I have a problem with the activation of routing under fedora. The problem lies exactly in the file ip_forward who I didn't not change the value to 1. When I use the command echo 1> / proc/sys/net/ipv4/ip_forward. They appears not granted permission. Knowing that I use the root account.

View 1 Replies View RelatedIN LAN default GW box I have a routing rule of 172.17.1.0 192.168.180.100 255.255.255.0 UG 0 0 0 eth3 that sends packets matching 172.17.1.0/24 to eth3 etc. When I ping 172.17.1.50 - it goes correctly when ping is issued in the same box (LAN GW) - falls through to default rule when the ping is done in LAN's boxes i.e. it goes to the LAN GW box and then to Internet incorrectly instead of going to eth3 and 192.168.180.100.
Is there any way of seeing why the packet matches or not the routing rules?

View 1 Replies View RelatedI have just installed Fedora 10 on an old laptop and was quite impressed with how smoothly it all went ... until it came to setting up networking!
I have battled for three days now and I'm almost there;
- installed updated firmware to the built in Broadcom 4306 wireless network adapter
- got NetworkManager to work with a static ip address by manually editing the ifcfg-wlan0 file
- managed to get the WPA security to work
The only problem I am left with is that there is no default route; if I set one up using: ip r a default via 10.1.1.1 dev wlan0
Then everything starts working.
If I try to add routes using the NetworkManager gui interface they dont get saved (no suprises there then! ).
I have tried creating a route-wlan0 file in /etc/sysconfig/network-scripts/ but this seems to be ignored by NetworkManager.
Since the NetworkManager GUI is almost useless, does anyone know if there are any other configuration files I can manually modify to get a default route set?
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.
View 4 Replies View RelatedI want to implement routing using fedora 14. The following is how I arrange my computers -
[PC1]<=======>[ROUTER]<=======>[PC2]
And the following are the configuration -
PC1 : (Tiny Core Linux)
eth0 192.168.2.2/24 (netmask 255.255.255.0)
ROUTER (FC14)
eth0 192.168.2.1/24 (netmask 255.255.255.0)
eth1 192.168.4.1/24 (netmask 255.255.255.0)
PC2 (Tiny Core Linux)
eth0 192.168.4.2/24 (netmask 255.255.255.0)
On the ROUTER I have set the ip_forward=1 and eth0.proxy_arp=1 and eth1.proxy_arp=1
then I run the following command :
route add -net 192.168.2.0/24 gw 192.168.2.1 dev eth0
route add -net 192.168.4.0/24 gw 192.168.4.1 dev eth1
On PC1 I executed the following :
route add -net 192.168.4.0/24 gw 192.168.2.1 dev eth0
and for PC2 I run the following
route add -net 192.168.2.0/24 gw 192.168.4.1 dev eth0
After doing those things, I can't ping between PC1 and PC2... but both can ping the router...
I'm currently reading through the Linux Advanced Routing and Traffic Control HOWTO from lartc.org, and I'm wondering whether anyone knows of a file where I could keep qos rules persistent across a reboot, similar to /etc/sysconfig/iptables for netfilter. Should I just write my own script, or does something already exist?
By the way, iproute-2.6.29-4.fc12.i686.
i have a Server, which has 2 nics installed. Each of those is connected to a router, which is connected to internet. On the server, i have apache, maillserver and im-server running. On the other hand, also squid, dansguardian and clam are running. so now: via eth0 i would like to have just the traffic, which is requested from outside (the big bad internet..) to my server (apache, mail, etc). via eth1 i would like to have all OUTGOING (also to the big bad internet) from the server, which is requested by a internal client. And of course all requests to my own server
both nics shall route their traffic to their own router. For better comprehension please consult the enclosed graph. Until now, i did not find a good solution, the default route is set to the traffic from eth0, if not, no external request will find back to a client do you have a idea how to handle this the easiest way?
I don't know what I'm trying to achieve falls into 'routing' or 'Bridging'???I have two network ports (with static IP ) and I would like to forward RX packets of one to the other.
I have done this in Windows by enabling a service called 'routing'.Is there something similar in Fedora 11? I am pretty sure there are a few thread explaining these but I am just not educated enough to find one that makes sense to me, so Please excuse me for starting a redundant thread and point me to it?
I am having trouble for routing port 80 from a Billion adsl modem to a guest server in VirtualBox. There are quite few different changes from my last setup so I kind of confuse which one is wrong.
I used to use have the setup belowusing modem Linksys WAG354G use static ip 192.168.1.100 for my machine use static ip 192.168.1.102 for my guest VirtualBox server guest OS is serving http listening on port 80 i use bridge from my host OS for VirtualBox set my modem to direct all traffic on port 80 to 192.168.1.102 host OS was Fedora 11
now I useusing modem Billion 7404VNPX use same static address and configuration host OS is Fedora 13
main issue is I cannot reach the guest OS if I navigate to my modem ip address. (e.g. http://192.168.1.1) if I change the modem to direct all traffic to my host OS ip address (192.168.1.100) it works nicely.
I have tried to disable and enable the firewall without any luck.
When installing, I was not prompted to enter root password, but I was prompted to enter root name, user name and user password. Now it seems Terminal opens with admin permissions for user. This is not good.

I've been experiencing a problem with Fedora in which when I enable Wireless in Fedora, Wireless networking does not work in windows. HOwever, when disabled, it works correctly. Windows claims it is "not able to find any networks to connect to"
EDIT: It seems that when wireless is disabled manually on fedora before shutdown, there are no problems in windows.
i know exactly what i need to do, im just not familiar enough with command line to do it properly.i have 7 computers.the first 4 are connected to a router via wireless at one end of the house. of the last 3 only 1 will be able to access the router via wireless, so it needs to share it's one wireless connection via ethernet. this computer i'm going to call 'server'server will have two IP'swlan0 192.168.1.6 this connects to the router that has internet access.eth0 i intend to have the following settingsip:192.168.0.1sub: 255.255.0eth0 will connect to a second router, where the cat5 cable goes from the server, into the internet port of the router where i will define the router's static IP:IP: 192.168.0.100sub: 255.255.255.0gateway 192.168.0.1i have then set the router IP for LAN handling as 192.168.27.1 and all ethernet connections will have a 192.168.27.x IP.
so i need to know how to, without a gui application, use the terminal to assign server eth0 a proper IP address, and tell the server to take the connection it has and share it through eth0 to supply internet for the last 2 computers via ethernet.i had it set up in this way with a windows machine being the one that had the wifi access, but i'd rather have it setup for the ubuntu server to do this task. security is imperative for these 3 remaining machines, so just getting 2 more wifi adapters for a connection to the initial router isn't an option.the 2 that connect to server do so through SSH and though server IS connected via wireless it only makes outward connections through
I run a small home network with a wireless network using Apple airport wireless router. I have two macs and one Linux box (Fedora 13). Everything worked until about a week ago. Now the two macs can communicate with each other, and one of the macs can communicate with the Linux box, but the other can't, which is a bummer because it is a print server.
Pinging from the mac to the linux box gives the error message:
ping: sendto permission denied
Ping from the Linux box to the mac just hangs:
[/home/pjs] # ping 10.0.1.5
PING 10.0.1.5 (10.0.1.5) 56(84) bytes of data.
Firewalls on both boxes have been disabled. The Mac was running Little Snitch, but it has been uninstalled.
I have looked for messages from /var/log/message using tail -f and there are none when I ping either way.
ifconfig and /etc hosts, hosts.allow and hosts.deny look normal.
I'm trying to set-up a diskless environment on my home network, based on a F12 server and one FC14 client and I have a problem that I think is related to NFS, but googling around I cannot find any solution.
Basicly the client boots correctly, gdm fires up showing the login window, but the system doesn't let me in, if I switch to console (CTRL+ALT+F2) I cannot login with both standard and super user getting a "permission denied" error.
I tryed to mount the exported fs on another computer and ls -l on the mounted dir shows both user and group set to nobody.
If i mount the exported dir on server side (i.e. mount -t nfs localhost:/...) permissions user and group shows correctly

I am new to Linux world. I want to configure wireless on my laptop to use ADSL.
View 9 Replies View RelatedMy setup is...I have a wireless access point using laptop as a gateway. The AP is also connected to a switch as is the laptop. So the laptop has two interfaces one wireless and one wired. A third device is using the AP to connect to a server on the internet. The AP sends the packets to my laptop where they are dropped. I've been looking for a solution to this problem without success. Basically is there a way for my laptop to forward all packets it sees from a certain IP address to whatever destination address they have?To clarify, my laptop is just the gateway of the AP and none of the packets are addressed to it at all, it just picks them up using a sniffer or similar tool.

View 4 Replies View RelatedI am having some trouble setting up routing on my Ubuntu 9.10 Server. I have the GUI installed with Webmin and OpenVPN Heres the setup :
1 NIC - WAN - eth0 - IP: 146.231.x.x SUBNET: 255.255.252.0
1 NIC - LAN - eth1 - IP: 192.168.1.1 SUBNET: 255.255.255.0
1 NIC - ADSL - eth2 - dynamic
What I need to do is the following.
All users are connected to the LAN.
All requests for IP range "146.231.x.x", and "domain.com" need to be routed from LAN (eth1) to WAN (eth0).
All other internet requests need to be routed to ADSL (eth2).
-> I have the masquerading in the linux firewall working for NAT, but all traffic goes to ADSL (eth2).
-> I am using OPEN-VPN over the ADSL also.
-> DHCP and DNS work fine.
I also need all ports opened with the route (from eth1 to eth0)
I have a Fedora Linux machine and a Windows XP machine and I want to enable TCP/IP connection between them using a cross-over cable. I have a type of middleware server running on the linux machine and I want to be able to run the client for the application on the windows machine and work that way. I have heard Samba as a solution but my understanding is SAMBA is mainly for file sharing.. and is not necessary for establishing TCP/IP connectivity. Is this a correct statement? How can I go about setting up TCP/IP connectivity between the two machines?
