OpenSUSE Network :: Warning: Name-Server Ns.xxxxx.ch (nn.nn.nn.nn) Answers Recursive Queries
Jul 19, 2010
I have registered 2 nameservers running bind for a certain domain. The log file of my domain name provider (SWITCH) shows the following warning:
Warning Der Name-Server ns.xxxxx.ch (nn.nn.nn.nn) beantwortet rekursive Anfragen.
In English that would be:
Warning: Name-Server ns.xxxxx.ch (nn.nn.nn.nn) answers recursive queries.
The NS triggering the warning is running openSUSE 10.2 and the other one 11.1. Both configuration files /etc/named.conf are equivalent (well, forwarders are different). There is no such warning for the NS with 11.1. When I add "recursion no;" to the options in /etc/named.conf the warning goes away, but FF or SeaMonkey running on the server no longer get their DNS requests resolved.

I have a transparent proxy Squid-3.0 on Slackware 12.2. I used cron to restart squid every day at 7:30 AM (just /path.to.squid/squid -k kill && /path.to.squid/squid) Some days ago I saw in /var/log/messages that Squid was killed but haven't started. I started it manually and everything was OK. But today everything repeated. And the log file is interesting. I tried to find about it on http://squid-cache.org/ but al in vain. This is from /var/log/messages :
Code:
May 24 07:30:02 konura squid[17188]: Squid Parent: child process 17199 exited due to signal 9
May 24 07:30:02 konura squid[19038]: Squid Parent: child process 19040 started
May 24 07:30:03 konura squid[19038]: Squid Parent: child process 19040 exited with status 1
May 24 07:30:06 konura squid[19038]: Squid Parent: child process 19045 started
[code]....
I need to say that I haven't edited the config file for a long time, but this problem started to happen. ADDED, Solved: I'm not sure, but maybe I found the decision. I deleted about 400 mb of Sarg logs from /var partition. And now squid runs well. Besides, before deleting old logs, 'crontab -e' and 'pkgtool' didn't work And the system wrote me that it's no space left on device. At the same time, 'df -h' showed me that all partitions had enough free space. Seems strange, but that's it. After deleting old proxy statistics, generated by Sarg (this is about 400 mb) 1)squid runs OK and 2)there are no more that annoying messages about abscence of free space.

I am trying to use a ZTE AC2726 USB EVDO Modem on openSuSE Linux 11.3 Gnome to connect to the internet. I have edited the /etc/wvdial.conf file as follows:
[Dialer Defaults]
Modem = /dev/ttyUSB0
Baud = 57600
Init1 = ATZ
Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
Init3 = .....
When I execute the wvdial command on the terminal the following error appears
joey-suse:~ # wvdial
--> WvDial: Internet dialer version 1.60
--> Cannot get information for serial port.
--> Initializing modem.
--> Sending: ATZ
ATZ
OK .....
The /etc/resolv.conf file has the DNS addresses as below
nameserver 212.49.70.22
nameserver 212.49.70.23
How do I resolve this and connect to the internet?

I am currently running the latest version of Bind, and for some completely unknown reason I can NOT get queries to work for PTR records. All queries to the servers for reverse name lookup get query denied:
Using domain server:
Name: 66.150.173.1
Address: 66.150.173.1#53
Aliases:
Host 27.173.150.66.in-addr.arpa not found: 5(REFUSED)
And it shows in my logs:
I am at my wits ends with the piece of crap. Can anyone shine some light on why this damn Bind install won't respond to these queries?
For reference here is my named.conf:

I have internal-only email server that has internal BIND9 running. Thought it only has its IP address defined in /etc/resolv.conf, it is still resolving outside addresses.

How often are dns queries sent? Assume I want to connect to a ssh server, will I send one dns-query in order to do that or do I send multiple during my connection? What if I request web-pages, do I send a query only when I enter a site or will I send queries every time I visit a new page on that site?
I'm asking since I'm considering getting an account at dyn.com (the standard account for $30/yr) and it comes with 600 000 queries per month (which is way more than I expect to get but knowing exactly what it means is always good).

Is there a way to run queries against a Microsoft sql server from linux? Here is what I would like to do. When I create apps that us db back end I would like to quickly check results of my queries. so if I could do something like "select * form Orders" from the terminal or another app that would be great.

I have my bind9 DNS server running on Ubuntu with logging on. What's bothering me is that I have log full of localhost queries instead of from IP of the computer which actually asked.DNS queries log:/var/log/named.queries.log

I have this ISP grade Nameserver running on BIND 9.5 on Fedora Core 9 64 Bit.
Its been pretty working well for sometime until a last week when we noticed it stopped resolving for our clients using on our service.
It gives correct authouritative answers for our own ISP domain with the A, PTR and MX intact but does not return resolving queries back to clients.
Below are my files
This is the message from /var/log/messages
The 41.223.x.x and 41.215.x.x ip address are from our ISP subnet and so are our own clients being denied.
The box is also hosting our traffic graph server which is on a LAMP but listens on another IP/ethernet card.
So far the load on the server is minimal as is a Dell R200 rack server.

I chose -Server-, if this is more appropriate in -Networking-, just let me know. Basically, I need to be able to merge responses stored in a zone file with responses from an "upstream" authoritative server. I'm in the sad position of needing to "intercept" requests to *part* of a domain (but not restricted to a sub-domain!) and return results for *some* hosts that use an internally routed address, and results for the rest using the public internet addresses. Unfortunately, it's not my domain, so I can't just use views (although I suspect they could end up having some part to play in this, at least potentially)... but instead I have to actually send requests recursing to the other site's external DNS for any hosts my server doesn't have records for in the zone file.
Some background on the situation:
I work at a local government, which has a private link / VPN connection to a state government entity, and needs to use internal addresses for some of the state servers, which then get routed over an "internal" network link. But the state uses the same domain name internally and externally, just presenting views to internal clients vs. external clients. -- However, we are only being allowed access to certain of their servers through the internal link, which means that for any other servers that we don't have internal/private access for, we have to visit the public addresses just like anyone else on the internet... So, I can't just send all requests to their internal DNS and get responses, because we'd get IPs for some servers (e.g. their main web site) that we wouldn't then be able to reach using the internal network link.
For Example: Say I have a client machine, "client1", on my network ("my.net"), which uses "mydns1.my.net" for name resolution ... and which needs to access 2 servers on the state network, "private.st.us" and "public.st.us" -- so named based on how "my.net" needs to access them.
The external state DNS server/view ("ext-dns.st.us") responds to requests with something like:
private.st.us -- 1.2.3.456
public.st.us -- 1.2.3.457
(Those are just crap addresses, obviously.
The internal state DNS server/view ("int-dns.st.us") responds to requests with something like:
private.st.us -- 10.0.0.8
public.st.us -- 10.0.0.10
This works on their network because their own clients have access to all such IPs.
But for us, they only allow traffic flowing between "my.net" and their internal network to reach the 10.0.0.8 address, blocking all other address destinations. So, when "client1.my.net" asks "mydns1.my.net" for the address of "public.st.us", I need "mydns1" to recurse out to "ext-dns.st.us" to get an answer (1.2.3.457) and then return that IP to "client1" -- because "my.net" is blocked from accessing the server's 10.0.0.10 address. But, when client1 asks mydns1 for "private.st.us" I need to pull the IP (10.0.0.8) from a local zone file instead of asking either of the state DNS servers -- or optionally forward the request to "int-dns.st.us" I suppose -- because the state blocks access to certain services (which we need and are the whole cause of this problem!) via the public (1.2.3.456) address.

works fine on a FAT32 dsk:
Code:
fgrep -iRn -C 2 'print' *.txt
---also recurses one level and displays all kinds of data
---------------------------------------------------------------
in root / ext4 directory:
Code:
fgrep -iRn -C 2 'print' *.* or fgrep -iRn -C 2 'print' *.txt
---displays msgs:
fgrep: *.*: No such file or directory
and
fgrep: *.txt: No such file or directory
I am probably missing something very basic.recursive does not seem to work from root directory.Is this (as they used to say) a feature? This is on an 11.2 system, upgraded to 11.3 (ran zypper verify to verify. According to it.. all is well).

trying to configure a Centos 5.5 server (simple file server with DHCP and DNS relay). I configured and tested the config (by 'service dnsmasq configtest') of dnsmasq and I got the message 'dnsdomain:host unknown (translation of the real message : hte inconnu) and I didn't find where I could define this host ! The hostname of the server is well defined and I can see it from all Windows PC's on the LAN. dnsmasq starts (with hte same message as in configtest) but when querying DNS from PC's te.g. trying to surf the Internet), I don't get replies (3 DNS servers are also well defined and operational).

I am using BIND9 and I wand to deny some queries per domain basis.Example: I don't want client1 to query the server for Ip address (A) for domain.comThe server should respond with an error, no such domain, nothing, etc.It's not authoritative for domain.com. I don't want the server to resolve recursive or iterative that domain.

I have 2 questions of which i can't find any answers to.
1) every time when i download something using lottanzb, lottanzb doesn't unpack the files automatically. It happens to every download. [URL]..0dselectie001p shows the full folder where files are downloaded in.[URL]..shows what happens to the par2 files.I don't know what is going on and why lottanzb is doing all this.
2)I have a external disk divided in 3 partitions. 1 partition is a partition for my email program (Icedove) whit all the necessary files. Since a few days i noticed that i first have to access the external disk and/or partitions before it is "active". I.e.: when my pc is started up and i start Icedove, i don't see my mail and all the (sub)folders i created (all the mail is on a partition on the external drive). But when i first access the partition containing all the mails and then start Icedove, then i see all my mails and (sub)folders.

I'm new to networks and servers, been using Linux on the desktop for a while now but always relied on the company's IT guy for setting up everyting LAN-based.
Now I want to build up my home LAN, and want to do it with Linux. I've managed to set up LAMP and file share servers.
What I am looking for is information on what I need, and how to set up a server for the following tasks:Centralized Username and Password, that when the user logs into any one of the desktops in the LAN, it uses this for authentication
Something that allows this authentication to be utilized in other servers (file access, web access, router logging, etc.). Something to make it easier for continuing permissions from one service to another. e.g. I have IPCop filtering content, and it has provisions for tracking who is making which request if there is authentication going on. (optionally) to run a script for mounting Samba shares or mapped network drives so from one system to the next. For example, in whatever box somebody logs in, it mounts a server share ("smb://Myserver/users/<username>") to a local folder ("my_user_share").
So;user "fred" ="smb://Myserver/users/fred" and user "wilma" = "smb://Myserver/users/wilma" but both would find their respective one mounted under "~/my_user_share". This would be irrespective of which box they are loggin in with. If the server share location changes (new server/servername), I change it on the server so the next time they log in it points to the right place.
I guess it is similar to Window's Active Directory, though I'm not sure what it's called, how to configure it and what it is and is not capable of doing.

I have an opensuse 11.3 install which I want to set up as a network boot server to install Solaris 10 on a Sun Ultra 10 client. According to what I've read, this requires rarpd and tftpd which I've set up on opensuse, but also bootparamd which I can't find for 11.3. It seems it was last included with opensuse 9.2. Does anyone know if it's available, if I could use the suse 9.2 version, or any alternative?

When I installed OpenSUSE 11.1 on my server, at some point, I gave the server a description. Whenever I connect to any of the shares on the server, this description appears. For example, on one Windows workstation, there is a share which appears in Windows Explorer as "Midwest on 'Cincinnati Corporate ISS Server (ISS0042)' (T:)".
For the life of me, I cannot find where this description, "Cincinnati Corporate ISS Server", is stored. I've search through /etc, and poked around ad nauseum in YAST, but I am missing it. Where is this description stored? What is the YAST function to change it?
