I am using a NanoStation 2 in Router mode.The NS is connected wirelessly to my neighbor's router and a switch is connect via ethernet to the NS for LAN use.
The past few days I'm trying to use a VoIP client software to connect to my VoIP account.I use Ekiga Softphone to do so, which requires UDP ports 3478-3479 and 5000-5100 to be open.
So I have opened these ports both on my neighbor's router and on the NS.The problem that I'm encountering is that although I manage to register to the VoIP service, when I answer an incoming call the caller is able to hear me, but I'm not able to hear the caller.So I used wireshark and figured that there is no incoming traffic on my end.
I have used many linux VoIP clients with PCs connecting straight forward to an ADSL router and worked perfectly.
After I installed Lucid on my Netbook, I have different problems with ekiga.
First of all, some information about my ekiga account:
In ekiga I created a SIP-Account with a usual landline phone-number, my voip-provider is 1&1 (in Germany). In ekiga the account is named "Standard%limit", because I cannot register my sip-account without the "%limit". If I leave the "%limit" out, I get the message "Could not register (Forbidden)", but here on ubuntuforums (or maybe on launchpad) I read about the "%limit" as a workaround. Maybe it has something to do with my problem, I don't know.
Now, this is my problem:
Ekiga does not accept incoming phone calls after a few minutes after launching ekiga. Well, let me describe it this way: Usually ekiga plays a ringtone and shows a message whenever there is an incoming call. However, ekiga only behaves as described and expected just after launching ekiga. A few minutes later, lets say five or ten minutes, ekiga does not accept incoming calls anymore. I tested it with my mobile phone - when I call myself on the landline with my mobile phone, I expect ekiga to play the ringtone and show a message that there is an incoming call. However, ekiga does not do anything and after a few seconds the call is terminated automatically. But it is not the same as if ekiga is not running because if ekiga is not running I get the message that the subscriber is not available.
I have a router which makes two ppp connections. PPP0 is my default route and is an uncapped ADSL. PPP1 is a Local Only (South Africa) account which has DNS resolving to its IP. PPP1 allows certain connections in. I want all packets coming in on PPP1 to be marked so that after they have been routed through our local servers they can go back out over PPP1. Both connections use dynamically assigned ip addresses. I want to use PPP0 to make a connection to one of our stores, but when our stores connect to us they will be using PPP1. All packets from these incoming connections will need to be routed back over PPP1.
Pinging out from my netbook (over wifi, to any host) gets ~0% packet loss. Pinging into it (from any host) gets about 50% packet loss.
The router is a Dlink-DIR615 (rev d, running DD-WRT v24-sp2) but all other hosts on it ping eachother fine. I've tried changing routing, disabling IPv6, using older kernels and using wicd, all with no luck. The wireless connections is at 100% most of the time. This could be a new problem with Maverick, but I may not have noticed it before. I believe this is causing web browsing to be really slow and causing SSH timeouts.
I haven't tried madwifi drivers or nsidwrapper yet.
Edit: just booted into Windows and it has the same problem. Could it be a hardware issue? Also tried with a static IP, with no change.
Strangely, a normal ping gets 50% packet loss, but ping -A gets < 1% loss.
Edit 2: no packet loss at all on eth0.

I have a server that I can only access via SSH (it's located far away) and I would like to secure it by blocking all ports except the ones that I need (which are HTTP and SSH). I still want to be able to make outgoing connections to enable software updates and other things.This is my iptables -L -n :
Code: Chain INPUT (policy ACCEPT) target prot opt source destination ACCEPT all -- 0.0.0.0/0 0.0.0.0/0 state RELATED,ESTABLISHED DROP tcp -- 0.0.0.0/0 0.0.0.0/0 tcp dpts:1:21 DROP tcp -- 0.0.0.0/0 0.0.0.0/0 tcp dpts:23:79 DROP tcp -- 0.0.0.0/0 0.0.0.0/0 tcp dpts:81:65535 code....
In my opinion, this should block all incoming packets except the ones on port 80 and 22, but allow responses to outgoing connections. But a wget http://google.com does not work, it can't establish the connection.
Maybe this is not the best style for iptables rules, but I want to be absolutely sure to not accidently lock myself out from SSH, so I chose not to configure a "block-everything rule".
Does this configuration not enable incoming packets from connections initiated from inside?
i have a linux server runnig oracle applications. i need to access this server from putty using ssh through internet. i did by registering my static ip with the dnydns.org and i am able to connect to the server. but now there is no security to authenticate any user as any one knowing the password can login to it.
i thought of configuring the firewall of linux server but the client ip`s are not static and they change continiously. so thought of keeping one more pc between the server and the router which will do the work of authenticating. but i am confuse as how to configure it to allow the packets coming from the internet after authenticating and to by pass the packets generated from internal LAN?
I have recently installed ubuntu 10.04. The distro seems so much better than that I have before (8.1). Anyway after some days of trying I can say that ekiga doesn't work with 10.04. While I was perfectly able to use ekiga with 8.1, the 10.04 gives me connections problems.... it simply say says "Could not register (Failed)"
how to set a sip account (sip.12voip.com) with empathy??
I'm trying, reeeeally trying to use Ekiga. But the video quality is horrible. So I started messing with the settings, lo-and-behold I find info about h.264 and how fantastic it is. Well, I say to myself, let's try that on for size.
What? No h.264 option in Ekiga. That's weird, especially considering they have supported it since 3.0 and I'm using the version in the Karmic repos, 3.2.5. Not free, ok, I'll just install it then, right?
x264 package didn't do it. A little ffmpeg install as well. libavcodec52, which uninstalled a buttload of other stuff also. Even dl'd and installed libopal3.6.4-plugins-non-free. All to no option for the h.264 codec option in Ekiga.
Oddly enough, the libopal non free plugins DID add the iLBC audio codec into Ekiga as on option. Why not h.264? What am I missing? Also, why is this SO difficult? There is not any decent documentation that I can find out there that goes over this. Google has failed me.
All I have in the video codecs is theora and h261.
When I click on the Ekiga menu-item it seems like nothing is happening. So I went into htop and saw the process is running. When I start Ekiga from the command line, nothing happens as well. Then I tried starting Ekiga in debug modus with option -d 5. Still nothing showing up. When I call my VOIP number I can see a call coming in, however there is no ringing sound and no dialogue to pick up the phone.
Then I re-installed by 'aptitude purge ekiga' and then 'aptitude install ekiga'.
I am working on Ubuntu Karmic. The Ekiga version is straight from the repositories: Version: 3.2.5-1ubuntu1.
I'm trying to set up Empathy to connect to my Ekiga account, so I don't have to have two programs running side by side, but I'm running into some trouble.
In the window for adding accounts in Empathy, there's a drop-down menu for choosing the desired protocol and service. I hear there's supposed to be en "Ekiga" menu option there, but there isn't.
I am using ekiga 3.2.7 on Natty and I am able to make pc-to-phone calls but I am not getting any sound on my speakers. The person on the other line is able to hear me, but I cannot hear him. Does anyone know what the problem might be?
I have recently installed ubuntu 10.04. After some days of trying I can say that ekiga doesn't work with 10.04. With the same computer I was perfectly able to use ekiga with ubuntu 8.1, the 10.04 gives me connections problems.... it simply say says "Could not register (Failed)".I'm trying to connect with my voip provider (12voip.com) but it seems that I can't. I have even tried other programs like empathy, Twinkle, QuteCom but with none of them I can connect with my voIP provider. I think there are some connection problems but I really don't know how to face them. We have to configure router in 10.04 for sip connection? Actually I can't phone at all.
I have an Acer Aspire One netbook and have tried to enable my microphone without any luck. Surprisingly the Sound Recorder works perfectly but skype and ekiga are not able to transfer my voice. I have tried playing around with gnome ALSA mixer and PulseAudio Volume Control but nothin changes.
I am not getting very good sound from skype. I wondered if Ekiga was better than skype so I have:
Installed it. Obtained a sip address. adjusted the ports on my router as below set up the user by way of the configuration assistant.
And still I see nothing and hear nil. I am not getting an error message. When I run the test address it immediately reports it is done. I set up the H232 account.
Each of the following port ranges were translated to the same ranges: TCP 1720-1720 UDP 5000-5100 TCP 30000-30000
I have a hardware device with two ethernet ports, eth0 and eth1 running Centos 5. Basically my goal is to forward packets from eth0->eth1 and eth1->eth0 as well as get a copy of these packets for analysis. If I set IP routing to do the forwarding then I won't get a copy of the packets for analysis.
After timeout is over a SIP account does not register again automaticaly, manualy can be unregistered and registered again. Changing timeout seconds does not make any difference, re-registering does not happen. Is there is a way ekiga can be forced to re-registered itself automaticaly?
I am trying to use ekiga on fedora 10 with a windoz pc running netmeeting. The windoz pcs can talk / see each other on netmeeting. But when I try from my linux box (using this as the address "h323:192.1.1.12" ), I get connected but the window shows my own local end video and there is no voice even from the other side. The other side gets my call notification and on accepting the call doesn't observe / hear anything either. Can someone tell me where is the problem ?
I had tried searching the forum for related sound help but to no avail. Thus i posted here in hope to get help.
I had been using fedora 12 since it release and been working wonderfully. Untill my last 2 update, my Voip softphone like twinkle, ekiga and linphone somehow have no sound out from speaker.
1. i can play all video and music with sound coming out from my laptop inbuilt speaker.
2. for twinkle, ekiga and linphone, there's no sound out from my laptop inbuilt speaker.That means, when i call a person, that person can hear me talking (my mic working good) but when he talk i am unable to hear him as no sound coming out from the speaker.
Note: i had call multiple different people and the result is the same.
I am on Gnome desktop with PusleAudio install and running since the releae of F12.
Skype works fine on openSUSE 11.2, but I'd like to use another application with a more open protocol (SIP) for PC-to-PC calls. Ekiga seems to be what I'm looking for, but I have a problem with audio. When I launch the echo test call, video is displayed correctly (I see myself), but I can't hear anything (I guess I am supposed to hear a ring, and maybe some instructions?...). Nothing seems to be recorded either. I tried all the different audio settings in Preferences/Audio - no luck.
I searched for some information on the web but couldn't really find anything. The troubleshooting test (arecord -D plughw:0,0 -c 1 -r 8000 -f S16_LE - | aplay -D plughw:0,0 -c 1 -r 8000 -f S16_LE -) from [URL] works fine. So what to look for? Does anyone here use ekiga successfully? How did you configure your audio? Or would you recommend another SIP client?
I just download source code of ekiga at address [URL]. I want to develop it, I compiled it in ubuntu successful, now I want to develop it in window platform by visual studio 2008 but I don't, can I can make environment for window and import it to visual studio 2008 to debug.
i just had to switch from 10 to 11 until 12 comes out, and after setting up asterisk, i noticed VERY VERY BAD sound quality, mostly comprised of severe jittering. I noticed that the way Fedora lets you work with your sound devices in 11 is way different (nicer, but obviously not complete) than ever before, and i am using the same asterisk configs as before, so i'm positive that this is NOT an asterisk issue, and does NOT really belong in this forum; however, only asterisk users will be able to replicate or identify with this issue.
Have any of you 11 users had this happen to you, and if so, did you figure out how to solve it? I'm sure that i can *try* adjusting asterisks jitter buffer settings, but like i said, it was NEVER an issue before 11... Another clue would be that i cannot get crap like gtk-recordmydesktop to produce sound (but that may very well be another issue; however i doubt it)...
I was looking for a software to use for VOIP calls and I tried Ekiga (since Empathy does not seem to work at all for VOIP) I installed, checked the sound settings and all worked fine. I setup the first account I have with my SIP provider and it worked fine. The I setup another account I have with the same SIP provider. The settings have been tested time and time again and they are correct. Both account work perfectly on a windows machine with X-lite, but on Ekiga, with the second account, I cannot make any calls because I get the "security check failed" message. yet the settings are correct and they are the same for both accounts (apart from username and password of course). Unregistering from one account and registering into the other does not make any difference. It just does not want to play nice. if anyone has a better suggestion for VOIP calls.
I need some suggestions on software. I would like to offer remote desktop support to some of our clients, but some of them are using ISP's that block incoming connections so, VNC is out of the question. I was wondering if there is something similar to logmein for ubuntu?
I'm trying to block an incoming URL. My ISP is hijacking 404 pages and annoyingly changing the URL line in the browser and flashing all sorts of popup ads. I just need it for incoming URLs which my router doesn't seem to handle. I'd prefer something packaged with Ubuntu 8.04, but anything simple will do. I know in KDE I could edit the kdeglobals file with:
I am setting up a server that is to serve websites and host mail.I have run into a problem regarding the mail server. The server is completely set up but for some reason it is not receiving the e-mails I am trying to send to it. When i mail to the associated mail address from internal by the "mail" command it works fine. But when I try from an external mail server, the mail never gets through. And I do not receive a bounce e-mail.
It says that the port 25 IS open for TCP connections (in iptables - I opened it myself). And surely when I telnet to it on that port from inside the server, I get an connection. But when I telnet from an external network I get a refused connection. It would sound that the port is in fact not really open for external use, in my mind, but it is. Is there possibly anything else I might have neglected to check in this mystery
