View 1 Replies View RelatedAt work I have been given the "opportunity" to provide admin support on a bunch of RHEL3, 4, and 5 servers. My latest problem is, as the subject hints at, adding persistent (or permanent) routes on a RHEL5 server. I've successfully done this with a couple of RHEL4 servers by adding the relevant information to the /etc/sysconfig/network-scripts/route-eth0 file like this:
GATEWAY0=xx.56.200.129
NETMASK0=255.255.255.128
ADDRESS0=xx.56.200.250
On the RHEL5 servers I do not see a route-ethX file. Do I just add the file and the route info? Or has this functionality been moved to another location?

I am realtively new to BGP. I use BGP in my network to advertise my /20 subnet. What i would like to know is what is the point of accepting routes from your neighbouring AS(ISP)?My ISP has given me a default gateway, and no matter what I want to reach on the internet I have to go through that default gateway, so why populate the routing table with soo many routes?also, as i understand it, there are 3 kinds of routes that you can accept, those are full routes, directly connected routes and default routes. What is the diffrence between them and again how do they affect routing since my network only has the one default gateway?
View 2 Replies View RelatedI currently managed it to get a pptp-connect to my home network. now I have another little problem. NetworkManager always routes the whole network traffic over my home network if i am connected to the home network.If i set the "Use this connection only for resources on its network" I have do manually say:
Code:
route add -net 192.168.1.0 netmask 255.255.255.0 dev ppp0
After that only the correct traffic runs over the vpn. Now my question is it possible to setup the route via the networkmanager gui?
First I will give some background. We have a currently working network that the Previous network Admin assigned an internal IP scheme of 200.1.1.0/24. I have no idea why he would have done such a thing, but it is my job to fix it (and keep our systems up and running). We have a Fedora 10 box on the 200 network that is acting as a router and a firewall (shorewall to be exact).
I added another NIC card (thank you again to all the great people on this forum for helping me get that working) and it is eth2. Assigned it a 10.100.1.A/24 (This is just a variable for the real IP). The other end of the cable that I plugged into that NIC connects to a Cisco Layer 3 switch. I assigned the port that connects to the other end of the cable the IP address of 10.100.1.B/24
Ok, I added the static route of ˜ip route add 10.100.1.0/24 via 10.100.1.A dev eth2' I added loc2 (which is my eth2 adapter) to the /etc/shorewall/zones file. I set eth2 on loc2 in the /etc/shorewall/interfaces file. loc2 eth2 detect I set the lines in the /etc/shorewall/policies file loc loc2 ACCEPT info loc2 loc ACCEPT info I can ping the cisco switch from the linux server itself. From a PC on the original network I can ping the new NIC card in the linux server, but cannot ping the cisco switch, so I figure it has to be either the route or shorewall.

I am using the suggested openvpn routes. If I connect from Windows (actually the .ovpn file is taken directly from the working windows machine).. all is well, routes work fine all traffic is routed thru the VPN -- same way it's worked for over a yar. I assume that this is what is causing networkmanager to fail as well. those logs indicate that it has connected to the vpn, but is probably stopping when it gets to routes.
I've got a 10.04 machine with two ethernet interfaces. I have two separate outside internet connections. This machine is connected to both interfaces. But it DOES NOT route between them. It's just a host on both subnets. Again, no routing is to go through this host. I'd like to force traffic originating on each ethernet port out to that network's internet connection.
Here's the desired setup:
eth0 192.168.12.37/24 gw 192.168.12.1
eth1 192.168.1.37/24 gw 192.168.1.1
I'd like traffic on the 192.168.1.37 address to go out through the 192.168.1.1 gateway. I have a program bound to that address and need it's traffic to go out ONLY through the 192.168.1.1 gateway. Any other traffic on the machine should go out the 192.168.12.1 gateway.
The logic is: source IP is 192.168.1.37, dest IP is any then go out only through 192.168.1.1 source IP is 192.168.12.37, dest IP is any then go out through 192.168.12.1 first or 192.168.1.1 next. The point is source on the .1.37 address must always go out the .1.1 gateway and NEVER through .12.1. Whereas traffic on the .12.37 address should try going out the .12.1 gateway first but can go out the .1.1 gateway if the .12.1 connection is down. I could live with this failover option. I could accept that traffic on the .12.37 address was likewise limited to its own gateway.
I just set up NIC bonding in Ubuntu 10.4, following these instructions, and I've got it working except for one problem: Every time I up or down a network device, or every time the system reboots, my routes go all to hell with eth0 and eth1 entries next to my bond0 entries. When the eth0 and eth1 entries show up, my connection is hosed and I have to go in via the maintenance IP to kill each route one at a time, leaving only bond0. Here's how I want my routes to look at all times:
Code:
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
10.87.9.0 0.0.0.0 255.255.255.0 U 0 0 0 bond0
0.0.0.0 10.87.9.1 0.0.0.0 UG 100 0 0 bond0
Here's my /etc/network/interfaces:
[Code]...
On a server with 4 network interfaces, sometimes not all 4 are plugged in. All 4 interfaces have the same IP address. Sometimes the machine cannot access the local LAN, but can access the internet via a router on the local LAN, after a reboot. What I find is that the routing table looks like this:
Code:
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
172.30.0.0 0.0.0.0 255.255.0.0 U 0 0 0 eth0
172.30.0.0 0.0.0.0 255.255.0.0 U 0 0 0 eth1
172.30.0.0 0.0.0.0 255.255.0.0 U 0 0 0 eth2
172.30.0.0 0.0.0.0 255.255.0.0 U 0 0 0 eth3

0.0.0.0 172.30.0.2 0.0.0.0 UG 3 0 0 eth2
0.0.0.0 172.30.0.2 0.0.0.0 UG 4 0 0 eth3
On the console I cannot reach any local host, but I can reach internet hosts. Pinging the gateway router 172.30.0.2 gets no answer. When I manually change it to this:
Code:
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
172.30.0.0 0.0.0.0 255.255.0.0 U 1 0 0 eth0
172.30.0.0 0.0.0.0 255.255.0.0 U 2 0 0 eth1
172.30.0.0 0.0.0.0 255.255.0.0 U 3 0 0 eth2
172.30.0.0 0.0.0.0 255.255.0.0 U 4 0 0 eth3
0.0.0.0 172.30.0.2 0.0.0.0 UG 1 0 0 eth0
0.0.0.0 172.30.0.2 0.0.0.0 UG 2 0 0 eth1
0.0.0.0 172.30.0.2 0.0.0.0 UG 3 0 0 eth2
0.0.0.0 172.30.0.2 0.0.0.0 UG 4 0 0 eth3
Then all is well (can ping local hosts including the gateway router). I do have metric specified in the /etc/network/interfaces file like this:
Code:
auto lo
iface lo inet loopback
auto eth0
iface eth0 inet static
address 172.30.16.8
netmask 255.255.0.0
network 172.30.0.0
broadcast 172.30.255.255
metric 1
auto eth1
iface eth1 inet static
address 172.30.16.8
netmask 255.255.0.0
network 172.30.0.0
broadcast 172.30.255.255
metric 2
auto eth2
iface eth2 inet static
address 172.30.16.8
netmask 255.255.0.0
network 172.30.0.0
broadcast 172.30.255.255
metric 3
auto eth3
iface eth3 inet static
address 172.30.16.8
netmask 255.255.0.0
network 172.30.0.0
broadcast 172.30.255.255
metric 4
Apparently that metric setting applies only to the gateway route, not the LAN route. Is there a way to specify the LAN route metric, too?

Andreas Vinther, 1977, from Denmark
I'm trying to establish a connection between two seperate ADSL LANs (coming into the house, but from separate ISPs) to a situation where all hosts on either LAN will be able to reach any host on eiher LAN WITHOUT having to use an excess of plastic routers around the house, and please no Wireless bridges. WiFi will only be available as Access Points.
I've heard that Debian does this kind of static routintg / RIP stuff quite well. And I just happen to have one lined up in the right place, that haven't got at snowballs chance in hell of running WINXP or above. But it kills at textbased datamanipulation/forwarding/rerouting/dropping/scanning ... so I'vew made up my mind. That is what I want to do... Now how do io get around doing stuff like that.
The Debian box is connected to both networks: Hostname: AsusAnd
(192.168.1.0/24 - TDC network)
and to
(192.168.15.0/24 - Profiber network)
Needless to say, but both netmasks are 255.25.255.0 hence the /24 The respective router's LAN addresses are 192.168.1.1 and 192.168.15.1 My Debian are locked to the following IP's (reserved DHCP):
eth0:192.158.1.56 via DHCP from 192.168.1.1
eth1:192.168.15.177 via DHCP from 192.168.15.1
So far so good - Now here we go ! This is not a scenario where i'd like to always want all network-packages to travel the shortest path, nor NESSESARILY use the other ISPs gateway if the first is down or slow, although that'll be super nice.
I suspect that'll involve router-protocols like RIP. I'll be super pleased to get some guidelines there as well, as i suspect it'll be quite easy to implement once everything else is in place. Although RIP isn't our main goal, it probably comes as a close second. I think we all would like as stable and fast a connection as possible.
I was actually so naive that i thought if i added two static routes to the two routers x.x.1.1 and x.x.15.1, that my problems would automatically be solved by my Debian box, and that it would automatically act as a gateway when the routers send their packages for the other net. As long as i was connected to both LANs at the same time.
Note: I haven't changed or tweaked the Debian kernel to do routing. this is a simple stable install from the net-inst.iso of Debian 5. I'd like to keep it that way unless there's no way around it.
my routers have static routes to each other (WITH PROPER CABLING), configured as follows:
(On router with LAN 192.168.1.1)
[static route] to 192.168.15.0 with nmask 255.255.255.0 going throuhg gateway 192.158.1.56 ( Taken from above info ) - metric around 2

I'm trying to setup routes for a gateway that resides on a different subnet. Our ISP leased us a block of IPs and told us to route through the current gateway, which is on a different subnet than our current block of addresses. To test, I've enabled one of the new addresses on one of the existing machines, which works. That machine has an address on the same subnet as the gateway, however.
The gateway address is 24.111.1.177 One of the new addresses I'm trying to use is 96.2.192.130, netmask= 255.255.255.240, broadcast= 96.2.192.143 Obviously, I can't just specify that gateway in /etc/network/interfaces without some routing, which is where the trouble I'm having is. The machine I'm trying to set this up on is part of 2 networks - one internal, on two different NICs.

I bought an RTL8187L USB wireless adapter, and have had trouble getting it to work. I have managed to get it to work via manually configuringtime, but lost that configuration, and now it is once again not workingThe root issue appears to be (if I'm understanding correctly what I'm seeing) that when I connect, routes don't get setup properly, so when network manager (or WICD, which I've also tried) get to the DHCP step, my wireless router can't be reached by dhclient.
This is on Ubuntu 9.10, and I'm using the updated driver from realtek.com, btw, though the in-kernel driver was exhibiting the same behavior.So, two questions:- Is anyone familiar with this problem, and is there a fix available?- I believe I can work around it by setting up routes manually (e.g. with a post-connect script in WICD), but after staring at the "route" manpage, I'm not 100% sure of the commands.

I'm running Ubuntu 11.04 on my desktop and the 70-persistent-net.rules file seems to be ignored. The ethernet interfaces are randomly shuffled around on boot (i have 4 interfaces). The original one was configured to have a static IP address (eth0). Is there anything that prevents the /etc/udev/rules.d/70-persistent-net.rules from being applied/used?
View 1 Replies View RelatedI am working on a Fedora 13 iso that will be used on some of the PC's at my work, the computers will have a varying amount of Ethernet ports, at least two onboard and up to 6 external. In order to ensure that the same physical port on the back of the computer is always used for the internet connection I have written a script to rearrange the contents of /etc/udev/rules.d/70-persistent-net.rules. The script ensures that the two Ethernet ports on the motherboard are listed as eth0 and eth1, without it they could end up as any port in the eth0-7 range.
The script works well however when its run I need to reboot the PC for the ifconfig to load the correct port as eth0/eth1. I have tried placing calls to my function through the rc.sysinit/rc.5d/rc.local and so on however nothing seems to work.Is there a way to make ifconfig check the mac/eth configuration files for changes (There appears to no longer be an ifprobe command which sounds like what I need). Alternatively is there somewhere I can place the script after udev has created the persistent-net.rules but before anything else loads the information. I have tried chkconfig --level 2345 network off and loading the service later but it still uses the wrong information, only a reboot seems to get it to work
As root, I can mount the /home directory from my desktop to my laptop which uses wireless. However, when I logout the mount disappears. That is, I mount the directory, check it is mounted, then I logout, log back in as root, the mount is now not there. How do I make the mount persistent, always there?
I want the mount to persist so that the two ordinary users on my small household network can access the same files whichever computer they use.
It appears that this may be because the wireless link disappears when I log out. Both machines are using Fedora 10. A persistent mount used to work using Febora 8, but maybe some settings I am not aware of have changed.
