probably problems with buffer (General questions)

Goodmorning,

Firstly sorry for my bad english!

I'm usig trial version of wodSSH in a Visual Basic .NET Windows Application.
I don't know Unix absolutely but I'm a .NET developer so a friend of mine has given to me a Unix command to execute on the Unix server and show the answer on a textbox.

If I go to the Server with the client Putty and I execute this command the answer is:

Calls Voice Service Caller Dialed
Channel Today Service Status Input Digits
0 0 *Manoos
1 26 *On Hook
2 26 *On Hook
3 26 *On Hook
4 26 *On Hook
5 26 *On Hook
[...]
120 25 *On Hook
121 25 *On Hook
122 25 *On Hook
123 26 *On Hook
124 26 *On Hook
125 26 *On Hook
126 26 *On Hook
127 26 *On Hook

Otherwise if I execute this command from my Windows Application using wodSSH the answer is limited to the row 104 (not complete) as follow:

Calls Voice Service Caller Dialed
Channel Today Service Status Input Digits
0 0 *Manoos
1 26 *On Hook
2 26 *On Hook
3 26 *On Hook
4 26 *On Hook
5 26 *On Hook
[...]
100 26 *On Hook
101 25 *On Hook
102 25 *On Hook
103 25 *On Hook
104 25 *On

Whats the problem?
How can I resolve it?

HELP ME!!!

Thanks.

Hi Paolo,

Can you try something like this:
--------------------------------------------
ssh1.Hostname = your_hostname
ssh1.Login = your_login
ssh1.Password = your_password
ssh1.Blocking = True
ssh1.Connect()

ssh1.WaitFor( regex:[\$ #>] $ )
ssh1.DataReady = 0
TextBox1.Text = TextBox1.Text + (ssh1.Execute( YOUR COMMAND + vbLf, regex:[\$ #>] $ , 30))
--------------------------------------------

More help for Execute Method you can find here:

Let us know how it goes.

Hi,

thanks for your answer.

In my Form I wrote:

Private Sub Button1_Click(ByVal sender As System.Object,
ByVal e As System.EventArgs)
Handles Button1.Click

ssh1.Authentication = WODSSHLib.AuthenticationsEnum.authPassword
ssh1.Hostname = <MYSERVER>
ssh1.Login = <MYLOGIN>
ssh1.Password = <MYPASSWORD>
ssh1.Command = shmview -sysmon + Chr(10)
ssh1.Protocol = WODSSHLib.ProtocolsEnum.SSH2
ssh1.Connect()
End Sub

Private Sub ssh1_Received(ByVal sender As Object,
ByVal e As AxWODSSHLib._IwodSSHEvents_ReceivedEvent)
Handles ssh1.Received

Dim arrReceived() As String
arrReceived = Split(ssh1.Receive.ToString(), Chr(10))
Dim st As String
TextBox1.Text =
For Each st In arrReceived
TextBox1.Text = TextBox1.Text + st + vbCrLf
Next
ssh1.Disconnect()
End Sub

but the result is what I exposed in my first post.
With your code I have not answer.

Paolo,

I'm not sure why it isn't working because I cannot send your command on our server.

Why don't you try with Execute Method instead using Command Method.

Here is complete sample:
-------------------------------------------------------
ssh1.Protocol = WODSSHCOMLib.ProtocolsEnum.SSH2
ssh1.Hostname = your.hostname
ssh1.Login = your.login
ssh1.Password = your.password
ssh1.Blocking = True
ssh1.Connect()

ssh1.WaitFor( regex:[\$ #>] $ )
ssh1.DataReady = 0
TextBox1.Text = TextBox1.Text + (ssh1.Execute( shmview -sysmon + vbLf, regex:[\$ #>] $ , 30))
-------------------------------------------------------

Let us know how it goes.

Goodmorning and Happy New Year!

Sorry the late but I'm not at work for my holiday.

Ok.

I tried your code but at the command

ssh1.WaitFor( regex:[$ #>] $ )

the application wait some seconds and after has a timeout error.

Maybe the problem is about the prompt regex:[$ #>] $ but I don't know Unix so I can't understand if this prompt is the same of my system.

How can I verify it?

Thanks.

Hans,

When you connect to server and before you send some command you will receive prompt.
Here is my prompt that I receive when I connect to my server:

drazen@debian:~$

You can check out prompt in putty and us it as a prompt in your code.

Here is how I successfully use it:
[code]
ssh1.WaitFor( drazen@debian:~$ )
ssh1.DataReady = 0
TextBox1.Text = TextBox1.Text + (ssh1.Execute( ls -al + vbLf, drazen@debian:~$ , 30))
[/code]

Let us know how it goes.

Hello,

this is what I can see on Putty after Logon:

My propmpt is TERM=[xterm]? ?

Thanks.

Hans,

Yes, this is probably your prompt. When command is executed did you receive same prompt?
[code]
ssh1.WaitFor( TERM=[xterm]? ) //first prompt before command is executed
ssh1.DataReady = 0
TextBox1.Text = TextBox1.Text + (ssh1.Execute( shmview -sysmon + vbLf, here goes prompt after command is executed , 30))
[/code]

If problem persist any chance that we can connect to your server and try to resolve your problem? You can send your private information to techsupport@weonlydo.com

Hi,

In my last post I've sent what Putty show after Logon but it was not correct.
Here you are the correct version to execute ls commad:

login as: presidio
presidio@10.41.54.11's password:

As you can see after logon the prompt is TERM=[xterm]? and the command ls don't run so I've an error and the prompt change to oppvmi-ir1.sky.local(presidio) .
Now the command ls ca run correctly.

My system is a SunOS 5.8.

Thanks.
