Hello world,

When I do make, I do see that the Expect tool is being install with option --with-tcl=/root/Desktop/DWAS_DEVELOPMENT/uclinux_2009R1_537/uclinuxdist-2009R1/user/tcl/build,

I dont see any directory uclinuxdist-2009R1/user/tcl/build !

What am I missing for the Expect tool to be added?

Hi Mike,

Thanks,the image got created,but when I execute the Expect command, it complains fork: function not implemented.

I am trying to figure out how to run Expect without fork option.

The following is the error

root:/> expect -d scpkey.sh

expect version 5.42.1

argv[0] = expect  argv[1] = -d  argv[2] = scpkey.sh

set argc 0

set argv0 "scpkey.sh"

set argv ""

executing commands from command file scpkey.sh

spawn scp /root/.ssh/id_rsa.pub root@x.x.x.x:/root/.ssh/authorized_keys

fork: function not implemented

    while executing

"spawn scp "/root/.ssh/id_rsa.pub" "root@x.x.x.x:/root/.ssh/authorized_keys""

    (file "scpkey.sh" line 2)

The following is the script I am using to do a scp with the help of Expect

#!/usr/bin/expect

spawn scp "/root/.ssh/id_rsa.pub" "root@x.x.x.x:/root/.ssh/authorized_keys"

set timeout 90

expect {

  -re ".*(yes/no)?:.*" { send "yes\n"; interact }

-re ".*password:.*" { send "xxxx\n"; interact }

  eof { exit }

  timeout { puts "\n--TIMEOUT!--\n";exit}

}

exit

expect will probably need a bit of work to use vfork() when spawning things, but i dont think the "fork" command will ever work

Hello Mike,

So if i want to execute the following script,what modifications do i need to make?

Do you mean to say I should not use spawn?

#!/usr/bin/expect -f

set force_conservative 0  ;# set to 1 to force conservative mode even if

              ;# script wasn't run conservatively originally

if {$force_conservative} {

    set send_slow {1 .1}

    proc send {ignore arg} {

        sleep .1

        exp_send -s -- $arg

    }

}

set timeout -1

spawn scp /root/.ssh/id_rsa.pub root@x.x.x.x:/root/.ssh/authorized_keys

match_max 100000

expect -re ".*(yes/no)?.* "

send -- "yes\r"

expect -re ".*password:.* "

send -- "xxxx\r"

expect eof

this warning:

INFO: task expect:162 blocked for more than 120 seconds.

indicates that the code might need a little more tweaking ... such as a vfork child waiting for info from the parent, but the parent cant notify it until the child does a vfork, and then it stays that way until the kernel warns about the parent being blocked.

Hello world,

There is a directory in the path 2010R1/user/expect/patches, do I need to apply this patch before I do compile the kernel image? If no, can I please get some guidance for using the expect tool in the uclinux 2010 version?
