-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I block pings on my server, and for a reason. Ping is one of the biggest tell-alls about a network. No outside entity should ever need to ping me, & my own machine has no real reason to ping itself, either.
Try this: ping first.three.octets.255 & see what happens. It will return every machine attached to that network. I don't want the gomers to have such an easy time finding who's attached. & for you gomers who're lurking this list... :P - -Tom - -----Original Message----- From: Edward Dekkers [mailto:[EMAIL PROTECTED]] Sent: Sunday, February 09, 2003 9:06 PM To: [EMAIL PROTECTED] Subject: Re: Can't ping myself. > Any other good idea ? > > Thanks alot! > > Lei Use an iptables firewall script, but don't run it so tight. Learn a little about iptables and roll your own. Jeez - even Monmotha's script doesn't even let me ping the server from a client I found out the other day. Just a side-note to everyone else: I realise there's things like ping-floods, DOS attacks etc. etc. etc. and we have to protect against them, but most users would choose an intermediate or high firewall setting when they set up their boxes. Both these block ICMP requests. A lot of users are running ping to test network connectivity. Is there any way to get around this problem? Surely the default firewall set-up could be set up to allow ICMP request from the internal interface, just not forward those from the external? Sorry if I sound naive. Firewalls are not my strong point, but I know I find myself sighing every time I'm testing connectivity on a Linux network, and I have to turn off the user's firewall just to test with ping. Invariably I always forget.
