Hello, I am testing ssh with occasional network disconnection between server and client during these days. I found ssh sometimes hangs if the disconnection happens after the connection is established but before ssh_exchange_identification completes. The ssh configuration files show that both client and server alive options are set. In /etc/ssh/ssh_config: # Send keepalive messages to the server. Disconnect after 90 seconds. ServerAliveInterval 30 ServerAliveCountMax 3 In /etc/ssh/sshd_config: # ClientAlive is more flexibl...

Hi, I'm getting this error when I ssh to the servers. ssh_exchange_identification: Connection closed by remote host I added /etc/hosts.allow and it actually worked once and if I tried again I get the same error.

...connect without problems via SSH to both servers from my home Fedora 16 desktop. Yesterday I completed (fingers crossed) the switch to a different ADSL provider. From the moment I turned on the modem on the new ADSL line, I became unable to ssh into server A. All attempts abort with this message: ssh_exchange_identification: Connection closed by remote host I know that server A is still up and running, because the websites and email services it runs are still up. Server B is still reachable via ssh, no problem. The only difference between the two servers is that A runs Centos 4.something, while B runs Centos 6...

Guys, I think that I have ran into a bug. I am running openbsd 2.8 and I upgraded to the lastest verison of openssh 2.9 but when I did that it started giving me this error "ssh_exchange_identification: Connection closed by remote host" when I try to log into the machine even when I am on the machine and try to ssh localhost it gives me the same message. I have read every FAQ I could find on the net but all I can find is that you mush put "ssd:all" in the hosts.allow in the...

I'm randomly getting the following error on a server from various remote hosts: ssh_exchange_identification: Connection closed by remote host The server is running OpenSSH 4.5p1 w/GSSAPI Key Exchange patch. The hosts connecting to it should all be using OpenSSH 5.0p1 w/GSSAPI Key Exchange patch and using gssapi-keyex authentication. Normally, when I've seen this error, it means access to...

...scp files to a set of receiving servers. There are about 25 sending machines, and 12 receiving machines. All the servers are RHEL 4 and 5, with the senders running openssh 4.3p2, and the receivers running 3.9p1. Most files are sent without a problem, but on a pretty regular basis, we get "ssh_exchange_identification: Connection closed by remote host" in our log files on the senders. The odd/interesting thing is that while that error often shows up on a connection to one machine, we also get bursts, where the error happens on connections to several different machines at once. That leads us to thi...

The strange thing is that sometimes the error message is different, (not less confusing, unfortunately) This is the error message I've been getting: -> ssh_exchange_identification: read: Success I have also got it to give me these error messages: -> ssh_exchange_identification: read: Address already in use -> ssh_exchange_identification: read: File not found (something to that effect) It looks like the sshd on the server I am connecting to is not sending anyth...
