Software :: File /var/lib/named/var/named/reverse/named.zero Failed: File Not Found

Mar 14, 2009

Mandriva 2009, BIND 9.5.0-P2. Named will start however I'm getting the above error as well as these:

14-Mar-2009 15:45:37.084 general: error: zone 0.in-addr.arpa/IN: loading from master file /var/lib/named/var/named/reverse/named.zero failed: file not found
14-Mar-2009 15:45:37.084 general: error: zone 0.0.127.in-addr.arpa/IN: loading from master file /var/lib/named/var/named/reverse/named.local failed: file not found


Named shows to be running but with the errors above I know it's not running correctly. I also copied the above dir's over to /var/lib/named/var/lib/named which is where I 'believe' it's chroot'd at, though I could be wrong since I'm unfamiliar with chroot.

Feb 24, 2010

I have for a while been trying to setup ssh so hadoop can ssh without a password to all it's nodes. (Currenly 2 nodes)But i can not get the ssh to login without either asking for a password or just getting access denied (public key)I have been following two guidesFirst:Setting up SingleNode ClusterThen after:Setting up Multinode ClusterI have also done various ssh tutorials on setting up ssh.I got to the point where i do the command bin/start-dfs.shThen it begins asking for passwords. Which it should'nt.The problem is that ssh is not setup correcly.And whatever i try i get problems with logging in.the computers are called.

Ubuntu Servers :: Logwatch Emails Not Sent If Named Logs Are Included?

Jun 15, 2011

I've suddenly stopped getting emails from logwatch which runs on an Ubuntu server daily using cron.After a good day or so of troubleshooting, I was able to establish that it was the 'Service = named' line in my logwatch.conf file, which was stopping the emails from coming through. If I commented out this line, the logwatch emails come through with no issues, uncomment, and I don't get an email. I don't get any error from logwatch itself when I run it, even with '--debug high', leading me to think that my email configuration is setup ok, at least. Furthermore, I tried running logwatch with '--output file --format html' and logwatch produces a valid html file.

I then thought: "Could I have a entry in my Bind/named log files which could be rejected by my ISP's smtp server?". So, (to the best of my knowledge) I cleared out the log files in /var/log that contained messages from named. I then ran logwatch (including the named service in my logwatch.conf file) and I got an email through, with a pretty much empty named section, which is exactly what I anticipated. Great! - it's fixed.

So, the cron.daily ran early this morning, but still no email in my inbox when I got up. I then tried to run 'logwatch --Range today' and lo and behold, I got a logwatch report email, which included a named section, with log entries in there. So it seems that something that's been logged by named overnight to my logfiles (i.e. '--Range yesterday') has caused issues again with logwatch's ability to send reports through my ISP's smtp servers.

Fedora Servers :: Named Service Not Shutting Down

Mar 31, 2011

I am running named as a caching name server (package bind-9.7.3-1.fc14.x86_64 with config files exactly as supplied), and sometimes it does not shut down cleanly when I shut down the machine.The script /etc/ init.d/named tries to issue a "stop" command with rndc and that seems to fail most of the time; then it next uses the function killproc (defined in /etc/init.d/functions) which fails sometimes.I've hacked the named service script for now so that error messages are not hidden, but there is nothing reported.

Ubuntu Servers :: Samba - Access Folder To Delete Or Restore From The Recycle Bin Folder

Apr 24, 2010

I'm using ubuntu server 9.10 for a home build NAS. Everything is working great just have one more thing to figure out. I have Samba set up to access my files and I set up a recycle feature so anything deleted will get moved to a Recycled folder. (I learned this the hard way after hitting delete key by accident while browsing the shares in windows. Lost 100 GB of data)

Now it is for the most part working but the permissions on folders isn't getting set right. If I delete a file in a share I can go to Recycle bin folder and delete the file for good. But if I delete a folder I can not access that folder to delete or restore from the Recycle bin folder. I have to chmod the folder before I can do anything with it. Anything I can change to get folders deleted via windows to have the right permissions when it is moved to the Recycle bin folder?

Fedora Servers :: "Broken Trust Chain" From Named In Syslog?

Apr 19, 2010

I use named as a local caching nameserver (it has seemed the most stable DNS solution in the past given my ISP's flaky DNS servers) and I've noticed (since using fedora 12) a number of "broken trust chain" messages from named in /var/log/messages, for example:

named[986]: broken trust chain resolving 'www.bbc.net.uk/AAAA/IN':

I haven't made much sense of the things I've found via google, and am not even sure if this is a bad problem or not.

Ubuntu Servers :: How PID Folder Deleted Automatically

May 25, 2010

I'm new to Ubuntu (at least on server distributions). I used debian versions for a long time and thought, to try ubuntu LTS 10.0.4, because of the long time support cycle. I had problems, to install this distribution on a x86 platform (used with ASUS P4B533-v), because of kernel panic after installation. So I used a trick to get it running. I installed Ubuntu LTS 8.04 and compiled a kernel 2.6.34 and made a distupgrade. All went o.k. and is now running as a productive system.

My question now belongs to the used pid folder /var/run. I'm using some self compiled programs and had to create a separatly folder (e.g. /var/run/stunnel). My problem is, after rebooting the system, the folder is deleted automatically! Never saw this issue on other distributions. Is there any reason why? Of course, I can write a section in my init script, searching for existing folder and if not, creating it ...

Ubuntu Servers :: NAS Public Folder Not Getting Mounted?

Sep 21, 2010

We have an Iomega StorCenter ix4-200d in our office. for past two days the shared public folder is not getting mounted. but it's working fine through the web interface i.e user can upload/download.that rules out the permissions problems.

I am providing the output of mount command:

t227@t227:/var/log$ sudo mount -t cifs --verbose // /mnt/public/ -o username=shrey
[sudo] password for t227:


in fact i can't access any of the folder which I am having permissions to rw.but it's working fine through the web interface.

P.S:- On windows also I can't mount the folder.

Ubuntu Servers :: Automatic Folder Copy/tar Under 10.10?

First off I'm running a headless Ubuntu server 10.10 box.I have a single folder on a ntfs drive that I wish to copy somewhere else on the same HD. I'd like this to automatically happen about once a week or so. It would be even better if it would tarball the copy also..but this isn't a 100% necessary.

Something like "XFOLDER" would be copied to "/backup/XFOLDER1.tar" then next time "/backup/XFOLDER2.tar" and so on.

Ubuntu Servers :: Share Folder For Streaming To DVD Player?

Feb 23, 2010

Anyone know if you can use samba to share a folder to stream music and video files to a wireless enabled dvd player? I have a machine running Ubuntu server and have all my music stored and shared using nfs with my network computers. I just got a Samsung BD-P3600 blu-ray player that has wireless for blockbuster, netflix, pandora, and you tube. You can also setup a shared folder on a Windows system to allow play back on the blu-ray player. I was just wondering if anybody has tried it with ubuntu and samba.

Ubuntu Servers :: Renaming Files Recursively From Folder

Mar 26, 2011

I'm trying to rename files recursively from a folder. I want to delete the & from every filename. i've searched the net and found the following script:

for file in `ls $dir` ; do
newname=`echo $file | tr '[a-z]' '[A-Z]'`
mv $dir/$file $dir/$newname
and changed it:

for file in `find $dir -type f` ; do
#rename files containing &
newname=`echo $file` | tr '[&]' ''
mv $dir/$file $dir/$newname

But the for loop explodes the filename after each & sign, so i don't have a whole filename. if the file is named lorem & ipsum, the for loop will break it in 3 parts.
