I usually use look at /usr/include/netinet/ip_icmp.h for a quick reference e.g. #define ICMP_UNREACH 3 /* dest unreachable, codes: */ #define ICMP_UNREACH_NET 0 /* bad net */ #define ICMP_UNREACH_HOST 1 /* bad host */ #define ICMP_UNREACH_PROTOCOL 2 /* bad protocol */ #define ICMP_UNREACH_PORT 3 /* bad port */ #define ICMP_UNREACH_NEEDFRAG 4 /* IP_DF caused drop */ #define ICMP_UNREACH_SRCFAIL 5 /* src route failed */ #define ICMP_UNREACH_NET_UNKNOWN 6 /* unknown net */ #define ICMP_UNREACH_HOST_UNKNOWN 7 /* unknown host */ #define ICMP_UNREACH_ISOLATED 8 /* src host isolated */ #define ICMP_UNREACH_NET_PROHIB 9 /* prohibited access */ #define ICMP_UNREACH_HOST_PROHIB 10 /* ditto */ #define ICMP_UNREACH_TOSNET 11 /* bad tos for net */ #define ICMP_UNREACH_TOSHOST 12 /* bad tos for host */ #define ICMP_UNREACH_FILTER_PROHIB 13 /* admin prohib */ #define ICMP_UNREACH_HOST_PRECEDENCE 14 /* host prec vio. */ #define ICMP_UNREACH_PRECEDENCE_CUTOFF 15 /* prec cutoff */ For a complete description, I imagine the relavant RFC or some of the TCP/IP illustrated books for more info. ---Mike ------------------------------------------------------------------------ Mike Tancsa, tel +1 519 651 3400 Network Administrator, mike@sentex.net Sentex Communications www.sentex.net Cambridge, Ontario Canada To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-security" in the body of the message
