I am trying to find a way to find the netid and hostid of any given ip address, given any ip address, I know the left side the IP address is the netid and the right side of the ip address is the host id but I am pretty sure there is more to it than that.

Issue: When I attempt to save the changes I made to the DHCP reservation list I get an error window that reads:

I have a problem with LMS 4.2 user tracking.When I generate a report on all my network all mac address are ok but there is no Hostname/Ip address in the result, except for 2 equipments.the only difference between these 2 equipements and the rest of the network is that they are connected on a not routed vlan. All the other phones, computers are connected on a routed vlan.I have a Nexus 5k as core and 2960 as access. Routing between vlans is done with the NexusMy DNS server is ok and reachable.

In the end host tabe we see only the MAC-Addresses of the host connected to this switch. No IP-Address. The corresponding IP-Addresses are in the ARP-Table of this non Cisco Layer-3 Device.

View 1 Replies View RelatedI replaced my old wireless router with a Cisco Linksys E4200, running firmware version 1.0.02 build 13 May 24, 2011. About once a minute the router sends an unsolicited DNS message to the IPV4 multicast address 01:00:5e:00:00:fb with a destination IP address of 224.0.0.251. The unsolicited message is a DNS response with source port 32784, transaction ID 0, flags 0x8400 (standard query response, no error), questions 0, answer RRs 2, authority RRs 0 and additional RRs 1. The two answers both relate to the router itself: one has Name Cisco18738.local, type A (host address), class 1 (IN), cache flush true, time to live 1 minute, data length 4, and the address of the router. The other is the reverse of the same address. The additional record is for Cisco18738.local, type NSEC, class IN, cache flush true, time to live 1 minute, data length 5, next domain name Cisco18738.local, RR type A (host address).
When my desktop computer receives these messages it logs an error, for example: "Jun 23 07:39:22 sauterws02 avahi-daemon[1067]: Received response from host 10.146.9.1 with invalid source port 32784 on interface 'eth0.0'" The 10.146.9.1 is the router's IP address. I also see these messages on the wireless link from my laptop.I suppose the E4200 is generating these DNS messages in a misguided attempt to make sure there is no old information about its name. Is there a way to turn them off? If not, is there a way to report this to Cisco as a bug?
The old syntax that I am much more familiar with has been deprecated. On older IOS it would have been something like static (inside,outside) tcp 209.114.146.122 14033 192.168.30.69 1433 netmask 255.255.255.255 Plus an extended ACL to allow the traffic.I am trying to create a Static PAT to allow a host address to access our Network through an ASA. I have external address 209.114.146.122 that I want to hit the external interface on an obscure port (say 14033) and translate that traffic to an internal host address on port 1433.

View 1 Replies View RelatedI am learning to write ACL's along with a billion other Cisco things. The internet is not clear on how to do this exactly. At least in my research.
I have two host on the same subnet and I want to block all except RDP TCP port 3389 from one host to another.
I want to apply that Access-group to a switchport interface on my 3750 that belongs to the computer I want to protect from the other.
Host A: 10.1.1.10/24 -- I need to block all TCP and UDP traffic except for port 3389tcp
Host B: 10.1.1.60/24 -- I need to allow only TCP port 3389 from Host A to this one.
This is on the same switch so I can use an extended ACL like 101 or whatever.
This is almost starting to make sense to me but im still weak on extended ACL. I got basics down pretty well.

I downloaded the HOSTS file from winhelp2002.mvps.org, hoping it would better my security. However, now some pictures that used to show either show the "Internet Explorer cannot display the webpage." or just have the X box thing. I'm guessing this problem results from the new HOSTS file. What should I do? Should I revert to my old file? If so, then how can I do this?
View 4 Replies View RelatedBasically, I am swapping my Atom/ION nettop (that I use as a file server, game server, torrent server etc. etc.) for one that has no fans and no mechanical HDD. I control it primarily via RDP, so I don't need to plug a keyboard or display into the nettop itself.
The new one I'm getting should be a step up due to the whole no moving parts thing, as well as the much faster CPU. But Intel, in their infinite wisdom, have not provided (and don't plan on providing) a 64bit graphics driver for the GMA 3650.
If I were to install 64bit Windows on this new machine without installing a driver for the graphics, would I have any issues using RDP? I'm not sure if the visuals are generated on the host or the client and whether it would matter either way.

View 5 Replies View RelatedI have an old ASA 5505, and I'm having some trouble with Nat Hairpinning. I've done this with other firewalls before and I am having no luck now. I have an internal address that I wish to forward from an external address- so if someone goes to 123.456.789.012:3456 then it will forward to 192.168.1.244:92 (All numbers are arbitrary here- only for illustration). I have and Access Rule and NAT and PAT set up so that I can get in if I originate from outside the LAN. What I am trying to do is to have this work from inside the LAN as well- so that if I am at my desk, and I connect a device and type in 123.456.789.012:3456, it will deliver the content at 192.168.1.244:92. The problem I am having is that it just isn't working, and I cannot figure out why- When I started here, there was an address configured to work this way, and it still works- I just cannot find what is different between what I am doing and what the person who configured it did.
