Manage Network Devices

NetCmdlets is a comprehensive framework of PowerShell cmdlets for monitoring and managing network devices through standard Internet protocols. With NetCmdlets and Windows PowerShell, admins can easily script common network management tasks including router configuration, switch port monitoring, directory access, VLAN administration, remote execution, and more!

Control Routers, Switches, and Other Devices via SNMP

The easy-to-use get-snmp and set-snmp Cmdlets make working with SNMP capable devices straightforward and intuitive. Administrators can easily automate and script processes for monitoring bandwidth, throughput, up-time, or any number of other network management capabilities.

NetCmdlets gives administrators a powerful set of tools for scripting and automating common network management tasks. For example, finding all of the manageable SNMP agents on a network is as simple as importing the NetCmdlets library and calling get-snmp with a broadcast address:

param( [string] $ipaddress = "255.255.255.255" )

if(!(Get-Module | Where {$_.Name -eq "NetCmdlets"})) {
  Import-Module "NetCmdlets"
}

get-snmp -agent $ipaddress -oid sysName.0

Manage Linux, MacOS, and Unix from Windows

NetCmdlets gives administrators the ability to connect PowerShell scripts to remote Linux/Unix/MacOS systems, and execute commands remotely using standard networking protocols like SSH, Rexec, RShell, Telnet, and more! Through straightforward and easy-to-use cmdlets it is possible to securely automate and orchestrate remote systems from Windows.

Invoke-SSH

For secure shell connections, NetCmdlets provides the Invoke-SSH cmdlet. Below is an example of connecting to a remote SSH server to execute the “ls” command.

PS> invoke-ssh -server myserver -user myuser -password mypassword -command ls

Invoke-Rexec and Invoke-Rshell

Rexec and Rshell (rsh.exe) already exist as command line applications, but until
now they did not return useful, easily scriptable objects in PowerShell.

Below is an example of using Invoke-Rexec to issue a directory listing command to
a remote rexec host:

PS> invoke-rexec -server server -user user -password pass
-command "C:\WINDOWS\system32\cmd.exe /c dir c:\"

PS>

Similarly, the Invoke-Rshell cmdlet gives the same output:

PS> invoke-rshell -server server -user user -password pass
-command "C:\WINDOWS\system32\cmd.exe /c dir c:\"

Invoke-Telnet

The Invoke-Telnet cmdlet may be used to execute a command via a telnet session. The cmdlet will connect, authenticate, wait for the specified Shell prompt to be returned by the server, and then execute the command. For instance:

PS> invoke-telnet -user test -password test -server MyServer
-command ls -shellprompt bash-2.05a$
