[JSch-users] pty flag works for su command but hangs for sudo.

[prakash b. <jpr...@ya...>]

Hi ,
 
I am trying to run an interactive su and sudo command from my webapplication on a remote host which is Linux.

Since this an interactive command and prompts for the password, I have set the pty as shown below.
 
((ChannelExec)channel).setPty(true);
 
The su command works, but the sudo command is irresponsive(hangs).
Am I missing something here like setting the pty type, dimensions etc. 
 
thanks,
Prakash
