh-server to get a fresh configuration. I _can_ connect with putty on a windows client. I hope you can help me, and thank you for your consideration. === Client Log === [EMAIL PROTECTED]:~> ssh -vvv [EMAIL PROTECTED] OpenSSH_3.8.1p1 Debian-8.sarge.6, OpenSSL 0.9.7e 25 Oct 2004 debug1: Reading configuration data /etc/ssh/ssh_config debug2: ssh_connect: needpriv 0 debug1: Connecting to server [x.x.x.x] port 22. debug1: Connection established. debug1: read PEM private key done: type DSA debug1: read PEM private key done: type RSA debug1: identity file /home/mw/.ssh/identity type -1 debug1: identity file /home/mw/.ssh/id_rsa type -1 debug1: identity file /home/mw/.ssh/id_dsa type -1 debug1: Remote protocol version 2.0, remote software version OpenSSH_4.3p2 Debian-8 debug1: match: OpenSSH_4.3p2 Debian-8 pat OpenSSH* debug1: Enabling compatibility mode for protocol 2.0 debug1: Local version string SSH-2.0-OpenSSH_3.8.1p1 Debian-8.sarge.6 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,[EMAIL PROTECTED],aes128-ctr,aes192-ctr,aes256-ctr debug2: kex_parse_kexinit: aes128-cbc,3des-cbc,blowfish-cbc,cast128-cbc,arcfour,aes192-cbc,aes256-cbc,[EMAIL PROTECTED],aes128-ctr,aes192-ctr,aes256-ctr 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: kex_parse_kexinit: 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,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,[EMAIL PROTECTED] debug2: kex_parse_kexinit: none,[EMAIL PROTECTED] 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(1024<1024<8192) sent debug1: expecting SSH2_MSG_KEX_DH_GEX_GROUP -- and it hangs here and stays forever === Server Log === server:~# /usr/sbin/sshd -D -d -d -d -e debug2: load_server_config: filename /etc/ssh/sshd_config debug2: load_server_config: done config len = 638 debug2: parse_server_config: config /etc/ssh/sshd_config len 638 debug1: sshd version OpenSSH_4.3p2 Debian-8 debug3: Not a RSA1 key file /etc/ssh/ssh_host_rsa_key. debug1: read PEM private key done: type RSA debug1: private host key: #0 type 1 RSA debug3: Not a RSA1 key file /etc/ssh/ssh_host_dsa_key. debug1: read PEM private key done: type DSA debug1: private host key: #1 type 2 DSA debug1: rexec_argv[0]='/usr/sbin/sshd' debug1: rexec_argv[1]='-D' debug1: rexec_argv[2]='-d' debug1: rexec_argv[3]='-d' debug1: rexec_argv[4]='-d' debug1: rexec_argv[5]='-e' debug2: fd 3 setting O_NONBLOCK debug1: Bind to port 22 on ::.
