My jails are not seeing the network.

[paulfrottawa]

I used this example

http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/jails-application.html

How have you determined they're not seeing the network?

Please post your jail-related rc.conf entries:

# grep 'jail' /etc/rc.conf

[SirDice]

Do realize that you can't use ping inside a jail as it needs raw sockets.

[paulfrottawa]

How have you determined they're not seeing the network?

Please post your jail-related rc.conf entries:

# grep 'jail' /etc/rc.conf

I tried a few test like pkg_add -r nano from inside the jail.

And pkg_add told you what exactly? The error message matters.

[anomie]

...
jail_ns_hostname="ns.example.org"
jail_ns_ip="192.168.0.17"
...

Can you also post ifconfig output? (i.e. Let's confirm aliases are set up.)

Since those jails are on private IP space, how are you handling NAT?

Show the whole content of your /etc/rc.conf file.!!

i guess you will need the alias on your interface


ifconfig_bge0="inet 192.168.0.200 netmask 255.255.255.0"
ifconfig_bge0_alias0="inet 192.168.0.17 netmask 255.255.255.255"
ifconfig_bge0_alias1="inet 192.168.0.18 netmask 255.255.255.255"
ifconfig_bge0_alias2="inet 192.168.0.77 netmask 255.255.255.255"


change bge0 to the interface you running with xl0 in your case, if your output is right.
(this is in the /etc/rc.conf file of the jailhost!!!)


also make sure there is a /etc/resolv.conf file in every jail.

Johan Hendriks

[anomie]

@Sylhouette: He has xl ethernet card (not bg).

@paulfrottawa: It looks like you have not set up networking at all. You will need entries similar to those posted by Sylhouette, except use, e.g.:
ifconfig_xl0=...

You'll also want to set defaultrouter and hostname in /etc/rc.conf. If you run into trouble, post the whole rc.conf file.

---

edit: I was too slow.

@paulfrottawa: are you required to be a dhcp client in your environment? That will change the advice given here...

[paulfrottawa]

I'll get onto the defaultrouter and hostname thx

I suppose I would need advice for the resolve file.

[Sylhouette]

@anomie look at the line below the ifconfig lines ;)

try the following (i see you have comment out the desired rules)

make sure the default router adres is the adres of your router/gateway

Secondly why a 25 bits mask (255.255.255.128) cant you use a 24 bits mask!(255.255.255.0)


hostname="i386.localhost.bsd"
defaultrouter="192.168.0.1"
ifconfig_xl0="inet 192.168.0.197 netmask 255.255.255.128"
ifconfig_xl0_alias0="inet 192.168.0.17 netmask 255.255.255.255"
ifconfig_xl0_alias1="inet 192.168.0.18 netmask 255.255.255.255"
ifconfig_xl0_alias2="inet 192.168.0.77 netmask 255.255.255.255"

make sure that you have no multiple lines in your /etc/rc.conf file.
the last line is used in this case
and the alias# lines must always be alias0, alias1, alias2, alias3 and so on.
You can not leave a number out, if you going to delete a line (or comment it out) you need to edit the other line so that it staill goes 0 1 2 3 and so on.




the /etc/resolv.conf file has nothing more than your name servers in it and also maybe your domain
domain localhost.bsd is not a must
change the ip adresses to the one from your ISP

domain localhost.bsd
nameserver 194.109.6.66
nameserver 194.109.9.99

[anomie]

@anomie look at the line below the ifconfig lines ;)

Whoops, you are correct. Don't mind me. :)

[paulfrottawa]

Whoops, you are correct. Don't mind me. :)

sound like i should just do a rebuild and start over.

nonething worked I re done some /etc/rc.conf here.

On host:

for dir in /usr/home/j/*/etc; do
cp /etc/resolv.conf ${dir}
done


It has nothing to do with interfaces, routing is non-existent in jails. If the host can get to the internet so can jails.

[SirDice]

The aliases aren't needed either. The jail startup script takes care of that, hence the jail_<name>_ip.

Ok I got a new install nothing else. I just did a new install last night. sync src, rebuild world and used -DNO_PROFILE (something different).

Then build my jails with this example:
http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/jails-application.html

I'm going to wait a minute before I guess the (dir) but i suppose its this /usr/home/js/ns/etc
