How To Setup An Mx Record

we do have a record buffer in awk utility that holds one complete record of a data file.

I want to know that if record buffer changes during script processing, then when are these changes reflected back to the data file?

Are they reflected immediately or is there an in-built mechanism available to schedule this change?

I am able to view my tv@nywhere card with tv time, but when I tried to record with VLC media player I couldn't switch to the proper source. How can I switch the source or what other program can I use with knoppix 7.4. Any advice will be greatly appreciated.
Thanx

I am trying to learn enough to manage my own site using a VPS.

Is there some way to hide who my web host is in the DNS record? (Looking to make things more secure.)

Someone I know mentioned that I should get a "Virtual Name Server (VNS)".

Not sure that I understand what that is, or why it would benefit me.

Anyway, is there a way to make it harder or impossible to know who my web host is?

Sincerely,


Rob

I have got a data file that contains 22 records.

When i write an awk script to compute the number of records, i print the value of NR variable. Why does it show 23 instead of 22?

I get the same output from FNR variable also. So what is the difference between NR and FNR variable?

In the text i found that
NR: gives number of records read- record number in the current file
FNR: file number of records read- a record number in the current file

Hi, for scientific reasons I need to record 8 audio channels simultaniously. The process has to be automated, so I want to run everything from commandline.
The device I'm using is a Presonus Audiobox 1818VSL. Ideally it should feed a RaspberryPi which stores it on a external harddrive. For my porpuse the samplerate doesn't really matter, but the file size should not not be to large. So 16 bit and 4 to 8 kHz would be great.
Up to now I've tried to use arecord with every posssible format, bitsize and samplerate, but nothing worked out so far. Obviously arecord missinterpretes the incoming signal, what results in pretty large and samplerate dependend noise.
Surprisingly everthings fine with the recording via audacity, which excludes the possibility of driver problems or something like that.
Does anybody have an idea how to solve this problem?
Thanks in advance

I remember there is this record that the OS uses to keep track of each file. and if this file runs out of space then we would get this error. but i can't recall the name of it or how to fix it. I think it is called inodes or something like that?

are you guys famaliar with what I am talking about?

I have a nginx setup , and there is a redirect in the config to force https, so if a user enters domain.com, they get redirected to https://www.domain.com .

If a user enters https://domain.com, they get an error , because I have no host A record for domain.com, so I want to redirect https to https://www.domain.com when a user enters https://domain.com .

Dear all,
I don't know how I can figure this problem out.

I tried to execute iozone with clustered mode but it didn't work. It stalled after executing the last line (see below!)
What do you think the problem is?
Please let me know if you have similar experience to me.

Best regards,
Jeongsook.

Ok I'm really new at this . Not the old DOS I'm used to. I'm trying to setup my home server using Ubuntu 12.0.4, I've had no success. I have an actual raid sever I'm using. Loaded first HD with Ubuntu 12.0.4, now trying to setup so I can access from anywhere. Remember I'm a newbie so try and keep it simple until I learn Linux. I have my router setup for port forward using 192.168.100 port 21. everything I looked at so far is pretty complicated for a new user. Any help would be great.

Dear Forumners,

I have implemented as Asterisk solution on two seperate servers and trunked them with IAX2 trunk.

Every morning the servers have to be restarted in order for the trunk to work.

One of the messages I got from the logs is:

Packet too short or invalid while reading response record. (Maybe an UTF8 problem?)

I will be grateful if any forumner can offer me the necessary assistance.

Michael
