Can I bind 2 interent connections or more on same fedora server to create bigger one with double bandwidth ,or it needs a specific router to be able to do this.
View 1 RepliesI have a question, regarding the use of two internet connection on the same server. So, the thing is like this: The server will have 3 network adapters: connected to a DSL modem (on this adapter I have one of the internet connections, a PPPoE connection. It's only purpose is to share the internet connection to all LAN users using SNAT.
eth1 ----> the other internet connection, a much more expensive one actually, used for hosting a website, a domain name server, and a qmail server. eth2 ----> LAN connection So what I want is to make eth1 the "default gateway" (for outgoing mail, DNS requests, etc) and, as I said, use the ppp0 connection on eth0 only for internet sharing in LAN.
My question is (since I'l configure this server in about one week), does anybody have any suggestions regarding how could I accomplish this? I mean, I'm affraid that ppp0 will also try to use the default gateway from the other internet connection and vice-versa. Now, I know I can use the ip route/ip rule commands, but for many reasons I'd like to keep it simple and not use them.

View 4 Replies View RelatedI have two internet connections. One is wired ADSL Broadband & another is USB EVDO modem. I can use only one source at a time. That means the traffic will pass through either ADSL or EVDO. Other connection just sits idle. I want to use both the connections together so that I will have increased bandwidth. Is there a way to do that?
My computer has one NIC card. Both ADSL & EVDO use dynamic IPs.
I recently installed Fedora 15 now, and during installation I set the internet connection manually, then did update and after reboot, the internet connection settings have been removed. Now I can not set because the network connection to the Internet Connection is inactive. I mention that before the update was functional internet connection.

View 2 Replies View RelatedI've got a Ubuntu Server Linux router that I've got 2 internet connections hooked to. One of them is DSL and the other is cable.
What I'd like to do is have everything go through the DSL connection EXCEPT for one desktop, I'd like that system to go through cable for everything.
Here's a diagram of how I've got things set up.

I don't have any more expansion slots on the mainboard of my server for another NIC, also I do a lot of file transferring between a laptop and the desktop I want on the cable connection so I don't want that slowing down the rest of my network.
I've got both providers set up in the providers file and I've got everything going through the DSL connection right now. So far everything I've tried has stopped the desktop from connecting out at all.
I have the latest Ubuntu (9.10) desktop. My 2 cards are:

I am a user of Ubuntu 10.04 and I use Firestarter because it lets me know which IPs I am connected to, which ports are used, and which applications are using those ports. The problem is that I can't use Firestarter with my non-sudo account (well, I know that I can change my system settings to do that, but I'd rahther not do it).
So the question is: Is there any application that lets the user monitor the internet connection?

The trouble is that once I connect with my windows machine to the server, I am unable to bridge through to the www. I have combed through so many settings and tutorials, and I am confused as to how to set up the interfaces configuration file. Here's a sample of my routing table:
Code:

I have seen several threads lately about slow internet connections here and elsewhere, but I haven't seen anyone post a reply about blacklisting ipv6 so I am curious as to why?Is ipv6 enabled only on certain distro's or is there some other reason that it's not mentioned?
<If anyone wants to try it, to see if it would work for them>
On Slackware 12.2 and Salix 13.0 just add "blacklist ipv6" to the /etc/modprobe.d/blacklist file. I'm not sure about non-slackware based distro's. Unfortunately, I don't know any way of doing it without rebooting.
I'm running ubuntu lucid and i was thinking in purchasing one or more extra wifi cards to try to configure my computer to manage different conections at the same time, with different isp's. The thing is that I'm not quite sure if what i want to do is actually possible.
The easiest way that crossed my mind was to try to configure a / multiple virtual machines that are redirected threw proxies to ubuntu and try to configure that each proxie port goes threw a different internet gateaway. This way i might be able to divide threw different sessions of JDownloader, installed on each virtual machine, the things i want to download. The negative aspect of this idea is having multiple jdownloader sessions will make my laptop work to almost 100% for sure...
Another thought i have was to make JDownloader manage its downloads in only one session redirecting them to my internet conections; the negative thing is that i think i will have to try to modify its source and learn java...
And well my last possible configuration i had in mind was to try to make ubuntu directly add up all my internet conections manage as if it was one. the negative thing here is that i might not be able to get multiple downloads from some sites
Well, all this where just thoughts, im struggling whether to buy another card or not to try to setup any of this configurations but im not really sure if any of them are actually possible. Is there an easy way to manage this?
I just want to take the most out of my internet conections... if i'm at college i have to options that are quite slow, adding them up with two cards would be great, i might also be able to add a third and a fourth conection. Also if i'm on a coffe and i need some bandwith i could try to make it go with an open network arround, etc.
My linux box has 3 network adapter. eth0 connects with ISP, eth1 is for staff network, eth2 is for public user. I want to limit the usage of internet bandwidth. for example, the traffic going through eth0, 75% is for staff network, 25% is for public user.In addition, I setup shorewall on it for port forwarding and filtering, but I felt the traffic shaping of shorewall is complex. I don't need the specific TOS, but only the percentage. could you give me some suggestion?Which software or package I should use to achieve this goal?
View 3 Replies View RelatedWhen setting up my server I noticed that I could control the amount of connections; the maximum seems to be 256.

View 4 Replies View RelatedMy problem is that I would like to load balance or aggregate 2 separate Internet connections on my laptop. Currently a hard line ISP is not available so I'm using an Sierra Wireless 885 USB air card. Thing is the card is quite slow. I also can tether an iPhone to the laptop. The ideal solution would be to have both connections being utilized to help speed up the overall experience, even if it is only a modest gain in speed.
as I do not know much about iptables and basic TCP/IP routing, I'm finding it difficult to implement those solutions. If someone can point me in the right direction ( a slightly dumb down how:to? or better explained? )

Each time my machine reboots, it takes about 2 minutes for an attempt of the YP server to bind (then it fails).
Code:
jim@LinuxBox:~$ /etc/init.d/nis restart

The previous is a YP server command while running. What happens at boot time is similar. I think I need NIS for my work. This looks like an old common problem (maybe on AMD64 - Ubuntu; which I have). The following link has a good description of NIS and this particular problem. It is a complex problem that I am spending some time working on. It looks like my problem may be that an NIS master has not been created. [URL]. I am trying to share files and run remote desktop with XP machines on a local network. The lack of NIS server may be contributing to my difficulties.
I'm trying to execute X server (automatically), which will not bind to 0.0.0.0 (port 6000) - meaning X server will not listen on generic interface. If it's possible, I'd prefer X server not to listen at all (and communicate through other IPC if needed), is there a way to make it not listening at all? -nolisten flag or something like that? (and do it automatically, every reboot). Also, Is there a way to make X server bind to 127.0.0.1(localhost) instead of 0.0.0.0(generic interface)? It should be in one of the configuration files or the start-up command to run X.

'm running on Ubuntu and I've succesfully setup apache alongside with a working php & mysql configuration - other computers connected to the LAN can access it by typing in my ip: 192.168.0.9however I would like my webserver to be accessible by all internet users...I've got my ports.conf file in the apache setup to listen on ports 80 and 8080 this is my ports.conf:PHP Code:

I have a bunch of Ubuntu boxes on one subnet, 192.168.1.0. I have a Windows 7 box on another subnet, 192.168.2.0. I am able to ping and SSH to all servers on the .1 subnet except for one server, which I will call PITA. I will attempt to SSH to PITA, and it won't respond, nor does it respond to pings. I will the SSH to PITA from another of the test servers, successfully connect, and then when I SSH from my Windows 7 machine I can connect successfully. If I first connect via console to PITA and send some pings out (to anywhere, like 4.2.2.2), I can also connect from my Windows 7 machine. I've never seen anything like this.
One of the weird things is that I used PITA to create an image that I then used to create many of the other test servers, and they work fine, so I'm not sure what the problem is. I've checked /var/log/messages and syslog and there's nothing in them that indicates a problem. I've rebooted this server, restarted SSH, changed the IP in case it was conflicting with something else, forced an ARP update in case it was cached (since I had bonded the interfaces), cleared the ARP cache on my own machine, verified Network Manager is not installed...and I still have this issue.
Here are some network-related config:

I've recently started using the "screen" multiplexer and it is really handy for some cluster work I've been doing. But if I am in emacs and I press C-A to go to the beginning of the line and the C-N to go to the next line, I get shunted to the next "screen" window. I imagine there are other conflicts as well. I did some googling, but all the suggestions showed how to adjust emacs key-binding to accommodate screen. But I don't want to adjust emacs key-bindings because that is the whole reason I like emacs. I think custom "screen" key-bindings go in .screenrc. Does any emacs fans out there who have run into this problem have any .screenrc code they would be willing to share with me that worked well for them?

I just installed Fedora 14 in a hard disk of my PC. I installed MySQL also. I dontt know if this is the correct site for my question, but nobody MySQL related, have an answer yet. For MySQL accepting remote connections, my.cnf file must be edited (bind-address line or skip-networking line in that file). Well, that file in my Fedora-MySQL installation does not have such lines, so i assume, TCP/IP connections are allowed in MySQL. When i try to connect to the MySQL server it refuses the connection with the error 2003, that in short, means no TCP/IP connections are allowed. I disabled the firewall and retried but with no success, enabled the firewall again, and nothing happen. Is Fedora not accepting TCP/IP connections?
