Hello,
please, don't stop reading. :-)
After upgrading my PC [1] at home from 2.1.0 to 2.1.5 I had severel problems.
(I chose the `Upgrade' option from the install menu, medium CD.)
I hope, at least one of you can comment on it or suggest some work-around
to one or another point.
>>> INSTALL
1) Already during the install [2] I received some messages about `junk' and
`skipping' (I switched to vty2 a bit late).
After editing my /etc-files (yes, I had saved my old sysconfig somewhere
else) in the shell on vty2, I typed `reboot' and got (after sync)
a panic on `dangling vnode'.
In the following reboot I noticed several unreferenced inodes on /usr [3].
However, I got no lost+found and the files are gone.
How can I convince fsck on reboot to create lost+found and save the
unreferenced files (esp. when no one is at the console) rather than
discarding them ?
1a) After trying to use cc1plus I noticed that /usr/libexec still contained
my 2.1.0 files and /usr/sbin/* and /usr/mdec/* had the correct dates
but did not compare with /cdrom/dists/bin/bin.??
(Notice that cc1plus ... /usr/sbin are in bin.bx ... bin.cb (rf. 1 ?))
(Yes, after install I could read bin.?? without errors several times)
>>> X11
2) Several times it happened (also on 2.1.0 and on different machines)
that after some uptime or by killing the Xserver from the text console,
one cannot switch back from X (xdm running and restarting X) to a text
terminal (sth. like `VTactivate failed').
Is there a way out without booting the system ?
>>> SCSI
3) Is anybody working on completing the SCSI-CDROM driver as descibed in
cd(4) (i.e. ioctls CDIOCCAPABILITY or CDIOCCLOSE) ?
4) Is there some command around to _retention_ QIC tapes (on SCSI streamers)
(AKA `mt retension') or to reset the driver (to read the tape again
after "unloading" (mt rewoffl) without the need to eject and insert
the tape) ? (In both cases SCSI-command LOAD/UNLOAD is invloved.)
(I have the OEM manual for 5525ES and 51000ES (SCSI1&2) at hand.)
>>> DNS
5) Recently, I noticed that netscape (BSDI-3.0, 3.0b4, 3.0b5), but also ftp
and traceroute, fail on resolving hostnames. They return very quickly
with 'host has no DNS entry'. The second try is usually successful.
Named runs on a 2.1.0 machine and the problems occur on 2.0, 2.1.0
(also the server itself) and 2.1.5 machines.
This is true for first-time and very-remote queries as for local ones
(without entries in /etc/hosts).
Any idea, where to look at ?
>>> MISC.
6) Just want to mention that vi does not respect `noautoindent', esp. on
`replace' (compared to the various vis on different systems that I have
access to).
7) Is there a way to have lpq show the status of _all_ avail. printers
at once (like lpstat) ?
8) As a final question, where should read(2) on /dev/rcd0c continue after
0x8028 = lseek( fd, 0x8028, SEEK_SET) ? (left as an exercise :-)
I relied on the return value (0x8028), but it actually starts at 0x8000 !
But, why ?
(Wouldn't life be much easier, if one could read arbitrary buffer sizes
and seek arbitrary offsets ?)
9) As a more final question, has anyone a solution to dynamically add/remove
users on an FreeBSD server.
Accounts are merely needed for authentication and print accounting and
are administered in the computer center, except for local, static ones.
(no NIS)
Nevertheless, let me finish with that I'm still happy with FreeBSD.
(Otherwise I would install ...... yes, what ? :-)
Thanks,
Robert
