Cannot ping Fedora 7 from other machines


Hi,

I just installed Fedora 7 (with firewall disabled) and got its IP address assigned as 192.168.122.1.

What I found out is this Fedora 7 can ping other machines.
But my other machine canot ping this Fedora 7.

Can some one explain to me why this is happening?

Thank you!

Philip

You do know that fedora 7 has been unsupported for almost a year now ( End of Life was June 2008 ) , and that fedora 10 is the current and fedora 11 will be out in about 1 month

It's probably just your firewall settings.

ping requires icmp access. See http://www.cyberciti.biz/tips/linux-...icmp-ping.html if you aren't using the gui firewall interface

Hi to billymayday,
Thanks for giving the link to iptables which has command lines for ping.

A friend of mine told me to try "/sbin/iptables -F" which will do clean up.
But I am hesitate to do taht - because I really don't know what I am doing.

Hi to John VV,

Thank you for reminding me that Fedora 7 is out of date.
I am just playing with it. Can I update the system to Fedora 10 on-line
and do it automatacally?

7 to 10 or 11 . The answer is no to an update .Do a fresh install of fedora 10 or 11 ( in a month)

there are WAY to many changes in fedora 8, 9 and 10 for that to work reasonably well . It might but i would put it at 95% chance of a fubar'ed computer .

Doing a fresh install is also the recommended method

Hi John VV,

Yes. Do a fresh installation make sense (because people are saling Linux CDs).

Thanks.

flushing iptables just clears the rules. Do you really want a firewall-less system?

Since you guys are really nice, I want to ask more questions:

To John VV:
I buy Linux CDs to save me some time. Because I am sure I can use the CD to start the installation process. However, the LQ download is too complicated because there are so many choices to make: torrent, live.iso, DVD.iso, ...
What is "torrent" means? What Do I need for?
What is "live.iso"? If I just want to install a plan Linux server, can I use live.iso to install? Sorry for these basic questions.

Philip


To billymayday:
At this time I really don't care about firewall. My goal is to later integrate some wiki software with my web documents. I need other machines to be able to maccess this experimental Fedora server.

I did flushing yesterday and still cannot ping.

I also follow the following recommendation (from your link) and still cannot ping:

SERVER_IP="192.168.122.1"
iptables -A INOUT -p icmp --icmp-type 8 -s 0/0 -d $SERVER_IP -m state --state NEW,ESTABLISHED,RELATED -j ACCEPT

iptables -A OUTPUT -p icmp --icmp 0 -s $SERVER_IP -d 0/0 -m state --state ESTABLISHED,RELATED -j ACCEPT

My next choice is to reinstall for Fedora 10.

Thank you!

Philip
