Script telnet on webserver

Question

Hi

I would like to script telnet to test my website inputs handling. I can do it manually :

telnet localhost 8888
...
GET / HTTP/1.1\n
Host: localhost


...html response

But I can pass command to telnet in my shell script !

I've tried :

(echo "GET / HTTP/1.1\n"; echo "Host: localhost \n\n"; sleep 1) | telnet localhost 8888

It produces no results at all !

Answer 1

(Probably not the only issue) You should "echo -en", and use single quote to close strings. This makes bash interpret \n correctly

Answer 2

I find that netcat, aka nc, is much better suited to this sort of task.

Also as Giuseppe mentions you'll have to fix the quoting. An alternative to bash -e is to quote using $'this form', in which \n, \t, etc. are interpreted by bash when parsing the command line rather than being passed on to echo. So that form is applicable to many different utilities.

Answer 3

The usual answer to "How do I script x?" is "expect"
