Check /etc/hosts.deny and /etc/hosts.allow Many have reported configuring these to values properly has helped. However, we've seen this issue even when hosts.* files were not a factor. root@host # grep sshd /etc/hosts.allow sshd:

ALL Missing Dependencies This one typically happens after a glibc or openssl upgrade. Many distros can install updates to glibc or openssl libs and not require a restart to sshd. On any distro you can recognize it when after an update, then use lsof to see where sshd has open files. Some will be pointed to DEL, because those libs were deleted on update. ~ # lsof -n | grep ssh | grep DEL When an SSH connection comes in the sshd daemon forks and attempts to attach (ld) these lib files, and fails resulting in this error. Corrupted Fingerprint / Keys Some how one or the other of the fingerprints or keys has become corrupted (did you manually edit one of these files?). Remove the server-side fingerprint in the clients ~/.ssh/known_hosts and try again. When you re-connect you will be prompted to accept the host identity again. If you are able to access the machine another way you may want to back-out and re-create the

and you will see many similar posts. ssh_exchange_identification: http://edoceo.com/notabene/ssh-exchange-identification is one I can see but there may be others that are in your own language to help Regarding how to http://edoceo.com/notabene/ssh-exchange-identification use workbench, it would be a matter of configuring workbench.

You can see what your Codio key is by runningcat ~/.ssh/authorized_keys in the terminal but also review how you have your 'workbench' set up, perhaps some firewall you are using is involved ? sebabarr 2014-09-22 13:16:26 UTC #5 thanks.!I put the command in the terminal and i can see the rsa_key , its seem ok. when i try to connect i get this.sebastian@sebastian-TA75M:~$ sudo ssh -v codio@ssh2.codio.com -p 4825 OpenSSH_6.6.1, OpenSSL 1.0.1f 6 Jan 2014debug1: Reading configuration data /etc/ssh/ssh_configdebug1: /etc/ssh/ssh_config line 19: Applying options for *debug1: Connecting to ssh2.codio.com [54.81.42.31] port 4825.debug1: Connection established.debug1: permanently_set_uid: 0/0debug1: identity file /root/.ssh/id_rsa type 1debug1: identity file /root/.ssh/id_rsa-cert type -1debug1: identity file /root/.ssh/id_dsa type -1debug1: identity file /root/.ssh/id_dsa-cert type -1debug1: identity file /root/.ssh/id_ecdsa type -1debug1: identity file /root/.ssh/id_ecdsa-cert type -1debug1: identity file /root/.ssh/id_ed25519 type -1debug1: identity file /root/.ssh/id_ed25519-cert type -1debug1: Enabling compatibility mode for protocol 2.0debug1: Lo

It was failing intermittently with the error below: ssh_exchange_identification: Connection closed by remote host We all know that it's a generic one.

Is this due to any DDOS attack on SSH server which has already made so many connections? Or is this is due to Max_Connection limit on SSH server ? (But Max_Connects works on per network basis we tried from 3 different networks and got the same error) Or is there a possible chance of number of currently opened files
