[ubuntu] Port bonding/aggregation

linux-howto

http://ubuntuforums.org – I've been reading about using more than one NIC on a server and client PC for port bonding. My gigabit switch does not support LACP. I was wondering if it would be possible to connect something in a setup like this: Server NIC#1 ----- Switch ----- Client NIC #1 Server NIC#2 ------------------- Client NIC #2 Note that Server NIC 1+2 are on the same PC, and Client NIC 1+2 are on the same PC. Packets would be sent over the switch on the first link, and direct over a crossover cable on the second. This would create 2x the bandwidth (2 gigabit vs. 1 gigabit). I would imagine this would increase (HowTos)

If I have a network like:

Group1 -> Switch -> Switch -> Server (configured as gateway by DHCP) Group2 -> Switch -----^

(Hope that makes sense...)

When computers in each group send packets to other computers in the same group (so same switch), will the packets go all the way through the second switch to the server and back again or will they go directly to each other via the first s

Redhat bonding with two switch 1 year 13 weeks ago

I have a server with two NICs, each connect to separate switch. Two switches connected with a trunk link. The problem is the bonding link is not stable (lost some packets). When I unplug cable from 1 link, many packets has been lost (nearly 1 packet lost on 2 packets).

Ok, a fair n00b here, especially on the Server side of Linux.

I've bonded 5 NICs for LACP link aggregation based on this guide: https://help.ubuntu.com/community/UbuntuBonding

Everything looks OK (except one of the ports on the switch is showing a 100MB link on one of the nics...

This is a curious case where all the devices at hand will link with one another, except for two that just won't detect one another. One device is a single board computer (SBC) with a gigabit nic, the other is a fancy managed gigabit switch.

If I patch the computer into any other switch (have two others models on hand in the lab), computer and switch link up fine.

CISCO : vtp server and client 1 year 30 weeks ago

I was doing some cisco exercises on configuring a vtp server and client, something I can't figure out is :

I setup a vtp server, added my VLAN's I then took another switch that was attached to this vtp server and set it to client Now my VTP client didn't get the vlans configured on the vtp server, however when I added another vlan on my server, suddenly they were all there

Is there a way to

I am looking for a gigabit switch that has 12 or 24 ports, and at least 2 10GB uplink ports (preferably SFP+).

Can someone recommend me any models? I am having a hard time trying to find out.

Given n (e.g. 200) clients in a /24 subnet and the following network structure:

client 1 \ . \ . switch -- firewall . / client n /

(in words: all clients connected to one switch and the switch connected to the firewall)

Now by default, e.g. client 1 and client n can communicate directly using the switch, without any packets ever arriving the firewall.

I am using SSH to forward a port on a remote machine (Client) to another machine (Server) using (~/.ssh/config)

Host Client:

Hostname {ip} ... RemoteForward localhost:{port} localhost:{port}

The problem is that even when there is not one listening on the Server, the client can connect successfully to localhost:port.

Network discovery in Java 2 years 44 weeks ago

Hi,

I'm trying to make a client/server Java App. Both client and server will be running on the same wi-fi network. Server will be running on a specific port that client is aware of.
