The system call you just made (read(), write(), ...) set
errno to EINTR and returned -1. It is telling you that it
failed because it was interrupted by a signal.

My machine is a DNS consumer, the rest of the network is Windows NT. We have
Internet Access (routing) and a Nameserver.

Problem is, what is my Domain? I have a windows LAN with internet access but no
specific domain. The Webserver is external. (sorry if this sounds dumb, but I am
new to Linux and networking development) - but I'm working at it.
As I said, network is Windows NT and I am going to need SMB, which worked fine
off my Harddisk, but since my stripped System is on Disk on Chip, Name
resolution failed (SMB as well, probably caused by the DNS Problems) what works
fine is ping by IP address. Using my hard disk and pinging the Win NT server,
Name Resolution called it SERVER (Its windows Host name).

OK, not that new ;-)

so what do I put as my Domain ....

OK, in /lib I find libresolv.so.2, libnss_dns.so.1, I guess they are the

read() and write() return the amount of characters processed. If this
is less than the amount requested, the call may have been interupted.

open(2) and read(2). On /proc/cpuinfo and /proc/meminfo, that is.

Crossposted-To: comp.os.linux.development.apps
Theoretically you shouldn't be able to modify any of it. The first four digits are the
ID of the cards manufacturer. (ie 3COM, IBM etc... - Each manufacturer may have more
than one ID) The second set of four digits are assigned by the manufacturer
(generally in
sequence) to give each card a unique ID. (ie every network card ever manufactured
should have a unique id). Some cheap NIC manufacturers allowed the last four digits
to be
changed by their configuration software. If you have one of these then you should be
able
to read the NIC's (BIOS?) configuration, change the last four digits and write it
back.
What I can't understand is why you would want to change the MAC address for anyway.
If two or more cards chare the same mac address your network won't work anyway.
Hope this helps.
Cheers
