Hi,

First of all, thanks so much for taking the time to help me.

 

I am trying to call an expect script from php using the exec function. I am
able to call other shell scripts, so I see that the exec function is working
as expected.

The script I am running works from the command line, but hangs every time I
try to call it from the browser in php. I saw a similar post by Fabian Borot
in 2005, and followed the suggestions there. They helped me progress, but
not get all the way there!

 

I suspect that the problem is occurring when the script expects are prompt -
what would the prompt that php 'sees' look like? I've tried to make the
prompt more general by putting only the end of it in, and like I said it
does work on the command line.

Does anyone have any idea what I can change?

 

Here is the active part of the expect script: (I've replaced sensitive
information with xxx)

 

set timeout -1

#spawn $env(SHELL)

spawn /bin/bash

match_max 100000

expect -exact " easy-rsa\]# "

send -- ". ./vars\r"

expect -exact " easy-rsa\]# "

send -- "./build-key $argv\r"

expect -exact "

Country Name (2 letter code) \[xxx\]:"

send -- "xx\r"

expect -exact "US\r

State or Province Name (full name) \[xx\]:"

send -- "xxxx\r"

expect -exact "xxxxx\r

Locality Name (eg, city) \[NY\]:"

expect -exact "NY\r

Organization Name (eg, company) \[xxxx\]:"

send -- "xxxx\r"

expect -exact "xxxxx\r

Organizational Unit Name (eg, section) \[\]:"

\r

expect eof

 

Thanks so much for your help!!
