How to force a static /etc/resolv.conf?
I'm running 9.1. I run a local recursive resolver, so my /etc/resolv.conf needs to remain static. I have DHCPv4, DHCPv6 and VPN clients running which all want to modify /etc/resolv.conf.

resolvconf overwriting /etc/resolv.conf
Hi, I run bind on a LAN, with some LAN-only (sub)domains. On the LAN is also a DSL modem/router that advertises ipv6 addresses. So far so good. However, since I upgraded the server from 8-STABLE to 9.1-PRERELEASE, the /etc/resolv.conf gets overwritten by the resolvconf script, with an ipv6 nameserver (presumably the router, haven't checked). This is not what I want. Now I see that you can prepend nameservers through /etc/resolvconf.conf, but what I really want is for resolvconf to leave my /etc/resolv.conf alone. Is there any way to disable the script (apart from deleting it)? thanks, Ruben ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"

Actually I'm using hooks in devd(8) like:
$ cat /usr/local/etc/devd/tun6.conf
notify 0 {
match "system" "IFNET";
match "subsystem" "tun6";
match "type""LINK_UP";
action "/usr/local/etc/devd/tun6.sh $subsystem $type";
};
$ cat /usr/local/etc/devd/tun6.sh
#!/bin/sh
#
echo `date`: $0 $* >> /tmp/devd.out
(
sleep 30 ;
echo Doing: /etc/rc.d/sendmail onerestart >> /tmp/devd.out ;
/etc/rc.d/sendmail onerestart ;
)
exit 0
for each interface which might come up; but I was thinking that
there must be a more general solution in sendmail or DNS itself;
in any case, thanks for your idea;

sendmail && /etc/resolv.conf modified by DHCP
Hello, At home I have my WLAN as 192.168.2.0/24. After moving to my office and rebooting there, I encounter that sendmail receives messages (via fetchmail) terrible slow. I digged into this and see that the sendmail issues wrong DNS requests as (for example): 08:51:18.753491 IP xx.xx.xx.xx.49812 > 192.168.2.1.53: 12793+ MX? ubuntu.com.Sisis.de. (37) 08:51:18.867365 IP xx.xx.xx.xx.42619 > 192.168.2.1.53: 12793+ MX? physik.uni-wuerzburg.de.Sisis.de. (50) 08:51:18.982491 IP xx.xx.xx.xx.52554 > 192.168.2.1.53: 12794+ ? lexasoft.ru. (29) 08:51:19.095490 IP xx.xx.xx.xx.10093 > 192.168.2.1.53: 12794+ ? des.no. (24) The reason is obvious: - the /etc/resolv.conf on shutdown at home has this DNS resolver; - in my office the system comes up and when at some point the WLAN interface associates, it gets an IP and a new /etc/resolv.conf file; Why sendmail does not honour the new /etc/resolv.conf and stays with the old DNS server IP? How this is supposed to fix? An idea would be to restart sendmail via a devd hook, but maybe there is some config values for sendmail that it always check /etc/resolv.conf for fresh?

Looks like you're using ipfw, in which case this works for me:
# /etc/rc.d/ipfw restart

In dhclient.conf, add your own DNS servers, plus your ISP's as backup:
Interface "xl0" {
prepend domain-name-servers xxx.xxx.xxx.xxx, yyy.yyy.yyy.yyy;
request subnet-mask, broadcast-address, routers, domain-name-servers;
}
Get new ip:
# dhclient xl0
Hope this helps

This is a problem that people see when they need to update a local
dhcp server on a machine that gets its own settings by dhcp. Try google.

I doesn't appear to matter, I think dhclient bypasses the firewall. at
least that's my experience with PF.

Re: ip refresh, resolv.conf and local scripts on startup?
hrm, thanks, but this doesn't seem to work:
`ifconfig xl0 down` doesn't do anything... executes without error, but the
interface stays up.
`/sbin/dhclient` gets a new IP, but doesn't "re-do" the firewall with new
IP, so everything is broken.
echo nameserver 123.34.45.67 > /etc/resolv.conf
echo nameserver 321.23.67.328 >> /etc/resolv.conf
This is over written on startup/reboot by the dhcpclient. If I modify the
file, then it tries to "correct" it self and over writes the file with the
DNS servers provided via the DHCP server.
Any other ideas?
Thanks,
Jack

ip refresh, resolv.conf and local scripts on startup?
I have a script that updates some dynamic DNS records (can be run as
non-root if needed).
It needs to be run on startup - after network is configured and after
rc.firewall (it'll get blocked if it's run before the firewall is setup).
What is a good place to put this? I could put it at the end of rc.firewall,
but is there a better place to put it?
Also how do I refresh a dynamic IP without rebooting?
Sometimes my cable modem gets messed up and under windows I just do:
ipconfig /release
ipconfig /renew
and it gets new IP and sets everything up. In FreeBSD is there a way to
reconfigure everything without rebooting?
(rc.firewall uses this to get network info:
onet=`ifconfig xl0 | grep "inet " | awk '{print $6}'`
oip=`ifconfig xl0 | grep "inet " | awk '{print $2}'`
Meaning, rc.firewall would also have to be re-ran if the IP is new).
[also to make things more complicated, I think I need a rule in
rc.firewallto allow for DHCP clients to go out? It gets blocked on
external interface
when firewall comes up??]
Also how do I override /etc/resolv.conf? DHCP client configures it I think
and sets it up to point to my ISP DNS servers (which suck) and would like to
give it mine instead of there, but it keeps getting over written on startup
when it gets a DHCP lease?

Your best recourse then is to find out the IP numbers of your ISPs DNS machines -- either by consulting the ISP's documentation or web site, by asking their support team or by looking at the results obtained by running PPP with 'enable dns'. Then make sure your ppp.conf does not overwrite your /etc/resolv.conf on connection, and just edit resolv.conf to insert the IP numbers you've discovered. A static resolv.conf will serve you well enough. After all, it's not like your ISP will be changing their DNS servers every few hours.

It's dhclient, not ppp that's modding the file. Adding this to your
dhclient.conf file will fix the problem
interface dc0 {
prepend domain-name-servers 192.168.0.10;
request subnet-mask, broadcast-address, routers, domain-name-servers;
}
you will need to change the interface name and provide the actual dns server
address to match your configuration

IMO, i think your setup is fine. my opinion, is that 'search' is more useful
than 'domain'. they have the same basic functionality, until you need to
search more than one domain by default. but with just a single name, they
seem to be functionally the same.

dhclient.conf + resolv.conf
I am trying to have dhclient setup my resolv.conf perfect.
I am very close.
I have this in dhclient.conf:
-
interface "bge1" {
supersede domain-name "wixb.com";
prepend domain-name-servers 192.l68.1.1;
request subnet-mask, broadcast-address, routers, domain-name-servers;
}
-
What this is giving me is this:
search wixb.com
nameserver 192.168.1.1
nameserver 24.94.163.100
nameserver 24.94.163.101
What I would like to do is change the 'search' to 'domain' and cant
figure out what I am missing?

I do not use any special DHCP client, but I use mpd(8) to connect via ADSL. I thought, mpd has created these entries. But when I temporary moved resolv.conf and restarted the computer, no resolv.conf appeared.

They could have been, if you selected DHCP configuration.

resolv.conf and IPv6 and DHCP for IPv6
Is there anything different with entries in resolv.conf for IPv6 addresses? I'm looking at the manual page for resolv.conf and didn't find anything specific to IPv6. Therefore, I'm assuming that the entry would simply be: nameserver fec0::3 vs. nameserver 192.168.0.1 Or whatever. Is this correct? Secondly, does there exist any documentation for configuring the dhcpd program from ports?

I foudn something like that on google. Also a file named dhclient-enter-hooks seems to do the trick, but I miss the option to just say "don't use my existing resolv.conf" badly. On linux it's easier as I remember (but that's years ago, so things might have changed there too. The initialising in a specific order is more important to me at the moment.

The script I sent are operational on FBSD 4.11 with the enter/exit-hooks scripts that are part of the base install. NB Dont forget I run the ipf firewall rewrite rules script manually as root when my IP number changes, but the DHCP -> resolv.conf is automatic via exit-hooks The scripts are always called by dhclient, what I put in them is what I attached. And I am also using Postfix ... As far as I remenber pcre is only needed by Postfix if you use pcre: regular expression type files in main.cf. If you use regexp: then pcre is not used.

RE: Getting DHCP to use resolv.conf?
I got this from the ISC-dhcp questions list. Note: This might not work, Not tested, No guarantees. Use this as starter code and after testing post what you get working for the list archives. In dhcpd.conf comment out the line "option domain-name-servers" and add following line include "/etc/dhcpd.name-servers"; This will include the contents of the named file into dhcpd.conf. It is easier to manipulate a small separate file containing only a single line, rather than trying to manage the whole dhcpd.conf file Every time dhcp-client runs it will try to run /etc/dhclient-exit-hooks file if it exists. Create a empty /etc/dhclient-exit-hooks file and populate with this ### Start of refresh dhcpd dns ip # This script will propagate to dhcpd the changed dns servers ip address # which dhcp-client puts in resolv.conf. # # In dhcpd.conf replace the "option domain-name-servers" line with this # # include "/etc/dhcpd.name-servers"; # # Spript uses the dhcpc variables to build temp line in dhcpd format. # Then compare temp content to production content. # If different replace production content with new content from temp, # and restart dhcp to reread dhcpd.conf containing new ISP dns ip addresses. # # logging event and sending email to user root is optional. # # Note: All LAN machines using dhcpd will not get new ISP dns ip addresses # until they reboot or their lease comes up for renewal. # # Each of the following lines must be one long line. IE: no wrap arounds # load my_domain_name_servers variable with ISP dns ip addresses from dhcpc my_domain_name_servers=`echo $new_domain_name_servers | sed -e 's/ /, /g'` # Create single line in file to be included in dhcpd.conf echo "option domain-name-servers $my_domain_name_servers ;" > /etc/dhcpd.name-servers.tmp # See if different from what production file contains cmp -s /etc/dhcpd.name-servers.tmp /etc/dhcpd.name-servers if [ $? -gt 0 ]; then # move the new file into place mv /etc/dhcpd.name-servers.tmp /etc/dhcpd.name-servers # restart dhcp using whatever is appropriate for your platform #service dhcpd restart /usr/local/etc/rc.d/isc-dhcpd.sh restart -q # Write message to log to document event. logger -t dhclient ISP DNS IP address changed to $new_ip_address # Send notification email to root user. This can wrap to next line. mail -s "dhcp client changed ISP DNS IP addresses" root The dhclient-exit-hooks script was invoked and has determined that your ISP changed the IP address of their DNS servers. The new values have been auto updated to dhcpd.conf and dhcpd restarted so they are now in effect.

RE: Getting DHCP to use resolv.conf?
I read the man dhclient.conf(5) and paid special attention to the part about prepend domain-name-servers. It does not say anything about passing the dns info dhcp client puts into resolv.conf onto the dhcpd.conf "option domain-name-servers" statement. I don't think you understood the original question. I may be wrong so please explain how dhcp client prepend domain-name-servers option effects the dhcpd config file? -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Behalf Of michael johnson Sent: Thursday, April 27, 2006 7:36 AM To: Bill Moran Cc: Telting; freebsd-questions@freebsd.org Subject: Re: Getting DHCP to use resolv.conf?

Presumably all three ranges have distinct domain names E.g. company1.de company2.de company3.de I am no expert of DNS, but isn't all you need for each "company" to run nameservers which are slaves (secondaries) for the other 2 as well as master of their own? So the nameserver at company1 is master for company1.de and is a slave for company2.de and company3.de etc. Of course, you might want some redundancy in that scenario, with each company running DNS on another server as well, and that one being a slave for all 3 domains. If you don't know enough to do that, I strongly recommend getting the latest edition of O'Reilly "DNS and BIND"; and you should find BIND doc on your FreeBSD system starting in /usr/share/doc/bind9/arm/Bv9ARM.html.

You need to use supersede like this:

supersede domain-name "yourdomain.com";
supersede domain-name-servers 127.0.0.1;

See man dhclient.conf for more options.

Ok, let's get to the point: my problem is with DNS resolution, form some

As you may have seen already, this is a common issue with systems running
dhclient. It will overwrite the resolv.conf with the ISP provided dns
information as soon as it obtains it from the dhcp server. To counter this,
do this with your dhclient.conf file (/etc/dhclient.conf) and create a
prepend entry for each server you want to answer your dns requests. Take
note, the file is read from top to bottom and in the example below,
127.0.0.1 would be the primary dns server for your system.
interface "rl0" {
prepend domain-name-servers enteryourdnsiphere
prepend domain-name-servers enteryourdnsiphere
prepend domain-name-servers 127.0.0.1;
}

Re: resolv.conf
Ronny,
It sounds as though this is something to do with the DHCP client software,
which can be configured through /etc/dhclient.conf.
Something like the following might be a workaround, but I'm
not an experienced user of PPPoE and may be barking up the wrong
tree.
interface "rl0" {
prepend domain-name-servers ;
request subnet-mask, broadcast-address, time-offset, routers,
domain-name, domain-name-servers, hostname;
require subnet-mask, domain-name-servers;
}
HTH,

My question is: how to reliably keep your own nameserver in
/etc/resolv.conf, and get around the frequent protocol updates that
change/nullify your mods to /etc/resolv.conf.
Perhaps just a regular script that does a diff and patch of it, or
simply copies over the file you want regularly. Not elegant but it
would work.
According to dhclient.conf(5):
supersede [ option declaration ] ;
If for some option the client should always use a locally-configured
value or values rather than whatever is supplied by the server, these
values can be defined in the supersede statement.
I've never had to use this myself, but I would expect that something like:
interface "foo" {
...
supersede domain-name-servers 127.0.0.1;
...
}
would do the trick in your case.

I also wonder about creating a dhclient-exit script that would update

In resolv.conf should be: nameserver a.b.c.d where a.b.c.d is the ip address for the DNS server provided by your ISP. If the IP address being provided by is a 192 address, you're bound to have problems. In other words, if your ISP has given you DNS servers to use, use them. If not, find one. ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"

There seems to be a known issue the way Mozilla resolves under FreeBSD. There were some good threads in the news groups and mailing lists on this; You should be able to find them via groups.google.com by searching for something along the lines of "mozilla DNS slow". There are few couple of reported ways to get around the resolvers issue. I've read that disabling IPv6 in your kernel will help. Installing the Linux native ports (e.g. www/linux-mozillafirebird or www/linux-mozilla) is also reported to work. I haven't tried either of the fore mentioned workarounds, so I don't know if they work or are still applicable. I route my web traffic through the Squid proxy (available as a FreeBSD port www/squid). As a result, I'm not affected by the resolvers issue since Squid is handling DNS resolution for browsers on my network. I'm not saying my work around is the best fix; I just happened to need a proxy on my network so it was a convenient fix way for me to deal with this issue. -Ash ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
