Asterisk Trunk Works Intermittently

I have a typical requirement, I want to have a converter module, that can convert UDP packet to TCP packet. And I need to do it before the packet can be processed in IP layer.

I will explain this complete scenario using an example

Lets say we have 3 machines A, B and C.

A sent an UDP packet
B received UDP packet
At B, when packet is being given to IP layer (from Link / MAC / Ethernet layer) , I want to get hold of packet. I want to delete the UDP and IP header in packet. I want to add TCP and IP header (assuming C is the destination host).
Now from B machine, packet is sent to C machine

Can somebody help me how this can be done. I am using linux machines.

Though libpcap can be one of the option (from wireshark), but it is not suitable for me because of performance reasons. I want a very light weight solution for this problem.

Hi All,
Hopefully a simple question to answer. I am going to be setting up multiple Apache web servers behind a F5 load balancer and need to share the documentRoot out to all the servers. I have a dedicated SAN which I want to use and I've been searching to find a concrete document that states if its ok to use an iscsi drive or NFS mounted to all web servers but haven't seen anything concrete to say thats the normal or best practice way to setup that environment. My main concern is writing to the file at the same etc.

Can someone advise what they do for multiple web servers?

Thanks

Hi there. I have Ubuntu 14.04 installed. Actually I have been doing a lot of work in this OS for about a year. The thing I cannot still comprehend is how to find files I installed. In this particular case I need glut.h for g++ compiler. So I go here, do this command;

Code:

sudo apt-get install freeglut3-dev

And find out that I already have the newest version (which I have suspected since I recall installing it).

So, the next step is to find the glut.h file and reference it with #include command. I cannot find it anywhere. This website says it has to be he

Code:

/usr/lib/x86_64-linux-gnu/libglut*

Why's the asterisk? Is it a footnote or part of the code?

I don't seem to have /usr/ directory. I cannot find it anywhere.

How does Ubuntu directory work?

Thanks, - A.

Hello--can someone tell me how to RSYNC bteween two servers with IP addresses, username and passwords while removing the files at the senders end? Do I need to login as root on both servers? I appreciate your input.

I am trying to code a python script that does:- Using root account logs into multiple servers provided in a list. Check the OS type e.g. Linux, Solaris, HP-UX and Windows. Depending on the OS type it updates the name servers and options in /etc/resolv.conf. The update is done from a list that is also provided.

Any help is much appreciated.

Hey all,

I just did a Debian minimal install and am using the package network-manager-gnome to manage wifi. I should also mention I'm running OpenBox. Anyway, network-manager shows up just fine in my systemtray and it lets me connect and displays that I am connected in the system tray. However, when I try to connect to a website it will just say "connecting" for a very long time before timing out. Note that my ethernet works perfectly.

If it helps, this is what shows up in iwconfig after I've "connected" to a network through network-manager:

Code:

wlan0     IEEE 802.11abgn  ESSID:"The Stack Resident Wifi"  
          Mode:Managed  Frequency:5.24 GHz  Access Point: 54:3D:37:02:A5:CC   
          Bit Rate=13 Mb/s   Tx-Power=15 dBm   
          Retry short limit:7   RTS thr:off   Fragment thr:off
          Encryption key:off
          Power Management:off
          Link Quality=33/70  Signal level=-77 dBm  
          Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
          Tx excessive retries:0  Invalid misc:154   Missed beacon:0

I've searched in many places and I couldn't find someone who had a similar problem. Any help would be awesome. Thanks!

I have searched and was unsuccessful in finding a quick command or example to use.

I'm looking to automate an update process using command line in Debian.
Normally I'd use apt-get update|upgrade|dist-upgrade .

If apt-get finds a package to update it queries a Y/n response.
My objective is to have a script determine if this prompt is there, and if so to respond with 'Y'.
If not then it should not enter a response.

I know I'll need to use an IF/ELSE function, but what I'm having difficulties locating is to read the output of apt-get .

I know there's books and sites available, but they are all long and sometimes difficult to read or understand. And maybe my keywords are the right ones to use, as I'm not able to pinpoint a solution.

Thanks for your assistance.

Hi, I can see the below mentioned logs writing every second into /var/log/messages.

"setroubleshoot: SELinux is preventing /usr/bin/perl from ioctl access on the file /usr/share/perl5/Exporter.pm. For complete SELinux messages. run sealert -l e6a1fd7e-a8c0-44bc-91db-b550f85f31c2"

Can anyone help me to find the root cause of this and how to fix it also?

Thanks in advance,

George

hello,
I have a CentOS system and I want to prevent the boot messages from appearing during bootup. I have added the quiet option in grub.conf file which hides the boot messages, but after pressing the esc key or the arrows it shows up again.

Is it possible to hide it permanently?

Or not show the boot logs when the basic(esc or arrow) keys are pressed but assign a different set of key combos which when pressed, then only the boot messages should be visible.

Thankyou

I have a Kubuntu install that works fine but for some reason, it grows the logs into hundreds of GBs.

Is there a method to prevent those logs from growing so large? I researched "log rotate" but I couldn't understand it.

I would like something established such that after a certain size, the logs are automatically deleted so I don't have to do it manually each time.

How would I do so?

Here are the logs:

#1: /var/log/syslog
#2: /var/log/kern.log

I already determined I don't need them, so I would like to auto-delete them once they reach a certain size.

Thank you.
