I just cloned one of my VMs and created a new server. The Fabric script (which uses paramiko underneath) works
Fabric Error Reading Ssh Protocol Banner
fine one server but not the other. Since it's a clone I don't know what could be different but everytime I run my Fabric script I get the error Error reading SSH protocol banner. This script is connecting with the same user on both servers. The script works fine on all other servers except this new one that I just clones. The only thing that is radically different is the IP address which is totally different range. Any ideas on what could be causing error reading ssh protocol banner mysql this? python linux ssh fabric paramiko share|improve this question asked Aug 26 '11 at 14:33 Mridang Agarwalla 11.8k37130276 add a comment| 2 Answers 2 active oldest votes up vote 7 down vote accepted This issue didn't lie with Paramiko, Fabric or the SSH daemon. It was simply a firewall configuration in ISPs internal network. For some reason, they don't allow communication between different subnets of theirs. We couldn't really fix the firewall configuration so instead we switched all our IPs to be on the same subnet. share|improve this answer answered Aug 31 '11 at 5:04 Mridang Agarwalla 11.8k37130276 I am geting same error. but In my case host is amazon instance what should I do in that case –sagar Oct 23 '13 at 8:25 add a comment| up vote 2 down vote Try changing the banner timeout from 15 seconds to 30 secs in the transport.py file. Also, it could be that the sshd daemon on the server is hung. Can you SSH into it manually? share|improve this answer answered Aug 26 '11 at 16:33 Gabriel Ross 3,28311625 I edited transport.py and changed the timeout to 30 seconds but it didn't help. I can SSH to the server manually and execute all the commands. Weird issue. –Mridang Agarwalla Aug 27 '11 at 11:34 Hi Gabriel, could this be caused by a network issue? –Mridang Agarwalla Aug 29 '11 at 18:15 I just ran a traceroute from my Fabric server to the Server

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 https://github.com/paramiko/paramiko/issues/673 : 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() 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
