We've run public shell boxes (free web hosting) for 3 years and I didn't get any DoS from such users. Yes, we use jail(8) widely and after logging into system user can't do anything like eggdrops because it is 172.16... net. Just a overlapped jail. So we don't care about amount of processes those users run. BTW if you want to run a shell box you definitly need the patch from PR/18209 (http://www.FreeBSD.org/cgi/query-pr.cgi?pr=18209). *** WBR, Alexey Zakirov (frank@agava.com) To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-isp" in the body of the message
