Does anyone havea good tutorial on Fedora's network scripts, how to edit them, in what order they are called, etc. What I want to do seems simple, but something in the bootup keeps changing it. Right now, I have an image of Fedora Core 7 created in a server with 2 Ethernet cards. I need to specify static IP addresses for each card. Thats simple, and I did that. Now, heres the tricky part, I need to be able to clone this image and place it onto other exact duplicates of the hardware, and have all of the settings stay the same.
What happens here, is that eth0 and eth1 are stored somewhere as devices, and upon boot on a different machine, the Fedora will mount new network cards(different MAC addresses) as eth1 and eth2. It then mvoes my ifcfg-eth0/1 to a backup, and creates two brand new network setting's files, which initialize to DHCP. This creates an issue, becuase these machines do not have monitors nor keyboards attached, nor is their a DHCP server, so its a pain when I swap the machine out, to have to go in with a keyboard/mouse/monitor and reconfigure the network settings before I can connect to it over the LAN.
So does anyone have any advice on how to do this? No matter what i tried, booting the image in a new PC caused Fedora to create two new devices and create brand new network settigns for them, both initialized to DHCP. Hell, I wouldn't care if it created brand new devices, if it would initialize them to static IP addresses that I am expecting.
I have just installed Ubuntu for the first time, and I installed sucessfully World of Warcraft, but I'm noticing some networking issues where my whole network connection seems to pause for about 5-10 seconds at a time, which I finally realized when I played WoW. So i was curious where the settings are that I can change to possible eliminate that, or what others have done to increase their network throughput on their cards.
I'm running Unbuntu 9.10 64bit with the latest version of Wine from the Synaptic Package Manager. The router is a LinksysWRT54G3G-ST and my wireless network card I think is something made from MSI I don't see where to find out what drivers are installed on it I'm probably just looking in the wrong place or I'd give more information on the card.
I'm using Git to get my self an enourmous (2.5 gig) repository. Is there anyway I can PAUSE it?
OR is there anyway I can "half" download it, and keep what I have?
I have two interfaces, gprs0 and gprs1, both connected to the Internet from the same HW device, but through two different access points I just read another blog entry with a guy who had two network cards, using one as a back up - I guess this is a little similar, but should be much easier I am guessing - I am just lost Using ifconfig (IP address given by the network) and route to setup the connection,
ifconfig gprs0 10.20.30.40 up
route add default dev gprs0
ping 66.102.7.99 works fine
afterwards

There is data being transmitted and received to device again, I guess the kernel just doesn't know where the incoming data should go without the correct routing tables? Or what exactly is going on?The question I have is how do I configure the device to do the correct routing, using only the ifconfig and route commands? Maybe too trivial for you guys, but I am getting tired of goofing around not knowing what is up and down anymore

View 1 Replies View RelatedI am using Ubuntu 9.10. I just got a Linksys WRH54G wireless router. I want to protect my wireless connection by putting a password to it but when I enter the Router's default IP address (192.168.1.1) into my browser to open the 'Utility Welcome screen', the browser does not respond.
According to the Router's manual this is because PC' TCP-IP is not set to automatically obtain the IP address.
I recently bought a dell inspiron 14 n4010 and i've installed windows and Ubuntu 10.04 in it. The problem is that i'm not able to access internet in my ubuntu. I'm using asianet broadband connection and i'm able to get internet in my desktop when i connect the cable to the system. But when i did the same with ubuntu 10.04 in my laptop, i'm not able to get internet access. I'm able to access internet in windows though. But i hate using windows.

View 1 Replies View RelatedI have 2 pc's at home, neither v flashy but both more than capable of running this. Previously I had them both running XP SP2. One pc has 2 NICs in it and the second only one. So, PC1 (now running Ubuntu desktop 10.04) has the 2 NICs installed ...
1) A realtek NIC which is on 'eth1' and from which I receive internet connectivity from the router of this shared house. (2 other people connect their PCs to the internet via this router.)
2) A 3com NIC on 'eth0' which I have connected (using a crossover cable) to the Intel 'PRO100 VM' NIC on PC2.
Admittedly this took me some time to get half working. Currently I can connect to the internet through 'eth1' OR to PC2 via 'eth0' BUT NOT AT THE SAME TIME. However, If I disconnect one (by left clicking on 'disconnect' under the top of screen menu bar, then the other one will immediately work ... and visa versa.
I had this working when both PC's were running windows XP but now in trying to educate myself further I have installed Ubuntu on PC1 and am attempting the same thing. I refuse to accept that as alot of these thread responses state, that it 'can't be done'. Quite clearly it can be done since the physical connections and hardware are no different, its just about ensuring that the protocols are all correct and that I haven't done something stupid.
I am very keen to learn more about computer networks and equally keen to educate myself in the ways of Linux, in fact I am studying to gain a network qualification as we speak but at this stage its still a little confusing. I have learned an awful lot about the fundamentals of networking but the 'hands on stuff' is where I really need to test myself.

View 7 Replies View RelatedI have a system with one (sometimes two) ethernet ports, that works happily in an old Fedora 5 build. But I can't get it to work on a new Centos 5.4 build. Original system: One dedicated ethernet port on card always connected to the systems dedicated equipment and no external access (the system is the DHCP master for that network). An optional second USB dongle that is a second ethernet port, used for debugging and development. (This is a DHCP client with full conectivity. In /etc/sysconfig/network-scripts I have ifcfg-eth0, ifcfg-eth1 and a route-eth0. Neither of the ifcfg files needs an explicit HWADDR, which means the same ones work for all boxes. And when one needs to be connected to the network all is fine.
The system is being moved to Centos 5.4, most is working with minimal change, but I am having problems with the ethernet ports. If it only has the on board ethernet connected, all is fine. If you have the USB dongle connected things go wrong: This system brings up the USB ethernet first, and tries to assign it to eth0 (which fails), and then brings up the on board ethernet as eth1 (which also fails). I have tried forcing the behaviour of the network by setting the HWADDR(s), but this does not result in the on board coming up as eth0, it comes up as __tmpxxxx as follows:
ifconfig -a
__tmp226406138 Link encap:Ethernet HWaddr 00:80:66:07:A8:63
BROADCAST MULTICAST MTU:1500 Metric:1
RX packets:0 errors:0 dropped:0 overruns:0 frame:0
TX packets:0 errors:0 dropped:0 overruns:0 carrier:0

Currently the only solution is to unplug the USB dongle through restart and plug in afterwards, and this wont work when the unit is remote and in the field.

View 1 Replies View RelatedIs there a way to pause installations/updates? If there is not, would it be possible to implement that?It seems these days that installations through synaptic seem to take ages to download files. While downloading the files, ubuntu will not let you run any other package manager. So if I am updating my system or installing several programs through synaptic, I am unable to install anything else. For example a deb file ive downloaded, or i would like to install a single program while all these other files download.
I can understand not being able to install multiple things at once, but why is it not possible to install things while it downloads the files? Sometimes it days several hours/days to download the files.

View 1 Replies View RelatedAs you already know there's a command in the "BATCH" language named pause which causes the program to get any random character and then continues the scripts (which is mostly used to keepscript running and preventing it to do its work and close the command prompt).Something like the "getch".Is there anything similar to this at bash?IMPORTANT NOTE: I don't want my script to stay opened, I want it to get a character (without hitting enter) and continue executing the rest of the script so please don't reply "Tick the keep the terminal opened option" or "Use read"

i have to work at my home in my office. For that purpose i use a laptop with Windows (i really don't know why) XP. As i moved to Fedora 10 i want to make the same thing in Fedora.. Really don't know how. i have a cable connection and a router at my home ( i posted another message mentioning the fact of my wireless connection).
At my office i have a router , a firewall and 2 servers that i am allowed to use and i have to work on them (one is an AS/400 from IBM).
I've tried both the firewall interface that comes with Fedora and Firestarter, neither can configure as I want. So I think I'm going to have to do it by hand. In this laptop I have one 10/100 Nic and one wifi connection, at times either of them can be connected to the network. How can I configure IPtables so that any traffic is allowed out, nothing is allowed in (other than std stateful firewall replies), no icmp and that the fw logs any attempts to connect to the laptop?
