I'm set max. processes count (using "ulimit -u") in sendmail start script
(right before first (parent to others) daemon is executed) and in sendmail
config file ("MaxDaemonChildren" parameter). And so on for all other daemons.
Summary, if all services runs max. available children count, there is some
available processes (total running processes count lesser than max. available
processes) and free virtual memory for run some sshd and shells to log on. I
think, there is no need to change kernel data structures.
P.S. Excuse me for my ugly English. :)

I'm redirecting some outgoing traffic (with dest. ports 80:81 and so on to squid and with dest. ports 20:21 to frox) via firewall and using squid with delay_pools + frox with redirecting traffic to squid (where it goes through delay_pools). One moment - frox seems to be unstable. -- With Best Regards, Denis A. Kulgeyko DK666-UANIC e-mail: [EMAIL PROTECTED] ICQ: 81607525 SMS: [EMAIL PROTECTED] -- UNIXes ... they are VERY friendly.
