Protocols / Routing :: Users Internet Connection Based On Their Username Or Group In A Windows Environment?

Jan 12, 2012

I'm looking into a way of routing users internet connection based on their username or group in a windows environment. Currently there's two ISP connections with their own proxy server. I want a user to be fully redirected to one of the ISPs based on who they are. I was hoping via IE proxy settings, this can be accomplished, but it looks like the primary ISP connection, is still getting most of the connections/routing.

Virtual PC Using Different Internet Connection Then Host?

Feb 2, 2011

Running a Windows 7 laptop plugged into a LAN using ethernet cable with internet.The built-in wireless nic on the laptop connects to a totally different internet network. I set up an XP Mode Virtual PC on the laptop with the intention that it would use the wireless internet connection.I set this up by installing Microsoft Loopback Adapter, then sharing the wireless nic to it. The Virtual PC is set to use the Microsoft Loopback Adapter as its network connection.My problem is that only the hard wired internet connection works.The wireless is connected and has an ip address, however no traffic flows through it until i either disable the cabled network or physcially unplug the cable. Is it possible to have my host laptop use the cabled internet connection and my virtual pc use the 2nd wireless internet?

Ethical Considerations Hacking A Virtual Environment?

Nov 1, 2012

I am currently finalising my project in Uni and in the project planning section is asks if there are any ethical considerations to be made in my project. I am conducting penetration testing on a VIRTUAL network simulator (GNS3) using Metasploit toolkit. I am guessing I will need permission to download these tools onto the university network, would that count as an ethical consideration? If not, what would I say in this section? note, all of the data I am using in the project was created by myself, and there is no other human participation.

Protocols / Routing :: Network Host Ip Cannot Be Changed

Oct 23, 2011

We have two networks in our lan: 10.0.0.0/24 and 192.168.1.0/24. Actually the networks are separated. The 192.168.1.0/24 network contains some hosts that ip can not be changed. We want redesign the network and communicate with both networks without routers. I thougnt about changing the netmask for 192.168.1.0/24 in 192.168.1.0/22 (1022 hosts) and change IP's in the 10.0.0.0/24 network in 192.168.2.0/22.

Protocols / Routing :: Why Would 10.1.1.1/24 Router Communicate To 10.1.1.2/8 Host

Feb 19, 2013

I am just confused over the fact that a router configured with 10.1.1.1 address (assuming it's got 255.255.255.0 mask) can communicate to a PC connected to one of it's LAN ports and manually setup to have 10.1.1.2/8 address. I was sure that since these are two different subnets they won't see each other. But they do and searched wiki and just googled to see why, but with no success. A friend of my friend says something about 'same range' but it makes little sense to me.

I just need a good article about it or a crystall clear explanation, because I feel my understanding of IP is not as good as I used to believe.

VIRTUAL MACHINE ~ Can Guest OS become Infected Through Host OS ?If I setup and use a virtual machine running/containing both a Host OS and a guest OS ... do they remain completely separate entities when operating one or the other?My main concern is Virus related ... if for instance I'm Running Windows 7 as the host and XP as the guest and I get the host OS infected, will the guest XP OS also contract it by default because it is operating on the same disk?

D-Link DIR-825 :: Port Forwarding Or Virtual Host?

Jan 11, 2012

One of the persons involved in a home network has installed a Dlink DIR-825 Rev-B Extreme router on the Comcast cable system to allow a 'better' wireless signal on upper floors of the home. Two others involved in the same home network use a 'secure desktop access' software called NetOp to access the network remotely.  To facilitate this software, we must 'port forward' port 6502 on BOTH UDP and TCP to the single system that is accessed. 

However, this setup (simple port forwarding) does not seem to work - neither does 'virtual server', for that matter.  Prior to this router being installed, it was extremely simple to accomplish this remote access using a Linksys router, so our software firewall configuration has not changed but the new Dlink seems unable to allow remote access.

How (and via which of these access methods - port forwarding or virtual server) would be best? This configuration seems frustratingly difficult to accomplish and I'm about to take the Dlink 'out' of the network and re-install the Linksys with a 'high-gain' external antenna to facilitate simple signal enhancement.

Windows 7 - Connect Virtual Machine To Host Via IEEE1394 / USB Or Serial Port

May 15, 2013

I have a host machine (Laptop, Win 7 Home Premium x64) running Windows 7 Ultimate x64 on VMWare Workstation 9. I've got this system set up for UMDF driver development, because I need a target machine to debug drivers on. However, because I'm developing drivers for Win 7 (x86 and x64), I cannot connect to the virtual machine on via a simple network connection. Connection methods are outlined here.

I have tried a few different pieces of software (mostly Eltima software), and have Google'd every combination of phrases that I can think of. I can't find any information on this anywhere. I don't just need to share data between the machines, I need a more "physical" connection.

Does any know how to do this, or if there's another (preferably more simple) way of doing it?

Protocols / Routing :: Connection Keeps On Dropping Randomly?

Oct 25, 2011

I am running Windows Vista Business SP2 and I have been having problems lately with my internet connection. I am on a DSL connection and my computer keeps on dropping the connection like every 15-20min in order to get my connection back I have to disable and then reenable the network connection, but the weird thing is that I don't get internet connection, but I can still send and recieve IM's and Mail when my internet goes down. It is not my ISP that is wrong , but my computer, because I have a windows xp and it does the same thing and I also have a windows 7 PC and that one does not lose connection when my other ones do. On my Windows XP all what I have to do so it gets connection again is click on the connection and then click repair and I get internet again, but Windows Vista does not have this option so I have to disable and reenable my connection

Protocols / Routing :: Cisco E2000 Has No Internet Connection

Mar 20, 2011

We have Linkline ADSL that was set up by them with a Netopia 2241N-006 modem and a Cisco 33674 wired router. We got a Cisco E2000 wireless router to replace the wired one. It sets up perfectly, in that I can see and connect to the wireless router just fine, but it has no Internet connection. Also, when we plug the cord straight from the modem into the computer (as was suggested by someone) it has no Internet connection, so it seems we need the Netopia modem for it work.I have connected to Cisco live chat three different times to try and find out how to make this work, and each time after making me give them all the information they insisted the uninstalling/reinstalling Cisco connect and then going through set up again it would work. On the second and third chats I even gave them the reference numbers for the previous chats so theiy could see that is what was already done, to no avail. Apparently that is the only solution they know.Then I called Cisco support on the phone (twice). The first time they insisted I hang up and I repeat the same procedure from the chats, even though I explained I had now done it three times and gave them the chat reference numbers. They said if I would not do that. The second time I called they told me that was not something they supported - using their router with an adsl modem - even though their instructions do cover it.

using the two routers together since I cannot get the wireless one to work alone. I went and bought a crossover cable, hooked the two routers LAN port to LAN port, changed the router's IP address to just outside the main router's range and disabled DHCP. This did not change anything, so I tried the one other idea I found online which was to assign the router a static IP address in the same range that the rest of the network is using, hook the two routers LAN port to LAN port with the crossover cable, and disable the DHCP. This did not work either.

Cisco Switching/Routing :: Nexus 5000 Esx Host Lose Connection To Net-App SAN For 10-16 Seconds

Dec 4, 2011

I have two 5000. Uplinks are Vpc to nexus 7000 and downlink are connected to Esx host. When I reboot one 5000, some Esx host lose connection to the NetApp SAN (Iscsi and CIFS) for 10-16 seconds. This is enought to generate errors and event corruption on disk. The 10-16 blackout occur when the switch as reloaded.
 
My theory is that VPC interface comme up 10-16 seconds after the edge interface(ESX). This create a blackhole effect for ESX host.

Cisco Switching/Routing :: Nexus 7010 - Inter-VLAN Routing On Multilayer VPC Environment

Feb 16, 2011

you find attached my network architecture with 2 Nexus 7010 on core layer and 2 Nexus 5020 on distribution layer, each one with 1 N2148T fabric extender switch. PC-A1 and PC-A2 are connected to one N2148T, PC-B1 is connected to the other N2148T. Nexus-7000-1 is HSRP Active for all VLANs, Nexus-7000-2 is HSRP standby. PC-A1 and PC-A2 are connected to VLAN A, PC-B1 is connected to VLAN B. PC-A1 and PC-A2 have the same default gateway correspondent to IP HSRP on VLAN A. It happens that PC-A1 is able to ping PC-B1 while PC-A2 is unable to ping PC-B1. If I issue a traceroute from PC-A2 I see Nexus-7000-2’s physical IP address as the first hop even if Nexus-7000-2 is HSRP standby. After the first hop the traceroute is lost. If I shutdown Port-channel 20 on Nexus-5000-2, PC-A2 starts to ping PC-B1.I can’t understand what’s wrong in this architecture.

Cisco Switching/Routing :: Upgrade 6509-Chassis In VSS-Environment?

May 1, 2013

we have some pairs of 6509-VSS, which partially have old (no more officially supported) 6509-Chassis.All linecards in the VSS are the same (Sup 720-10GE-3C, 67XX).
 
We now bought some new 6509-E-Chassis and want to change the old chassis by the new ones in a ISSU manner, that means:
 
1. putting the partner, which chassis changes, in redundancy mode, switch it off, exchange chassis (old "Catalyst 6509", new "Catalyst 6509-E")

2. inserting the line-cards exactly in the same slots and connecting all cables

3. switch on the new chassis, witing to come up in VSS
 
I'm not sure of having to set the switch number for VSS (is that in the Sup?; configuration? or part of the chassis-memory?)
 
I've looked up cisco for some hints, but don't found anything.

Cisco Switching/Routing :: 3560 / 3750 - Enterprise LAN Environment / Could Not SSH

Feb 1, 2012

I am working in an enterprise LAN environment. We have about 100 switches, mostly 3560 and 3750's. This is a typical Cisco network, yet it's flat. No routing on the access layers. The core switch does do the routing. We use an third party vendor network monitoring tool, and we use Secure CRT to remote into devices.

Here's the problem. There was a device we stumbled into that had not been put into our monitoring software. It has the same IOS as our other devices. All I can say is that it's the same version and type. Each device has a management v LAN. And each device has it's own management IP. An ACL exists to prevent unauthorized SSH access into the devices, yet allows the management v LAN scope to get in.
 
So, here's the problem...we can't SSH into our problem mystery device, let's call it Switch X. Switch X has an IP of 10.10.100.150. Now, I can be logged into it's up link device, let's call it switch B. Switch B has an IP of 10.10.100.130. The ACL allows all devices from 10.10.100.0/24 to SSH. Our PC's at our desk are also in the same management V LAN. SSH version 2 is on the configs, and the domain names are the same on these two devices.
 
So, let's be clear. From my desktop, I can connect to any device on my network EXCEPT switch X. When I try to connect using SSH, port 22...it just sits there until it times out. I can do the same thing to any other switch, and connect just fine. We are using TACACS+ and RADIUS as well, and they are up and running just fine. The configs on Switch X like I said are the same for switch B, except it's IP address of course. While logged into switch B, I can do a CDP neighbor and see switch X connected via trunk link. Both sides are running dot1q encapsulation, and both are in trunk mode. I can ping switch X from switch B. When I try to SSH from B to X..I get timeout with no connection.
 
So, I hiked over to the building where switch X is located. I consoled into the switch. I confirmed that the ACL is the same as the ACL for switch B. It is set up to allow the management v lan inbound on the VTY 0 - 15. Yes, it's access-class (name) in on both vty 0 4 and 5 15. It also is set up for transport ssh in and transport ssh out.
 
I rechecked the domain name on Switch X; it was correct. I also did a crypto key and regenerated the crypto key. SSH v2 came up. Again, while in Switch X, I can do a CDP neighbor and see switch B. But I cannot SSH from switch X to Switch B, or any other devices that I tried. Now, we did find a config error with VTP; the VTP domain name was different. But VTP has nothing to do with SSH. Just to placate my co-workers, I went ahead and renamed the VTP domain name (it's running transparent mode). After I regenerated the crypto key, I saved everything of course. I then reloaded the switch. When all came back up, I still could not SSH
 
This is a 3560 switch, and it is trunk to a 3750.

Cisco Switching/Routing :: Connecting 3750 Switch To Avaya Environment

May 3, 2012

I'm introducing a Cisco 3750 switch into a Avaya environment for testing/lab. I'm concerned about any STP, VTP problems I might create as I'm going to give a address on the Management VLAN and connect it to a trunk port on a ERS5520 Avaya. I've set the switch to transparent mode and the VTP revision is set to 0. I've checked the STP priority but it doesn't give any - there is no output because it is not connected. I wouldn't be so concerned but, I'm not sure if any config has been on it before.Also, is there any way for me to see the STP prioroity without having it connected?

Cisco Switching/Routing :: 3560E-24TD And IGMP In Layer 2 Environment

I have 3560e which doesn't appear to be passing igmp traffic to the upstream router
 
PC1 ----------- ASA ------------ PC2--------- 3560e ----------- 3825 -------------------- WAN --------------------- Router ------------- Server
 
My ASA runs SMR, has an igmp forward interface outside command on the inside and has a trunk port to the 3560e (V lans 32 & 48).PC2 is a test pc on the 3560e on vlan32. 3825 is my ISPs router on vlan32.
 
- if i try to access the stream from PC2 it works. 
- if i try to access the stream from PC1, i see the igmp join leave my ASA onto the 3560E (i've captured on the 3560e's link to the ASA). 

I've also captured on the ASA and i can see the igmp packet leave the outside interface but the join doesn't reach the 3825 (i've captured on the 3560e port facing the router and there is no join being forwarded).the switch is running in layer 2, 12.2(35r)SE1.
