Cisco Infrastructure :: 2509 - Create The Virtual Com Ports On Windows And Linux Machines?

Sep 5, 2011

I recently acquired a 2509 router that I plan to use as a serial device router.  My question is, how do you create the virtual com ports on Windows and Linux machines to point to the TCP address:ports in the 2509 router?  Is there software or drivers that do this?  Or something third-party?

Lost Internet Connection With My Virtual Machines

Feb 18, 2013

Implement the procedures required so that machine 1 and machine 2 can communicate statically with one another. Outline the TCP/IP settings to be used on each of the machines and set this machine up accordingly.

I followed this guide [TUT] Setting a static internal IP (Windows and Linux)but what has happened is that now the two machines can't connect to the internet.

Cisco :: 5508 Virtual Machines With Bridged Connection / No IP From DHCP?

May 31, 2011

We are experimenting with virtual machines running on some laptops here as part of a future deployment.Equipment in use:

-5508 WLC
-1262 LWAP
 
The actual operating system has no issues connecting to the wireless. When you start the virtual machine on any client machine (OSX, Win 7, Win XP, anything) it is unable to get an IP through an external DHCP server when the VM is set up to use a bridged connection.This works fine with Autonomous access points and over cable all mapped to the same VLAN. Helper addresses are configured on the VLAN.Is this a limitation of the WLC where it cannot provide more than one IP address per MAC? Is it a limitation of CAPWAP? Or is there an option to turn of DHCP snooping (which I suspect to be the cause of the issue)?

D-Link DIR-655 :: Why Is Loop-back Only Working On Ports Forwarded In Virtual Server Section

Nov 4, 2011

Why is loop-back only working on ports forwarded in the Virtual Server section and not Port Forwarding or even DMZ? I have seen a post about loop-back on the DIR-655 from a while ago that had said to disable SPI and change NAT Endpoint to independent, I have done this and loop-back still doesn't work.

Networking XP Machines - Can't Log In?

Feb 22, 2011

Running Windows XP Im a bit Dizzy as i can't seem to workout what's going wrong or what im doing wrong lol!!!8 Pc's on the network, all can view files etc.apart from one Pc Lets just call this "Bob1"It keeps asking for user name and password, now there's no user name or password on the giving pc, file and sharing is open and all the right ports giving. what i can't understand is that the reaming 7 pc's on the network has the same setup and files permissions, on the same subnet and can ping each other to my knowledge.So just to prove myself wrong i made a password for the pc that was asking for one on the network and this still did not work.so to cut the story short 7 pc's can search each other fine but on "Bob1" keeping asking for user name and password.

Blocking Facebook On All Machines Except Two

May 10, 2011

I am using a linksys router that is generating IP addresses to about 20 machines. The boss wants to block FACEBOOK on all the machines except for two machines? Is this possible? I was thinking even if we block all the machines and get a work around password (only given to the owners of 2 out of the 20 computers).

Cannot See Shared Directories From Other Machines

Jun 25, 2011

On my home network, I have several shares on my PC. But I dont seem to be able to even view the shares from other machines. If I put the IP address into an explorer window (\192.168.0.4) on another machine I get the message: "\192.168.0.4 is not accessible. You may not have permission to use this network resouces. contact your network administrator etc etc". So I cannot even bring up a directory list. There are no problems for me connecting to network shares on other machines from this machine that is refusing connections. That has all happened since I reinstalled windows. I reformatted the system partition and since then I cannot get the shares working again (they used to work fine). The shares are in a data partition that was not reformatted. This is really winding me up, as there never used to be a problem, and I cant think of anything else to look into, short of delving into the registry, and I wouldnt know where to look.

One Server Can Only Access LAN Machines?

Feb 14, 2011

One of our servers has lost the ability to access WAN side computers. For example, it can't ping google.com. It can, however, interact with LAN computers. One thing of note -- it is set up with a static IP and one-to-one NAT on the firewall (sonicwall)When we disable the one-to-one nat on the firewall the server is able to ping out. We do need to keep the one-to-one nat up though -- as it provides access to the site the server hosts

How To Create Network Bubble With 4 Machines

Apr 12, 2012

I need to create a network bubble..means..Let say I have 4 machines having IP address 10.1.1.1,10.1.1.2, 10.1.1.3 and 10.1.1.4 (these are not actual IP's, using them just for explaining). These machines are connected to public network. At a given point in time, I need to isolate these machines from the public network in a way where - All these 4 machines can talk to each other using the assigned IP's. - These 4 machines cannot talk to any other nodes in the public network. no other machines outside these 4, will be able to ping these machines.

Time On Client Machines On A Small LAN

Connect Windows XP Machines Together Without Domain

Oct 26, 2011

I have 3 machines running windows XP, they all belong to my company's domain. These machines have to leave our office but still have to be able to connect to each other and share a few folders on each. I used to do this all the time. I would make sure to turn on the "Server" service, set the windows firewall to allow File and Printer sharing, set the File and Printer sharing setting in the Local Area Connection properties, and set the proper sharing/security of the specific folder. Then as long as each machine used a specific local logon name that was the same on each machine, they would all connect to the shares and work perfectly.However now, I seem to not be able to get any of this to work on machines that have service pack 3. Is there something in sp3 that breaks this?Isn't there a way to still share files on these sp3 machines even though I'm not on the domain? (without changing the domain membership)

XP Pro Machines Can't Access Data On Windows 7 PC

Jan 18, 2011

I'm having problems in a mixed XP Pro (SP3)/Win 7 Pro (64 bit) network getting the XP machines to access data on the Win7 box. The XP machines are connected wirelessly to a D-Link DSL-2640R router modem and the Win7 machine is connected via an Ethernet cable.

Internet access from all machines works perfectly.The two XP machines can see each other either via mapped drives or My Network Places and can access files.The Win7 PC can access data on both the 2 XP machines.All machines are part of the same Workgroup and the network is set up as 'Office' on the Win7 machine.The XP machines can see the Workgroup, including the Win7 machine after I changed the network type from Home to Office, but can not access the data on it.I assume this is a permissions problem on the Win7 machine. I've made the root directory of the HD in the Win7 machine shareable as \Hppro3125hd via Advanced Sharing/Properties and in the Advanced Sharing tab I have set the permissions for Everyone to Full Control.

There is only one user (Garry) explicitly set up on the Win7 machine. I've tried connecting to the Win7HD via a mapped drive on each of the XP machines by logging on as a different user i.e. matching the user name from the Win7 machine but still no joy.Is there an easy to follow step-by-step guide to lead me through the necessary steps to allow the XP machines to access data on the Win7 box?

D-Link DIR-615 :: Logging Activity On All Machines?

Jan 4, 2013

I am wondering if I can log all activity on my network.  Right now I can log activity with MAC addresses, but if I add a device I have to keep adding MAC address.  I also have to have several policies because I can only put about 7 MAC address in per policy.

I noticed the option to add 'other machines' and I am not sure how this works.  I have tried it and can't get it to work.

D-Link DIR-655 :: Get Machines To Connect To Mac Mini Through SMB

On the inside are DHCP systems.  On the outside is my server.  I cannot seem to get the inside machines to recognize my file shares outside the dlink.  The outside server is a MAC mini.  Any machine outside the server can see the file shares (regardless if they are a Mac or a Windows PC - So I know that SMB is set-up properly).How can I get the inside servers to see the file shares on the outside machine?

Cannot Establish Connection Between Wired And Wireless Machines

May 7, 2011

Once again the sun sinks into its nightly reprieve; for the third time since I first set out on this mission. Before me, only the piercing glows of monitors that sting my eyes. Yet, I cannot look away. The clacking of keys, once triumphant battle drums of purpose, has grown sharp. They pierce my ears and my mind. It would be madness to continue. My body is weak. My resolve is waning. My sanity ...... tenuous. But if seeing this through means madness.....bring on the madness.

I'm trying to find a way to network my desktop (wired) and my laptop (wifi) so that I can swap files between the two easily. I've mostly been attempting this through Windows Homegroup, although I've also downloaded and installed TeamViewer. The thing is, the two just will not connect. After much poking around I found the specific symptom to be that wired connections and wireless connections refuse to speak. My laptop sees my roomie's laptop easily enough, though. And if I hardline my laptop to the router suddenly their best friends! - joining each others' Homegroup, swapping files, trading recipes!

Points of interest: I've noticed that, while both are enabled, only IPv4 connectivity indicates internet access; IPv6 says No Internet Access. Pings from one machine to the other result in "Request timed out" or "Destination Host Unreachable." I've disabled firewalls - Windows and the one on the router. Disabled and then uninstalled anti-virus. I've updated the router firmware and net adapter drivers I tried restoring router to factory settings, in case I changed something I shouldn't have along the way. I've alternated static and dynamic ip addresses - no difference there. I've just spotted a couple of errors in the Event Viewer that look like they could be leads;(!)ErrorDhcp-Client The IP address lease 192.168.2.2 for the Network Card with network address 0x6CF049E337F0 has been denied by the DHCP server 192.168.2.1 (The DHCP Server sent a DHCPNACK message).

XP Machines Unable To Connect To Windows 7 Shares

Jan 26, 2011

I have a Windows 7 machine sending shares across the network. Other Windows 7 machines have no problems connecting, but XP machines cannot connect. (Win7 can connect to XP shares).

I have adjust every setting that I have seen to no avail. This includes turning off HomeGroups, turning off password. Removing my password from my user account. Adding "Everyone" to each of the shares. I have even messed with the Local Group Policy Editor to send unencrypted passwords to third party SMB's.
