IChat over Uni network

I use my laptop the most over my university wireless network. Now, I have seen plenty of people using MSN Messenger etc. on their own laptops and on the same network but I can not get iChat or Mac Messenger to connect. The only think that does connect for me is Skype.
Can anyone suggest how to overcome this?

You should be able to get iChat to at least login if you go to iChat > Preferences > Accounts > Server Settings and change the port to 443
MSN and Skype try other ports below the 1024 threshold (where ports above need to be open)
Changing the port in iChat should get you to at least Text chat.
As the A/V ports iChat uses can not be changed it is unlikely you can Video or Audio chat without getting the IT guys to open the ports.

Problem with iChat over wireless network

iChat with AIM account has always worked fine, but from the moment I installed a netgear router over a wireless network it enters a loop of disconnection/connection until I get the message "you have been connecting and disconneting too frequently". Someone else ? What to do ?

Can you marked this thread as Finished then please ?

IChat over slow network

Hello,
I'm not really good with network stuff, so I know very little about my problem here. I'm working on an offshore drilling rig and they've recently set up a wi-fi system for personal use. It's very slow and governed by the nanny Websense.
I know some people are able to use their IM chats and I was wondering if there is a way to set up my iChat to work on such a slow network. It won't connect at all when I'm here. I know I won't be able to video or audio chat, but I should at least be able to text chat, shouldn't I? Or is it possible that Websense has blocked certain IM's and not others?
Any suggestions would be appreciated!
Lawrence

Hi,
In iChat go to the Preferences > Account section
GO to the Server Settings tab
Whilst logged off of AIM chnage the port to 443
Log in to AIM.
This is because the regular Login port is 5190.
The AIM Application on a PC or in fact the AIM for Mac application will automatically try other ports including the web browsing port (80) to make a connection.
The port 5190 is above a Threshold of 1024 where ports have to be opened specifically. Using port 443 is below this and also used fro Secure Mail by mail applications so is likely to be open.

Filesharing over uni network

hi, when i had a windows pc we used to use sharescan, i now have this lovely white beast, but despite a month of searching i have been unable to find such software?
is there a piece of software for osx that enables you to search through the shared files on a university network?

IChatAV and file transfer over wireless network

Hi there...
I'd like to let you in on my predicament. Firstly, a bit of background.
I decided to buy my folks an old iMac from eBay in Australia - and pay for their broadband connection - so that I could video chat to them from the UK, and they could see my 5 year old son for the first time in 4 years. Cute, eh?
Well, everything was working fine until I decided to go wireless in my home about 3 months ago. I have a static IP address, and purchased a nice new Airport Express to integrate into the system. I allocated my G5 iMac it's own network address (10.0.1.2), and the base station the master address (10.0.1.1). From there, the base station communicates to the router via the static IP... Sound ok?
Anyway - NOW (or, for as long as I can recall), I CANNOT for the life of me send files over the connection. Video chat and audio chat are fine (although OCCASIONALLY it takes a few goes to be able to see THEM on my computer - I think their bandwidth isn't THAT stable at 512Kbps down and 128Kbps up) - however, the correct ports have been unblocked on the OSX firewall AND the Airport Express base station.
And just so that you know it's not the folks' fault - I can't send documents/images over the network to friends I KNOW are competent (or, at least more competent than my parents!). There's always an error message at the receiver's end, and the file I'm attempting to send just times out.
Has anyone any suggestions as to how I might be able to resolve this problem before I expire from old age?!?
Your thoughts are REALLY appreciated!

Hi Ralph
I can see where that might be the case, but file transfer worked flawlessly BEFORE I went wireless using the same modem. The only way to unblock ports on my router is to turn NAT off - it creates a DMZ, so it permits unhindered 2-way traffic...
It's a pretty confusing piece of kit. Maybe I should just get a Netgear anyway!
I have a laptop on the wireless network as well, and file transfer works a treat between it and the iMac. All I can think of is that because I'm now working on a LAN, there's a blockage to get out to the "Real World" - even though it's easy for video to pass through.
I'll check my unblocked ports again, just to be sure. I'm unfamilar with the term "Jabber" - is that what Apple decided to call one of the elements of iChat? Excuse my ignorance...!

Finding other people on uni network

Hi
I'm pretty new to mac but have my new leopard mac. Im at my uni and can see that there are a lot other people using mac books. With my windows machine i could see the other people in my network and share files with them, but how do I do it with the Macbook/Leopard? I have heard something about Bonjour.
Thanks in advance..
/Robin

At my uni (last time I checked was a few months ago, before Leopard), computers sharing iTunes music with Bonjour would just show up automatically in the "shared" list over the network, so I assume that with the new Finder all Bonjour computers would show up in Finder's shared list. (My home Macs share using Bonjour, and they both just show up in the Finder sidebar). Of course you would need permission to access their shared folders (i.e. their username and password). I believe you also need to turn on "File Sharing" in the Sharing pane of System Preferences.

I want to share my external hard drive over the network

I found a lot of threads and discussions about this, but no answers.
I have a WD My Book External Hard Drive that I'm looking to share over the network. However, when I add the volume to the "Shared Folders" or even a folder within the volume and the "Users:" are grayed out.
When getting info on the volume, Sharing & Permissions says, "You can read and write"
Any ideas?

Hi Keith,
Thanks for your response; however, the first screenshot is through the Sharing settings in the System Preferences.

Problem with using JMF audio over a network

Printing to shared windows printer over wireless network

Hi,
I just bought my wife a MacBook and recently updated it to Leopard (OS X 10.5). I have a Lexmark X5150 printer connected to a desktop PC running Windows XP. I can share files between the two computers no problem either wirelessly or through an ethernet connection through my router. But, I'm having troubles accessing the shared printer through the Macbook wirelessly. If I connect the printer directly to the Macbook, I can add the printer with appropriate drivers no problem. However, when I try to add the printer as Windows shared printer, the appropriate driver doesn't show up in the drop down list. I can navigate to and find the printer over the network fine, but I just can't find the right driver. I'm a newbie to Mac and was wondering if there is anyway to find the driver using Finder or something similar to determine where it physially resides on the Mac. I know it's there because it is automatically selected when I directly connect the printer to the Macbook and add the printer. Any thoughts??

Couldn't figure things out, so I'll just stick with connecting the printer directly to the macbook.

One Answer To Sharing Stubborn/Naff Printers Over A Network

Dear all,
I posted a previous question concerning sharing a Canon i320 printer and got a swift if disappointing answer. Whilst the answer was entirely correct in that it was a fault with Canon's driver and the lack of a CUPS version, I have found an alternative to giving my perfectly working i320 printer a Viking Funeral which may also answer several other peoples problems. Just as well because it probably wouldn't float anyway.
It may not be news to some but there is an application for OS X called PrintFab - www.printfab.net which seems to provide CUPS drivers for most printers, including the i320. This allows you to share your disappointingly naff printer over a network just like one of those proper printers you should have bought in the first place.
I've just achieved a successful printout using the evaluation version of this software. Sadly there's no such thing as a free lunch. This one costs 49 euros in it's basic form but in these ecologically challenged times, it does allow to continue using your current printer. It is presumably cheaper than Airport Extreme which was suggested as an alternative. It did take a while to print so I'm unsure about performance in that area. I guess with an evaluation version, you can check that yourselves.
Hope this helps.

Hi Brie,
I'm not sure exactly what are the 6 steps exactly.... but I did all the check box in ip preferences of both computer.
I found this in the iP help menu
To share your photos on a network:
1-Choose iPhoto > Preferences.
2-Click Sharing at the top of the Preferences window.
3-Select the "Share my photos" checkbox, and then choose your entire library or only the albums, slideshows, or books you want to share.
4-Type a name for your shared items in the "Shared name" field, and a password if desired.
The shared name you enter appears in the iPhoto Source list on computers set up to look for shared photos on your network. If you select "Require password," users will need to enter that password before they can see your shared photos.
DONE ( did not use password)
To look for shared photos:
1-Choose iPhoto > Preferences.
2-Click Sharing at the top of the Preferences window.
3-Select the "Look for shared photos" checkbox.
DONE
Not sure what other step there are to do if any!

You can't connect directly to the external drive, but should be able to use iTunes Home Sharing via the laptop.

I am sharing my macbook pro over a network with windows 7, however through windows 7 I can access my whole computer instead of just the shared files!

Hi Sig,
The issue is that i only want the shared folders to be accessed through windows 7.
Whats the point otherwise to have shared folders?
thanks..

IMac G5 no longer prints to laser printer over ethernet network

I have a small office with 6 iMacs networked via ethernet with a Netgear Router. Printers are connected to one machine and people send to print over the network.
3 iMacs are G5. 3 are Intel. All run OS X 10.5.8.
A month ago one of the G5 iMacs stopped being able to print to a Brother laser printer (which is connected by USB to an Intel iMac). I believe this happened after we downloaded a periodic Apple update. About 2 weeks ago a second G5 iMac developed the same problem. The 1st G5 iMac still prints fine to an inkjet printer connected directly to it by USB.
We have tried re-loading drivers, but no improvement.
Any suggestions as to how we can resolve this?

Hi DaddyPaycheck
The iMacs that can't print can see the printer. We have deleted and re-installed via the printer system prefs too. There weird thing is that you can select the printer and send to print, but for some reason the printer then automatically pauses and you can't resume it. The file is listed by the status is 'stopped'. When you open the printer queue on the Intel iMac that the laser printer is connected to, no print file shows up at all...
We also ran the network diagnostic that you can do when in printer system prefs and that reported that "the G5 iMac could connect to the internet, but not the Server "brother HL 4040CN series-1@ben's-iMac-2.ipp.tcp.local" "
Hope there's a clue in there somewhere...

Error message when using Photoshop over the network

I am currently working with Apple Aperture. My library is on my computer and references files that are saved over a network on a hard drive connected to another computer. I open an image that is within Aperture having set my primary editor as Photoshop. This creates an automatic duplicate of the image within Aperture so that any changes I make in Photoshop will be a second image and will not affect the original. Normally what is supposed to happen is that once I have made my change in Photoshop, I hit Apple+S to save and then it will update within Aperture. However, when I hit to save, I get the following error message:
Could not save "file.tiff" because the file is already in use or was left open.
I know that on my computer and the other computer I connect to that is definitely not open. Not even in Finder. I tried closing Aperture and then saving and I still get the error message. I am not sure what is going on and why I can't save it. Any ideas?

Hi,
Try to save in different location and different format not in tiff like PSD. close the photoshop and repon once and open PSD file and save as into tiff in different location.
just try with this...

HP Laserjet M1132 MFP is too slow over the network!

Hi,
My HP Laserjet M1132 MFP is too slow over the network!
I have connect the printer to a windows XP 32bit SP3 using UBS port. The printer works fine on the local computer but when sharing it over the network it works too slow, for example with print test page it takes about 45 seconds to print and for other documents it takes much longer time.
I have installed the latest driver form HP website and upgrade the firmware it the latest version.
It happens on other Windows XP machines as well.
I connected the printer to my laptop (Windows 7 64bit) and it works fine (No delays over the network) and it seems that this problem have some relations with the windows XP Driver.
I have used local port trick on remote machines (instead of regular method) like this:
''add a local printer;
'new port'
'localport'
\\XPcomputer\HPPrinterName as port name
but still nothing!
There is nothing wrong with the network, we use to use a Samsung printer on the same machines over the network with no problem.
I Really appreciate your HELP!
This question was solved.

BEHZAD_T, how is the printer connected to the network (wireless or Ethernet)? If it is slow wirelessly, I would suggest trying to connect the printer to your router with the Ethernet cord and install it to the networked computer that way.
Another question is, relatively speaking, how close to your router are the Samsung printer and the HP printer? Depending on the distance (and what stands between the devices) there can be a lag between sending a print job and it being received by the printer.
Let me know!
