In /etc/rc.conf, the variable $hostname sets the machine's name at
startup.  Simply edit the value set here, and next time the machine
starts up, the new hostname will be set.

To change it in a running system without rebooting, use hostname(1):

# hostname new.machine.name

Re: Setting up network

Hello all,
While we are on the topic, after the hostname and domain have been 
setup from the initial installation, how can they be changed? I went 
through the FreeBSD manual and some Google searching and did not come 
up with anything that made any sense. I assume there are files to be 
edited, probably under /etc. I am just not sure what all of them are. 
Any assistance (or reference to a site that will explain this to me) 
will be greatly appreciated (I am a newbie to UNIX and especially 
FreeBSD).

Regards,
Anthony

I would just add that on your internal network you may literally use any 
valid name. I have an office network and several of the boxes run apache, 
providing me with a web development environment. But I have a self made 
rule of not naming my websites anything which is legal on the WWW.

Because you can create your own yahoo.com on your network, but the problem 
is that if you create thisnameisnotbeingused.com on your network, in the 
future that site may exist but you'll only see your own internal version.

So my internal sites have domains like
yoyomaplayscello
raycharles
nosoup4you-next
and the like.

If you're using DHCP via one of the ubiquitous broadband 
firewall/gateway thingies from Linksys or D-Link or whoever, it really 
doesn't matter.  However, most people like to give their machines a 
name, anyway, even if they don't have a domain to attach it to.

You might want to get your own domain, in which case you control the 
names in it, or one can use dyndns.org or one of the similar sites to 
obtain a reversible hostname in a domain like homeip.net, even when 
using a dynamic IP.

"Making stuff up" is ok, so long as you don't make stuff up that 
conflicts with properly configured names.  Pretending to be a host in a 
domain you don't belong to is considered impolite at best, and if you 
have a local config problem than ends up generating errors or messages 
sent to the real host (think bounced mail), you will not thrill whoever 
it is that has to clean up the mess

Other changes to rc.conf may require you to to run a startup script-- check

The proper syntax for the netmask on the second and subsequent
interface addresses from each distinct network block is to use the
all-ones netmask: you can express that either as 255.255.255.255 or as
0x or as /32, whichever suit you best. This is a FAQ on this
list but it still keeps tripping people up -- despite being clearly
documented in ifconfig(8):

 alias   Establish an additional network address for this interface.  This
 is sometimes useful when changing network numbers, and one wishes
 to accept packets addressed to the old interface.  If the address
 is on the same subnet as the first network address for this
 interface, a non-conflicting netmask must be given.  Usually
 0x is most appropriate.

However you look at it, 0xff could never be a correct netmask.

Cheers,

Matthew

Not unless you're connected to another machine and connected to the target
box through a serial console. In this case you're probably better of making
the change manually. What is it you want to reconfigure?

Well that depends on what it is, but if you want to just go through
everything you can do this:
# shutdown now

This will put you in single-user mode. Hit enter for the default shell, then
just log out (Ctrl-D) and that will fire up init and run through the rc
system again.

setting up network virtual hosts (ifconfig)

2004-03-08 Thread Jason Williams
Hello everyone,

Just was wondering about setting up virtual hosts on NIC cards on my 
FreeBSD box.
I read the handbook:

http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/configtuning-virtual-hosts.html

Seems simple enough, but I seemed to be having a bit of a problem.

For instance, I had this in my rc.conf:

ifconfig_fxp0="inet 192.168.1.91  netmask 255.255.255.0"

and tried to add this:

ifconfig_fxp0_alias0="inet 192.168.1.75  netmask 255.255.255.0"

Two questions here:

After you made a change like this, how do you restart it without having to 
reboot? There a way to do this using ifconfig?

Secondly, I rebooted my machine after testing this out, and it appeared to 
hang. When I looked at the console, it was stuck on the 'hostname' part.

I'm currently looking for additional information to see what I did wrong, 
but thought i'd ask here to see if someone can point out my error.

I appreciate the help.

Jason
