Cisco MDS login and show commands (wodSSH / wodSSH.NET)

by VBrookie, Thursday, January 26, 2006, 18:44 (6673 days ago)

I'm trying to write a basic VB program using Visual Studio 2005.
The goal is to telnet or SSH to a Cisco MDS Fiber Channel Switch, and run some basic commands, which will eventually be sent to a text file.

This is what I see when I telnet or SSH using SecureCRT.

MDS-Top#

--------- End Paste ---------

Presently this the code I'm using

------- Start Paste ---------

Public Class Form1
Dim WithEvents Ssh1 As WeOnlyDo.Client.SSH
Public SSHCommand As String = show version

Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) _
Handles MyBase.Load
Ssh1 = New WeOnlyDo.Client.SSH() ' Initialize new instance
Ssh1.Blocking = True
Ssh1.Login = admin ' Set your login/username
Ssh1.Password = password ' Set your password
Ssh1.Encryption = WeOnlyDo.Client.SSH.EncryptionMethods.Auto ' Any encryption is ok
' Ssh1.Protocol = WeOnlyDo.Client.SSH.SupportedProtocols.Telnet
Ssh1.Protocol = WeOnlyDo.Client.SSH.SupportedProtocols.SSH1 ' Set SSH version
Ssh1.Prompt = MDS-Top#
Ssh1.Hostname = 1.1.1.1
Ssh1.Connect( 1.1.1.1 ) ' Connect, finally. Now wait for Connected event to occur
'Ssh1.WaitFor( MDS-Top# , 5)
'Ssh1.Execute( show version , MDS-Top# , 5)
'Ssh1.Execute( show version & Chr(10), # , 5)

TextBox1.Text = Ssh1.Receive

End Sub

End Class

--------- End Paste ----------

When I run it (as it stands right now) I get all of the output upto an d including MDS-Top# . However when I uncomment any of the Ssh1.Execute commands I get a timeout due to in activity.
If I attempt to add Ssh1.command= show version & vblf It tells me that the stdin: line is not tty

What the heck am I missing? It probably easy, but I haven't messed around with VB for a couple of years and the old brain doesn't ramp up as quickly as it used to.

Any help is appreciated.

Thanks

VBRookie,

try something like this:
[code]Ssh1.Connect( 1.1.1.1 ) ' Connect, finally. Now wait for Connected event to occur
Ssh1.WaitFor( MDS-Top# , 5)
Ssh1.Execute( show version & Chr(10), MDS-Top# , 5)[/code]

that must work. Otherwise, you can also call

Ssh1.Send( show version & chr(10))

and then call Ssh1.Receive - that's also a way to go.

Kreso,
I tried both of these with different results.

[code]
Ssh1.WaitFor( MDS-Top# , 5)
ssh1.execute( show version & Chr(10), MDS-Top# , 5)
[/code]
The execute command timed out due to inactivity
[code]
Ssh1.WaitFor( MDS-Top# , 5)
Ssh1.Send( show version & chr(10))
TextBox1.Text = Ssh1.Receive
[/code]
This one didn't return any data to Textbox1.

This device is on my local LAN so the response should be almost immediate.

Any thoughts?

Maybe it did. Maybe it was just newline? You should call it more than once until you see what is actually returned, and then tweak execute method to fit returned data.
Perhaps you never got Execute to returned because prompt was never received? What if 'press any key...' was shown?
Also, add to TextBox, don't overwrite it.

Talk about Tech Support
[:wink:]
Any idea about the inactivity timeout?

And a really stupid question, how to you add to the textbox?

Ignore inactivity timeout for now. First determine what's received, then tweak Execute method to catch that received data. Once you do it, you will not worry about timeout since planned and expected data/prompt will be returned.

As for adding to textbox,

TextBox1.Text = TextBox1.Text + Ssh1.Receive
