Re: [suse-security] ipchains: unknown ICMP requests ...

Hi there,

we're using ipchains as firewall. Everything seems to be fine, but now and then, we're getting ICMP requests (PROTO=1) from low ports (1-8) to our webservers at ports 0 or 1. I can't figure out, what's the matter with this requests, it doesn't seem to hurt anyone, that the requests are blocked by our firewall. Is there any intelligent DENY-rule for this sort of requests ?

Looks like an ordinary ping to your web server (at least from port 8 to port 0). juri -- juri.haberland@innominate.de system engineer innominate AG clustering & security networking people phone: +49-30-308806-45 fax: -77 web: http://innominate.de
