spawn from a spawned process Posted by awalia (awalia), 7 August 2005 I have a scenario, when I log in to a router by telnet, and then I want to initiate a ftp session from the router to get a file. I want to use expect to do it, I use the following spawn telnet 192.168.2.4 expect "login:" {send "xyz\r"} expect "Password" {send "default\r"} expect "router>" {send "cd \tmp\r"} expect "router\tmp>" at this point, I want to initiate a ftp session to a server say 192.168.19.7 , I do not know how to proceed as if I do "spawn ftp 192.168.19.7" it will open a ftp session from my linux workstation, where as intent is to open it from the router, get the file and quit from the ftp session and then continue to configure the router. any help will be highly appreciated. Posted by admin (Graham Ellis), 7 August 2005 If you want to spawn another process on the same machine that you're running the current script on, then save the spawn_id and you can then spawn the second process. If you want to spawn a process on a remote machine you've s telnet'ed (or ssh'd) to, you should ensure that expect is available on that machine too and that a script to run the ongoing process is there. From your description, I believe you have the second scenario. It's quite unusual to have to "double bank" expect like this, and it can be hard to debug and support. I suggest that you might tdo better running commands directly in the remote shell and controlling them from the first telnet session; that way, all your program remians on the one machine. Posted by awalia (awalia), 8 August 2005 Thanks for the reply. Yes, your guess was correct, I was trying for the 2nd. I tried your suggestion and it works, I used send "ftp 192.168.19.7" and not spawn "ftp 192.168.19.7" thanks and regards This page is a thread posted to the opentalk forum
