Hi, FreeBSD team ! I've installed FreeBSD-2.0 ( then 2.0-950210-SNAP ) on following configurations: I found the following: 1. slattach ----------- it want not call "-u" configure network script on startup if modem is already online and gives CD on. I make some correction to avoid this, it is in file "slattach.patch" ( all files are attached below ) 2. mountd --------- it gives up on startup with "Memory fault - core dumped" on sertain configurations of /etc/netgroup, below is one example in files "exports" & "netgroup". The problem seems to be in empty host component in triples ( <host>, <user>, <domain> ), although according to man every component may be empty "wildcard". Maybe, I'm doing something wrong ? Also, it seems to be better avoid terrible "Can't open /var/db/mountdtab" - just let mountd to create this silently :). 3. named -------- it fails permanently on zone transfer for some particular zones (untill these zones are not changed in some way ). Situation details: one server(secondary) transfer zones from another; both run FreeBSD-2.0 with indentical named; all zones exept two of them are transferred OK; these two are transferring too, but at the end of each transfer named-xfer logs something like: "recv(len=7) n=0 && !errno" and zone file, eventually, is not created. It should be noted that since 2.0-950210 installation I havn't saw this situation; but, maybe, this is due to "good" zones ? :. KERNEL ( or whatever it was ...? ) It took about a month to investigate some strange kind of problem, and I have no idea what is a real matter up to now. The problem was in frequent ( sometimes with 3-10 min delay ) rebooting of host with the result is the sames well - about a week ) - as somebody press "Reset" button... Sometimes it was "Page fault", and sometimes - "Privileged instruction", but most frequent - without any words ... Hardware: Unkn. i386DX40, 8RAM, SVGA, 120M IDE ( Seagate ); sl0 - standard COM1 - 57600, ext. modem 19200 4W L.L., slattach sl1 - standard COM2 - 38400, ext. modem 14400 2W L.L., slattach sl3 - COM3, irq 5 - 38400, int. modem 14400 dial-in, pppd sl4 - port 300, irq 9 ( multi 8-com-port card, ARNET-8 compat., configured as not having AST Master Int. Reg. - really it has, but at different address ) - 38400, ext. modem 14400 2W L.L., slattach Daemons: inetd syslogd named mountd -n sendmail routed -g -s rwhod 8 virt. cons. I tried to change all and everything in hardware: motherboard Cyrix 486DLC40, 8RAM; another system block with 486DX40, to exclude possible power supply problems + using UPS removing all internal cards ( 8-ports, int. modem ) So, I can't think it is hardware problem. But...the result is the same I tried to reduce COM-port speeds ( to 38400, 19200, 19200... ) I tried to reinstall system several times, giving different swap area - 16M, 24M, 32M. I tried to limit processor support in config - to only i486. It seems that crash follows some network activity - sometimes, immediately after starting FTP, for ex. Please, let me know if You have some ideas - what it may be ? What should I try to do ? ( I'm not a kernel debuggist, sorry...:) ) Now I'm thinking about FreeBSD viruses, or some kind of ICMP packets that are designed to reboot computers and visa versa... ;) Thank You much for reading my story, ----------------------------------+------------------- With respect, Serge E.
