There is a smal bug in icmpinfo (by Laurent Demailly; available from sunsite): whenever it writes an entry to a log, it first tries to resolve the name.. but if the name-resolve returns an eg. icmp_xxx_unreachable.. than it will perform an name-resolve for that again .. and again .. and again.. this will become a nice logfile-size... bye. adrian.
I'm not sure I'd call that a bug. Icmpinfo logs ICMP; if you tell it to log at a certain verbosity, then it will. From its manpage: -n Avoid name queries - just give IP addresses. (use this option when running unattended on name server hosts (to avoid possible looping)) Also, from the README: IMPORTANT NOTE : *If* you machine is running a named (is a name server) you MUST USE -n when leaving icmpinfo unattended, to avoid some possible looping, when icmpinfo tries to resolve an ip in an unreachable domain. [this problem of domain generated icmps has been worked upon... but I found no satisfary solutions, suggestions welcome, maybe a solution for v1.12 !] If you choose to disregard the info in the documentation, then you experience unexpected behaviour. -Rich -- Rich Lafferty --------------------------------------------------------- IITS/Computing Services | "How should I know if it works?
