I never had any error reading ssh protocol banner errno 10054 issues with it, but today, I have that : SSHException: Error reading SSH protocol banner This is strange because it happens randomly on any connections. Is there any way to fix it ? python paramiko share|improve this question asked Sep 1 '14 at 15:36 FunkySayu 1,9241726 9 This happens if the server accepts the connection but the ssh daemon doesn't respond within 15 seconds. It could be network congestion, faulty switches, etc... but usually it means that the target server is

bogged down or its sshd has hung. Recovery is to wait and try again. If you control the server, its a good time to check on its health. –tdelaney Sep 1 '14 at 16:49 1 You can reproduce this error by making 10 threads and opening/closing sftp connections as fast as you can on all of them. The sshd daemon can't respond in time, and the above exception is thrown. –Eric Leschinski Jan 15 '15 at 20:21 I've just got the issue on one server. Openssh client connects fine, Paramiko fails. If I telnet the server, it doesn't write the line SSH-2.0-OpenSSH_6.0p1 immediately as all other servers do. Have no idea about the cause. –Equidamoid May 25 '15 at 12:55 add a comment| 1 Answer 1 active oldest votes up vote 6 down vote accepted It depends on what you mean by "fix". The underlying cause, as pointed out in the comments, are congestion/lack of resources. In that way, it's similar to some HTTP codes. That's the normal cause, it could be that the ssh server is returning the wrong header data. 429 Too Many Requests, tells the client to use rate limiting, or sometimes APIs will return 503 in a similar way, if you exceed your quota. The idea being, to try again later, with a delay. You can attempt to handle this exception in your code, wait a little while, and try again. You can also edit your transport.py file,

assigned 7 participants Depado commented Feb 3, 2016 Hello, It's been a few days and I'm still struggling with this, I think it's quite a known issue but wasn't able to find a workaround. http://stackoverflow.com/questions/25609153/paramiko-error-reading-ssh-protocol-banner Paramiko 1.16.0 Python 3.5.1 Operating System : Archlinux Below is a simplified version of my actual code that throws the same error : import os import paramiko # Loading ssh configuration to get the IP and user of the desired host (here 'bastion') cfg = paramiko.SSHConfig() with open(os.path.expanduser("~/.ssh/config")) as f: cfg.parse(f) host_cfg = cfg.lookup('bastion') sock = paramiko.ProxyCommand("ssh -W %h:%p {}@{}".format(host_cfg.get('user', 'root'), host_cfg.get('hostname'))) # Client Setup client = paramiko.SSHClient() client.load_system_host_keys() https://github.com/paramiko/paramiko/issues/673 client.set_missing_host_key_policy(paramiko.AutoAddPolicy()) # Connect and execute command client.connect("my.ip.ad.dr", username='root', sock=sock) (stdin, stdout, stderr) = client.exec_command("echo 'Hello World !'") for line in stdout.readlines(): print(line) client.close() Note that the whole parsing the ssh config thing is simplified because I know this entry is in the ssh config. (And yes I'm sure the error doesn't come from that because the generated ProxyCommand is correct) Of course it raises the error when executing the client.connect line. The ProxyCommand is correct, tested multiple times and works just fine in my ~/.ssh/config. When using it with the command line, it creates an entry in the logs of my bastion. When using it within paramiko it doesn't generate an entry in the logs. I also tested using the netcat approach like this : sock = paramiko.ProxyCommand("ssh {}@{} nc %h %p".format(host_cfg.get('user', 'root'), host_cfg.get('hostname'))) This time it generates an entry in the logs of my bastion (even though it still raises this error) but closes the connection immediatly. Anyone having the same issue and could help me with that ? ktbyers commented Feb 3, 2016 @Depado I am having a similar issue connecting to Cisco devices through a proxy.
