those have actually made a small difference, but not enough for uploading even an image over http. I guess that I can keep increasing those values till I'm not satisfied, but as I'm not sure on what I am dealing with, can anyone tell me if there's a rule of thumb? My machine is a laptop with a dual core processor and 2GB ram.
I need a shared buffer between user and kernel space. I read that one way is to allocated buffer in kernel and then call mmap from the user space. I searched for an example but couldn't find something useful. If you know, could you please send me any links or sample code that does this..

On a Fedora 11 machine, I configured ppp0 on eth0 and ppp1 on eth1, each one is connected to a modem, I also defined ppp0 as the default gateway.. Should I do anything else to load balance the 2 connections or will ppp1 take some of the load by default? Should I add any other routing rules? If yes then please tell me what should I add, keeping in mind that for each pppoe connection both the pppoe address and the remote address are not static so I actually needed some scripting to change the default gateway each time the remote pppoe address changes.

P.S.: I have another F12 system, on a second HDD, that I haven't updated since two weeks ago and I can connect to the internet with it. So this seems like a package correlation problem. I think it might affect more users than just me, especially those who only have F12 installed on their computers.
If this affects more than just me, I think the guise at Fedora should offer a script or a rpm to be used offline to, whether downgrade the "ppp" package, or to update the "/usr/lib/pppd/2.4.4/nm-pppd-plugin.so" plugin.
i can't get a pppoe conection working over a wireless network,in windows I have to connect to the router first, and then put in my user and password to get connected, but i don't know how to do this on fedora, i get connected to the router through network manager, and ping is ok, but when i try to make a new xDSL connection i don't know how to make it work through the wireless network that is established and working with my router.

Recently my ISP switched to PPPoEand since then my internet connection has been giving me problems. While browsing, some websites load fine, some websites load fine after I refresh once or twice, some load really slowly and the formatting tends to be messed up and some websites won't load at all (they stop at waiting for website...). Ping for all of these sites is however fine. Also uploading and downloading either from sites like rapidshare or using torrents is also fine. The same ISP also provides a second similar connection which is connected through a wireless router to two computers (one via a wired connection and one through wireless) both running Win 7 and everything works fine over there.
Things I've tried.
I tried using the router changing it's setting to my connection and connecting through that but the problem remains. After googling I thought it might be an MTU issue so tried this:
ping -M do -c 3 -s 1464 www.myce.com and got
PING myce.com (212.204.237.148) 1464(1492) bytes of data.

rtt min/avg/max/mdev = 129.261/129.683/130.044/0.436 ms
This works for various websites whether they load or not. My MTU is set at 1492 but I've tried various lower numbers all the way down to 1300 but no luck. I tried disabling ipv6 in Firefox but no change.
My network is windows pppoe. How can I configure it for Fedora 11? Is there any graphical configuration tool available for that? Also, ubuntu 9.04 logs into pppoe network after restarting as I've made some changes in /etc/network/interfaces. Is there any option available for Fedora 11 to automatically log in to pppoe network after restarting?
View 4 Replies View RelatedI am trying to send data via UDP using sendmsg on the sending side, and recvfrom() on the receiving end.The setup for my data is to have an iovec that has a packet hdr, followed by an iovec that has a payload, then to have subsequent sets of these two types of iovecs. On the receive end, I have a while true loop that does a recvfrom() receiving a size of 1 hdr/payload combination.When I do send out a message that has a total of just 4 iovecs (hdr/payload/hdr/payload) and I use recvfrom on the remote end with a receive size of a hdr/payload set,only the first hdr/payload of the sendmsg is received.I was under the impression that using this while true loop would allow me to receive multiple sets of this hdr/payload combination that is sent out by sendmsg().

Confirm that your Ethernet card is detected.
Enter your username (provided by your ISP).
Enter your password (provided by your ISP).

I am a newbie to Linux just installed Ubuntu 9.10 using WUBI. I am not able to connect to Internet using PPPoe. I went thru some of the threads and tried PPPoeconf and it works. So how to configure Network Manager so that it works.

in windows xp i use to untick use default gateway to make them work simultaneuosly but there is no option like that in ubuntu..!!
I got a new ISP, and it uses PPPoE. Let's say it's over eth1. After I connect there is a ppp0 -or similar interface. My question is what kind of firewall policy should I use on eth1? (block all, allow ppoe passthrough only or should I just do nothing?)

My adsl modem is in bridge mode . I can connect to internet via pppoe . pppoeconf recognise the pppoe in eth0 and setup a connection and i can use it .. Now , the Problem :
How can I setup a pppoe connection using pppoeconf so that it uses wireless ? I set the wireless mode to bridge in modem settings . But , after that , the access point stopped appearing in "aps in range" in network manager and i can't connect to it . pppoeconf also doesn't recognise wlan0 as a valid pppoe link . but dat is normal since i don't think it can check if wlan0 is pppoe without wlan0 being connected to the modem's wireless network .
SO , HOW CAN I CONNECT TO INTERNET WITH MODEM IN BRIDGE MODE AND CONNECTING VIA THE WIRELESS INTERFACE OF THE MODEM ??
sidenote : hey , is pppoe over wireless even possible ? coz the datalink layer of wlan is not ethernet rite ?
I have an internet connection with dial up created with pppconfig that I use Code: #pon connection_name to connect to internet in my ubuntu 10.10 platform and it creates me a connection over ppp0. I want to use a PPTP vpn, so I used this command
[Code].....
I have a machine with two network cards running linux mint 8 XFCE (which is compatable with Ubuntu Intrepid Ibex). eth0 gos out onto the network propper, has a static IP address of 10.10.10.10 and serves DHCP requests for the 10.10.10.x subnet.
eth1 is pluged into a PPPoE concentrator, and has a static address of 192.168.0.1 (I would have left it alone but pppoeconf wouldn't work unless it had an address).
ppp0 is the piont to piont over ethernet conection that is corectly created when I run pon. I have both guard dog and guide dog installed but they are both disabled.
Now, the weird part: I can ping the IP number of the machine at the other end of the pppoe conection (when it changes I can still ping the new number), the local IPs (10.10.10.x), but *nothing* else not even the DNS servers passed to the machine during ppp conection which are in the same sub net as the machine I can ping.
When I try to ping or trace the route I get an error message like: reply from 10.10.10.10: desination unreachable There is nothing wrong with the network at the other end, as I can make an Identical PPPoE connection from other machines on the network if the the concentrator is pluged into the hub (a rather unsafe place for it to be) and it all just falls into place.
What seems to be happening is that the machine is treating eth0 rather than ppp0 as the internet gateway, and passing the packets round in circles.
where packets are stored when they're received. After some googling, I think perhaps libpcap with mmap would be the solution. Does libpcap 1.0 and above support mmap?From my understanding, mmap would allow me to directly access the buffer without having to explicitly copy the packet to another buffer for me to do processing. I would also appreciate it if someone can let me know where I can find examples of such applications, as many examples of mmap I've found involves mapping a buffer for file operations, rather than integrating it with pcap functions like pcap_loop, pcap_next_ex etc.

When i boot to Ubuntu 9.10 i dont have internet...but if i restart the PC and enter in Windows 7 there is internet,and is the same connection,the same adresess. How can i make the connection in Ubuntu 9.10 with the same adress,i mean like is in Windows 7?
I just got lost. I have set up a server with two nics. eth0 for the lan and eth1 for the Internet. I have dhcp running on the server. I am using adsl and have run pppoeconf to set up my connection. I have turned off dhcp and nat on the router so the device works as a modem using bridge mode.The problem I have is that the server keeps hanging when loading pppoe or at least when pppoe has completed getting the public DNS addresses.What happens is that the Internet connection can be opened from the /network/interfaces file. This seems to work but it does not return control to the server - the process runs, the DNS addresses obtained but the rest of the processes following at start up never load (i.e. power on the server and the processes that load then).
So I thought that this must be in the wrong place. I commented out the items in the interface file and added a couple of entries to end of rc.local, my logic being that this will load after everything has finished. Nearly right but not. What happens is that all processes run and then the pppoe program runs and the DNS addresses obtained (seen from a screen connected to the server). But the system then stops. What should happen is that it continues to load and at the end return the login prompt.From a client I can see that dhcp has loaded since a private IP has been allocated but I cannot login from that client since the server has not finished loading.I am not sure what I have not done here since reading round I can see that what I have followed is the same as everyone else but I get a different result.

I contacted my isp but in Our country (Bangladesh) a very few people use Linux or Ubuntu so they cant help me out. i searched many forums,, googled everywhere but cant make it working. i tried some command like "sudo pppoeconfig" but still dont understand. I know there are many people who know how to do this. My Pc configuration:
Processor: Intel Core2duo E8400 3.00GHz
Motherboard: Intel DG41TY
Ram: Transend 2GB 800 buss
Hdd: Samsung sata 400gb
Lan: Realtek PCie GBe family (built-in)
Ubuntu 9.10
I have Fedora 13 also. It looks almost similar to ubuntu at network connection.. is the settings will be the same.
I use pppoe connection over wireless network, for long time I've used console, so I didn't had any problem with it, BUT - after installing gnome, I can't connect to the wireless ISP. On my network manager I see my wireless network, I can connected to it, but when I do it, I don't see DSL connection on my menu, If I only connect cable to it, DSL connection is showing again. What should I do to see the DSL connection when only wireless is connected ?
