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...

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.

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.

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

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.

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.

Upgrade to Leopard zapped my network with PCs

Tiger worked fine, but once I upgraded to Leopard, my networking setup just got fried, to a degree. Although I can still see my XP PC, calling it through the smb process, my Mac won't show on my PC's network service.
Using Tiger, I would turn on the three computers (the third uses Vista, and no, I've never had a problem with neither of the three OSes) and each would see the other two. They would show up automatically on Finder, then I would click and login on either of the others.
Now, with Leopard the Windows-run PCs don't show up in "Network" and I have to call them through the smb procedure using the "connect" button on Finder.
Why doesn't Leopard recognize the computers on the network. All my settings are checked so the other computers can exchange files, etc.
The second issue is that my PCs can't see the Mac, whereas before, it used to show up in the Workgroup tab of network. Even when I click on discover computers near me, it just won't find my Mac.
Has something like this happened to others and is there a quick solution -- I want my Mac back!
Roxy

I had a current backup of the user home folders, but no complete bootable backup image. So I did an erase and install and then copied the backedup user folders to the new system. Everything's fine now.
It turns out there was some unreadable data in one of the user folders (maybe due to bad sectors(?), so maybe there was other corrupt data required for the upgrade to work). The concerning thing is this issue was not found by Disk Utility, Disk Warrior, or the OS upgrader.

That was so because this sort of CPU requires some "alternative" microcode to be loaded into it upon startup.
One published workaround was to replace certain file in the SP2 package with its predecessor from SP1,
another (more solid, IMHO) - to upgrade the BIOS of PC so this revised microcode is loaded with BIOS. At this point in time, I believe, the revised Mega 865 BIOS is available as an official release.
You are right, the issue is only with certain processors; see also (this includes the m-soft workaround too)
http://support.microsoft.com/default.aspx?scid=kb;en-us;885626
This revised bios is not available IMHO, one of our forum collegues managed to get a beta version of a new bios, which does the trick. If you need it give us a shout.

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.

My Macbook all of a sudden can't open Skype, Word, Excel, Powerpoint and Entourage. I have done research and read that it has something to do with malware and viruses. Please help I feel like I have tried everything!

This started a few days ago, when I noticed skype would not open and keeps quitting unexpectingly. Now it's all of my microsoft office programs. I have read horrible things on the internet about creeps building some sort of 'backdoor' through Mircosoft Word and are now able to access my macbook. I want to feel safe again and I want to be able to use skype again. I think I will delete Microsoft office until I find/can afford a better version.
I have tried deleting and re-installing the programs, PRAM-ing my mac, doing the utilities organizing thing, and I downloaded 4 different scanners (Cleanmymac, VirusBarrier Express, Bitdefender Virus Scanner, and ClamXav) to help get rid of this and only one scanner found a small file that was harmful. I need some advice PLEASE!
Thank you for your time!

Thanks MadMac0 I followed the instructions in Terminal for the link you sent and all my programs open again!
Sorry I'm just getting to this now, but a lot going on today in this front. There is now a "K" version of Flashback and perhaps more going on.
A couple of considerations you need to be aware of.
It's clear from the results of your testing that the reason you were infected is because your Java is out of date, so it's important that you keep all your software up-to-date going forward.
But even that won't protect you from this new "K" version as Apple has not released the patch to it yet, so I encourage you to disable Java in all your browsers and consider doing so for everything by opening Java Preferences (located in /Applications/Utilities/) and unchecking the box next to "J2SE 6.0" and any other box that might be checked. If you find that some application(s) you need must use Java, then you should enable it only to run that application(s).
We cannot be certain that what you did totally killed the Trojan, so your best bet would be to restore your Mac back to where it was before you were infected using TimeMachine. If you don't have a TimeMachine backup or cannot determine the date of infection, then your safest solution is this one:
Courtesy of Linc Davis:
I suggest you take the following steps immediately:
1. Back up all data to at least two different devices, if you haven't already done so.
2. Boot from your recovery partition (if running Mac OS X 10.7 or later) or your installation disc (if running an earlier version of the Mac OS), launch Disk Utility, and erase the startup drive. This action will destroy all data on the drive, so you must be sure of your backups.
3. Install the Mac OS.
4. Reboot and go through the initial setup process to create an account. Don’t import anything from your backups at this stage.
5. If running Mac OS X 10.6.x or earlier, run Software Update.
6. Restore the contents of all the top-level subfolders of your home folder except “Library” from the most recent backup. You can also restore the files in the Library folder, but don’t restore any of its subfolders; only the files contained in those folders, and only if they’re visible in the Finder. Don’t restore any hidden files or folders, no matter where they are.
7. If you’re running Mac OS X 10.5.x or earlier, disable Java in Safari’s preferences, and leave it disabled until you upgrade to Mac OS X 10.6.8 or later, including all available updates. The Java web plugin is unsafe to use under older versions of the Mac OS. Note: I’m not referring to JavaScript, which is unrelated to Java, despite the similarity in the names.
8. Change every Internet password you have, starting with banking passwords. Check all financial accounts for unauthorized transactions. Take this step only after you’ve secured your system in the preceding steps, not before.
9. Reinstall your third-party software from fresh downloads or original media, not from backups which may be contaminated. If you use any third-party web browsers under Mac OS X 10.5.x or earlier, disable Java in their preferences, as you did with Safari in step 7.
Of course, as of this morning you should follow my instructions for disabling Java and ignore his, at least until Apple gets that Java patch out.
Pay particular attention to Step 8 no matter what you decide to do.

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.

Trouble with a Dell Printer on a network with PCs.

I've searched the forum and found only trouble with people getting their files to print on a mac, but I can print, only it's terrible quality while the PCs are printing out high-quality. It's a Dell 5100cn, and I've installed the updated driver from the Dell website, and called them for help, but they said they couldn't help with a Mac problem. I'm connected through an IP address over a wireless connection.
Has anyone help?
Mac OS X (10.4.5)

It was a simple problem after all. Sadly my hard disc was about to snuff it. I changed disk, reinsalled Tiger and all is as smooth as ever.
