Shellstream is disposed when receiving huge response

[katomark]

Hi Guys,

Need your help to resolve my issue.
I send a ssh command to my router "show bgp nei xxx advertised-route", the response is huge and need more than 15 minutes to complete.
If I save the response, the size is 600Mb.

The problem occur when I send the second command, it was said that the shellstream is disposed while my ssh connection is still open.

System.ObjectDisposedException: Cannot access a disposed object.
Object name: 'Renci.SshNet.ShellStream'.
at Renci.SshNet.ShellStream.Write(String text)
at esihaur.SSH.SSHJob.WriteToStream(String command)

void WriteToStream(string command) { if (isConnected) { ca_Shell.Write(command); ca_Shell.Flush(); } }

public bool isConnected { get { return (ca_client != null && ca_client.IsConnected); } }

Please share guys if any solution

Thank You

You can use ShellStream.CanWrite to check if the ShellStream is still open. Not sure why it is closing, maybe the server has a timeout

If I enable paging (-- More --) the connection can stay for hours,, because i need to send " " each time it appear. But I have small issue here.
So i try to disable the paging, but it's disposed after it receive huge response.

ShellStream.CanWrite doesn't resolve my issue. It just resolve the exception.
I tried this

if (!ShellStream.CanWrite) RecreateStream()

it start the process from the beginning of ssh session, I need to handle the login again.
