LAN connection issues with Leopard OS

I am the only machine on my LAN that has upgraded to Leopard. Since then
I cannot connect to some machines and the ones I can connect to are only
allowing me to connect to their home folders and do not give me the choice
to choose which drive I want to connect/ mount. Everyone else is on the
10.4.11 OS.

Have you checked for an update?

Wireless Lan connection issue with Linux clients

Hi
In a large Wireless Lan enviroment for a university, we have 3 WISM moduls attached on a 6k hw - Manged by ACS v6.0.181.0
We recently upgraded the software version of the controllers from 4.x to 7.0.98.0 - the Emergency Image version is 5.2.157.0
Since then, the students with Linux clients have massive connection issue - repeated connection lost in a short time period.
However the students with Windows clients have no problem at all.
The studends report, that their linux clients getting so much of some kind of unnecessary broadcast traffic which can not be handled by the NIC - and the NIC goes down - and this happens all 5-10 minutes.
Affected Linux clients are: Ubuntu v10.10 - also OpenSuse, Fedora and Arch-linx with latest OS version.
Any Idea how I could solve this problem?
Thanks in advance for your help

Hi Nicolas
Thanks for your reply. The broadcast forwarding is disabled on WLC's.
Pls find below the attached picture, which shows the captured broadcast traffic on a linux client (sent by a student to me).
I'm not sure, if its really only the broadcast traffic, which the linux clients can not handle.
From my point of view, it seems also to be that the linux clients are somehow disadvantaged among the other clients like windows or mac, if they all trying to get a wireless connection.
But the fact is only the linux clients are affected - and this happens to the linux clients only in our wireless infrastructure.
Windows or Mac clients have no such problem at all

Enis

I have Snow Leopard 10.6.8 on my MacBook. Constantly dropping internet connection or message "error connecting to the network" comes up. No wireless connectivity issues with windows 7 laptop or iphone.

I have a MacBook with Snow Leopard 10.6.8. The last few weeks it has been constantly dropping internet connection, and one of these messages appear on the page: "Safari cannot open this page because the server where this page is located isn't responding" or "Safari cannot open this page because you are not connected to the internet" comes up. I will check Wifi and I am connected. No wifi connectivity issues with iphone or windows 7 laptop, this doesn't happen with either of those devices. I have unplugged and reset router, cleared cache, still happening. Any ideas? Thanks in advance.

Connection issues with Safari 3

I'm having some connection issues with Safari 3.
When I connect wirelessly, Safari won't load any web pages. I go and use Firefox and everything is just peachy.
I've reset Safari, emptied the cache and whatnot. I went in and checked the permissions, everything checks out.
When I connect with Ethernet, there's nothing wrong, which is my dilemma.
Help would be greatly appreciated.

There are a number of posts in the Leopard forum from people with direct experience with upgrading from Panther to Leopard. Here is a relevant thread from there that should reassure you.:
http://discussions.apple.com/thread.jspa?threadID=1418714
Your system should be fine for Leopard, but you will probably need a current version of Photoshop if you don't already have it. See this download:
http://www.adobe.com/support/products/pdfs/leopardsupport.pdf
Also, Leopard doesn't run Classic (OS 9) apps.
One caveat - first make a bootable backup "clone" of your present system onto an external firewire drive so you can recover if anything goes wrong. You can use the "Restore" tab of Disk Utility to make such a clone, and there are also Panther-compatible versions of Carbon Copy Cloner (v 2.3) and SuperDuper (v 2.1.4), both excellent for this.
It's even possible to a create second Panther clone on a different external volume to create a "dual-boot" system, using that volume to continue to run old applications that you can't run with Leopard.

TSeries LAN connection issues across fibre link

I have some LAN connection issues when getting dhcp or even assigning static ip to T61 laptop. Doesn't get dhcp ip settings dynamic and if given staitc, can't ping any system on network nor can systems ping it. DHCP is at main site and this laptop is at remote site. Link between sites is fibre. All other systems at remote site where is laptop get their DHCP settings as normal. If I bring laptop from remote site to main site and plug in cable it gets DHCP normal but not at remote site, it doesnt get it, so i know the LAN adapter is good. What is wrong?, what across WAN link it preventing it? seeing that all other systems at remote site get their settings well. Thanks in advance.

I was able to resolve the problem. "The following CLI commands have been added to allow devices that do not understand the controller's proxy Address Resolution Protocol (ARP) response without a minimum packet size of 60 bytes to communicate with the controller: show advanced dot11-padding, config advanced dot11-padding enable"

TCP Connection Issues with OPC Server and GE Versamax

Hi there,
I have an installation of Lookout 6.0 coupled with the OPC Inductrial Automation servers. In my application, we are running two instances of the GE Versamaz Ethernet driver to communicate with two remote (over the internet) GE Fanuc Versamax PLCS.
Every few days, the two PLCs lose connectivity. It does not appear to be a LAN connectivity issue as I can still log into the PLCs using the GE software. To fix the issue, the Lookout software must be restarted.
Has this been seen by anybody else? This poses a significant problem as lookout is used to monitor the PLCS at sewage stations - each time the connections are lost we have to deploy technicians to the sites to ensure all is working.
-andrew

Hello Andrew,
When the connection is terminated are you getting any errors or alarms? If so what are they? Also you can try to replace the object that is connected to the PLC and make sure it has the correct settings. It may also be due intermittent networking issues, losing connection and not able to connect with the object again unless Lookout is restarted again. I have not heard about any such networking issues. The attached document can be used for reference.

RMM

BPC 4.2 connectivity issues with server

Hello All, I have a user that is experiencing connectivity issues with our server. This appears to be at a client level and I would like to know how to correct it. We are currently using BPC 4.2 (service pack 2).
The problem occurred when they had IE8 uninstalled and installed IE6 today. This morning he had no issues connecting to BPC w/ IE8, but lost that connection when IE6 was installed. When working through the connection wizard, the following errors appear.
Here are the pop-up error messages they are receiving:
"The server name, or IP address (srvbpmarl01) is unreachable now. Please check the following:
1. LAN connection or Internet connection is working properly.
2. Server name or IP address is invalid
Detailed Error Message: Internet connection is not available"
"The system cannot download information from server: SRVBPMARL01.
There may be a network or security issue.
Error message: Your LAN connection or Internet connection is not working properly.
Detailed error message: Internet connection is not available."
I can't help but feel this issue is a result of the IE 8/6 complications, but I do not know which actions to take next.
Thanks for any help you could provide!

I don't think the problem is related to IE.
It seems to be more a problem of configuration of IE.
I suggest to chec the follow:
1. Please make sure you are not using any proxy into connection of IE. Ot if you neede then make sure you will add your server into exceptions of proxy.
2. Try to connect with IE to server. use: http://nameofserver/osoft and also http://nameofserver.
If you received errors in both cases then it seems it is a problem with installaion of IE.
If you are able to connect and to display the default page for osoft then it must be a configuration problem.
I suppose MSDTC or Pivot table services is not correct.Try to use slow connection when you connect to server not High connection.

Connection issues with EA4500

I had bad connection issues with my mobile device, so i pressed reset on my EA4500 router, and now when i connect to my network, it gives my limited connection even though i have 5 bars of signal. Not sure what to do now...

Resetting the router will erase all the settings you configured on the router since the initial setup. You manually configure the router's wireless settings so your wireless devices can have internet access again.

Make sure to use a computer that is hardwired via Ethernet cable to the router.

CR2008 connectivity issue with BOE Universes(sap and non sap universes)

Hi Experts !!
Recently we tried to build/connect to a Universe in Crystal Reports2008 via 'Make a new connection tab'.
The universes are of SAP BW or non SAP Lying in BOE Servers and we are trying to build reports on them by conncting/utilizing the universes as a database for Crystal Reporting.
Our issue is most of the time we are not able to connect to the Universes and the connectivity blows out by some 'communication Error' thing initially.
While at some other points in time, the connectivity takes us to the Universe and we are able to select few characteristics and key figures from the Universe but the moment we go futher and try to run by pressing 'OK' button it blows out and say' LOGON FAILED'.
Apparantly, it is an connectivity issue with BOE server and from the different blogs it looks like it is a known issue for long.
The proposed issue resolution were like either CR2008 should be SP2 with BOE SP3 or there should be some additional .dll files defined in the paths in case of MSSQL database. None of this applies to us as we are on CR2008 with SP3 and going back to SP2 is probably not a viable option for us, and we are using Oracle as underlying database in this specific case.( i would like to tell you here that we are able to connect to Oracle Database directly though).
We have raised a message with SAP and was just wondering if we do have some solution/workaround already available to this known issue in place please?
Thanks&Regards.

Hi Amit,
Moved to Universe Forum.
If you have a case logged then no point posting here also, this is a public site and not a case management tool.
Once you do get the solution from your case please post it here also to help others if they have the same problem.

Additional things to try.
Try this first. Turn Off your iPad. Then turn Off (disconnect power cord) the wireless router & then back On. Now boot your iPad. Hopefully it will see the WiFi.
Change the channel on your wireless router. Instructions at http://macintoshhowto.com/advanced/how-to-get-a-good-range-on-your-wireless-netw ork.html
Another thing to try - Go into your router security settings and change from WEP to WPA with AES.

SFTP connection issue with Dreamweaver 2014

I have a very weird SFTP connection issue with Dreamweaver CC (2014). I am on a Mac running 10.9.4 and have no problem connecting to my server through SFTP with Dreamweaver CS 6. However, using the exact same settings on CC (2014), I get the following error: "An FTP error occurred - cannot make connection to host. Your login or password is incorrect. Please check your connection information".
I am truly at a loss here. Command line connection works without problems.
Any thoughts?

Hi there,
Try after rebooting your system or in a different user account on MAC.
Is there any limit with number of login sessions with your SFTP?
Could you check with Filezila or similar FTP client and connect to your site, see if you get any error there?
Thanks.

Anyone else having repeated wifi connectivity issues with the OSX version 10.8.5?

I just updated the software on my iMac to OS X version 10.8.5. Now I am having repeated connectivity issues with the wifi in my house. This is the only device that is having these issues. My phone, ipad and tv are not having any problems at all.
It happened immediately following the update. I was sending emails and browsing before the update without a problem.
from apple:

I had a message like that last week - only it asked what browser I would be using - I just quit safari - purges caches etc - and at that time noticed I was getting RSS feeds through PUBSUB - tracking them down to the top sites view I never use - I deleted all of the top sites (most of which I don't go into so it must have been a preset) that included MSN and Google - I don't use google so that was pointless. (deleting a top site means you are blocking it from that page) Have not had the message since so it must have had something to do with top sites activity.
Just a note: Did see somewhere probably BBC tech - that Google was going to stop supporting older web browsers.

Connectivity Issue with FIOS

Hey all,
Has anyone in the Tampa, FL 33629 area had connectivity issues with their FIOS services? My current setup is a Motorola modem that is plugged into a D-Link Router that was provided by VZ. At the D-Link located outside of the house the connectivity light is flashing red and according to the legend it indicates that it has passed the test but is having communication issues. This has been occurring over the past few weeks. The first call to customer service, after diagnostics where run and the outside unit was unplugged and battery were removed as well as all modems and routers being reset, the service rep scheduled a tech to come out. The next morning it seemed like everything was back to normal. Since then we have had intermittent service and I am currently without phone and Internet access (bundled the phone, TV, and Internet) for a couple of days due to their internal service report and dispatching system being unavailable. Just curious if anyone else has encounter this issue.
Thanks,
JB
