As you see below, is it possible to save the result? Cause, at second and third stdout.read() I couldn't reach the result.
import paramiko
import os
dssh = paramiko.SSHClient()
dssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
dssh.connect('192.168.1.250', username='root', password='pass')
import os
stdin, stdout, stderr = dssh.exec_command('ifconfig')
print stdout.read()
print ('Sleeping 2 seconds!')
os.system('sleep 2')
stdin, stdout, stderr = dssh.exec_command('ls -l')
print stdout.read()
print stdout.read()
print stdout.read()
dssh.close()
Imagine that stdout
is an ordinary file. What do you expect to get if you call file.read()
the second time? -- nothing (empty string) unless the file has changed outside.
To save the string:
output = stdout.read()
You might find Fabric simpler to use (it uses paramiko
to execute commands under the hood).
You can try this Generic API
def ssh_ctrl(ip, user, password,cmd):
ssh = paramiko.SSHClient()
ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
try:
ssh.connect(hostname=ip, username=user, password=password, timeout=tout, compress = True,look_for_keys=False, allow_agent=False)
except (socket.error,paramiko.AuthenticationException,paramiko.SSHException) as message:
print "ERROR: SSH connection to "+ip+" failed: " +str(message)
sys.exit(1)
stdin, stdout, ssh_stderr = ssh.exec_command(cmd)
out = stdout.read()
stdin.flush()
ssh.close()
return out
