I am trying to connect my Ubuntu PC with gns3 router using loopback interface tap0, I am trying to configure the ip address of tap0 by using gns3 router as DHCP Server. But I am finding it difficult to do so.
View 2 RepliesI'm using GNS3 in order to revise CCNA, the RIP part But I don't know why, i'v got a pbl with the routage table, especially with the metric which is wrong I don't understand wy the metric is always 1, because it should be 2 or 3 according to the network.

View 2 Replies View RelatedI have managed to simulate to Cisco ASA's on GNS3 - ASA1 and ASA2. ASA2 is configured as multiple mode to enable contexts while ASA2 has been configured as single mode.
On ASA2 I can assign an IP address to its gigabitethernet interfaces as normal, however I'm unable to assign an interface to the gigabitethernet interfaces on ASA1.
I've got threeLinux Boxes (running Centos 6). They were all connected to my cheap WRT54GL-- DHCP worked every time.Absolutely no problems. Both the LInux boxes and the WRT54GL had MTU set to manual, 1492.I replaced the WRTt54GL with the expensive E4200. I set the new router's MTU to manual, 1492. NONE of my Linux boxes ever receive a DHCP address. I look at the logs, and they do DHCPDISCOVER, get DHCPNACK, try several different intervals, and then fail the interface and quit.ALL I did was unhook cables from the WRT54GL and plug into the E4200. Yes, the WRT54GL was powered off. NOTHING was changed in the Linux configs. Yes, DHCP is enabled, address-range assigned, etc. BTW-- one box is dual boot with Win7-- in Win7 (using the same card, obviously), DHCP works just fine. But, Linux doesn't work.
I can give the boxes static IP's, and all is well. Just can't get DHCP to work. I evfen tried putting in DHCP reservations (via MAC assignments) for the E4200-- still doesn't work. The new E4200 is on the 02 firmware (which I believe is cuurent). If I can't iron this simple task out, in a couple of days I'm taking the E4200 back, and getting a refund. I'll stay with my old WRT54GL... it works. Hate to give up on some of the new E4200 features, though.

I have not worked on the new VWIC cards lately. I would like to know how I can configure the serial IP address like we used to do in the older T1 DSU WIC cards. I do not see any interface that shows as serial. I have configured the controller as a T1 controller but still no luck.

“Invalid IP Address Format”

We are using an ACE20 module running version A2(3.2).I have a question regarding IP stickyness and the timeout parameter.I found this in the "Server load balancing configuration guide" (in a section entitled: "Configuring a Timeout for IP Address Stickiness"):
"The sticky timeout specifies the period of time that the ACE keeps (if possible) the IP address sticky information for a client connection in the sticky table after the latest client connection terminates. The ACE resets the sticky timer for a specific sticky-table entry each time that the module opens a new connection or receives a new HTTP GET on an existing connection that matches that entry."
The parts in bold seem to point to the fact that the timeout is an "inactivity timeout" as the counter is reset on every new connection.The next section in the documentation is entitled: "Enabling an IP Address Sticky Timeout to Override Active Connections" and says:
"By default, the ACE ages out a sticky table entry when the timeout for that entry expires and no active connections matching that entry exist. To specify that the ACE time out IP address sticky table entries even if active connections exist after the sticky timer expires, use the timeout activeconns command."
This seems to contradict the previous statement.So my question is: is the IP stickyness timeout an "inactivity timeout" or not?
As a Cisco newbie I am thinking about building a linux router (for a study project) to connect to a Cisco network (2 x 1841 routers). what kind (standard) of serial interface card will I need to install on the Linux PC router to enable serial communications with the other two 1841s.
View 2 Replies View RelatedWe have small which I'm looking to implement and have built this on GNS3.
We have:
Router A in site 1
Router B in site 2
Router C in site 3
Router A and B are connection via a point to point 100M link and from Router C we have a 2 point to point one of which is 5Mpbs and going to Router A and Router B.
For Router C to reach Router A network it will go via Router B and these are 100M connection. When the link between Router A and B goes down. Router C should update and start using the 5m route.
For some reson, the routes are not updating. I have to do 'clea ip eigrp ne' for the routes to update and if I reload the routers all works well, it seems the problem is intermittent.
is it possibe to set up a ubuntu linux PC on a linksys wireless router? linksys says "no". also where would I get the printer, wireless card, and sound drivers. it's a dell latitude running a pentium m (yeah, i know).
View 10 Replies View RelatedI'm a Linux user and just got a new Linksys E2000 router. I attached the router to the computer with the Ethernet cable, and switched the router on, expecting it to work as DHCP server by default, so I could access routers configuration and set it up as needed. This however failed right away. Obviously the router didn't start DHCP, even after I reset with the reset button on the back. Now there is no way to accesss the router to configure it, since web interface path relies on router's DHCP function to access it through 192.168.1.1 which is not working. What can be done to enable it?

I want to ping my GNS3 routers from my real LAN PCs. Right now I am able to ping those GNS3 routers from real PC on which GNS3 is installed. The network topology is something like this.
-IP of GNS3 PC on which GNS3 is installed. 192.168.1.102/24 default gateway of LAN: 192.168.1.1/24
I have created a loopback adapter and assigned the IP address of 192.168.1.200/24 (IP is also of same LAN) the cloud and virtual router is dragged and router interface is assigned the IP 192.168.1.201/24. I am able to ping my router interface from 192.168.1.102 (System on which GNS3 is installed). What I want is to ping my router's interface from other LAN PCs line 192.168.1.104, 192.168.105 or from my gateway 192.168.1.1.

I recently purchased a Cisco-Linksys WRT54GL Wireless-G Broadband Router from Amazon. The specs indicate it's Linux based: [URL] I checked other sites, and found the same claim: [URL] and [URL],But, to my dismay, when I was configuring and viewing the logs of the device.
View 3 Replies View RelatedOk, so what I want to do is make a router/firewall/proxy (maybe add webserver/FTP as well). Just to start off I want to say that I have moderate knowledge of Linux, enough to administer it from the CL. I have setup routers before but it was years ago and I've forgotten some of the details involved. What I do is a base LAMP install, with DNS, Samba, DHCP server, OpenSSH and then Webmin for easier administration. I've also installed EHCP (easy hosting control panel) in the past but have not at this point.
So, what I want to know is how do I setup the NIC's in the etc/network/interfaces file. Let's say that eth0 connects to the modem and eth1 & 2 are internal adapters. Currently my network is running a Linksys WRT54GL with DD-WRT and the router is set to DHCP for the WAN connection and DHCP is running on the internal network as well. The modem is at 192.168.254.254 and is giving the router an address of 192.168.254.1 my internal network is 192.168.1.1 (192.168.1.0/24). I would like to setup my internal router address to 192.168.1.1 so I guess I need to set it to static in my interfaces config and then set my eth0 to dhcp. Does this sound correct?
So if I do the above my only question is how do I setup the routing tables after that? I always get messed up when I need to make the switch from my Linksys router to my Linux box. I'm not worried about firewall rules at first I can change those once I have the router up and running. I just don't know if I need to make some kind of bridge to bridge the eth0 and eth1 (external NIC and internal NIC).
I get an IOS image for GNS3? I dont work in a company that would do that for me
