Tutorial 12: Terminal¶

API¶

Module hydratk.lib.network.term.client Method TermClient is factory method which requires attribute engine to create proper TermClient object instance. Additional attributes are passed as args, kwargs.

Supported protocols:

• SSH: module ssh_client
• Telnet: module telnet_client

Methods:

• connect: connect to server

• disconnect: disconnect from server

• exec_command: execute command on server

  Note

  API uses HydraTK core functionalities so it must be running.

SSH¶

# import library
import hydratk.lib.network.term.client as term

# initialize client
client = term.TermClient('SSH')

# connect to SSH server using password, certificate
# returns bool
client.connect(host='127.0.0.1', port=22, user='aaa', passw='bbb')
client.connect(host='127.0.0.1', port=22, user='aaa', cert='/home/lynus/key.pri')

# execute commands
# returns bool, stdout lines or stderr lines

# print working directory
print client.exec_command('pwd')

# make directory
client.exec_command('mkdir pokus')

# create file
client.exec_command('touch evil')

# delete file in interactive mode
# Y is sent to stdin
client.exec_command('rm -i evil', 'Y')

# execute script
client.exec_command('./pok.sh')

# disconnect from server
# returns bool
client.disconnect()

Telnet¶

# import library
import hydratk.lib.network.term.client as term

# initialize client
client = term.TermClient('TELNET')

# connect to Telnet server
# returns bool, lines
res, out = client.connect('freechess.org', 23)

# execute command
# returns bool, lines
res, out = client.exec_command('login')
res, out = client.exec_command('password')
res, out = client.exec_command('help')

# disconnect from server
