Exscript is a Python module and a template processor for automating network connections over protocols such as Telnet or SSH. We attempt to create the best possible set of tools for working with Telnet and SSH.
Exscript also provides a set of tools and functions for sysadmins, that simplify regular expression matching, reporting by email, logging, or syslog handling, CSV parsing, ip address handling, template processing, and many more.
Exscript may be used to automate sessions with routers from Cisco, Juniper, OneAccess, Huawei, or any others. If you want to configures machines running Linux/Unix, IOS, IOS-XR, JunOS, VRP, or any other operating system that can be used with a terminal, Exscript is what you are looking for.
- Exscript provides high reliability and scalability. Exscript is used by some of the world's largest ISPs to maintain hundreds of thousands of sessions every day.
- Exscript is extremely well tested. The Exscript public API has almost 100% test coverage.
- Exscript is protocol agnostic, so if you are migrating from Telnet to SSH later, you can switch easily by simply changing an import statement.
from Exscript.util.start import start
from Exscript.util.file import get_hosts_from_file
from Exscript.util.file import get_accounts_from_file
def do_something(job, host, conn):
conn.execute('uname -a')
accounts = get_accounts_from_file('accounts.cfg')
hosts = get_hosts_from_file('myhosts.txt')
start(accounts, hosts, do_something, max_threads=2)Check out the Python tutorial:

Create a file named test.exscript with the following content:
uname -a
To run this Exscript template, just start Exscript using the following command:
exscript test.exscript ssh://localhost
Awesome fact: Just replace ssh:// by telnet:// and it should still work with Telnet devices.
