    Hi Folks,

    Would appreciate a hand here:

    I am trying to automate a hit to a webserver on our LAN, and use the results to send an email to a specified person. The problem is that I can only get the output from the page when I run a telnet manually. If I try to automate it, the results do not appear.

    This is what I am doing at the moment:
    [me@server]echo "get /MyPage.asp" | telnet MyWebserver 80
Trying <the ip address>
Connected to MyWebserver
Escape character is '^]'.
Connection closed by foreign host.

    I know that the page is being hit properly, it's just that the results are not being captured. For instance, if I do it manually the results are outputted as expected.
    [me@server] $ telnet MyWebserver 80
    Trying <the ip address>
    Connected to MyWebserver
    Escape character is '^]'.
    get /MyPage.asp
    HTTP/1.1 200 OK
    Server: Microsoft-IIS/4.0
    Date: Mon, 10 Oct 2005 14:15:40 GMT
    Content-Type: text/html
    Set-Cookie: ASPSESSIONIDQQQGGQEX=FJGQMOPZDAIFCFLGIFOMIOKK; path=/
    Cache-control: private

    Name :
    Phone :
    Email :
    Connection closed by foreign host.

    Any tips would be appreciated...

    Do you really need to use telnet ? It is an awkward kludge - why not use
    one of a buch of existing utilies such as wget, curl, GET etc ?
    Any tips would be appreciated...

    Here is two:
    Methylated spirits is very useful for removing grease stains from glass.
    Include the OS that you are using when asking questions on the Unix
    board.

    That would be the preferred option, but they are not installed on the server and our sysadmins are very slow to install extra utilities.

    Don't eat yellow snow is another handy one...

    It's Solaris 8.

    A colleague of mine actually sorted it out. If you put the commands into a shell script like so: 
    #!/bin/sh
echo open MyWebserver 80
sleep 1
echo get /MyPage.asp
sleep 1
echo exit

    and run it like this: 
    ./myScript.sh | telnet

    The output is captured...

    Thanks anyway for the response.
