For my current project, I am attempting to remotely install an "environment" on a machine using a Python script. This particular environment requires the user name and password to be passed to it. Despite trying various approaches, I have not been successful in getting it to work as expected. The closest I have come is with this script, but even then, a GUI popup appears requesting the password after passing the user name. I'm puzzled about what I might be doing wrong or how I can modify the script to achieve the desired outcome. Below is a snippet of the script involving pexpect:
import os
import pexpect
cmd = 'ssh -X groupName@machineName cd ~/theLocationOfTheInstallation/ && pwd && theFullPathOfTheFileToInstall'
child = pexpect.spawn(cmd)
cmd_show_data = ''
usr = 'userName'
pas = 'myPassword'
while not child.eof():
index = child.expect(['Please enter your.*','pass.*', pexpect.EOF, pexpect.TIMEOUT])
cmd_show_data += child.before
child.delaybeforesend = 1
if index == 0:
print 'user name required, "'+usr+'" is passed'
child.sendline(usr)
elif index == 1:
print 'password required, "'+pas+'" is passed'
child.sendline(pas)
elif index == 2 :
print 'EOF'
elif index == 3:
print 'TIMEOUT'
cmd_show_data += child.before
cmd_show_data = cmd_show_data.split('\r\n')
for s in cmd_show_data:
print s
There is a GUI prompt that appears, which you can view here: https://i.stack.imgur.com/w4gcW.png. If I manually enter the password (which I intend to avoid), the output looks something like this:
user name required, "userName" is passed
TIMEOUT
TIMEOUT (multiple occurrences)
user name required, "userName" is passed
TIMEOUT
TIMEOUT (multiple occurrences)
password required, "myPassword" is passed
TIMEOUT
TIMEOUT (multiple occurrences).... until the installation completes.
If anyone has any insights or suggestions, they would be greatly appreciated.
