I was wondering how much resources are necessary to run OpenVPN on a router or router computer at speeds of 50 Mbit/s. (I've Googled this and have found the results to be unclear)

View 2 Replies View RelatedI'm having a strange problem with my network connection/DNS. I turn computer the on and it recognizes and connects to wireless or wired but I can't access any Internet resources or my router. If I ping the default gateway, I get no response and I get DNS errors from any network services that run at start up. If I stop and start the network daemon then it all works fine until the next time I turn on my laptop. It does this for both wireless and wired connection.
I've tried to edit the network interface information in YaST but it says that configuration is handled by knetworkmanager and I have no idea where that information is accessed. I should point out that it all worked fine until I tried to connect to open WAP at my school and couldn't so I connected to the wired network. Next morning I had this problem when connecting to my home network. My questions are 1. What could be the cause of this error and 2. where does one configure the network interfaces when using knetworkmanager
Within the documentation of example OpenVPN setups there is a setup that shows an OpenVPN Server with two network interfaces. One interfaces is plugged into the public internet network and the second interface is plugged into the private network.
Normally I assume that it would be best to place the OpenVPN system inside the network behind the router and firewall and open only the ports needed on the router to allow access to the OpenVPN system. All other router ports would be closed. This is the first example they show. To see what I am talking about see page(s) 6-7 here -> [URL]
If one were to use the two interface public facing setup, when would that setup best be justified? I guess if you didn't want to open any ports on the router/firewall then this could be justified but then you have to lock down this public system individually instead of having it protected by the network firewall.
I'm getting a timeout error from NetworkManager when attempting to connect to my router/firewall.

I have bought two Asus NX1101 gigabit cards for my kubuntu box and ubuntu server box. The cards are automatically detected as eth1. However the speed is set to 100mbit instead of 1gbit.
ifconfig eth1 .....
capabilities: pm bus_master cap_list rom ethernet physical tp mii 10bt 10bt-fd 100bt 100bt-fd autonegotiation

I noticed that both lshw and ethtool claim that the card does not support 1000mbit. So changing the speed manually with ethtool doesn't work. In windows XP the card works as it should.
i have some problems with configuring openvpn tunnel connection to my openvpn server. I'm using static-key tcp connection. Network manager always said to me that connection could not be established. Also, when i try to run openvpn from terminal, i got some strange permissions problem:

i have installed openvpn and config it for a tunnel. my server.conf and client,conf is as follow:
server.conf
port 1194
proto udp
[code]...
I want to configure a VPN over the Internet.I installed the 'openvpn' package, generated the key file, transfered it by a secure way to the client, and setted up the configuration file.
So, in that configuration file I input the IP addresses of the tunneled interfaces. Both IPs are static in the tunnel.
Then, I've heard somewhere that I can assign a dynamic configuration IP for the client. I do this registering a range.
Well, when I tried to change static IP to dynamic IP (changing '192.168.0.2' to '192.168.0.0/24') in the configuration file, the OpenVPN didn't work.
Obviously I don't know what I'm doing, and I really, don't believe that simply changing the IP will make it work, but I tried.
I hope I explained my problem as well.
My configuration file:
# OpenVPN Server Configuration File
dev tun 0
ifconfig 192.168.0.1 192.168.0.2
cd /etc/openvpn
secret key_file
In client I execute the 'openvpn' without the '--daemon' parameter.Then I want that my client uses a IP in a range (192.168.0.0/24, for example), instead of a static IP (192.168.0.2).I also thought to use a DHCP server, but I'm not sure that will work.

View 9 Replies View RelatedI want to set up a Linux box as a wireless router to replace our existing Netgear WNR1000 router, as I believe the Netgear does not support the coming IPv6 protocol. Unfortunately, it is not flashable with OpenWRT or DD-WRT presently.
As we have Comcast, our cable modem acts as a dumb modem according to the customer support guy I talked to, and our router is the one that asks for the IP address from DHCP. Thus, when Comcast switches over to IPv6, I don't believe my existing router would work, correct?
My idea is to take a Linux box and put two NICs and a wireless adapter in it, using IPCop or Smoothwall to set up a router. I could then enable IPv6 support for when we have IPv6 with Comcast. Is that possible? Would there be a way to get BIND to hand out private IP addresses in the same subnet on the both the LAN NIC and the wireless card?
Does anyone know of any decent web guides that will help me set up a DNS service running on 127.0.0.1 that will automatically forward requests like [url] to httpd running on 127.0.0.1 yet forwards requests to [url]to a 'proper' DNS service?

I just wondering what is the difference between RES, SHR, and VIRT.
1) The VIRT always seems to be higher. Is this using the paging file system. (virtual memory on the harddisk, the swap memory)
2) Is the RES memory the actual physical RAM memory?
3) Is shared memory sharing memory with other processes?
4) Just a final question. As I am running on a HP Mini 210, memory and CPU is a resource I don't have a abundence of. So if was to compare for example 2 difference browsers i.e. firefox and midora. What should I brench mark between to 2 to find what one uses less resources?
I got a fairly powerful media system standing in the living room. Most of the time it is idle, maybe playing some music. At the same time I got a pc in my office that is less resourceful. Sometimes I'll run programs through ssh with the -XC command. This way a program will seemingly run on my office pc, while it is actually running on the media system. However:
- 1 Sound doesn't transfer to the office pc.
- 2 When using a program I need to constantly be aware where I save my files. Sometimes it is located on the remote computer, sometimes it isn't.
Is there an alternative way to use the resources on the media system? E.g. run a program that is stored on the office pc and process it on the media system?
Both systems run Ubuntu (office 10.04 - media system 10.10).
I just recently upgraded to 10.04 (LTS), and I have been using stardict app for a long time with nothing but success on each of my laptops anc omputers I have had over the past 5 or so years. However, now on one laptop after starting the stardict app, using panel the applet I create on my xfce4-panel (as per normal), and looking up a word (highlight and press shift key which i use for quick word search using stardict), the app begins using 100% cpu resources and I am forced to kill the process.
The problem is intermittent, meaning it only occurs half of the time I am using startdict, while the other half of the time it operates normally. I have been trying to see if there is some sort of pattern, perhaps other apps running at the time the problem occurs, but I have not noticed anything that looks suspect, since I generally fire up stardict after boot in and have had it happen (the problem) without even any other apps open (just testing to try and find some sort of pattern to locate the potential issue).
I use a standard set of dictionary files for each of my comps, and currently have stardict operating fine on 2 other laptops, both running 10.04, with the same set-up (xubu, same apps, and settings pretty much) and no indications of this problem on either (other) laptop.
I installed ubuntu 10.10 a few days ago which ran very well on the live CD but after I upgraded to 11.04 Ubuntu uses just under 100% of my cpu after a few mins loged in and my ram usage increases by about 5MB per sec starting the second I log in. I am using Classic Gnome and it seems to do this wether I have metacity or compiz turned on. Does anyone know what is going on or know about a way to lower ether my cpu or ram usage

View 1 Replies View RelatedI have a desktop PC running Ubuntu 9.10 and Windows 7, and a Eee PC 701 laptop running EasyPeasy Ubuntu 9.04. I'd like to connect the desktop to the laptop with a wired connection (eth0), then the laptop to my ADSL router using wireless (ath0).
I have a crossover ethernet cable (I bought on ebay). I have set up my laptop with a static IP address on my LAN and it uses OpenDNS.
I have added this to /etc/sysctl.conf on the laptop:
net.ipv4.ip_forward=1
Then I tried this on the laptop:
sudo iptables --table nat --append POSTROUTING --out-interface ath0 -j MASQUERADE
sudo iptables --append FORWARD --in-interface eth0 -j ACCEPT
This is a variation on what I found on other sites describing how to set up a router. I don't understand iptables very well, but I gather that the above two lines should set up forwarding so that traffic from my router to the laptop will be forwarded to the desktop, and vice versa.
But this doesn't work. The connection doesn't even establish between the laptop and the desktop.
I'm having trouble getting my network set up the way that I want it/had it. You see, when I first set up my network, I just had my cable modem going directly to my standard wired router (A D-Link DI-604), which had DHCP,and was connected to all of the computers on my network. I had one switch hooked up to one of the ports of the router, but this was a regular switch, and it would not try to assign IP addresses, it would just pass through the DHCP info as I wanted.
Now however, my network setup has changed. My room mate and I both got laptops, and we decided that we wanted to have wireless access so we didn't have to constantly plug in to the router.
Now my network is set up like this: The modem is hooked up to the router(DI-604), which is hooked up on the LAN side to our computers, our switch (which is hooked up to 3 more computers), and to a wireless router card (A Gigabyte GN-BC01).
The wireless router card has two jacks for ethernet. One for WAN, and one for LAN. The LAN side we have plugged only into the computer in which the card is installed.
Now the problem is this: The wireless router card comes with DHCP by default, and it's assigning addresses to the laptops and to the computer hat it's in, and worse, the IP addresses are on a different subnet than that of the main dlink router. The Main (dlink) router assigns addresses from 192.168.0.1 (itself) to 192.168.0.254, while the wireless router card assigns addresses from 192.168.1.1 to 192.168.1.254 (itself).
Because of this, I cannot access services on the wireless network from my wired network or vice versa. The first thing I tried was setting the card to assign addresses from 192.168.0.12 to 192.168.0.253, however it just said "internal error" when I tried to do this. I decided that this may be because it sees that it was being assigned an address on it's WAN side on the same subnet. So the next thing I tried was disabling DHCP and setting the "LAN IP Address" to 192.168.0.12, hoping that the DHCP would just go through the card, like a switch. I would have set the LAN IP address to be assigned by DHCP, but this was not an option, so I decided that'd be the best thing to set it to.
Once again however, setting the LAN ip address to an address on the same subnet as that of the IP assigned to it's WAN side caused it to report an "internal error". I verified that this was the issue by setting the LAN address to several other private IP addresses to test (I.E. 10.0.0.1, 192.168.3.1, 192.168.5.12).
My question then really is: How do I set up both routers so that I can access services and computers from each network from the other network. Should I set them with different subnets and set the gateway on the wireless network to the main router? To the wireless router card? Should I put them on the same subnet? Will it know how to communicate?
