Losing Nameserver access

G

GrizzlyKing

Hello. I'm 100% new to FreeBSD. I just installed it on a recycled DeskPC with a 200GB harddrive, 1GB memory and an AMD 1600+ CPU. The install went smoothly, including installing Diablo Java and TomCat6. Some really great documentation out there for us newcomers. Thanks!

However, I seem to be losing reference to my nameserver (DNS) as is evidenced when FTP will fail with this error message:
Code: 
hostname nor servname provided, or not known
I do not, however, lose remote access over my network (using Putty) to the computer so I do not think that there is a problem with my NIC.

If I run [cmd=]dhclient fxp0[/cmd] I get the following:

Code: 
DHCPREQUEST on fxp0 to 255.255.255.255 port 67
DHCPACK from 192.168.50.1
bound to 192.168.50.72 -- renewal in 43200 seconds.

and then the FTP works correctly.

I want to use a static address and not DHCP. My firewall hardware is also a DHCP server (192.168.50.1) and it is connected to the internet via a ADLS Modem supplied by my ISP (192.168.1.1) which is thus my default nameserver (DNS).

Below are excerpts from rc.conf, resolv.conf and ifconfig. Thanks for any help.....GK

/etc/rc.conf contents:

Code: 
#ifconfig_fxp0="DHCP"
ifconfig_fxp0="inet 192.168.50.72 netmask 255.255.255.0"
defaultrouter="192.168.1.1"
inetd_enable="YES"
moused_enable="YES"
moused_type="auto"
sshd_enable="YES"

/etc/resolv.conf contents, note this file was populated by the system and not me:

Code: 
nameserver 192.168.1.1
nameserver 80.10.246.2
nameserver 80.10.246.129

ifconfig content:

Code: 
fxp0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
        options=2008<VLAN_MTU,WOL_MAGIC>

        inet 192.168.50.72 netmask 0xffffff00 broadcast 192.168.50.255

What does your /etc/resolv.conf look like immediately after a reboot, and what does it look like after running a DHCP request? I see that you have a static IP defined in your /etc/rc.conf, but that you can also get one from a DHCP server. If the latter always produces the desired result, the obvious suggestion would be to use
Code: 
ifconfig_fxp0="SYNCDHCP"
and never look back.

Then you also need to create a /etc/resolv.conf file containing your DNS servers. See resolv.conf(5).

When using DHCP this file is created automatically with the data sent by the DHCP server.
 
Your defaultrouter (192.168.1.1) isn't reachable from 192.168.50.72
If you insist on using a fixed ipaddress, you should probably point your default route at 192.168.50.1.
 
Gentlemen....Many thanks for your replies.

First, to address DutchDaemon's question, the resolv.conf after boot was as I indicated in my original post and
FTP ftp.xxx.com
failed as in my original post.

I deleted resolv.conf content and rebooted. Now the file remained empty, ie no nameserver entries.
FTP ftp.xxx.com
failed as in my original post.

Running
dhclient fxp0
fixed the problem, ie FTP worked and the resolv.conf was again populated as in the original post.

Rebooting here returned the system to its original state, ie FTP failing.

Now, SirDice, thanks for your comment. I guess since I used DHCP originally during the setup process this file was automatically created and populated. I have added a comment about this into my notes.

Finally, Jalla, I think you may have hit on the solution to the problem. When I changed the
Code: 
defaultrouter
line in rc.conf from 192.168.1.1 to 192.168.50.1 and rebooted, magic, the FTP works. I guess I had the roles of my ISP's ADLS modem/router and my hardware firewall router mixed up. A beginner's mistake.

Last, yes I know I said finally for Jalla, but DutchDaemon, you are right about setting up my DHCP server to issue a static address for this MAC address. As I am basically just 'playing' with FreeBSD I did not want to setup anything permanent at this time.

For now I assume the problem has been fixed so I will list this as solved.....GK
