I've got an interesting problem when it comes to wildcard entries in bind. If I put the following in:
qa.express IN A 172.16.0.10
* IN A 172.17.1.156
If I then look up "express.example.com" it doesn't return an answer - it *should* return 172.17.1.156, but it won't unless I put that hostname in specifically. qa.express.example.com resolves as expected.
what is bind vs bind-chroot vs caching-nameserver ?what is the different between eatch others ?
View 7 Replies View RelatedI have been running two Ubuntu 10.10 servers for some time now. My main server is 10.111.1.65 and backup server is 10.111.66. The main server is to host my website and ssh remote access (Key auth). The backup server pulls via ssh key auth what is in my /var/www (among other folders) to the backup home dir (encrypted). For some reason today I checked the uptime and it was 7 hours on both servers. All my other computers on the same power supply have a uptime of over a month. For some reason I now cant access backup via ssh from main's key (I could before) and I can not get to the home dir, see below:

Have a bit of a dilemma I'm trying to track down. Have a user using both date and ps commands with & at the end of the line in a shell script. When he runs the script, it waits until he hits ENTER to get back to a prompt. Other times he doesn't. Also, I've noticed that this will sometimes happen, then immediately rerun the script and the behavior stops.
View 1 Replies View RelatedI've been using dhcpd for address assignments to PCs for a very long time with no issues. I recently upgraded from lenny to squeeze and now dhcpd seems to have new behavior which I can't seem to change. Here's what I want to do. First, I have a simple situation and don't want to get involved with dynamic DNS updates. I have host statements for each of my PCs and a range statement for cases where I install a new device and don't yet have a host statement for it. Previously, I could discover the ethernet address for the new device from the dhcpd log and add a host statement with an address of my choosing for the new device.
I'd then restart dhcpd and do something like reboot the device or issue an ipconfig /renew statement on the new PC. What would happen is that the old dynamically assigned IP address would be NAKed and the device would do a DHCPDISCOVER, etc. and get the new IP address I specified in the dhcpd.conf host statement. In squeeze, this no longer works. The client asks for the old address it got dynamically and the server just says yes. I can't seem to find a way to get it to NAK the dynamic address and use the new address I've specified in the host statement. I'd appreciate any enlightenment on how this is now supposed to be done. Here's my simplified dhcpd.conf file:
authoritative;
log-facility daemon;
ddns-update-style none;
[code]....
Note that the address here was assigned based on a previous range statement and isn't consistent with the above config file.
I've noticed something strange in the behavior of how Ubuntu server obtains it's IP address versus Ubuntu desktop and other versions of linux and Windows. When Ubuntu desktop obtains an IP address from my router that address is retained from one bootup to the next, same behavior as Windows, SuSE, and pretty much any other OS. Ubuntu server on the other hand grabs a different IP address everytime it boots. At first I guessed it was a difference in /etc/dhcp3/dhclient.conf so I replaced it with the dhclient.conf from Ubuntu desktop but no dice, it still grabs a new address every time.
In /etc/network/interfaces Ubuntu server defines the loopback interface and primary network interface, just as it should but Ubuntu desktop does not define the network interface, only the loopback interface. I'm guessing something else controls does this. Desktop appears to be storing previous IP lease information in /var/lib/dhcp3/dhclient.eth0.leases but server doesn't, /var/lib/dhcp3/dhclient.leases is always empty and there's no other files in /var/lib/dhcp3/.
Apparently something isn't writing old lease info there. Without setting a static IP address, how can Ubuntu server be configured to retain the same IP address between boots like Ubuntu desktop?I'm using Ubuntu server 8.04LTS, Ubuntu desktop 9.10 & 9.04, SuSE 11.0, Linux Mint, Windows XP, pfSense 1.2.2 as router.
I'm try the use wildcards for file searches in Nautilus (ctrl+s) but using sets and character classes doesn't return any results. For example
[[:upper:]]*
[![:digit]]*
*[[:alpha:]]

Is this kind of notation supported in Ubuntu or do I have something wrong in my syntax.
I searched and I found a few threads on this but none answered my question really.I'm using:

from the page source, but it's not giving me that, it gives me <h2>.. followed by a loads of other stuff that I don't want. I haven't used wildcards with grep before so I don't really know whether I'm doing it right or not.
I and setting up a home web server using Ubuntu 10.04 server (local only). I am currently using Webmin 1.53 to access it remotely all is going great very easy to use. Webmin - Check, ftps-fileZilla - Check, Apache -It Works BUT I cant seam to set up Apache as a named server using Bind DSN. Tried most of the help in the fourms and .....

View 3 Replies View RelatedI have a BIND server that I'm setting up with different views. There is another server out on the public Internet that currently handles all inquiries for this domain.

Is there a way to do a batch renames of files that will keep each individual filename, but change it in the way I want?
The specific issue is this. I have a harddrive with something like 1300 movies on it. They're all organized alphabetically, but there are like 200 movies that begin with 'The'. I want to rename all of these movies that begin with The so that the The at the beginning is dropped and added at the end (for example, turn "The Shawshank Redemption" into "Shawshank Redemption, The"). I'd like to do this with a simple command if its possible.
I am trying to clean up a collection of music files, often in windows i receive errors on the collection because some of the files have a "?" question mark in the file name, in windows this is not a valid character for file names. How can i search/find files with a question mark in the name? Each time i try to search for "?" i receive a list of items that match a wildcard search where ? is a wildcard. I want to find file names that actually contain the character "?".
View 2 Replies View RelatedI am cleaning up some text files to put on a website and am using the find/replace feature of Gedit extensively. The only problem I am having is that I can't find a way to use wildcards. For instance, I want to use the "?" and "*" in the same or similar way you do in bash. I already know that:
Represents a carriage return, and that is great, but I want to do something like: "?." to replace "A.", "B.", "1.", "2." with just plain spaces. The document in question is written in narrative, but has a bunch of outline markers in it, and I want to remove the outline markers.
I tried "escaping" the characters in a similar way as by using "?.", but that didn't work. Google was not very fruitful, and the Gedit help seems to be Gnome help and includes all kinds of useless info (for my problem) about wildcards in other programs.

I am still quite new to all this but I guess we were all beginners once, this forum seems very helpful.Here is my situation, I will give as much detail as I can.I have a dedicated server which is running CentOS release 5.5.Initially I had Plesk installed, but when I upgraded PHP I damaged the Plesk configuration, and so I installed Webmin instead.
All seems to be fine with this, apart from the DNS configuration / BIND server.I know this because I have one site which uses an external DNS server and this works fine (i.e I can access it from a browser). All the others don't resolve - i.e the ones I set up in Plesk.I've done a bit of investigating to see what is going on, but I'm stabbing in the dark a little.
I've been looking for a good tutorial for setting up a BIND DNS server for my local network. What I want to do is..Have BIND running on my home server receiving all DNS requests.Have certain zones (my.zone.lan) pointing to custom IP addresses (I.E. server.lan points to 192.168.{server IP})Zones that don't exist should be passed on to OpenDNS for processing.

this code seems to work but I'm not quite satisfied with it. I'd like to get rid those IFS changes, but haven't found out a solution as of yet. Problem with default IFS seems to be that with it neither $pattern or "$pattern" work; it either interprets pattern as multiple words (because of spaces) and so expands to wrong paths or it ignores * because it's within quotes.

View 2 Replies View RelatedI have read a lot of documentation but it is still hard to find a proper answer to my doubts.About the hostnames in a domain, how is it associate to a determinated port?
For example, when I type on the browser webmail.sparc86.net and then I get redirected to the port of 20000 of this same domain. Fine, but how does it work that it knows it should be redirected to the port 20000? From where is this information (the association webmail-port 20000) taken? The apache will manage this, right? But what about other services like ftp?Another example, If I wrote my own software listening, let's say on the port 40000 and I want to have a domain like "mystuff.sparc86.net" how would I let it be redirected to the port 40000 ?
Currently i using webmin,but it missing some important things like $variable -where $variable would be automatically replaced with added domain,and it's kind a strange since plugin for managing other dns server on webmin does that. Also i was not able to generate 100% correct all records,only partial,which make it useless since i was need to fully replace it anyway.So can someone recommend any script/tools for it?I would be even happy with combination of batch tools(which might be even best solution since then i would not need to bother with installing script). How my dns records look:
