Re: Couldn't wait for ssh process: No child processes



Read the first part of my original email where swatch can launch script2
directly and it will work when I tee the output but fails without piping the
output to tee. This makes me think that it's something related to the
timing or relationship of the child process spawning by the sftp code.

Also, if you Google this error message, you will see that someone had the
same problem launching sftp from SAP via a script. So it doesn't seem to
matter what is launching the sftp command but there has to be something
in common.

Look at what exactly swatch spawns. Script1 will spawn a shiny new shell
for script2, swatch probably doesnt.

I am using swatch to monitor the vsftpd log and the secure log for FTP
and SFTP inbound transfers then trigger a script to send the file
outbound. When I use the sftp command to send a file outbound, I am
getting "Couldn't wait for ssh process: No child processes" with a
return code of 255. Here's the strange thing:

swatch -> script2.sh -> sftp command -> fails with RC 255
swatch -> script1.sh -> script2.sh -> sftp command -> successful with RC 0
swatch -> script2.sh -> sftp command piped through tee -> successful with
RC 255

Script1.sh is just a simple script that calls script2.sh with the same
arguments that swatch passed from the log line.
