Your comments about yp servers set off an alarm bell in my head, and I
have a sad and salutary story to tell. A few weeks ago, some fuckwit
mailbombed me (I received over 3,000 obscene messages telling me what to
do with my mother!), and it prompted me to install an anti-spam program on
my system. Along the way (I installed that correctly at least as it turns
out), I discovered the identd daemon wasn't working properly because
hosts.deny/hosts.allow weren't configured properly and I did fix this.
However along the way, I also made two mistakes, both these errors
together caused the icmp (and also sunrpc) problems. In my wisdom, I made
the error of thinking dnsdomainname set the machine's domain name (i.e
tahallah.demon.co.uk). As it turns out it is not what I thought it was! At
that point, I made the second mistake, whch was to type in 'domainname'
instead of 'dnsdomainname' (which would have almost certainly told me that
this wasn't what I was trying to do!). As domainname is for yp servers,
this caused both the sunrpc & icmp problems I had experienced. Removing
domainname cured all these problems.

Gaaah. I need to go put my head down the nearest toilet or something. At
least I can laugh now that I've solved this.

Cheers,
Alex
