ssh_exchange_identification: Connection closed by

Question

I work at win7 and set up git server with sshd. I git --bare init myapp.git, and clone ssh://git@localhost/home/git/myapp.git in Cywgin correctly. But I need config git of Cygwin again, I want to git clone in Git Bash. I run git clone ssh://git@localhost/home/git/myapp.git and get following message

ssh_exchange_identification: Connection closed by remote host

then I run ssh -vvv git@localhost in Git Bash and get message

debug2: ssh_connect: needpriv 0
debug1: Connecting to localhost [127.0.0.1] port 22.
debug1: Connection established.
debug1: identity file /c/Users/MoreFreeze/.ssh/identity type -1
debug3: Not a RSA1 key file /c/Users/MoreFreeze/.ssh/id_rsa.
debug2: key_type_from_name: unknown key type '-----BEGIN'
debug3: key_read: missing keytype
debug3: key_read: missing whitespace 
// above it repeats 24 times
debug2: key_type_from_name: unknown key type '-----END'
debug3: key_read: missing keytype
debug1: identity file /c/Users/MoreFreeze/.ssh/id_rsa type 1
debug1: identity file /c/Users/MoreFreeze/.ssh/id_dsa type -1
ssh_exchange_identification: Connection closed by remote host

it seems my private keys has wrong format? And I find that there are exactly 25 line in private keys without BEGIN and END. I'm confused why it said NOT RSA1 key, I totally ensure it is RSA 2 key.

Any advises are welcome. btw, I have read first 3 pages on google about this problem.

Answer 1

Please use Port 7999 and Try. it will work

Answer 2

if hostname does not work, try IP address.

This is going on right now so I have to say. I try to ssh with my host name and it does not work

ssh [e-mail]

this gives the error "ssh_exchange_identification: Connection closed by remote host"

this USED to work one hour back.

BUT, and here is the interesting part, the IP address works!

ssh root@192.168.0.100

(of course the actual IP address is different)

Go figure!

Answer 3

For me this was caused by a limit on the number of concurrent ssh sessions. I added the two params below to /etc/ssh/sshd_config and then things worked.

echo 'MaxSessions 2000' >> /etc/ssh/sshd_config
echo 'MaxStartups 2000' >> /etc/ssh/sshd_config
service ssh restart

Hi I fix this on one vps service, restarting it, other way is if you have a console from your service o any other way to run a command in your remote machine the only command you must run is restart the ssh daemon and enjoy!! :P

/etc/init.d/ssh restart
