Ssh_exchange_identification Connection Closed By Remote Host Linux
12 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 ssh_exchange_identification: connection closed by remote host ubuntu 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. git ssh share|improve this question edited Oct 11 '12 at 18:22 Yamaneko 1,83721741 asked Apr 12 '12 at 16:32 MoreFreeze 80421220 How to analysis? Try a "ssh -vvv git@localhost" and check the permissions of .ssh directory (700) and id_rsa(.pub) files (600). See stackoverflow.com/questions/3712443/… or stackoverflow.com/questions/5470680/… for illustration. –VonC Apr 12 '12 at 18:03 Have you generated rsa keys for sshd on server machine? It may also be the case of different ssh versions on client and server machine. &nda
or that sshd needs to be re-configured. This is not the case. Symptoms Connecting to SSH servers gives this message: $ ssh atom@example.com ssh_exchange_identification: Connection closed by remote host Or maybe this if using verbose mode. $ ssh

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 http://edoceo.com/notabene/ssh-exchange-identification 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 server-side ~/.ssh/authorized_keys. Along the same lines as this issue, if the files /etc/ssh/*key* are removed and sshd is not restarted then this error will show up too. Check for the key files in the sshd configuration directory. Heavy Server Load Have also seen this happen when server was under heavy load from for example, brute force attack. Increase the amount of connections sshd can run. root@host # grep MaxSt

Please make sure you have the correct access rights and the repository exists. I don't actually testing, but i thing builder stop posting it host and port to etcd. Or maybe it posting only once for 24 hour TTL. So router cannot route requests to builder. rvadim commented Sep connection closed by 16, 2015 Restart of builder helps, but next issue is: $ git push deis master fatal: 'my-app.git' does not appear to be a git repository fatal: Could not read from remote repository.Please make sure you have the correct access rights and the repository exists.

A good way to receive more details of this trouble will be through the git command using the verbose mode, as the example below: git -vvv git@bitbucket.org It's possible to get the same error message when the machine have more than one network configured to the internet and there are some trouble on only one network, then the error will be intermittent. If it's your case I would suggest you to try connecting using only one network. Could you please try the git using the verbose mode and share the results? Kind Regards, Henrique LechnerCommentDag gruneauJun 13, 2014 Cheers /DagHenrique Lechner [Atlassian]Jun 17, 2014Drag,To do a better troubleshooting on it I would ask you to try to use the git command with the verbose mode, it returns interessing verbose level of the errors.Kind Regards,Henrique Lechner CommentAdd your comment...Sign up or log in to answerWatchRelated questions Powered by Atlassian Confluence 5.7.3, Team Collaboration Software Printed by Atlassian Confluence 5.7.3, Team Collaboration Software.
