Networking :: Raw SCTP Socket Cannot Bind With Port?

Jul 26, 2010

If I open a raw SCTP socket, am I able to bind to a specific port? (I only want to see SCTP packets from a particular IP address AND port.) Or, any raw SCTP socket, regardless of port binding , will get all SCTP packets received by the OS from that IP address? The port doesn't matter and is ignored.

Fedora Networking :: Don't Seem To Get Our Bridging With Protocol

Jul 12, 2011

We are running in to a issue where we don't seem to get our bridging to work as we expected. Meaning passing all traffic from Point A to Point B. As explained below:


This is the original connection. Now we are adding our Linux IP impairment box for IP tables in between Application Server A and Router X so the figure would look as below: Application Server A --> IP Impairment box --> Router X --> router Y --> Application Server B

The issue we are having is When a packets are sent from Server A to Server B they are going through for PING, TCP, UDP, but for BGP the connection is established at a TCP level (SYN, SYN-ACK, ACK), but the BGP OPEN packet does not get through and our BGP relation ship does not come up between Application Server A and B. Application Server A and B are a routers also but there are applications running on those router. BGP is underlying protocol used for Application Server A to be talking with Application Server B and getting routes for each other.

Even with the iptables empty (all rules default ACCEPT) we still can't seem to get these BGP OPEN's through. We see both sides of the application servers sending BGP OPEN's, but the Linux bridge never passes those packets to the other side of the bridge. Tracking the BGP packets, we see the packets at iptables raw PREROUTING and filter FORWARD tables but the packet doesn't get out the other interface.

Ubuntu Installation :: Error: "Network Autoconfiguration Failed. Your Network Is Probably Not Using The DHCP Protocol

May 21, 2011

I recently purchased a Dell Vostro v130 which came with Win 7 pre-loaded. I've been using it for a few weeks with no problems, but now I'd like to install ubuntu studio. I made it through the the partitioning part but now I'm getting a networking error: "Network autoconfiguration failed. Your network is probably not using the DHCP protocol. Alternatively, the DHCP server may be slow or some network hardware is not working properly."

I've been using the wireless connection in win 7 without any problem so I don't know why I'm having a problem now.

Fedora :: Network Time Protocol Part Of Date / Time Settings

Oct 3, 2009

I've got fedora 11 set up to use network time protocol to sync my laptop's date & time when I'm on-line. The question is simple really, I've added a local universality's time server (what is public) and it's live. but it's added to the end of the default time servers what come with fedora. How do I get fedora to just use the local time server, is it a case of removing the default time servers for fedora, but there is a box what says advanced options which are. sync system clock before starting service ???? & use Local time source (( is that the same as the local ntp server that I've got set up ))Hope some body can help me with the network time protocol part of Date/Time settings.

General :: The '-p' Option Is Not For A Network Port But For A Protocol

I'm confused as to what protocols 50 and 51 are.

-A RH-Firewall-1-INPUT -p 50 -j ACCEPT
-A RH-Firewall-1-INPUT -p 51 -j ACCEPT

The '-p' option is not for a network port but for a protocol. I've never heard of 50 and 51 protocols.

Fedora Networking :: Bridged Networking And NetworkManager - No Network Connection Because Network Isn't Managed

Mar 2, 2011

I have installed qemu/kvm and created a Bridged network connection which works just fine(Windows 7 VM won't work in NAT mode.)

But when I try to use NetworkManager it says that I have no network connection because the network isn't managed, (I set the settings in ifcfg-br0 and ifcfg-eth0 to be managed)

The real problem is that now I can't use my VPN connections (I have many) in NetworkManager.

Is there a way to have both of these pieces of functionality?

I am using FC14

Ubuntu Networking :: Which File Sharing Protocol?

Nov 30, 2010

I have a small home/office network, which currently consists of a very old mac running osx10.4, a windoze 7 laptop and an ubuntu 10.04/windoze vista laptop, along with a homebrew setup on a wii which understands smb. I'm in the process of setting up an additional ubuntu PC which will, among other things act as a file and web server, mainly for web development and for sharing files, music and videos.

Up until now I've just run everything on SMB, and I will have to set samba up on the new server, but I would prefer to use a different protocol for the ubuntu and mac systems, as SMB doesn't recognise/create file permissions properly and it takes a while sometimes to notice new files in folders it's recently looked in.

Networking :: Write A New Protocol On Transport Layer

Jul 23, 2010

I want to write a new protocol on transport layer. These are the features that new protocol should include:

-Real time
-Concurrent transfer
-Multipath and Multihoming

the reason why i should write this protocol is in order to transport encoded video stream over 3G link. When i investigated TCP UDP or SCTP source codes, i couldnot understand them at all. What ı want is to help me about steps of the protocol writing or guideline about it. How should i start, is there any book or source about it (i couldnot find over my internet research).
