How To Traceroute Show Two Different Names For Same IP 365 AddressMay 22, 2013
Here are two traceroutes both to 22.214.171.124. One results in the name ns1.hosting 365.ie and the other in the name mail.hosting365.ie. Why the difference? [code]

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 can find ip address of any website from domains by using simple command [URL] in command prompt.I wonder how I can find the domain names from ip addresses.For e.g. I would like to know the domain names of ip - 188.8.131.52View 7 Replies View Related
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.View 2 Replies View Related

How come the 2600 series IOS has the show mac-address command but it does not display anything? you need to use show arp? is this for when you use one of those network modules that is a switch?View 2 Replies View Related

We got a question about our WLC 5508 single controller deployment with 14 access points without a VLAN configuration.
When our clients connect to the wifi, we cannot see any ip address of them in the client details page. It shows everytime the ip address 0.0.0.0. The clients are configured with a static ip.

We all know that MS traceroute and *nix traceroute work a bit differently. *nix works by sending UDP packets with low ttls to random high UDP ports.
Of course this creates a problem when trying to create an ip6tables rule where I want to allow traceroute. Anyone got something clean that will make this work? This is an example of current drops in my firewall log:
I need to allow traceroute traffic through ASA running version 8.0.2.This traffic is natted. what configuration is required on ASA to allow this natted traceroute traffic.Traffic is coming from inside and going outside.Also can we capture this traceroute traffic on asa using capture feature.View 12 Replies View Related
I have been searching to find out how to allow traceroute from an inside host to an outside IP address. I have found a few articles for IOS versions prior to 8.4 but nothing for 8.4. I can traceroute from the CLI of the 5510 just fine but from a windows host on the inside network all I get is Request timed outView 1 Replies View Related
I'm working as a network engineer for a service provider, and we had just gone through a pretty large scale upgrade throughout our network and service.But not long after the upgrade (or maybe ever since the upgrade, we can't confirm this because we probably missed it out due to many other links to be tested), we met a peculiar problem.Everything seems to be running fine most of the time, but there has been some weird 'ghost-like' activity which have been causing inconsistent network disruptions. At times, certain portions of the network can't communicate with other subnets.And most obviously is the problem with a continuous ping and a traceroute simultaneously. Ping is usually normal, but until a traceroute is attempted, it times out at the same time as tracert fails to obtain the route.Besides, performing a ping from the 2nd closest hop address, 10.250.253.251, which is a cisco layer 3 switch also has problems, the results shown are as belowType escape sequence to abort[CODE]View 1 Replies View Related
I've got an annoying problem with my ASA 5520.I have traffic going from the inside interface (security level 100) to the outside interface (security level 0) with a global PAT applied to the outside interface address for all inside traffic - and I can't seem to traceroute through the firewall.The ruleset is simple - basically, allow any IP from inside to outside. The NAT is simple - PAT all traffic unless exempted to the IP address of the outside interface.If I do the trace from my internet edge router it works fine - so I know it's not soemthing my uplinks are filtering - but if I do it through the firewall, I get perfect responses until the hop where it hits the firewall interface - then nothing.Is there something I am missing that I need to do to allow traceroute to just work with all the rest of the traffic?View 2 Replies View Related
My setup is :
Source--- Router 1 ( ip 184.108.40.206) --ACE---router---cloud---customer---router--destination( ip 220.127.116.11).
Traceroute from client to destination shows the following:
traceroute to 18.104.22.168 (22.214.171.124), 30 hops max, 40 byte packets
1 126.96.36.199 (188.8.131.52) 1.10 ms 1.78 ms
2 184.108.40.206 (220.127.116.11) 1.01 ms 1.97 ms 2.511 ms
3 18.104.22.168 (22.214.171.124) 2.01 ms * 126.96.36.199 (188.8.131.52) 2.330 ms
So on this, the destination is 184.108.40.206.The first hop is the default gateway, which is 220.127.116.11.After that, the next step is the Cisco ACE.After that there are several hops to the destination.Looks like for some reason the Cisco ACE is not recording his ip.( For any destination traceroute result is the saame.ICMP is allowed in the access list and also ther is ICMP inspect in my config. access-list ICMP line 10 extended permit icmp any
class-map type management match-any abc
201 match protocol ssh source-address X.X.0.0 x.x.0.0
class-map match-all ICMP_allow
2 match access-list ICMP
Version running on ACE is Version A2(3.3)
there is an issue with tracroute from ASA 5505 with 9.0(2) - here is the running configuration [code] with this running configuration - from the LAN tracerouet to public IP, it is working fine. but once I traceroute from the LAN 192.168.225.x to the corporate networks via the IPSec l2l tunnel - it does not show any hop at all - even the inside interface of the ASA does not show in the traceroute.View 4 Replies View Related
We have a ASA 5505 and a 5510, that we are using site to site..I need to traceroute from the 5505-5510.. From the outside interfaces.. Don't want to do this through the site-to-site.I have temporarily added a few acl on the outside interfaces..
-access-list outside_in extended permit icmp any any unreachable
-access-list outside_in extended permit icmp any any time-exceeded
-access-list outside_in extended permit icmp any any echo-reply
when i traceroute it only goes one hop.. Maybe thats the way it suppose to be? I need to know all the hops between the outside interfaces on the 5505 to the outside interface on the 5510.
I've read through netpro and found everyone points to this doc.
However that still doesnt allow traceroute through for us. We still see syslogs with deny's on high level random UDP ports to different Internet destinations.
I have configured a vlan interface on a 3750 switch. there is aprox 4Mb active traffic flowing through the interface, but when I do a "show interface vlan (vlanid)" the output show zero bits in and zero bits out. Its a typical L3 config with one IP on the vllan interface acting as the gateway for the VLAN devices. Is this a normal behaviur ? and if so is there any way to get the traffic in/out stats. The end PC/devices are connected to this switch via an L2 TRUNK and I dont have access to the L2 switch on which the actual devices connect. so cant get the real time stats of those interfaces.View 2 Replies View Related

=>Routing Protocol in Question EIGRP.
=>Two equal metric routes for destination A(through R1 and R2-SVIs on two upstream 6500s)
Traceroute Output, is the output that alternates between 1.1=>10.1=>1.1 normal granted the two routes are "equal metric routes for the same routing procotol in use" or is that "round robin behavior" indicative of a routing problem?
Why does the sx300 series only displays ping and traceroute results in 20ms intervals (see below)? The example in the CLI manual shows "regular" results. These 20ms intervals are not useful for troubleshooting. This is version 18.104.22.168 on an sf300-24. [code]View 2 Replies View Related
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.View 7 Replies View Related

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?View 1 Replies View Related

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?View 1 Replies View Related

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 "email@example.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 126.96.36.199 , with a pair of WLC 4402 controllers running 188.8.131.52 . Our WPA2 Enterprise auth uses TTLS/PAP, with the SecureW2 supplicant for Windows.
