similar to: IP address change management

Hi, All, So far, all the applications I have seen for Iptables are focusing on connecting a WAN with one IP address to a LAN and using NAT. My question is if the iptables support multiple IP address on WAN side? If so, how it works (you only have one NIC on WAN side)? Is static NAT (it might not be the right term, I mean a static and permanent connection between WAN IP address and LAN IP address)

Hello , I used Vmware 4.0 to setup a virtual linux network . I added a new virtual PC and therefore I need to add a NIC on old virtual PC . I setup the ip address of this NIC by using the command : ip addr add 192..../ 24 dev eth1 but when I restart the computer the ip address of this NIC was not saved . And the tc script I used was not save when I turn off my computer , too . Could

[i''m not clearly a network guru, but i''ve some knowledge... anyway i think i''ve arrived to my ``end point'''' here. Probably i''ve also done some big mistake, so please sorry me.] I''ve setup in a local branch of my office two servers, say radagast (10.27.1.2) and olorin (10.27.1.3). They share the same UPS and the same place, sitting at

Hello all, Does anyone know of a methodology to build a route based on the inbound and outbound interfaces as opposed to ip addresses? We are essentially trying to forward packets from one interface to another without looking at the ip address. Bridging (brctl, br2684ctl) will not work in this case as the interfaces use different layer 2 encapsulation (e.g., atm0<=>eth0, or

Hello, I am running linux red hat 7.2 and still somewhat unfamiliar to its commands. I am administrator to an ISP with about 80 clients and would like to regulate the speed of uploads and downloads. I understand that I need to place everybody in different class''. Could I get help how to use tc/QBC to limit bandwith and impliment a u32 (or fwmark) filter that names mac

Hi, I have a 3Mbit (up,down) connection going through a Linux box (Debian 600mhz, 500mb ram) using NAT to approx 125 users. Presently I am shaping by marking packets by their port numbers. I''m prioritizing 22, 23, 25, 80, 81, 110, 443, 500, 3389, 1214, 6881:6889, etc, into their appropriate classes depending on weather there getting more or less bandwidth. This has worked pretty

Hello, I have configured advanced routing with success using three (03) network adapters ( ETH0, ETH1 and ETH2). Now I have to configure an addittion range in the same Interface ETH0 ( another internet ip range address ), so I would like to have TWO different ranges at the same ETHERNET CARD ( in this case ETH0 ) AND having advanced routing running it. I Did the same

Does anyone have a recommendation for an Open Source IP Address Management solution please? There are several commercial players such as BlueCat, BT Diamond, InfoBlox, VitalQIP. And, Solarwinds makes a module that focuses on IPAM. Most vendors tie logic into DNS and DHCP into IPAM designs. In any case, does anyone have awareness of an Open Source solution? Thank you Tom -------------- next part

Thanks Atin. Peer probes were done using FQDN and I was able to make these changes. The only thing I had to do on rest of the nodes was to flush nscd; after that everything was good and I did not have to restart gluster services on these rest of the nodes. - Hemant On 10/30/17 11:46 AM, Atin Mukherjee wrote: If the gluster nodes are peer probed through FQDNs then you?re good.

I''m trying to use ip route to setup a single interface with two ip addresses. I currently have: / # /usr/sbin/ip address show 1: eth0: <BROADCAST,MULTICAST,UP,10000> mtu 1500 qdisc pfifo_fast qlen 1000 link/ether 00:19:03:00:27:10 brd ff:ff:ff:ff:ff:ff inet 128.0.0.1/16 brd 128.0.255.255 scope global eth0:1 inet 172.17.31.84/24 brd 172.17.31.255 scope global eth0 2:

Hi, [sorry for the crosspost, I don''t know whether this is a routing or ebtables problem] I want to redirect all HTTP traffic passing through my bridge to a squid proxy on another machine. However, setting up brouting as suggested in the ebtables examples doesn''t work and the packets get dropped on the floor completely. /\/\/\/\/\/\/\/\ +----------------------+

If the gluster nodes are peer probed through FQDNs then you?re good. If they?re done through IPs then for every node you?d need to replace the old IP with new IP for all the files in /var/lib/glusterd along with renaming the filenames with have the associated old IP and restart all gluster services. I used to have a script for this which I shared earlier in users ML, need to dig through my mailbox

I guess at least some of you here work in an ISP or perhaps are working with a big network. I''m curious if you use some software for IP managment - noteing what ip addresses are used and where, what subnets are given to which customer etc.? Also I need some software like inventory of servers, routers ... that will hold information about hardware, software and services of each computer.

Reading along the Net it seems that MAC marking is not working with egress HTB (because ipables marks packages based on --mac-source ). So my only choice is using ingress or u32.
