I am weirdly unable to make any connections (tcp, udp, icmp) to the machine and am hoping someone has some off-the-cuff ideas. I violated rule #1 (don't sysadmin while tired) and somehow nuked my ipfw configuration while attempting to set up NAT via OpenVPN (using IPDIVERT in my kernel build). I rebuilt it from memory, but since then, I cannot connect to the machine at all. I do not believe that it is ipfw related. I've tried enabling/disabling ipfw via sysctl and /etc/rc.conf. I've flushed all rules, as well as installed an entirely open ruleset. I've re-built and booted into a kernel with all IPFIREWALL-related options (including IPDIVERT) commented out. While I had denyhosts installed, it's disabled. I've tried single user mode with networking enabled. The system boots fine. It NFS-mounts network drives without problem. Default gateway and network configuration look fine, it can ping and connect to both LAN and Internet addresses. tcpdump sees incoming connections, but no replies. Inetd is running. From the system console itself, I can telnet to all ports on its IP. Syslog tells me nothing. No console messages. I'm missing something utterly fundamentally idiotically harebrained and I have no clue what it could be - I'd be endlessly grateful for any tips or ideas on what to try (beyond an exorcist). Thanks! -John -- John Morgan Salomon john - at - zog.net www.zog.net
