RE: rj-45 connector

[Joseph H. Fry]

Look it up on the web... There are many many sites with good
illustrations and such.

Keep in mind that most people use the 568b standards.

Just google for 568b wiring and one of the first few sites will probably
be readable by you.

 Subject: rj-45 connector


 dear sir,
 i've 3 computers and  i want to connect  them togather as a
 workgroup network via a hub. i know that the both ends of
 cable must have the same sequense of color .please advice me
 if that the color sequence of wires connected to rj-45
 connector is important or not?..i mean, in another word, is
 there a special sequense of color ? or any sequense of color
 will be valid when the both ends have the same color sequense
 ? i wish that response will come on soonbest regards

Slow writes using hardware ata raid on older server

[Joseph H. Fry]

I've finally got a clean updated stable FreeBSD box, thank you all who
have invested your time creating documentation that makes it so easy for
us newbies.

Anyway, I had gentoo on the machine for about 10 minutes... Had a
problem with writing to my Megaraid i4 controller... It was terribly
slow (1MB/sec)!  So I figured I'd try FreeBSD and see how that goes.
I'm no expert, but as far as I can tell Bonnie output (below), things
are not much better.

I only tested with a 100MB file ($ bonnie++ -s 100) because I need to
head to work and didn't want to wait for it to go through a whole 1-2GB
file.

Also below you will find the output from top while bonnie++ was writing
a byte at a time and writing intelligently.  I only include these
because I'm not sure how to read them properly for multiple processors.
From what I can tell, during the byte at a time write the processor is
pegged, but only about 1/4 used during the intelligent write.

Anyway, I'm stuck now with no idea what to do to fix this problem!  Any
guidance would be appreciated.  (expecially help understanding what the
different values in the bonnie++ output mean)

System:
 Dual PII 233 (smp in kernel) on intel server board
 128MB ECC SDRAM
 LSI MegaRaid i4 ATA RAID Controller (uses amr) in pci slot 1
 Onboard Intel e100PRO
 3Com 3c595
 Adaptec SCSI controller onboard, and one in pci slot
 (I don't have the cable I need to connect my CDROM to
the onboard SCSI controller so I added one temporarily)

RE: First questions: rebuilding world

[Joseph H. Fry]

  Also, does doing all of this bring me to the most recent stable
  release? (I noticed that 5.3 was released yesterday,
 presumably just
  after I downloaded 5.2.1).

 If you've used the correct TAG in your cvsup files and have
 cvsup'd over the last day or so, then you should build 5.3-RELEASE.


Which tag is the correct tag?

RE: re bittorrent

[Joseph H. Fry]

Not to mention, if there are enough clients hosting, then downloads can
often be faster.

Why?  Because partial downloads can be pulled from multiple sources.

I just downloaded the miniinst iso in under 15min at an average rate of
about 360KB/s from a pool of 10 servents (bittorrent server/clients).
The only way I could get it that fast with FTP is if I used getright or
someother ftp client that allows for splitting a download across
multiple FTP servers.

Now of course the real benefit comes just after a release when everyone
and their uncle is downloading a copy and the FTP servers are extra
busy.  When things slow down a bit it's not as big a benefit.

  Why do you download with bittorrent as opposed to FTP?

RE: First questions: rebuilding world

[Joseph H. Fry]

 Once in single user mode, ssh is out of the question.  In single user
 mode, only
 *person* can login, and that is at the actual terminal.
 Depending on the situation, for example.  My firewall is at the other
 side of the
 house, without a keyboard/monitor.
 Since the box doesn't have any other logged in users, I
 normally build world in multi user mode. Doing so is taking a
 chance with the success of the build world, but like I said,
 it depends on the situation...

Thanks!  So you can do everything in multiuser mode, or do you still
have to drop to single user mode to actually install the new kernel and
new system binaries?

Also, does doing all of this bring me to the most recent stable release?
(I noticed that 5.3 was released yesterday, presumably just after I
downloaded 5.2.1).

Thanks again,
