Updated packages certainly do exist on the FTP servers but I can't see how to access them from sysinstall. Learning how to use pkg_add(1) (which can reach the parts of ftp.freebsd.org that sysinstall apparently cannot) is probably your best bet.

Many - I would guess most - do, at least to the extent of requiring the same major version (e.g. 5.x). There are 63 instances of USE_PERL5 in ports/textproc alone. I'm not a major direct Perl user, but I remember the jumps from 5.0 to 5.6 and from 5.6 to 5.8.

3ware array access lock up on 7.1-RC
I am not even sure that it is related to freebsd, but maybe someone could point out the problem. We wanted to upgrade our hosting server from FreeBSD 6.2, 3ware 8506-4LP SATA RAID, raid 5 to FreeBSD 7.1 (RC for now), 9550SXU-4LP, raid 10 We have tested the new installation on ASUS P5K WS motherboard with PCI-X slot while the server kept running. The server has Supermicro X5DPE-G2 (pretty old one, 2004). So, when everything was ready, i just took out the old controller and disks and installed the new controller and the array disks. The system booted up, but when i started very intense file operations the file system just froze. The weird thing is that any open program which does not use filesystem kept running fine. For example, i could type and edit in open ee editor, but copying progress bar in midnight commander just stood still. If i tried to save file or open file or do anything disk related from ee in another console the program froze too, apparently waiting for disk system to reply forever (i tried waiting for 20 minutes). I could even connect to ssh port, but it does not auth because sshd needs to read something from the disk. I put everything back into Asus P5K WS and tested it. Everything worked fine again.

Having issues with the nvidia driver on my box

So, I installed the driver and although things are working I'm getting this on console 0: NVRM: AGP cannot be enabled on this combination of the amd CPU and OS kernel NVRM: kernel upgrade recommended So, when I installed the nvidia driver I said to enable AGP. (Figuring only that this is an AGP board, why not?) My graphical environment works but I'd like to resolve this. Also, I think that some little quirks in my display can be attributed to this, but I'm not sure. Is there some sort of kernel option I must include and build my own kernel? Thanks, Andy ps in case it matters, my board is rather old. I purchased it 4 years ago and as I'm not a gamer, it suffices quite nicely.

[2] http://en.wikipedia.org/wiki/Md5#Vulnerability
the problem is that there are several thousands of these files
with dos names and an embedded '\;'7 in the file names. the
shell gets in the way. i have tried
sprintf(cmdbuf, /usr/bin/cmp %s %s, orig, new);
system(cmdbuf);
chokes on the embedded bytes.
i'm thinking of using
find . -name * -print -exec {} \;
and let me program select out the file suffix. i unlink the
screwy dos-ish filename. that's why i want to be sure the
copied/renamed files are right.

You don't need a prefab `cmp' function, because the base system already
includes tools that can help:
(a) The `cmp' utility:
cmp file1 file2 ; echo $?
(b) Checksum tools like `md5', `sha1' and `sha256':
md5 file1 file2
sha1 file1 file2
sha256 file1 file2
You can then compare the file checksums. If both the md5 and
sha256 checksums are identical, then the files are the same[1].
[1] There is a possibility of ``checksum collisions'', especially
with md5 (see [2] for more details). But if you use two or
more checksum types and none of them show differences, the
odds of a collision are small enough for most practical
purposes.

Your problem there is just normal file globbing. If you quote the names
just like you would on the command line (modulo escaping for C's special
characters), it should work fine.

For a single file, you could use some kind of checksum in your program or externally, but in general it will be comparing against the cache of the file's buffers, not against what is really on disk, so if you suspect an operating system or hardware-write bug, you won't spot it immediately.

Use quoting (and snprintf() because it supports range-checks for the
buffer you are passing to it):
snprintf(cmdbuf, sizeof(cmdbuf), cmp \%s\ \%s\, orig, new);

strange fsck results
I am running FreeBSD 6.3 as a VMware virtual server and am getting some strange results when I run fsck. When I run it in multi-user mode I get quite a few UNREF FILE errors but when I switch to single user mode fsck does not find any errors. Is this something I need to worry about and if it is how might I try to get fsck to repair them?

Bad copies caused by bugs in your software, or bad copies caused by bugs in FreeBSD? Or problems with your hardware? Once you know what you're after, you can start figuring out how to get it.

Is this something I need to worry about and if it is how might I try to get fsck to repair them? When you run fsck in multi-user mode, are you running it on a mounted filesystem? In that case, those errors would be perfectly normal, since the kernel will typically have several file handles open on each filesystem it mounts. -- Lowell Gilbert, embedded/networking software engineer, Boston area http://be-well.ilk.org/~lowell/ ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org

A forceful repair might be required. see the fsck manpage. A forceful repair may cause more damage than help, which is part of the reason the multiboot process just preens it.
