But at the "sys_call" level, there's really only one - "mov eax, 102"
- ebx takes the "command", or "subfunction", "SYS_SOCKET",
"SYS_BIND", "SYS_CONNECT", etc. and ecx takes a pointer to
a "parameter structure". The meanings of the parameters differs
depending on which "subfunction" we're doing, but (for some reason)
we recycle the same "structure".

Righto - and there's a dearth of information available on the web
concerning how to make use of the socketcall function at the assembly
level.

If you can find a tutorial on how to do it from C (or other language)
-- it would give you a good start.

I imagine that the process would not be too different from how to do
it in Windows. There is a simple "instant message" example here:

We can use the loop-back address {127.0.0.1} for testing during
development.
