The following reply was made to PR sparc64/105157; it has been noted by GNATS. From: js <js@fireball.qxni.com> To: bug-followup@FreeBSD.org, andrew@grillet.co.uk Cc: Subject: Re: sparc64/105157: No reply to ping on Sparc64 Date: Sat, 21 Jul 2007 00:56:32 -0500 (CDT) Andrew, I run 6.2-RELEASE on an Ultra60 (2-way SMP), with nfsd running although not actively serving any NFS clients. I am also not running Apache, as you are. I am able to ping this machine (I receive an ICMP_ECHOREPLY [id=0] packet back corresponding to each ICMP_ECHO [id=8] packet I send to the machine.) Are you familiar with ddb and kernel debugging at all? If so, find out exactly what the kernel is doing with those ICMP_ECHO packets. They would be stored in mbufs by the kernel after the NIC DMAs them into main memory. Watch those mbufs during breakpoints on various network functions. If I were you, I would start by setting breakpoints on ip_input() and icmp_input(). Regards, Jon
