Hi all,

I have a new computer with Windows XP home and NIS 2003 with all the
latest updates. I have three networking problems:

1. No-one seems to be able to ping my PC with NIS enabled or disabled

2. With NIS enabled I cannot even ping my own PC using the dynamically
allocated IP address from ADSL

3. I can access my Linux server from anywhere around the world except my own
PC next to it:
(a) Ping does not work
(b) ftp would quit saying "Connection closed by remote host"

What is going on? Someone suggest XP Home does not properly support
networking. Is it necessary that I have to pay to upgrade to XP
professional?

Any comments or suggestions greatly appreciated.

Regards,
lc

Thanks Bee. I tried but same problem. I then looked at NIS and found it has
a rule blocking all
ICMP connections. If I permit ICMP then I can ping myself.

I am trying to connect my PC to my server and this seems a step in the right
direction for me. Thanks!
I have two further questions:

1. Is it safe to allow all ICMP connections to/from my computer?
o Actually I found I can just enable echo request 8 and it works fine. So I
suppose I should not permit all ICMP connections
2. Even if I allow all ICMP connections I still cannot ping my PC from the
server. What may be wrong there

Thx!

Any overview of ICMP is also appreciated.

You can get a taste of ICMP with the three helpings in Suggested Topics in
the Search result (accessed from the Help and Support window). Note in
Enable Internet Control Message Protocol, it says "If you enable ICMP
options, your network can become visible to the Internet and vulnerable to
intrusions." Further reading can be obtained from
http://www.ietf.org/rfc/rfc0792.txt?number=792

My knowledge in this area is rarefied. Maybe someone more knowledgeable
than I can be of assistance. If you don't get any more help from here, may
I suggest you post this to:
