Re: [ptp-dev] Set up ControlChannel may causes the connection to remote host hangs up
|
Sure we can install bash on AIX, but it is not part of the standard AIX
code, so I think a "long term solution" is really needed. Thanks.

Re: [ptp-dev] Set up ControlChannel may causes the connection to remote
host hangs up
The Control channel is required because Open SSH server does not support
sending signals to remote processes running on the SSH connection.
Therefore, another bash session is used to retrieve the PID of each
process started by Remote Tools and also used to run the 'kill' command in
order to send signals when needed.
Is it possible to implement something similar with ksh? For a long term
solution, it seems that the Remote Tools connection parameters should also
have an 'environment' parameter that describe which remote interpreter is
being used, and which commands and features are available.
Or is it possible to install bash into a AIX machine?
Best regards,

Hi,
In codes of PTP 2.1 final release, for creating a connection to remote
host, a ControlChannel is set up. In which, a exec chanel with command
"/bin/bash" is created.
This code logic locates in line 68 in class ControlChannel
For AIX system, the default shell is ksh, no bash is installed. So when
connecting to a remote AIX, the command "/bin/bash" is failed and no
terminal path is allocated to the control panel, then it falls in a
end-less loop. This code is in line 99 in class ControlChannel
This causes the UI hangs up there, and user get nothing indication.
Is it possible to fix this problem?
