Linux Port Unreachable
All,
I have to servers (NT and REL4).
We can access the application on NT from Linux but we cannot access the applications on Linux when accessed from NT.
The applicaiton is running on Linux with some IP:Port. When we try to access that application from NT, it says that the port is unreachable. How can I open the port in Linux so that I can access the application remotely?
Simple telnet is failing either.
I really appreciate your help..

Or if its easier have one server that monitors the other five and then sends an alert.

OUTB(2) Linux Programmer's Manual OUTB(2)
NAME
outb, outw, outl, outsb, outsw, outsl, inb, inw, inl, insb, insw, insl, outb_p, outw_p, outl_p, inb_p, inw_p, inl_p - port I/O
DESCRIPTION
This family of functions is used to do low-level port input and output. The out* functions do port output, the in* functions do port
input; the b-suffix functions are byte-width and the w-suffix functions word-width; the _p-suffix functions pause until the I/O completes.
They are primarily designed for internal kernel use, but can be used from user space.
You compile with -O or -O2 or similar. The functions are defined as inline macros, and will not be substituted in without optimization
enabled, causing unresolved references at link time.
You use ioperm(2) or alternatively iopl(2) to tell the kernel to allow the user space application to access the I/O ports in question.
Failure to do this will cause the application to receive a segmentation fault.
CONFORMING TO
outb() and friends are hardware-specific. The value argument is passed first and the port argument is passed second, which is the opposite
order from most DOS implementations.
