Host Names And IP Addresses?
Sep 30, 2011
I have been asked to do is locate some computers on the network and run a security scan on them. Well i pinged the host name and got an IP address. Then the network admin me look up the switch port that the computer is located on and so on. So i find 3 of the computers im looking for and when i get on the computer and look up the name but it does not match the name given to me. So i do an ipconfig /all and see that the computer has the right IP address and MAC address but not the same name. So my main question is, are these computers one in the same or is something messed up?

Is it possible to give me NAS and Xbox 360 Host names so that they show up in my DHCP Client list? Currently there are 13 devices connected, 11 of which have a host name but these two do not. It also shows the IP and MAC addresses of each connected device.I just want to make sure that all of the devices that are connected are what I would expect.

where the host names do not properly resolve with the right ip address.Example, I ping a host name, it gives me an IP, but when I VNC into the workstation, it is a totally different host.

I have issues with the same host name duplication in different VLAN's in the same domain.Scenario:I have 2 VLAN's named VLAN A and VLAN B.If i assign in VLAN A for one of the computer name as Comp1 it's not in the network so its accepting.in dns will be replaced with VLAN B and if i ping i can see the ip also from VLAN B.

I was thrown into trying to fix a friends pc being told that the internet wasn't working.What I've found through some messing around is that I am able to pull up websites with the ip address but trying to use the domain name give a "Host Not Found". Similar error when trying to do a ping. However doing an nslookup will pull the ip's for a domain. I've done the dns flush, the netsh commands that are floating around to no avail.

Anyway, I am looking for a way to discover host names of Apple devices (namely iPods and iPhones) that are on our network. I've tried a number of programs like Nmap, Advanced IP Scanner, and LanSpy to name a few. All of them will report back the MAC address with no problem but no dice on resolving the host name.
My goal is to use the host name to identify the device, and ultimately the person with the device. Any thoughts on how I can go about this? Is there a setting in Nmap I'm missing or perhaps a better program to use?

I'm having with my VPN Server on my Cisco 2621xm.
I started by creating a VPN - everything worked great. I assigned the DNS Servers, Domain name, WINS Server so when I connect I'm able to resolve local hostnames on the network with no problem, however, I had no internet access... I then set up a split tunnel access list. Since I've set that up, I'm now able to ping internet based addresses url... but no longer able to resolve internal host names. I can ping the ip addresses, just name resolution no longer works. [code]

I am able to connect to corporate VPN with no issues when connecting directly to ISP modem. When I try to complete the same VPN connection via a Wireless Router (Linksys WRT160Nv3) i get the following message: "Network error. Unable to look up host names"I have tried connecting and it will initially connect, but 15-30 seconds it will drop and connection can't be re-established.Is there a setting on the Linksys WRT160Nv3 that needs to be changed?

I ran into a very interesting problem that occurred today and I'm trying to figure out why it happened. If it was one ASA 5505 that just required the reboot, then I'd have just chalked it up to a glitch, but when we built a new AD/ DNS server on the main network at the main site and changed the 3 Remote site ASAs to point to the new DNS server in the DHCPD options, none of them could ping any local host names to the DNS server at the main site they were now pointing too, but external host names { URL} all translated and pinged fine.
From a laptop on one of the remote sites, we could ping the new AD/DNS server(192.168.0.3) and the old AD/DNS server(192.168.0.2) and everything else at the main site, and telnet to port 53 showed successful across the Easy VPN from the Remote site to the new server at the main site. When wire shark was added to the new DNS server at the main site, the DNS request and replies for {URL}, for example, came and worked fine, but any requests for local resources never made it to the server from the remote sites.
A reboot of one of the Remote Site ASA's corrected the issue. Then I rebooted the other two remote site ASAs, and now DNS was working fine for everybody. I had also tried clearing the ARP cache on the ASAs before resorting to rebooting them. I also tried rebooting the laptop thinking the local DNS cache needed cleared before resorting to rebooting the ASAs. I'm struggling to understand why external, public host names made it through and resolved from the remote sites to the new server at the main site, but anything local failed before even reaching the new server(The new DNS server could resolve requests made by computers at the main site, but the remote sites that traverse the Easy VPN from the ASAs failed). The new AD/DNS server is the only server configured for DNS for all remote site computers.
Is any of this making sense? I'm wondering if clearing the x late or local host tables would have corrected it without having to reboot. I'm just trying to grasp the understanding here and figure out what happened.

In setup for old RV042 (V1), when updating / adding Mac addresses, the table is always sorted by IP addresses. But in the new oneRV042 (V3) I have, even with latest firmware 4.2.1.02 the list is random, thereby increasing the chance of user entering DUPLICATE IP addr with diff Mac addr. That will result in conflict.If the firmware sorts the DHCP entries by ip addresses, user would be able to catch duplicate ip errors even if the system does not flag the errors. All Cisco smart engineers can you all get the dhcp entries SORT by ip addresses.

I have a host that can successfully connect to a PIX 515E (7.x OS) via VPN Client; however, I have no IP routing to the LAN from the remote host.The VPN IP pool works finem,The LAN default gateway is the inside interface on the PIX; the network is flat L2 behind it.The default route on the PIX points out; no other routes are defined,The VPN remote host can be pinged from LAN hosts, but the VPN remote host cannot ping any LAN host, not even the PIX inside interface.

Just planning my move to 8.4(2) and I'm looking for some input. In the past, I have a text file with name commands for every host on my network that I know about. I would then deploy this list to all ASAs so that I could create ACLs on any firewall using a name, which would correlate to the same IP on any firewall.Now, the names from the name command no longer work as a host entry in ACLs, therefore I'm required to switch all of my active name command entries over to objects.My question is, have any of you found an easy way to change all name commands to objects? Since the name command doesn't specify the mask of the entry, I think this may not be possible without manually updating thousands of records. I know that once I migrate, there will be some objects auto-created, but those will only be host and or networks which have NATs associated with them.

I have an issue with LMS 4.1 where the DCR names of several devices repeatedly revert to the IP address. I am trying to stage some devices for deployment. The initial 5 devices were staged and are now off-line. A subsequent set of 6 devices is on-line and accessible from LMS4.1. The device names on the off-line devices are stable. The device names of the on-line devices revert back to an IP address every day. From device management, I go in and change the display name and the host name from the IP address to an alphabetic host name. When I go back and look at it the next day, it has reverted to the IP address.

1. I have a DSL modem + wireless + router
2. I have a Vonage phone that taps into one of the LAN ports
3. I have DIR 655 router that taps into one of the LAN ports
4. I have NAS that taps into one of the DIR 655 LAN ports
5. I have Printer that taps into one of the DIR 655 LAN ports
6. I have a BD Player that connects to DIR 655 through wireless.
All my components that are tied to DIR-655 resolve through IP address. I would like to have the resolution through host name as it works with my first router (DSL Modem / Router). Identifying components with IP address is not only inconvinient in terms of reading / recognizing my components but ther could be other issues. I am not very techie on the networking side but I do have some basic knowledge.

I'm using MAC address filtering on my network, and have no problem adding new devices as and when we purchase them. However, a lot of these items such as smart phones with wi-fi, Kindles etc don't seem to have a name that identifies them on the device info page. All of our laptops and desktops are identified, but none of the phones etc. Is it possible to assign names to MAC addresses at all?

In asus router model rt-n10, there is a client list when you bring up 192.168.1.1 showing names of devices also mac addresses and ip addresses. How do I add names to the list so I know which devices are using what ip etc. I have tried the advanced settings in the router to see if I can do it this way , but no luck.

Redirecting a Domain to a IP:Port I host game servers for friends and strangers alike, but i'd like to make it easier for them all and give them dedicated IPs. Right now I include domain redirecting, but to connect to their server, they have to put in "example.com:xxxxx", x meaning their servers dedicated port. Is there any way that I can redirect a domain directly to "IP:Port"?

How to configure ASA 5520 to resolve names in ASA's. We are currently using ASDM to configure network objects with the hostnames in the internet and then specifying the IP address . But this is done manually. Is there a different way of setting it up on ASA. Also when getting reports from ASA, we see the IP's but is there a way that we could add an identity to the IP's (reverse lookup)

I've just installed a RV042G router for the first time. The computers connect to the internet just fine, but they can no longer see each other through the Windows workgroup. I can ping the router, but not other computers on the net. The router doesn't seem to be sharing the names of the other computers on the net.

I'm not sure if this is a recent issue for our setup, but I've only just noticed it. Although most authenticated users are shown by their correct user names (which are required for 802.1x authentication), a few users show up in the WCS reports as "anonymous", and one as "anonymous@myabc.com", which are not valid usernames on our network.
I can track these users by MAC via our network registration database, but have not yet figured what makes their systems unique. All three in yesterday's report are Win 7. I don't see anything strange in the RADIUS logs, but have not yet caputured "debug" traces of wireless authentication from an anonymous user.
We are running WCS 7.0.172.0 , with a pair of WLC 4402 controllers running 7.0.116.0 . Our WPA2 Enterprise auth uses TTLS/PAP, with the SecureW2 supplicant for Windows.

just bought the EA4500 new, setup the router with computer plug-in RJ45, after I change my network network to "LinksysOne", I can connect to the network wireless. But when I connect it with hard wire/RJ45, it shows "cisco27205", but I cannot see "cisco27205" with wifi, neither with RJ45 connection cannot see "LinksysOne". Why this happen? is this normal?

I see that if I ask for 887va-sec-k9 I get an 887va with "advanced ip services" instead of the default "advanced security".
I can't see a corresponding part number for an 887va-w with advanced ip services. Is there one? Also, what would the part number be for memory to expand a va-w up to the max possible memory?
At a guess it would be the same part used to upgrade an 887va from 256 to 768, but since the part to upgrade from 256 to 512 is not the same as the part to upgrade from 512 to 768 I am not sure this is a safe guess.
