My firewall has a specific filter to allow/disallow pings. I thought that was fairly common.
I can't interpret this very well but if I disallow outbound ping I get 03/28/05 16:37 firewalld[140]: deny out eth1:0 60 icmp 20 128 ---------- 24.225.231.115 8 0 (Ping) Note: --------- private internal ip from the firewall log. A denied inbound smtp looks like 03/28/05 16:35 firewalld[140]: deny in eth0:0 48 tcp 20 110 218.18.139.150 65.41.81.185 37143 25 syn (SMTP) briefly those fields are: date time process disposition direction interface length protocol (seem ping uses its own icmp) ip header length time to live source addr dest addr source port dest port (rule ) If this doesn't help, maybe someone else can do better than me. Given it's got its own protocol, I'm not sure ports even have meaning. bp -----Original Message----- From: Juan Jose Costello Levien [mailto:[EMAIL PROTECTED] Sent: Monday, March 28, 2005 3:53 PM To: James Users List Subject: Re: Cannot receive email in my james server (I can send ok) Clive, Thanks for your answer. My hostname is jcostello.ath.cx. (ath.cx is from DynDNS). I am not sure if someone can ping my machine, because I have a firewall and I dont know which port is for ping. I opened port 7 and nothing. But the telnet connection is working, so you can try: telnet jcostello.ath.cx 25 and should work. Yes, I remember I saw a trick for the problem. Well, lets continue reading. Thanks.
