Yes.

Nothing really special on the FreeBSD side though. Just an alias 
address on one of the NIC's.

Motherboard with console redirection

[Javier Henderson]

Greetings,

I'm looking for recommendations for motherboards that sport serial console 
redirection, which are known to work well with FreeBSD. I don't have a 
processor religion, and relatively modest needs: a few SATA ports, preferably 
built-in video (for the initial setup), at least one IDE channel, support for 
at least 2GB of RAM and one processor slot (or two, if it will work with a 
single processor). Built-in gigabit Ethernet would be nice.

Thanks.

Auto-negotiation will work only if the other end (ie, the switch) is set to 
auto-negotiate. Otherwise the FreeBSD host will set itself to half duplex.

Add a few more servers, for example reloj.kjsl.com (I run it).

Also add:

server 127.127.1.0
fudge 127.127.1.0 stratum 4

It should improve the clock stability while you're not connected to the

Can SSH clients on your local network connect to your system?

You say packets are arriving at your machine, can you elaborate on this 
further? Assuming a SYN packet arrives from a host, so you see a 
SYN+ACK go out, etc?

Re: FreeBSD Torrent Server

[Javier Henderson]

What, exactly, is the benefit to an ISP to wear such a feather?


Mainly marketing, if the ISP can handle hosting of freebsd.org, then
they obviously can handle hosting of most other things on the  
Internet.


Remember, the people that buy seriously large amounts of bandwidth
don't use television commercials to make decisions on providers.  They
use tools like whois to see who is hosting major sites then go talk to
those people.

It also isn't a bad thing to be the landlord if the provider  
happens to have

a
lot of FreeBSD in use themselves, I'm sure it helps get developer  
attention

to
problems rather quickly.  Have you ever seen a post from anyone at
Yahoo with a problem with one of their FreeBSD servers?


Marketing, yes, but you may be overstating your case. The bandwidth  
and power aren't free, and the ROI on the expense of providing that  
might not be enough. Plus, it's not just ISP's hosting servers, many  
are hosted by companies and colleges.

I've FreeBSD systems running 4.10-RELEASE, 5.5-RELEASE and 6.1-

Note that if you force the FreeBSD system to a fixed setting, and  
leave the other side (your 3640 in this case) to auto negotiate, then  
the auto negotiating side will set itself to half duplex. However, if  
you set both to full duplex, then collisions should not occur.

FreeBSD 6.x problems with IDE drives

[Javier Henderson]

Greetings,

I've a motherboard and disk drive that have been running on older
versions of FreeBSD for quite a while, reliably. Recently, I moved to
FreeBSD 6.0-RELEASE (and lately to 6.1-RELEASE, but it didn't help),
and the system periodically shows:

> ad4: FAILURE - device detached

This is likely to happen under heavy I/O load (the machine serves a
few dozen virtual websites, averaging 15 Mb/s sustained).

Then the machine will eventually reboot.

The motherboard is an MSI with an AMD 1.3 GHz CPU and 1.25GB of RAM,
it has two IDE controllers, a VIA 8235, and a Promise (I can't access
the machine right now to get the exact model number). The problem
happens the same with either controller. I tried both UDMA100 and PIO4
modes, no difference.

SMART reports a healthy drive, and as mentioned before, it didn't have
problems with older versions of FreeBSD (5.4-RELEASE to be precise)
and under similarly heavy load.

The IDE cable was replaced, just in case, but again, no difference.

Any ideas?
