About network with controller and light ap

in my company ,we have controller 4402,and some 1240 light ap,sametimes,notes,and some client with xp or vista.now when the client with xp,the sametime can ok;but notes fail;when client with vista ,notes,sametimes could not run.

Hi,
*Nov 6 15:32:26.611: %CAPWAP-3-ERRORLOG: Retransmission count for packet exceeded max(CAPWAP_WTP_EVENT_REQUEST
Looks like it is loosing the heartbeat with the WLC.Just try to increase that value if that helps.
Is proper QOS in place to prioritize Capwap packets.

Unable to connect to network with Safari and Software Update

A user I support has encountered a problem with networking. He is unable to connect to the network with Safari and Software Update, but IS able to connect and surf with Foxfire and some other programs. Another unusual symptom is that he actually can connect to one web site (which is in his Bookmarks Bar) with Safari, but can't connect to anything else. He's also unable to navigate off of that one site he connects to. When he runs Network Diagnostics, he gets all green lights (no problems). He has fixed permissions, deleted Safari Cache and .plist, rebooted - not fixed yet. He's using 10.4.8 on a PowerPC G4. Any ideas appreciated (this is the wierdest I've seen in a while!).

Here's what he did. After reading your post, he created another location in his network preferences, entering EXACTLY the same info that was in his old location (he even used the old DNS addresses), except using a new location name. Then he chose the new location and "everything worked". It's one of life's great mysteries. Thanks for your help - it is appreciated.

Full mesh VPN solution for on MPLS network with PE and CPEs

Hi,
We are trying to evaluate some best solution for Hub-Spoke mesh vpn solution in a MPLS network. The VPN hub router will be in PE router and all the VPN spoke will be in CPE.
Can someone please let us know what will be the best vpn solution, we understands that there will be some technical limitations going with GETVPN but still we did counld find any documenation for possiblity of using DMVPN.
How about the recent flexvpn, can fex-vpn work on this requirement, where can i get a design/configuration document.?
thanks in advance.

Hello,
GetVPN is intended for (ANY-to-ANY) type of VPN communication, over an MPLS network with Hub and Spoke Topology, your best Option is to look for Cisco (DMVPN) implementation where this type of VPN is primarily designed for Hub & Spoke.

Mohamed

P1006 - networked with XP and VIsta-64 not printing more than 2 pages

Hello - I have a dilemma with my HP P1006. I have the printer directly plugged in (USB) with my XP (32bit) PC. I have a Vista-64 PC networked with it. Both (XP-32 and Vista-64) are plugged in directly to the router (not wireless). My question is why can I not print more than two pages at a time with items opened on the Vista-64 PC? I CAN print more than two pages with items opened in the XP-32.
Things I've done:
1 - uninstalled everything & reinstalled the latest drivers for the XP-32.
2 - marked the printer as "sharing" on the XP-32.
3 - confirmed the printer is marked "enable bidirectional sharing" under the printer properties on the XP-32 PC.
Things I perplexed about:
1 - why won't items (docs, webpages, etc.) print more than two pages at a time from the Vista-64 PC?
2 - is there any reason that I should download a driver for the Vista-64 OS? If so, which PC do I download it to?
3 - I have another printer (Lexmark inkjet) connected in the same way (except it is a serial port not USB) and it can print more than two pages of a document at one time with no problem from either the XP-32 or Vista-64 PC? Why?
Any thoughts on this situation? Any suggestions are greatly appreciate.
Thank you - Jane.

Hi!
I just get a system message at teh bottom of teh screen saying "output cannot be issued " and it remains on teh same screen . I goto t-code va23 and enter my quotation number and on the top I select sales document ...issue output and select my output type and print preview or prnit , it comes out of that screen into the first screen and at the bottom gives msg "Output cannot be issued". I beleiev its not allowing the smartform to display when there are more than 2 pages , because I tried it with a contact which has 2 pages and it shows output but when I try with the one having more items i.e more than 2 pages it comes out of it . Its a smartform issue and something in the smartform is causing problem I beleive.
Thanks

[SOLVED] Question about network setup static and dynamic

I am trying to set up an Arch install on my other pc. I have used Ubuntu and then Linux Mint for a year+ and Arch has always intrigued me so I am attempting to install it now. I do consider myself a pretty advanced computer user/programmer but computer networking has always confused me a little. I'm not quite understanding whether I setup my network with a static or dynamic ip. This is what I know
I have a static ip assigned to me by my ISP but I do have a router so it assigns me a different internal ip. Does that make my ip dynamic?
Last edited by c26zwj (2013-03-14 18:24:35)

If your ISP assigns a static IP then your IP in the internet is static. If you have a different internal IP then your router is running a DHCP server and performing network address translation. Your IP on the LAN is dynamic (unless you configure your router to assign static IPs, which can be useful if you want to forward ports to a specific computer). You most likely want to use DHCP to obtain a dynamic internal IP when you connect. The external IP is beyond your control (it is managed by the ISP and assigned to the router) so you do not need to worry about it.

Setting up network with newer and older AirPort Extremes

Okay, I thought this was going to be so simple. I have a newer (like a year old - square) Airport Extreme that I have three computers wirelessly hooked up to in the house. Great... so now, I want to hook up the old iMac in my son's room that doesn't have a wireless card to the network. It is too far away to use the ethernet cable into the back of my newer Airport Extreme station so I figured I'd dust off the old saucer type base station, plug the ethernet cable into that in my son's room and then just easily get the old base station to network with the newer one wirelessly.
Not so easy. The newer one has no reference how to make a network with other base stations whatsoever and the old book describes how to with the Airport Admin Utility which is not available to the newer version, just Airport Utility and it does not have the WDA options listed. I tried to extend the network and then Doh! The whole network disappeared.
Is this a compatibility issue with the older and newer base stations? Would it just be easier to put in a wireless card to my very old iMac, if that's even possible? Has anyone successfully networked an old and new base station together? If so how?
Thanks!

Welcome to the discussions!
When you have an older "g" device (the flying saucer) and a newer "n" device (the square one) in order for them to communicate using wireless only, you must configure both of them in what is known as WDS configuration.
This is a quite tricky setup for most users. The best set of instructions that I've seen for this comes from expert user Tesserax in this thread:
http://discussions.apple.com/thread.jspa?threadID=2355832&tstart=0
If you elect to try this type of setup, you will probably need to hold down the option key on your Mac while you click on the Wireless Mode selection box to get the WDS option to appear. (My guess here is that Apple "hides" it because it slows down the network substantially). But, it's the only way to do what you want to accomplish with and old and new device.
Other options would include the wireless card you mentioned for the iMac. Even better might be a pair of ethernet powerline adapters. One adapter goes near the AirPort Extreme and the other near the iMac. The AC wiring in your home transmits the ethernet signal of the powerline. Works great, almost no configuration required and better than wireless in many cases.

Using MAP on networks with AIX and Oracle

Im new to MAP. We have an environment with Windows and AIX hosts which i want to use MAP on. I see plenty of references to MAP being compatable with Linux and even HP-UX. But will it also discover AIX hosts too? In particular, Oracle databases
on AIX? Thanks!!

Some distros of Linux and HP-UX for UNIX are what is supported, but it may be possible for MAP to inventory AIX, but no guarantees. For Oracle, when MAP inventories a Linux/UNIX machine, it queries for the RPM and DPKG installations then looks for ‘Oracle’
in the vendor attribute. Any application that is not listed in either of those queries is not discovered by MAP.
Therefore, if Oracle was installed by some other means then it is unlikely to be discovered through this method. Admittedly, I have almost no knowledge of how these services work and if they register software or something else.

Problems opening and saving PNG over network with CS2 and CS3

using os10.4.11
photoshop CS2 or CS3
I've recently tried to save images in PNG format, small (no more than a couple hundred kilobytes) and found that whenever I tried to save to the server it would hang photoshop and require a force-quit. Saving the same file to the desktop works fine. Copying said file to the network and then trying to open that PNG from the server results in a photoshop hang, while opening that same file from the desktop works fine. I know all about the fact that Adobe doesn't support working over a server, but that's never been an issue at my workplace in all the years I've worked with (never had problems saving/opening any format, no corrupted files ever). If I try to open that same PNG from the server with CS2, same result. If I try to open it over the server using Photoshop CS, or version 7, however, it opens just fine. If I copy the Photoshop CS version of the PNG plugin and replace the PNG plugin installed with CS3 by default, then it seems to work and I can now open and save PNGs anywhere with no problems. Has anyone else had this problem? I can see that the file size of the PNG plugin has changed version to version, so something about it has changed. It seems as though there is something defective about the ones installed with CS2/3, and just copying the CS version into my CS3 folder clears up the problem.
Also, the problem is not limited to my computer. Other macs that try to open PNG files from the server using CS3 or 2 also hang.

Yes, we're a prepress company moving around probably a few dozen gb of data per day, saving PSD, TIFF, EPS, JPEG, all kinds of formats. It's the first time I've had a client requesting PNG files, and so the issue has come to light. This is the first time I've ever seen any kind of issue opening/saving across our network in 8 years. (the only time I've ever seen a corrupt file was a 1.6gb image that didn't copy correctly, and that wasn't a photoshop-related corruption, but an OS drag/copy of the file)
I'm not sure if I'll be able to find someone with OS 10.5 or some other version to see if they cause problems. If anyone else reading this who works over a network can test a PNG open/save over their network and list their OS and Photoshop version it may help. I'm going to see if I can find some other computers to try it out on in the meantime and mention it to IT.

Setting up home network with new and old Macs and 1GBps internet connection

I have a 1 GBps internet connection and want to take advantage of it. I have three 802.11ac capable Apple products - a Macbook Air, Macbook Pro and Imac. The signal currently runs from an Aris modem into a Netgear router that maxes out at 100mbps. My Apple Extreme (not the new one with 802.11ac) is connected to the Netgear , so choked at 100mbps. Everything runs off Wifi. I have run speedtests on all my computers and nothing runs over 50mbps in the current setup. I also run some home security stuff off "DDNS" that does not work with Apple products (thus the Netgear router) so I need to consider that too. I use two 802.11n extenders around the house. I am being told I cannot use the newer 802.11ac Extemes because it would not work with the DDNS Security stuff. What do I do to maximize speeds from Wifi and keep the DDNS stuff?

What do I do to maximize speeds from Wifi and keep the DDNS stuff?
For maximum Wi-Fi speeds only, use all 802.11ac devices ... both wireless routers & wireless clients. For full DDNS support, only use routers that support this feature.
For maximum overall bandwidth Internet-to-network client, use routers that support 1Gbps WAN-to-LAN & LAN-to-WAN interfaces. There are not many on the market currently that supports this. Also these routers should provide Gigabit Ethernet on both the WAN & LAN sides.
To get an idea of what's available, please check out the SmallNetBuilder's to compare routers.

Expanding network with TC and access question

Hi All
I need to look at a new external hard disk since my current 160gb is just getting too full, so I figured it might be time to get a Time Capsule, probably the 1tb.
I've got two questions before I do..
1. Currently I have Sky Broadband. I've read a lot of people saying that it is not possible to make TC part of the existing network through wifi so have to connect. If thats the case I'm probably better off with standard network drive. Has anyone managed to do this yet? Im wondering if the reviews I've read are just that people couldn't work it out?
2. I assume this is the case, but can I access the HD as a standard network drive for general storage? Is it possible to define how much space Time Machine can use say 500gb, and leave 500gb for general usage?
Many thanks for any answers

The issue I have is that Sky Broadband forces you to use their router for broadband access. They hide the user name and password on a chip so it is not possible to configure.
Besides my phone is downstairs and my printer is upstairs in the little office. My plan was to have TC upstairs, with printer connected. Have both the TC and Sky Broadband router all part of the same network.
Then I'd use a cable to do the first backup and use wireless for incremental backups.
It does look as though I can't use this configuration. But its a bit strange, I thought it was part of standard wireless networks that you could use access points to extend them. I assume then that apple are not using all of the standards?
If that is the case, I'd have to plug it into my router as a wired option, in which case any external HD with a network interface will do half the job I need.
I'm just trying to find out if anyone has managed to get it extended from sky (or other router). Note I can change my sky router settings so in theory could change the sky one to use the apple settings, does that make a difference? Anyone had success that way?

Speeds in gigabit / 100 mbit network with TC and other devices

My network has a Netgear WGT-624, that serves as DHCP server, NAT and Internet connection.
We have two mac minis (gigabit network), a G4 (standard Ethernet), some PC laptops (running 802.11b/g) and some laser printers and AIOs that runs 100 mbit Ethernet.
There's also an ancient Netgear hub, that I will replace with a D-link gigabit switch. The switch will serve the TC, a printer and the G4.
From what I understand, devices with gigabit will be able to communicate with other gigabit devices on the same network. But, will it work even if the TC is NOT used as the primary AP, but set in brigded mode? There's quite a difference in backup speed if the TC and the minis could talk to each other with gigabit.

Help setting up small home network with PC and an imac!!!?

I have an imac in my room, and my mother has a JP PC in her room across the house. We have a router and modem on her computer(I connect to the internet through the router signal)
I just recently bought a new printer. It is a wifi printer. I was told by a friend that I need to setup a small netowrk so all the computers/printers in the house can talk to one another. Because right now my printer is installed and connected to the router signal (but my computer does not reconize it to print....)
I started a small network on my moms PC...but when I can't make a network CD like it tells me to because my computer is a Mac....how do I continue to setup this network?Can I set it up first on my mac as well???PLEASE HELP! I want to use my printer!

You can just connect the WRT54G wireless router’s LAN port to BEFSR41 router’s LAN port by using a network cable as specified in this configuring wireless router as access point article, after that can connect other computers to that wireless router with or without cable. Finally do more test to check the performance. Hope it helps.

Networking with PCs and Viruses

I'm sure this has been asked before, but I couldn't locate a thread for it.
If I network and view PC files on my Mac, does that make my Mac vulnerable for PC based viruses?

No, PC viruses will not run on Macs, with the exception of a very small number of macro viruses that affect MS Office files (Office apps will warn you if you attempt to open a file with embedded macros, and not all macros are viruses, so some files are supposed to have them - just be sure they are from a trusted source if you see the warning pop up).
You do run the risk of being a carrier - passing a PC virus on to another PC user - if you forward infected files.
You can use the freeware ClamXav to scan your Mac, if you are so inclined.
Hope this helps...

Networking with macs and pcs mixed

Is it possible for me to:
1. take an old PC with a huge hard drive in, wipe it clean and install Leopard onto it to use as a simple server?
2. network it for a home office of 4 computers (2 macs, 2 pcs)?
I've never done networking before-is this possible?
Thanks

1. take an old PC with a huge hard drive in, wipe it clean and install Leopard onto it to use as a simple server?
If by "PC" you mean non-Apple hardware, no. Mac OS X only runs on Apple's systems.
2. network it for a home office of 4 computers (2 macs, 2 pcs)?
If you run Leopard on a Mac, yes, you can have up to ten systems connect to it, both Windows systems and Macs.
