Networking :: Opening Ports On Slackware?
Jun 20, 2010How can I open a p[ort in slackware? I am "trying" to install and use Alfresco, a DMS that runs on linux platforms. So far that has been a nightmare........
Basically, according to their support tech, port 3306 is blocked. I dont really understand because I have MySQL DB server running and listening to 3306 on that machine and no problems at all... However, they recommended to try:
Code:
telnet localhost 3306
or
Code:
telnet <machinename> 3306
but it resulted in:
Code:
telnet connect to address 127.0.0.1: Connection refused
If I understand correctly , the Alfresco support is correct, 3306 is indeed blocked. But how come mysql is running fine then? How can I unblock this port? And finally, I need to specify that I dont have ANY type of firewall or anything like that because this machine is not connected to the web... So if I dont have a firewall , what is blocking the port?
Software :: Shorewall And Opening Certain Ports?
Aug 27, 2010I have searched the web for this answer and i can't find it. I'm using Shorewall for my company firewall and all is working well. But i need to tweak down a few problems that i have. Employees have internet connection over a proxy server (http and https traffic), but some do need to connect to other ports not through proxy but directly. I want to add a exception to the rules. For example i want to allow that a local ip can connect to a predefined ip on the net to a specific port. All my attempts have failed.

Aug 30, 2010I am trying to open a tunnel for a friend of mine who's isp has blocked a bunch of webpages, so I was thinking I would learn how to since it might come in handy in the future Anyway, so I looked at a couple of videos about going in to network settings and changing the setting to manual and write down the desired IP (in my case 192.168.0.137). Then I went into my router (it's a D-link DI 524) and tried adding my static IP as the DMZ computer. I then restarted, everything looked fine, the router saved the settings and the eth0 still hade the information saved so I wanted to try it out. I just googled "try my ports" and I found a website called [URL]...But no ports worked for me.. I tried double checking everything, checking for errors. I couldn't find anything so I'm guessing you might have a clue!
EDIT: It seemed I had to have a program that actually used the port for it to work.. It's working anyway, so if you could move it to [SOLVED] I'd be happy
Ubuntu :: Accessing Parallel Ports From Perl Program
Dec 11, 2010I am trying to write to the parallel port pins from a Perl program running Ubuntu Linux, to light up led's on a bread board. I've already accomplished this on this same box using a C program, but I cannot get my code below to work. I believe the problem is with the line:
$parport = Device::ParallelPort->new('auto:0');
I've tried different variables between the ('') ticks, but nothing has worked. I use Perl on my web pages for forms, but this has stumped me.
Code is below:
#!/usr/bin/perl require "subparseform.lib"; &Parse_Form; print "Set-cookie:
cart_id=1234; user_id=123;
"; print "Content-type: text/html
"; use strict; use CGI; use Device::ParallelPort;
# use Device::ParallelPort::drv; # use Device::ParallelPort::drv::linux # use Device::ParallelPort::drv::parport
# Set up your parallel port object and tell it what driver to use.
#my $parport = Device::ParallelPort->new('auto:0'); print "It works!!!";

Networking :: VoIP And Opening Ports With Recommended Settings
Nov 7, 2009I have recently bought a IP/PABX system with one FXO and one FXS port. I intend to install this on a remote site with a public but dynamic IP (can be resolved via dyndns though) and make calls via clients that are NATTed (inside a home router). I would like to seek advice on the port opening and the recommended settings. I have been reading a lot on VOIP and I am getting feedback that SIP calls are difficult to establish on a NATTed environment.
1.) SIP port 5060 UDP?
2.) RTP ports - what range should I open for this? I see some use 10000-20000 UDP
3.) STUN server - Is this something that needs to be configured?
How can I ensure that the other party can hear the audio just like a regular telephone? Is it really impossible to do if the client is behind a router in which it is using a Private IP Address? What other network configurations needs to be done?
Ubuntu Servers :: Secure Fileserver Over Internet - Opening Samba Ports Make Default Particularly Vulnerable To Penetration?
May 26, 2011I'd like to set up a fileserver for myself and a few trusted individuals. I'm computer savvy and I use various linux servers frequently for work, but this is my first time trying to setup my own. Is it possible to have a Samba server setup so it is both secure and facing the Internet? Two questions:
Will opening Samba ports make my default Ubuntu server particularly vulnerable to penetration? More than having an SSH server running? Does Samba/ can Samba be configured to encrypt traffic or is it sent plainly? If so, does Windows and Mac support this secure communication?
If not, what would you suggest? I'd like to achieve something like a network drive and at a difficulty level that my parents could use this if they really wanted to. I will be storing things like financial information and tax returns, but no weapons-grade secrets.

Dec 23, 2010I am using a C application which connects to various other C applications at different ports through TCP,sends requests to all of them and then waits for the responses. The problem is that when the requests are fewer it gives a good response but with the increase in load the port at which the master application is listening get hogs and is unable to receive the responses.Can you please suggest the best way to tackle this issue? Is it possible for the master application to listen at multiple ports so that the load gets distributed and how?

View 8 Replies View RelatedProgramming :: MP3 - Tag And Perl Script
Mar 27, 2011I am a newbie on linux and just searching everything about perl scripting and modules nearly 3-4 days. I need a perl script but one of not easy to find on searching google. Okay now I need a perl script which create or recreate (edit) id3 tags (artist, comment, album, year, cover) of mp3 files stored on my linux centos server. I installed MP3::Tag version 1.13 pearl module to my server. I Searched tutorials about how to use it, finally I get through reading id3 tag of mp3 file but not achieve to modify it or create a new id3tag.
These are the details:
I have a mp3 file called 1.mp3 this script will process that '1.mp3' file read its id3tag if there is one, than modify or create id3tag for it by my fix artist name for example:
'1.mp3' files id3 tag details are like this
Artist: Dj xx
Year:2010
Title:yyyyy
Comment:eerwer
Cover: x.jpg
Now via this perl script which uses MP3::TAG I will change it's
artist as YYY
Title:ttt
Comment:cool
Cover:t.jpg
these are gonna be my fixed values. I mean all '1.mp3' file will have same artist based on script value.
The reason of this script is I will share Dj podcasts on my server and Dj's would have upload their mp3's which has got different id3 tags and cover pics. etc. I want to create more organized podcasts of them by the way I would trigger this perl script via Cronjob.
