General :: Xinetd Server Configuration - Infinite Loop?

Apr 14, 2011

I have a java server console program that I have configured xinetd to start when connection comes in on a given port and then the program runs in an infinite loop receiving inputstream from telephone exchanges. The thing is, when a new chunk of stream comes from the exchange xinetd forks a new process each time. I tried setting the wait parameter to yes and restarted the deamon, but no success. How can I stop this behavior and have the deamon just direct the stream to the process already running? Am I missing something in my config or is it just incorrect?

My config is as follow:
defaults
{
instances = 60
log_type = SYSLOG authpriv
log_on_success = HOST PID
log_on_failure = HOST
cps = 50 10
}
includedir /etc/xinetd.d

And then my actual config,
service aos_larmar
{
socket_type = stream
protocol = tcp
user = root
type = UNLISTED
wait = yes
instances = 256
server = /home/gunnl/java/start.sh
port = 5204
disable = no
}

My server OS is, Red Hat Enterprise Linux ES release 4 (Nahant Update 7)

Programming :: Infinite Loop That Isnt Infinite?

Oct 27, 2010

i was playing around with c++ recently and for laughs and giggles i came up with this little program

Code:
#include <iostream>
using namespace std;
int main ()
{

[Code]....

theoretically that should be an infinite loop but it in fact does terminate eventually echoing out 'FIRE!'

just wondering if even though in theory this should be an infinite loop (a number repetedly divided by 2 should never reach 0 thus the conditions of the loop should never be satisfied, hence infinite loop) perhaps in practice limitations of the variable types prevent this?

Slackware :: EQ Overflowing Server Is Probably Stuck In An Infinite Loop?

Oct 28, 2010

It happens really randomly. Suddenly keyboard and mouse stop to react. Screen freezes. However if I have for instance skype running during that "crash", I can still continue to talk over internet. For me looks like x serwer crash. Xorg logs however are empty. I had to hard reboot only to get control over pc (magic sys key + SUB) only works. Trying switch to another session is not working. I run Slackware 13.1. Kindly asking to help me to solve that irritating issue. I pasted errors usually I find at Xorg.0.log.old after hard reboot only

Code:

Debian Multimedia :: X.Org Infinite Loop Bug In Squeeze?

Mar 25, 2010

I think i came across a bug in X server in squeeze. I would report it to the bug tracking system in debian packages but the think is I am not entierly sure about it.When i start X (whether it is through startx or service gdm start or auto startup through init when the pc boots) the computer PC seems to lock up.The screen goes black right after X initializes and before anything is show in the screen and if i wait a about 10 minutes the monitor either goes in standby or out of range. PC seems unresponsive to both keyboard commands and mouse but my LCD screen in my G15shows the time skips 1 sec every 2 sec (from 19:22:22 goes straight to 19:22:24).

I have a custom 2.6.33 kernel which i build but it happens with both 2.6.32-trunk and 2.6.32-3 offical kernels from the squeeze repository so i dont think that this is the problem.My PC is a P4 3.75Ghz with 2Gb RAM and an NVidia 6800GT with the binary drivers from nvidia. I have tried diffrent versions from my grapgics drivers (NVIDIA-Linux-x86-173.14.25-pkg1.run & NVIDIA-Linux-x86-195.36.15-pkg1.run) with no change in the behaviouThis is the syslog from the time my pc started and then "stuck". I left it for some time before i hard reset it

Software :: Detecting An Infinite Loop In A Process?

Apr 1, 2011

I am trying to develop a process monitor, or use existing monitors to achieve the below given actions.

1) Restart a processes if it crashes.
2) Restart a processes if it is stuck in an infinite loop.

The sample code below describes the structure of the process.

while(1)
{
statement 1....
statement 2....
while (1)
{

[Code].....

The goal is to restart the process if it is stuck in a loop, inside the outer while loop. Given this scenario, what would be the most efficient way to monitor such a process?

A sample solution would look something like this: statement 3 will write to file1 every time it is executed and we know that the maximum execution time of the outer while loop is 30 seconds. A second, timer driven process, checks for file1 being modified every 30 seconds. If the file is not modified, process 1 will be restarted assuming, process1 is stuck in a while loop.

Ubuntu :: Infinite Boot Cycle Loop After Grub

Jan 26, 2011

When I boot one of my machines, it gets as far as GRUB, then proceeds to a blank screen for a second, and then repeats the cycle all over again - ad infinitum. I have tried previous kernels on the list with the same results Also, I cant boot into recovery mode either.

I have run Memtest successfully from the GRUB options and no errors appear in the results. I have tried booting from a Live CD and here I get as far as the "OS choosing screen". When I then select one and hit Enter, the screen goes blank and the machine reboots as before.

I can go into safe graphics mode and things look fine except compiz isn't running. I have tried going into login and changing it to log me in automatically but the problem remains.

I've tried using my previous kernal and I have the same issue as this newer one.

I've tried loading gdm from CLI and the problem is still there.

Ubuntu :: Infinite Startup Loop - OEM / Black Screen

Apr 18, 2011

I'm doing a dual boot Ubuntu 11.04 and Windows 7 on my Asus UL80v. When I restart and keep going into Ubuntu I'm fine, but I think if I go to Windows and then restart, the infinite start up happens, and I'm currently stuck in this. It'll go to the OEM screen, then a black screen with a cursor, then it goes black, and then back to the OEM screen and so on and so forth.

Luckily I have Ubuntu 10 on my flash drive, so I'm booting to that while I try to figure out this. Which reminds me, when I use the flash drive, there's an option to boot to local disk which also does not work, if that's worth anything. Before this happened, I ran check disk on windows because I ran into some partition troubles. There seemed to be no problems, and I can still access the drives from this flash Ubuntu.

Ubuntu :: Printing Gets Infinite Loop Of Blank Pages?

Jun 25, 2011

I installed Xubuntu and was thrilled to see that it had already setup my Brother HL-2140 USB laser printer.However, there is something seriously wrong with the setup. When you try and print, even a test page - it just churns through the entire paper tray printing nothing. Also, when you restart the computer it tries to print the jobs again. I went to Printing and selected the printer but could not find where you could see the print job queue. I did see it during troubleshooting and was able to delete the jobs on the troubleshooting screen.

Fedora :: Stuck In Infinite Loop On Login After Changing Wallpaper?

Aug 17, 2011

Fedora 15, fresh install.I changed the wallpaper from default to a solid colour. After switching between gradient to colour the system crashed logged me out and upon logging in it simply runs endlessly accessing my harddisk but never actually loading the desktop.I can kill X and reboot, but it's the same problem waiting for me on restart. I really don't want to re-install or delete users (to put it in context, I just spent 3 days trying to install Fedora because Anaconda doesn't know how to install GRUB correctly).

Ubuntu Installation :: Screen Shell Goes Into An Infinite Loop After Upgrading To 10.10?

Oct 20, 2010

I have just upgraded from 10.4 to 10.10 (x64), and now when I run gnu screen the new shell session goes into an infinite loop displaying:

Quote: Linux dave-desktop 2.6.35-22-generic #35-Ubuntu SMP Sat Oct 16 20:45:36 UTC 2010 x86_64 GNU/Linux

Welcome to Ubuntu! * Documentation: [URL]...

0 packages can be updated.
0 updates are security updates.

repeatedly until I hit CTRL-C and break out of screen. I tried tmux and that did the same thing, so it is a problem with the shell initialisation rather than with the screen program. However I can start bash, zsh or sh directly in a terminal with no problem.

Server :: Run /usr/bin/foo Through Xinetd ?

Apr 28, 2009

If i run /usr/bin/foo through xinetd and have /etc/xinetd.d/foo conf file something like:

2 {
3 port = 3691
4 socket_type = stream
5 protocol = tcp
6 wait = no
7 user = www-data
8 server = /usr/bin/foo
9 server_args = -x
10 }

Is /usr/bin/foo supposed to be listed in the list of all processes on that machine (ps aux)? i added the conf file, bouced xinetd daemon via /sbin/service, yet foo does not seem to be running. the xinetd doc online seems pretty incomplete.

Server :: VNC Over Xinetd Doesn't Starts Vncserver

Nov 26, 2010

in Debian Lenny, using TightVNC 1.3.9 I can setup a VNC server manually by using

Code:
vncserver -query localhost -once -geometry 1024x768 -depth 16 :1

But then, as I have read is a better option, I use xinetd with the following configuration:

Code:
service vnc-1024x768x16
{
protocol = tcp
socket_type = stream
wait = no

[Code].....

In fact, I was considering that the problem was with xinetd, but I have other services setted up with it (telnet & ftp for example) and I can use them correctly.

So now I'm lost with this, what else am I not considering with VNC service through xinetd? Where can I find logs or useful information to get a clue about this problems?

CentOS 5 Server :: No Xinetd Installed By Default?

yesterday I installed my first CentOS system. Before I was always using Debian for my servers. When I configured my vsftpd I was just wondering how to setup xinetd or inetd for listening on ports and starting vsftpd. I found /etc/xinetd.d. But there is no xinetd installed by default. Why? Shall I start all my services in standalone mode? What is the concept of CentOS in this issue?

Server :: Configure Fakemail To Startup As Xinetd Service?

Feb 2, 2010

I found a way to capture emails sent from my Drupal installation, and Fakemail seems simple enough. I can follow the tutorial. Since the application Fakemail needs to be running to capture the outgoing emails, it seems like a good candidate for xinetd, yes? I've found a simple config tutorial describing starting the service and what the parameters are for the service-specific configuration files. This got me this far,

Code:

# default: on
# description: This is a script to start the Sandbox app "fakemail"
service fakemail

[code]....

But the service is not starting up. Will someone help me with this config file? Or, recommend another application which uses a similar configuration like Sendmail so I can copy this The Fakemail application/service is started from command line like so,

# fakemail.py --host=localhost --port=10025 --path=[path_to_email_textfile]
