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: ssh_exchange_identification: connection closed by remote host ubuntu 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. –shark555 Apr 16

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 http://edoceo.com/notabene/ssh-exchange-identification 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 server-side ~/.ssh/authorized_keys. Along the same lines as this issue, if the files /etc/ssh/*key* are removed and s

Bitbucket Public Issue Tracker master Issues Issues Issue #9685 duplicate SSH hanging up unexpectedly Brian Feaver created an issue https://bitbucket.org/site/master/issues/9685/ssh-hanging-up-unexpectedly 2014-06-10 We're occasionally getting: ssh_exchange_identification: Connection closed by remote host fatal: The remote end hung up unexpectedly Started sometime yesterday and we get them a few times every hour. Doesn't seem to be any particular repo, but they're always our own private repos. Comments (13) Ethan Kaminski This seems to be a recurrence of issue #6331 - several people have complained about it in the past day or so. I've seen this connection closed twice in manually-triggered script runs this week. We have a test server that's maintained using scripts, and those scripts have generated error messages about ssh_exchange_identification. I've not seen the issue (yet) when working locally. 2014-06-11T00:17:54+00:00 Stan Hu I saw this error today when working locally. It failed twice before working again. 2014-06-11T00:19:54+00:00 Gigi Sayfan I just saw it too! amazing! 2014-06-11T01:01:56+00:00 Per Hallgren We are experiencing the same issue on our cronjobs for connection closed by a couple of days. Manually running the script which pulls all repositories gives the same error, for seemingly random repositories. In #6331, some people hinted that it may be only caused if run by cron, but this does not seem to be the case. cat /proc/version Linux version 2.6.32-5-amd64 (Debian 2.6.32-48squeeze1) (dannf@debian.org) (gcc version 4.3.5 (Debian 4.3.5-4) ) #1 SMP Mon Feb 25 00:26:11 UTC 2013 ssh -V OpenSSH_5.5p1 Debian-6+squeeze3, OpenSSL 0.9.8o 01 Jun 2010 git --version git version 1.7.2.5 2014-06-11T10:30:38+00:00 Mark Alexander Out of 96 cronned pulls in the last hour, 48 failed. Can we put this in the "really not good" category? 2014-06-11T15:26:39+00:00 Karthi Mohan I have a Jenkins job which fails randomly with the same error. I have been facing this issue in the last couple of days. stderr: ssh_exchange_identification: Connection closed by remote host fatal: The remote end hung up unexpectedly 2014-06-11T17:06:35+00:00 jsashi It's happening for us as well for the past few days. Atlassian, please fix this soon. Any chance this is happening due to the upgrade to the latest OpenSSL? 2014-06-12T16:42:02+00:00 Markus Stefanko it's happening constantly here, and adding to unexpected behaviour is there a proposed work-around to automatically handle ssh_exchange_identification errors? E.g. a setting to automatically retry such? It seems as if ConnectionAttempts and ConnectTimeout settings in ssh
