Code: Select all

login_user = 'xyz'
login_pass = 'xyz'
ssh = paramiko.SSHClient()
ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
ssh.connect(device, username=login_user, password=login_pass, look_for_keys=False, timeout=5)
print "success loggedin"
stdin, stdout, stderr = ssh.exec_command("term len 0 ; show int desc | i Tu ; show ip interface brief | in Tunnel ; show ip bgp vpnv4 vrf AWS summary | i 169.25 ; show ip route vrf AWS bgp")
all_output = stdout.read()
print all_output

Oben ist mein Code -Snippet, der nur einen Befehl übergibt, druckt die Ergebnisse in Ordnung, aber mit mehreren Befehlen wie oben funktioniert es nicht (keine Ausgabe). Das Gerät, auf das angemeldet ist, ist ein Cisco ASR1006 - hat es etwas mit dem Gerät zu tun? />Ssh.Connect benötigt für jede Befehlsausführung? < /p>

ssh.connect(device, username=login_user, password=login_pass, look_for_keys=False)
stdin, stdout, stderr = ssh.exec_command('show int desc | i Tu')
vpc_ints = stdout.read()
ssh.connect(device, username=login_user, password=login_pass, look_for_keys=False)
stdin, stdout, stderr = ssh.exec_command('show ip interface brief | in Tunnel')
vpc_peers = stdout.read()
ssh.connect(device, username=login_user, password=login_pass, look_for_keys=False)
stdin, stdout, stderr = ssh.exec_command('show ip bgp vpnv4 vrf AWS summary | i 169.25')
vpc_bgp_routes = stdout.read()
ssh.connect(device, username=login_user, password=login_pass, look_for_keys=False)
stdin, stdout, stderr = ssh.exec_command('show ip route vrf AWS bgp')
ip_routes_list = stdout.read()
< /code>



Wie in Kommentaren vorgeschlagen, habe ich auch versucht, exec_command < /code> mehrmals über einer Verbindung anzurufen: < /p>

ssh.connect(device, username=login_user, password=login_pass, look_for_keys=False)
stdin, stdout, stderr = ssh.exec_command('show int desc | i Tu')
vpc_ints = stdout.read()
#ssh.connect(device, username=login_user, password=login_pass, look_for_keys=False)
stdin, stdout, stderr = ssh.exec_command('show ip interface brief | in Tunnel')
vpc_peers = stdout.read()
#ssh.connect(device, username=login_user, password=login_pass, look_for_keys=False)
stdin, stdout, stderr = ssh.exec_command('show ip bgp vpnv4 vrf AWS summary | i 169.25')
vpc_bgp_routes = stdout.read()
#ssh.connect(device, username=login_user, password=login_pass, look_for_keys=False)
stdin, stdout, stderr = ssh.exec_command('show ip route vrf AWS bgp')
ip_routes_list = stdout.read()
ssh.close()
< /code>

Aber das fällt mit: < /p>
