So, I guess this problem is related to TCP stack, rather than to an OS. Tony and Byung suggested good ideas to check out, but it seems that the problem is "smart" enough. First, some notes about my situation: 1. All noticed symptoms are the same. 2. PING works fine (both via IP-addr and via DNS-name). 3. No firewalls of any matter (LAN access) 4. No problems with /etc/services, /etc/protocols and /etc/inetd.conf 5. Routing table is good (and quite simple). 6. All interfaces are ok. 7. I can't type on keyboard, but can switch VC (but can't type there again) and can do soft reboot (handled by keyboard driver). BUT ... (unbelievable) 1. Just after reboot *everything* is ok. Nothing in syslog. Filesystem is ok. 2. After a not so long time situation occurs again. 3. Reboot again and it is fine again ... After a hard time of guessing what the hell is going on, without any chance to analize anything :-(, I found only one bad thing - there was no "localhost" definition in DNS zone (/etc/hosts was not used by resolver). I would be agreed that the problem was related to this missed definition, but why my system ever worked for some (*long*) time before? Situation was happened after Apache 1.1.3 was installed (there was no problems with 1.1b and another kind of problems with 1.2b4 and b7). The software running on that system (except for OS) was: syslogd inetd (listening to FTP, TELNET, POP3 and IMAP4) sendmail 8.6.12 Apache 1.1.3 Hey, BSD networking gurus, have you any ideas what *may* be wrong to lead to such weird situation?
