I new in python, I am try to connect RHEL vm by key authentication.I have two RHEL6.5 vm1,vm2 and Python 2.6.6 on both.
First I generate keys on vm1 and copy to vm2 as using below cmd.
On vm1 execute below cmd:
1) ssh-keygen -t rsa
2) After key generation
3) ssh-copy-id -i .ssh/id_rsa.pub root#vm2
After that I am able to login that vm2 from vm1
ssh -i /root/.ssh/id_rsa root#vm2
manually this is working fine but i am doing it programmatically by using python, below is my code: run from vm1
SSHKey.py
import paramiko
sshcon = paramiko.SSHClient()
sshcon.set_missing_host_key_policy(paramiko.AutoAddPolicy())
connection = sshcon.connect('vm2', 'root','/root/.ssh/id_rsa')
print "-----------------"
print connection
**OutPut:**
Traceback (most recent call last):
File "SSHKey.py", line 5, in <module>
connection = sshcon.connect('vm2', 'root')
File "/usr/lib/python2.6/site-packages/paramiko/client.py", line 277, in connect
socket.getaddrinfo(hostname, port):
socket.gaierror: [Errno -8] Servname not supported for ai_socktype
I think RHEL6.5 vm1 not able to communicate with RHEL6.5 vm2.Python version looks good you need to install paramiko on RHEL6.5 vm2.Run below cmd.
1) yum list python-paramiko --showduplicates
This will give you available package
2) yum install python-paramiko
This will install paramiko on your rhel vm.

Using python:
I am able to run show commands using Connecthandler .send.command:
from netmiko import ConnectHandler
import subprocess
Network_Device = {"host": "10.111.22.333", "username": "USER123", "password": "Pass123", "device_type": "cisco_xr",}
Connect = ConnectHandler(**Network_Device)
Connect.enable()
version1 = "show version"
print(Connect.send_command(version1))
But not able to run 'df' or 'ls' commands, as not able to reach bash prompt i reach by running 'run' command on router.
I tried:
disk1files = subprocess.run("df", stdout=subprocess.PIPE)
print(disk1files.stdout.decode())
But seems its wrong. Please suggest the right library or code I can use here.
This is my first question here, so bear some silly questions or mistakes done in code
if on DF you are referring to "Don't fragment" then it is posible to send it like
Connect.send_command("ping 192.168.10.10 df-bit size 1600")
where 1600 represents MTU, and for ls commands is link command,
Connect.send_command("ls-active")
Connect.send_command("ls-active-enabled")
but if you are referring to df and ls in linux (disk free and list files..) then you can use os module for sending commands:
import os
os.system("ls -l")
or use call from subprocess module:
from subprocess import call
call(["ls", "-l"])
If you need to acccess cisco bash:
switch# configure terminal
switch(config)# feature bash-shell
switch# run?
run Execute/run program
run-script Run shell scripts

Thanks for your help,
The error looks like the environment variable HOMEDRIVE is not set, even though it has a value according to your test (the library installer uses it to copy some files).
Can you try this - manually set it, and straight after that run the pip - in the same Command Prompt (cmd) session:
set HOMEDRIVE=C:

It seems to be related to setuptools_scm but reinstallation did not change anything. The internet access shouldn't be a problem since I have successfully installed a local version of the package.
I have just finished installing AWS CLI tools on an old RHEL 5.10 machine, this works for me as on date.

EDIT 2017-03-31: Zachary said that gcloud 148.0.0 addressed this issue. So try gcloud components update. see https://stackoverflow.com/users/4922212/zachary-newman
tl;dr
It turns out that socket.gethostbyaddr(socket.gethostname()) is slow for .local hostname in macOS.
$ python -i
>>> socket.gethostname()
'hiroshi-MacBook.local'
>>> socket.gethostbyaddr(socket.gethostname()) # it takes about 5 seconds
('localhost', ['1.0.0.127.in-addr.arpa'], ['127.0.0.1'])
So, for a workaround, just added the hostname to the localhost line of /etc/hosts.
127.0.0.1 localhost hiroshi-Macbook.local
After that is return value is different, but it returns in an instant.
>>> socket.gethostbyaddr(socket.gethostname())
('localhost', ['1.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.ip6.arpa'], ['::1'])
How do I get there
Where gcloud command is:
$ which gcloud
/Users/hiroshi/google-cloud-sdk/bin/gcloud
Edit the endline of the shell script...
...
+ echo "$CLOUDSDK_PYTHON" $CLOUDSDK_PYTHON_ARGS "${CLOUDSDK_ROOT_DIR}/lib/gcloud.py" "$#"
"$CLOUDSDK_PYTHON" $CLOUDSDK_PYTHON_ARGS "${CLOUDSDK_ROOT_DIR}/lib/gcloud.py" "$#"
to echo where the gcloud.py is:
$ gcloud
python2.7 -S /Users/hiroshi/google-cloud-sdk/lib/gcloud.py
OK. Who take the 5 secs?
$ python2.7 -S -m cProfile -s time /Users/hiroshi/google-cloud-sdk/lib/gcloud.py

_socket.gethostbyaddr is.
What is the argument of the function call and backtrace look like?
I added some lines before main() of gcloud.py
import traceback
def mygethostbyaddr(addr):
print addr
traceback.print_stack()
return addr
import socket
socket.gethostbyaddr = mygethostbyaddr
Execute gcloud again.
I got it is my .local name of my machine.

#hiroshi's answer solved the issue for me i.e. to run gcloud components update. However, since I had installed gcloud through their Cloud SDK using a package manager, I was stuck with the following error*:
ERROR: (gcloud.components.update) You cannot perform this action
because the Google Cloud CLI component manager is disabled for this
installation.
Hence, I had to explicitly mention the apt-get libraries to perform the update. The following command helped me to get it done in one go:
sudo apt-get update && sudo apt-get --only-upgrade install google-cloud-sdk-app-engine-go google-cloud-sdk-datastore-emulator google-cloud-sdk-datalab google-cloud-sdk-firestore-emulator google-cloud-sdk-kubectl-oidc google-cloud-sdk google-cloud-sdk-app-engine-python-extras google-cloud-sdk-cloud-build-local kubectl google-cloud-sdk-cbt google-cloud-sdk-minikube google-cloud-sdk-skaffold google-cloud-sdk-cloud-run-proxy google-cloud-sdk-pubsub-emulator google-cloud-sdk-config-connector google-cloud-sdk-gke-gcloud-auth-plugin google-cloud-sdk-kpt google-cloud-sdk-local-extract google-cloud-sdk-nomos google-cloud-sdk-app-engine-grpc google-cloud-sdk-bigtable-emulator google-cloud-sdk-app-engine-python google-cloud-sdk-terraform-validator google-cloud-sdk-anthos-auth google-cloud-sdk-spanner-emulator google-cloud-sdk-app-engine-java

This appears to be an error caused by failing to pin the py2neo dependency to a specific version. This project was written using py2neo 2.0.7 but failed to pin that version, as py2neo 3.0 is now being pulled in a few things are breaking.
We will push an update for 3.0 soon, in the meantime you can get around this by uninstalling py2neo and installing version 2.0.7:
