Programming :: Named Hints Update Script?
Mar 27, 2011
I need help getting this bourne shell script working properly. This script I found online while reading some tutorials on getting a caching name server running, which is supposed to update the rootserver hints file.
The below case statement always returns that the hints file has failed. Even though when I check the file it looks normal and I can see the NOERROR status in the returned header.
Code: dig (at)e.root-servers.net . ns >root.hints.new 2> errors
case `cat root.hints.new` in
*NOERROR*)
# It worked
[Code]..

I have a toplevel window that I want to place depending on another toplevel window. I use gtk_window_move(widget, x, y); At startup this function is called several times and y is changed ones from 412 to 413 and x is always 0(checked with gdb in netbeans). The window gets placed at x=10 and y=400 or so. If I do not use variables but pure ints for x and y it gets placed correctly even if its the same values. I suspect that my window manager notice this change of y and place the widget for me. Is this correct and how do I tell the WM not to do so?
This change of y is due to window size is just a local size and not the correct one as in X. Can i force uppdates from X to the local cache?

I need to compare two lists, and if a line exists in file 1, delete it from file 2. Here is what I am using, and it works on samples of a few hundred lines, but I have to get it to work faster on 50k lines. Has taken 7 hours so far and still no results.
result2 is master list, result1 is new list where i want every line to be completely unique--not in result2.
grep -vf result2.txt result1.txt | sed 's/ .*//' > diffs.txt

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
[code].....
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.

I am trying to read from a file named matrixA.dat that contains a matrix formatted like this:
2 x 3
1 0 2 -1 3 1
I am reading the lines in, and this is the source that I have so far: Code: #include <stdio.h>
#include <string.h>
#define DATALIMIT 17
#define DIMLIMIT 5
#define NAMELIMIT 40
[Code]...
was stored in dataA, so when I print it all I get is a newline. Why didn't it grab the 1 0 2 -1 3 1 line?

In Python 2.6.5, I could import from mx.DateTime.ISO import ParseDateTimeUTC With 2.7 I cannot.Here is the error. My module util_lib contains the import noted above.
File "util_lib.py", line 46, in <module>
from mx.DateTime.ISO import ParseDateTimeUTC
ImportError: No module named mx.DateTime.ISO
What changes do I need to make, to import on pre-2.7 and 2.7?

How to build a list of files under a directory that may have any permissible characters in the name, that is anything except NUL? The only possible (?) bash data structure to contain a list of such names is an array because NUL cannot be used as a list item separator so no X-separated list can safely be used; there is no "X" that might not be part of a file name. OK -- but how to populate such an array? Here's what I've tried.
Code:
#!/bin/bash
# Set up test files
dir=$(mktemp -d "/tmp/${0##*/}.XXXXXX")
touch $dir/foo $dir/bar
[code].....

My question deals with me creating a name pipe (file) in the my /group directory called chat.I then have to write a script to read from the named pipe and save data into a file called chat.log until the words End of File are passed to the program.
-When I created the named pipe file (chat) I used the mknod chat p command..Is this the correct command to create a named pipe file? -Then I'm having trouble with my script and how to make it run until the words End of File are entered in. This is what I have so far.

I dual booted Karmic on my old laptop. I just received my new machine, Envy 17 with a 160 GB SSD and a 640 GB hard drive with Windows 7 pre-installed. I want to multiboot Windows, Maverick and the CAElinux distro, on the SSD I am thinking. I am in the process of searching the forums in regards to partitioning strategies and hints to smooth the installs.

Programming in C++ on Fedora 13, I have a console app with code spread throughout a half dozen files.Debugging with gdb, I want to list the code from a class-member function so, at the gdb prompt I type: list 'classn and when I press <tab>, gdb completes the classname for me: list 'classname Next, I add the scope resolution operator and then type the first few characters of the function name and again press <tab>. gdb completes the function name and adds on the parameters list and even puts the final single-quote at the end of the line:list 'classname::functionname(paramater list...)'
...but when I press enter I get an error message stating that "classname does not have any method named functionname" which seems like a strange complaint considering that gdb did most of the typing.
Similarly, trying to set a breakpoint at the top of this function yields this:"Make breakpoint pending on future shared library load?" As an aside: I am compiling all units with the -gstabs flag ( plain ol' -g didn't seem to get the job done.)

I'm reading up on some DNS and this section mentioned a /etc/named.d directory. I can't seem to find it - i have bind installed and i've searched on this directory, and the only realistic mention of it is from a post in a blog from 2001. I'm working in a FC12 environment...

i have a host file called myhosts.txt as follow:
Quote:
10.20.3.9 host1
10.20.3.10 host2
10.20.3.11 host3
[code]...
In my script, i am using NSLOOKUP to get the ip address of a host that just rebooted and connected to my network (this part has been done).But now i want to check the myhosts.txt file if the host has the same or different IP address, if is different then myhosts.txt file must be updated with the new IP.i am using the following AWk command:
Quote:
awk '/host4/{$1=val}{print}' val=10.0.3.4 /tmp/myhosts.txt
it prints on screen fine and i see the host4's ip address gets replaced but the actual file does not get updated with the new IP. I might need to use gsub?

I have written a daemon server. I would like to add the ability for the daemon to update itself. That is, it should be able to download the latest version of the code (when it receives a signal from a client) and then restart itself. I am stuck on getting the daemon to restart itself. The problem is killing the old daemon without killing the process that is starting the new daemon. In my latest attempt, the daemon that is updating itself runs a program in a subshell (using system) that starts a restarter daemon that runs the original daemon (again using system) with the restart command option. With the restart option, the new version of the daemon sends a terminate signal to the old version. Obviously, when I run the original daemon manually with the restart option, it restarts reliably. I figured that issuing the same restart command from a daemon would adequately isolate the process doing the restarting from the program being restarted. Using ps, I can see that the daemon does actually restart. However, the client locks. In fact, a few times, the OS locked and I had to reset.

Why is freetype 2 put up as libfreetype6 ? What's the history/reasons behind the same ? This is the way it looks in my shell.
$ aptitude show libfreetype6
Package: libfreetype6
State: installed
Automatically installed: yes
[code]....
I am simply not getting it . Also would it mean that in future, freetype 3 (whenever that becomes/happen) it would be named as libfreetype7 or what ?

We have a MS Windows domain in our school. Some time ago, when I was toying with an earlier version of Opensuse, I joined a box to our domain. I am trying 11.2 now, and my box is box is being named automatically, to what I named the previous box (which is long gone). I guess this is an issue with my Windows domain controller, but I'm not sure what to do about it. The domain controller is running Windows Server 2008 Enterprise.

I am running opensuse 11.0 on Intel Quad computer. A month ago I have installed DNS service on it.
Since then I have a following problem - sometimes named starts eating 200% of CPU and that causes LAN to hang down. Everything goes normal after named restart.

One of the dedicated servers that I have does not seem to have the service 'named' functional:
root@server2 [~]# service named start
Locating /var/named/chroot//etc/named.conf failed: [FAILED]
Note that the double slashes (//) ARE part of the output as well as the long gap before [FAILED] appears. This 'named' service not being functional is not a problem which is preventing the server / the application on it from working. There are entries in /etc/resolv.conf though.
