Hello list ! I'm having one way audio on incoming and outgoing calls. Outgoing audio works fine, incoming audio is not working. My setup is the following : incoming calls : PSTN -- FXOport -- HT503 -- WANport -- Asterisk -- WANport -- HT503 (the same) -- FXSport -- DECTphone outgoing calls : DECTphone -- FXSport -- HT503 -- WAN-port -- Asterisk -- internet (VoIPprovider) I've done a

After getting a reasonably configured NFS4 setup working on my Scientific Linux server, I spent a majority of my evening trying to do the same with my Centos 5 box, with fruitless results. Most attempts to mount that server returns the following message: [root at sl01 log]# mount -t nfs4 192.168.15.200:/opt/company_data /mnt mount.nfs4: Operation not permitted As nearest as I can tell, I was

Hi all, Asterisk is great but I'm having issues with setting up realtime for our call center, which is needed for login integration with the rest of our applications (telephonists' web interface, etc.). I have reviewed a large number of previous posts to the mailing list and the voip-info wiki to no avail. Setup is as follows: Linux 2.6.23 (gentoo) / AMD Athlon(tm) 64 Processor 3000+ /

Hi. I have strange troubles with DNATing UDP packets. The situation: 1. We have local network 10.10.0.0/16 2.

There are HW pingers in the net 10.10.0.0/16 whose do ping 10.10.100.1 every second. The ping is the UDP packet

Any help here? I have included all of the output of the suggested diags that Thomas said I should run, but I admit that I'm not sure what I'm looking for, as I'm not familiar with RPC functionality on Linux. Something is not working with RPC on my Samba 4.0.3 server. (FWIW, it doesn't work with IPTables stopped either.) > On Mon, Feb 25, 2013 at 2:21 PM, Mike Stroven wrote:

Hi, experts for example, the below case: You can see a lot of back and forth MTU probe packets been exchanged between tinc nodes, but it’s weird that, from the debug log, one line shows "No response to MTU probes from node1”, but it indeed received a lot of MTU probe response, and finally it get the conclusion of "Packet for node1 (1.1.1.1 port 443) larger than minimum MTU”.

Hi all, Which ports do I need to have open on an NFS client's firewall to allow it to connect to a remote NFS servers? When I disable iptables (using ConfigServerFirewall), it connects fine, but as soon as I enable it, NFS gives me this error: root at saturn:[~]$ mount master1.mydomain.co.za:/saturn /bck mount: mount to NFS server 'master1.mydomain.co.za' failed: RPC Error: Unable to

Found an error or two from my logwatch report from yesterday, thought I would share this in hopes this is just first time run of the problem I noticed in the Kernel report section... Also not sure why there's an issue with automount either.... but I guess I could ask on that issue as well. I am not worried about the NAMED error, this is something that happens due to one of the services that

My firewall config is below... I am trying to figure out why another machine has access to port 5038 on my machine based on these firewall rules. I thought the reject at the bottom would take care of all other ports? It does not. I have restarted with "server iptables restart" and same thing. I can connect from another machine to my machine on port 5038. How do I prevent this?

I have the following scenario: g729 gsm UAS <-----------> * <-----------> UAC I am using sipp to generate the calls between the UAC and the UAS and sending some rtp from the UAC, I want * to do transcoding but as I see it is not.
