All,
I’m trying to launch a server remotely, but all the Net:SSH calls I try
never seem to return…they just hang.
My Code:
cmd = “nohup ./Servers/BARKSproxy.pl &”
Net::SSH.start(host[:ip], host[:user], :password => host[:passwd]) do
|ssh|
rc = ssh.exec(cmd)
or
rc = ssh.exec!(cmd)
or
ssh.open_channel do |ch|
ch.exec(cmd) do |cc, success|
abort “Could not run program” unless success
cc.on_data do |dd, data|
puts "STDOUT>>#{data}"
end
cc.on_extended_data do |ch, type, data|
puts "STDERR>>#{data}"
end
cc.on_eof do |ch|
puts "EOF>>"
ch.close
end
cc.on_close do |ch|
puts "Channel is Closing!"
end
end
end
ssh.loop
end
All of these never return from the exec call. I am using Net::SSH v2.
I am running the program from my PC to a large HP/UX host. The
‘BARKSproxy.pl’ program starts and is running…but my local ruby
program never returns. The ‘Timeout’ options doesn’t seem to be working
either, as it will sit overnight, never returning. It looks like its
locked up.
Is there some special way to start a background process using SSH??
I’ve tried using another perl script to start the other one, but still
get a hung exec. …getting ready to pull what little hair is left, out
