View 2 RepliesI manage the network of a small (120 users) network spread out over 5 sites within a 10 mile radius (for normal ops- extended ops can expand to include other cities).I think I'd call that a Campus LAN, perhaps it's just a really small MAN (for normal ops)...I am starting my CCENT/CCNA track so this may be blazingly obvious to some of you- but I'm sure to learn something either way...Every now and again we have to go find "hostname "X"" for an update that won't roll out by way of our (Server Sr SysAdmin's) tools, so we actually have to put hands on it. Unfortunately the prior admins didn't document the inventory to such a level that we know "laptop_015" is in the building down by the college.
I DO have documentation on my equipment (I'm the Network Sr SysAdmin) that I have rolled together over the last 9 months being here...I have a Cisco 5520 ASA, and use ASDM to manage it. What would be extremely handy would be the ability to put a query in the system to report back what switch a given hostname is plugged intoBetter yet, if it could tell me switch and switchport.I imagine this would be simple if I had the MAC address- there's got to be a way to grep the switches for a given MAC- but not sure if it'll work in a similar fashion for ARP lookups.
Windows 2003 R2 Server machine cannot be pinged, not XP? I'm running a highly modified version of Windows 2003 R2 to make use of an old PC. It connects beautifully to a Verizon router (I can browse the Internet), but I can't figure out how to share folders on my network. I have a Macbook and Win7 machine and both cannot see this old PC on the network. I have tried to ping the old PC from my Win7 machine, and it will only timeout. Below is some relevant output from the old PC

View 3 Replies View RelatedI have a strange error on my home network that I cannot find a solution to.I have an Huawei SmartAX MT882 from TalkTalk acting as a modem connected to a D-Link DSL-G624T acting as a router/switch. Connected to the D-Link I have a Windows 7 Pro machine (64-bit, SP1) and an XP (home i think) machine (sp 2 i think).The SmartAX modem is set up to perform DHCP and DNS relaying and the D-Link has DHCP turned off and DNS relay turned off.The Win7 machine can access the network, get an IP address and access the internet without problems, regardless as to the status of the XP machine.The XP machine can access the network, get an IP address and access the internet with no problems ONLY of the win7 is powered up. When the win7 machine is off, the XP machine seems to drop about 25% of the ping packets between it and the D-Link router and has no internet access (because of this i assume). [code]

View 1 Replies View RelatedNew Win-7 machine set up. I used the printer set-up wizard to install a networked printer in the new machine with absolutely no problem. Proved it would print from that machine.Now, I get a call informing me that her old XP machine, which had been printing to the network printer with no problems, will no longer print.Documents go into the print queue, but they don't get printed.No error messages show up.I did some messing around via remote access, and finally removed the printer with the intention of reinstalling it.Scanning for network printers turned up several redundant instances of the same printer with different names. Some are identified as "invalid" some a "access denied". Bottom line. I can't get any of the selections to install.On the Win-7 machine I did find a window that indicated that the printer is designated as being shared, but I didn't explicitly set it for sharing when I installed it. Also, I somehow got to a window that told me that for printers that were to be shared with other versions of windows I could optionally install drivers to support such machines. Didn't have the driver disk handy and took the window down. Now I can't even find it again.I need sorting this all out.Part of the problem is that out there in "network land" there are redundant remnants of previous installations that are being remembered inappropriately.

I have a network problem. My windows 7 machine is not detecting win xp machine whereas win xp machine is detecting win 7 machine. They are in the same workgroup named Home. And the networking system is set to work. I have left the homegroup I was previously in. I enabled file sharing for devices that use 40 bit and 50 bit encryption. On XP I have enabled NetBios over TCP/IP. File sharing is enabled on both computers. I think it's something obvious as both instalations on different computers are really fresh and both windows haven't been tampered with.

View 1 Replies View RelatedI would like to get using of course SNMP, list of client IPs connected to VLAN in Cisco Catalyst 3600.So far, I have pseudo-algorithm made by me which obtains those IP addresses, but I am not sure if this is done in right way :
1) Receive all IP addresses from Catalyst using oid 1.3.6.1.2.1.4.20.1.2. I get something like :
IP-MIB::ipAdEntIfIndex.10.10.2.1 = INTEGER: 152
IP-MIB::ipAdEntIfIndex.10.10.2.251 = INTEGER: 152
IP-MIB::ipAdEntIfIndex.10.10.3.251 = INTEGER: 151 and so on.
2) Get ifIndex of VLAN (oid 1.3.6.1.2.1.4.20.1.2.10.10.2.1.<IP_ADDRESS>) for particular IP address from above list :
IP-MIB::ipAdEntIfIndex.10.10.2.1 = INTEGER: 152
IP-MIB::ipAdEntIfIndex.10.10.2.251 = INTEGER: 152
IP-MIB::ipAdEntIfIndex.10.10.3.251 = INTEGER: 151
3) Get VLAN name (oid 1.3.6.1.4.1.9.9.46.1.3.1.1.4.1.<IF_INDEX>) If_index is borrowed from list above :
IP-MIB::ipAdEntNetMask.152 = No Such Instance currently exists at this OID
IP-MIB::ipAdEntNetMask.151 = No Such Instance currently exists at this OID
In the third step I have this problem, that instance can not be found in OID. It is weird, because for about forty IP addresses i can find about their 10 VLAN names to which they are connected.

View 1 Replies View RelatedI bought a Sonos multiroom-system, and connected the first player to my E2000 router through Ethernet. It then gets a dynamic address through DHCP, I can see the Sonos within the network when looking in the admin tool of the router.When I start the Sonos controller software on my PC (XP), the software can not find the Sonos when my PC is connected through Wifi.As soon as I connect PC to the router with ethernet cable the Sonos is found immediately and can be initialised. After that, I can disconnect the cable and control the Sonos wirelessly. (as long as I don't close down the controller software for too long)
From what I understood from the sonos.com website, the Sonos sends an UPnP multicast signal on port for SSDP on port 1900 for initial connection. Further communications port are described below.Somehow, this multicast package seems not to be transferred into the wireless LAN, only into the wired LAN. Do I have to open some ports, filter some ports?Forward them?
