Software Installation Problems! -- Linux general technology-Linux technology and application information. For details, refer to the following section. I use fedora 9. Because I want to test routing, I have a software named gns3 (rarely used, usually used by professionals). I won't install it. Please tell me how to install it. Please help me with the software in my attachment. This software is very important and I have installed it many times. Downloa

" three books to choose, combined with their own understanding of these times, through the GNS3 to build the relevant network environment to carry out the relevant agreement analysis, I believe this will definitely be a very good experience!When I was writing these posts, I was in the reality of my personal device, The operating system environment used (including the operating system environment of the virtual machine) is mostly Ubuntu15.10, while tak

OverviewThe network is configured with Vlan,vlan to isolate the broadcast, while the DHCP protocol uses broadcast, that is, by default the DHCP protocol can only be used within the VLAN, the DHCP server in VLAN30, only the client in VLAN30 can obtain the IP address from the DHCP server. What if the client of VLAN 2 or VLAN 3 also needs to get an IP address from this DHCP server?Solution Ideas1, to install a DHCP server for each network segment, but this way there is a waste of resources, and is

Instagram has improved mobile phone cameras, allowing users to take photos and process images. In addition, it also allows users to easily upload images

Installing GNS3 in linux is a very painful task. Since it is different from dynagen in form, you should not review the content. In fact, using dynagen is also flexible and convenient, you only need to know what you are doing better than using gns3. 3640 is a frequently used vro, because it can install the switch module, it is also very convenient to create a switch. It looks good to use dynagen for a few da

shows that we have also received the hello packet from our neighbors and tried to send the hello packet back directly. The figure below shows that, said our direct hello package restrictions, but also can detect very good fork, this is done in GNS3 phenomenon, on the WEB-IOU, may see the phenomenon content to the extent that: I have sent it two hello, it sent the hello packet neighbor field is still not Lao Tzu, look down on me, then I do not send, t

Translation to: Http://www.linuxjournal.com/content/non-linux-foss-virtualized-cisco-infrastructureWe're all familiar with the concept of virtual machines, and they're not just a great way to take advantage of server space resources, they also allow you to create and delete servers in an instant. It's perfect for a lab and training environment. Unfortunately, creating training experiments for Cisco hardware is always painful. Thanks to GNS3 (graphical

The following environments are used: Network device Simulator: GNS3 Grab Package software: Wireshark 1. Network Environment Construction For the sake of brevity, there is not a large network environment to meet the needs of the previous four cases of ARP packet analysis, but in the analysis of different ARP

this, Toad believes that not long before the small partners will play retreat. Because this insists on not coming down, encountering a big difficulty, it is easy to let people give up, give up on nothing, the former also white learning. Toad felt that any thing the best teacher was interested in, and how to mention small friends interested in it? I think this is the trivial thing, looking at the feathers of the ground we also know that even the Linux,windows,mac OS these cool operating systems,
