Hey all... I tried sending this earlier... accidentally sent it to
[EMAIL PROTECTED], then tried bouncing it to the write address...
anyway, apologies if it didn't work correctly.
Anyhoo...
I'm trying to get a piece of information from a server in the field that
responds to a certain command with a line of data... ie 'telnet machine
temp' and it gives back "MACHINE:75.3" (temperature).
Anyway, there's a bunch of other stuff you can do to it with rsh, but
that's not directly important. I'm trying to build a web interface to
control these machines. Basically, I need to have PHP call 'telnet
machine temp' and have it feed out whatever the machine returns...
I've tried exec(), system(), passthru(), and backticks, all without
success. I imagine that the reason for this is that telnet isn't routing
it's stuff to STDOUT (or whatever it is that php reads from in this
situation).
Now, get this. If I use my php binary (shell scripting with php! wh00!)
it works dandy... the temp gets passed on, yadda yadda yippy. But the
second you try from a web browser, no dice.
Now, I may be completely off track here... it may be that for some reason
that I don't understand, telnet isn't actually outputting anything... I
suspect it is, though.
So... any ideas how I can get what I want?
Thanks,
Ben
