DVI / VA Switches and Splitters

Hello.
Can anyone recommend an DVI / AV switch to split a source taken from a PM G5 and a standard AV signal (such as Sky Box / VHS Player etc.). The DVI / AV switch also has to support audio not just on the AV channel but the DVI channel in order to switch audio and visuals (if possible).
If such switches exists could anyone recommend one for this purpose.
The plan is then to send the switched signal to a splitter to distribute it to multiple displays, probably an AV splitter to send to 4 or 5 sources such as a projector and plasma TVs.
Alternatively i was going to use a DVI splitter to route the signals to various plasma / cinema displays and to a DVI projector.
Can anyone offer some advice? Thanks.

I've gone thru several between work (2 offices) and home and after using different models and having them die or exhibit difficulties with new larger monitors, I've been happy with the Belkin KVMs that I've had for the last couple years. But I foresee a possible problem with the wireless part. I think you'd better put out a call for reports on success/foibles using a KVM and wireless mouse/keyboard. What I'm not sure about is how the computer will react to losing contact with wireless and then getting it back again.

A discussion of DVI KVM Switches

Hi Gang
I have an APPLE Cinema Display 20" LCD A1081 MONITOR with two Power Mac G5's.
I researched DVI KVM switches, and tried out an Iogear Model GCS1762;
http://www.iogear.com/product/GCS1762/
With DVI, (as opposed to VGA), there is a neccessity for a 'hand shake' between computers, as it tries to figure out what to do. The Iogear doesn't connect instantly, consequently producing glitches, lines, video noise for a few seconds before it clears up when toggling back n forth.
Gefen on the other hand, apparently realizing this issue came out with something called a DVI detective; http://www.gefen.com/kvm/dproduct.jsp?prod_id=4714
They also make a (probably better) switch;
http://www.gefen.com/kvm/dproduct.jsp?prod_id=5040
Has anyone had any experience with either of these?
Thanx
Mike

Recommendations for DVI KVM Switches?

I wish to share the same USB wireless keyboard/mouse, and monitor between my Macbook and PC.
Has anyone tried this with a DVI KVM switch, and can you recommend which one to use? They're a little pricey, so I'd like to get comments from actual users if possible...
Thanks

DVI KVM switch to use with iMac and Cinema Display

I currently have a 20" iMac that I use with a 20" Cinema Display. I'd like to share the Cinema display between the iMac and a Dell computer. Assuming this can be done, are there any recommendations for a DVI-KVM switch? Most important is no loss in video quality when the Cinema display is used with the iMac. The Dell is seldom used and even a straight DVI switch without mouse and keyboard sharing would be OK.

I am also trying to link a Mac Mini and a HP PC with an nVidia FX5500 graphics card via a KVM switch. The mini works fine but the PC does not sync up and the screen is blank and the little white light on the lower right is blinking.
Any news on your question would be appreciated

DVI video switch

Hi all -
Big fan, long time reader, first time poster =] I started out with a Motorola (comcast) HD dual tuner cable box with a Sony Grand Wega KF-60WE610 for my TV. This rear-projection LCD has a single DVI input as its HDTV input (Video 7). When I got my mac mini, I thought the DVI out to S-Video adapter would be ok to use for display purposes . . . however, when I hook the mac mini directly into the DVI input of the TV, the difference is incredible! So I have been looking at DVI KVM switches, however, I don't need the K or the M seeing as how I have the Bluetooth Keyboard and mouse. So all I really need is a DVI switch. I saw Gefen has one: http://www.gefen.com/kvm/product.jsp?prod_id=1819. It has 2 DVI inputs and 1 DVI out. This sounds like what I need . . . this seems like a common problem with the mac mini hooked up to a HDTV as the display . . . is this the common solution? Is there a better way around this problem? Is there a better 2/1 DVI switch available? I have read alot about the DVI KVM switches, however everyone seems to ***** about the K or the M in the KVM switching capabilities . . . any input would be greatly apprecieated.
Thanks!

I have the exact same issue. I tried buying a new receiver as a component to add to the setup in my den with the TV. Many new receivers now feature HDMI switching. But I ended up returning the receiver and learned the lesson that these first generation HDMI receivers are not quite ready for prime time. It wouldn't pass the DVI signal from the mini to my TV, even though a direct connection between the mini and the TV works fine.
Personally, I am just going to wait for a better generation of HDMI switching receivers, even if I have to wait until gen 3 (2008?). But if you want the have switching today, someone else on this forum pointed out that monoprice has some cost effective 2- and 4-port switches. I have no idea how well they work, so you might want to find out what their return policy is should you buy one and it not work out.

DVI KVM Switch Suggestions

Hi I would like to use a DVI KVM switch because having problems with the VGA ones... does anyone recommend a brand/model that works with the mini and a PC?

I had two things I wanted to achieve with a KVM, and they tax most KVM switches. The one I have now works great. The one I am happy with is this one from Addlogix:
http://www.neutronexpress.com/prod.cfm/322180/ADDLOGIX/KVM-201DVU It is old other places but when last I looked it was cheapest here, at ~ $190, including cables.
What it does that is "above and beyond":
1. It is DVI, rather than USB. My PC and monitor were already DVI. It works great, and up to 1900x1200 or so. Not all DVI KVM switches actually work well.
2. It works great with my wireless Logitech MX mouse/keyboard combo, which doesn't play well with most/many KVMs.

DVI KVM Switch??

Hi,
I have a G5 running tiger (soon to be running leopard hopefully) with a DVI cinema display.
I have a PC that I use for testing my work on the Web. I was able to switch back and forth easily with a Belkin KVM switch back when I was using a VGA monitor. But I can't seem to find a KVM switch that works with my current setup.
Any suggestions?
Cheers!

Would this model work for me?

How do I use switch and case statements to fill more than one other field?

Hi all,
I'm new to the community.
I'm trying to make an existing form more user friendly for my coworkers. I want to use a switch and case approach in a drop-down list field so that the selection fills two seperate other fields with different info related to the selection.
I can already do this with one field, but if I add a second target field under an existing case the text doesn't appear there when I make the selection from the dropdown.
Basically, I'm asking if I can do this:
switch
(sNewSel){
   case "1": // Selection 1    Row2.Field1
= "text for field 1";
    Row1.Field2 = "text for field 2";
    break;
etc.
It works if the "row1.field2" option isn't there, but not when it is present.
Any takers?

I'm not sure if I will be able to send you the form. There may be too much to redact.
Would this last bit of code in the cell affect anything?
if
(bEnableTextField)
{Row2.Field1.access
= "open"; // enable field
Row2.Field1.caption.font.fill.color.value= "0,0,0"; // set caption to black
That is, do I also need to repeat the same thing for the second target cell (Row1.Field2)?
What would be possible hang ups that would prevent it from working correctly?

By the way, I'm not sure if my other attachment posted. I am trying again.

I've just hooked my 20" iMac up to my Toshiba 37" HDTV using a mini dvi-HDMI adapter, and works well, EXCEPT for the green tinge (or hue) that is showing up on my TV. Any suggestions or ideas?

I've just hooked my 20" iMac display up to my Toshiba 37" HDTV using a mini dvi-HDMI adapter, and everything works well, EXCEPT for the green tinge (or hue) that is showing up. Everything else looks pretty good though..... The color that is on my iMac is still good, Its just green on the TV.
Anyone have suggestions or ideas?

Try opening the Display System Preferences, then click on the Color options in the Display preferences window that appeared on the Toshiba display. Click on the Calibrate button and follow the instructions for creating a custom ColorSync profile that will hopefully solve the green tinge issue. The Apple Display Calibrator Assistant software that launches when you click on the calibrate button will walk you through the process.Assuming that the green tinge is minor and that you don't have a more serious cable or hardware issue, I am hopeful the results will be worth it.

Screen has a bluish tint after fast user switching and then warning tone

Hi all I'm having a bit of a problem that I hope someone can help me with. First the details, I have a MBP bought in late '07 and running Tiger. I was doing full backups using "Backup" and I also had Safari, iTunes, and Word open. I briefly switched to my other account using fast user switching and when I returned to the original account the whole screen had a blue tint to it. Like the color profile was off. This has happened before and a restart usually cures it, I haven't restarted yet but I am fairly certain it will correct the problem this time too. But is there anyway to prevent this? My second question is the one I'm more worried about. It also has happened before but usually when using more CPU intensive applications. When I went to System Preferences and opened up the display preferences in an attempt to correct the previous problem I heard a very loud tone. Like some type of warning tone, it was loud enough that it startled me. I had iTunes playing and after the tone the music got very quiet but relaunching it brought it back to normal. I'm just wondering is this some type of warning tone? Is it something I should be concerned about? Besides the music everything else seemed unaffected, although the previous times that this has happened usually when using handbrake there was noticeable problems after the tone (like applications crashing). All of these problems are gone after the computer is restarted though. Does anyone have any insight on these issues? Thank you.

OK I ran TechTool and everything passed except for the volume scan. Then I checked this with Disk Utility and the HD failed for a few minor reasons, like invalid block count. I repaired it using the fsck -fy command in single user mode. The computer seems a little faster now. I don't know if this error is related to the beep in any way, I may try talking to an Apple genius to see if they know. Since it seems like pretty minor errors I'm not too worried about it but it does seem to be happening often. The last time I had this error was when I posted a question here about it which I just checked was on March 1st. So this error happened again after a little more than 2 weeks which seems excessive to me. Any thoughts?

You can use EEM scrip to achieve the same. Just check EEM scripting in the community directory for some examples.

How to get "fast user switching" and network shares playing nice

I've been alternating between banging my head against a wall and reading every forum I could find to try and get a reasonable compromise between using "Fast user switching" and sharing a folder from a file server. It baffles me how the network share/mount model of OSX/AFP is completely killed by fast-user-switching; this is a big problem with Apple requiring users to be actively logged in to share music/video from iTunes which therefore essentially requires fast-user-switching if anyone else wants to use the computer. (anyone find it odd that you can share files without being logged in, but sharing songs requires an active login for each user who is sharing? Apple: time to make iTunes sharing a service!)
For the sake of example, lets just say I want to share my /Groups folder from my desktop and have it be accessible to my laptop. Here are all the things that I tried:
Apple Method 1) Share /Groups in the Server.app on the desktop (running Lion Server), use finder on the laptop and drag the share icon to "Login Items", alternative use a startup Apple script using "mount volume" Both of the options work and will mount the /Groups folder under /Volumes/Groups, of course when the second person logs in via fast-user-switching (and occasionally the first person for no apparent reason), they will get /Volumes/Groups-1 since /Volumes/Groups is already taken. Tomorrow we log in a different order and now the previously /Volumes/Groups-1 user has their mount at /Volumes/Group and vice versa. Any links, aliases, finder sidebar references, and application settings which pointed to yesterday's location are now BROKEN. Not very user friendly to my mother-in-law who is trying to find those pictures of the kids and doesn't know anything about mount points. I also can't reasonably mirror the file location structure on the desktop so that application preferences that are synced between the two (portable home directories) work. fail.
Apple Method 2) Use automounter and set up by hand direct maps for /Groups or an indirect maps for the children of /Groups. Now it will automatically get mounted to /network/servers/SERVER/Groups/ on the laptop and on the desktop it will automatically create a similar symlink structure so that the same path (/network/servers/SERVER/Groups) work both on desktop and laptop. Cool. Except when the second person logs in, the /network/servers/SERVER/Groups/ mountpoint is already owned by the first user and they don't have any permissions to access it. Fail.
Apple Method 3) Use mount_afs and specify directly the mount-points. Have each user have their own startup AppleScript which mounts /Groups to a different location (e.g. /Users/Shared/username/Groups) that way they don't conflict with multiple users. On the desktop, set up symlinks from /Users/Shared/username/Group to /Groups so that it will be the same as the client and applications settings will work when synchronized back/forth by portable-home-directories. Will it work, yes it does, but what a bear to maintain. Is this really what I should expect to do just to have multiple users on my desktop and laptop (which again is essentially required now if I want to do any type of iTunes sharing). This can't be what apple expects.
What I ended up doing - the "not quite apple" solution.
Non-Apple Method 4) After a read of "Autofs: Automatically Mounting Network File Shares in Mac OS X" (http://images.apple.com/business/docs/Autofs.pdf) at the very end there is a single paragraph of "Kerberized NFS": "A Kerberized NFS mount can have multiple connections from multiple users, each using the correct user’s credentials for each transaction. This allows administrators to support multiple users, each authenticated with their own credentials to the same mount point. This is very different from AFP and SMB mounts," (emphasis mine)
It appears that by using good 'ole NFS (abeint with Kerberos for security!) you can actually have multiple users on the same mount point. Roughly following the guidance at https://support.apple.com/kb/TA24986?viewlocale=en_US. What I needed to do was:
1) create /etc/exports on my desktop and add a single line "/Groups -sec=krb5". The existence of /etc/exports triggered a start of nfsd which no longer has any GUI options in Lion.
2) Add a line to /etc/auto_master on my laptop "/- auto_mymounts" to reference a new direct map.
3) Create /etc/auto_mymounts and add a single line "/Groups SERVER:/Groups" to create the direct map.
THAT'S IT. Three lines in three files.
Now when I log into my laptop, there is a /Groups that is a network mount of my desktop's /Groups, same location AND it works for all of my users, even simultaneously.
In the end I'm happy with what I've got, but man was this a difficult path just to support fast-user-switching. In Lion, Apple appears to be getting away from NFS (no longer turned on by default and remove from the GUI controls) but clearly this really useful functionality which doesn't exist in AFP.
I'm really curious, after all this work. Any other ways to accomplish this?

In my example above, yes I chose to mount the share "Groups" to the top of the root since that is where I put it on my server and I wanted to keep them similar; but that was just my preference, it isn't a requirement. You can export and mount from other directories.

Branch office setup with L3 switch and router with IOS security

Hello,
I am in the process of putting together a small branch office network and I am in need of some design advise. The network will support about 10-15 workstations/phones, 3-4 printers, and 4-5 servers. In addition we will eventually have up to 25-30 remote users connecting to the servers via remote access VPN, and there will also be 2-3 site-to-site IPSec tunnels to reach other branches.
I have a 2911 (security bundle) router and 3560 IP Base L3 switch to work with. I have attached a basic diagram of my topology. My initial design plan for the network was to setup separate VLANs for workstation, phone, printer, and server traffic. The 3560 would then be setup with SVIs to perform routing between VLANs. The port between the router and switch would be setup as a routed port, and static routes would be applied on the switch and router as necessary. The thought behind this was that I'd be utilizing the switch backplane for VLAN routing instead instead of doing router-on-a-stick.
Since there is no firewall between the switch and router my plan was to setup IOS firewalling on the router. From what I am reading ZBF is my best option for this. What I was hoping for was a way to set custom policies for each VLAN, but it seems that zones are applied per interface. Since the interface between the router and switch is a routed interface, not a trunk/subinterface(s), it doesn't seem like there would be a way for me to use ZBF to control traffic on different VLANs. From what I am gathering I would have to group all of my internal network into one zone, or I would have to scrap L3 switching all together and do router-on-a-stick if I want to be able to set separate policies for each VLAN. Am I correct in my thinking here?
I guess what I am getting at is that I really don't want to do router-on-a-stick if I have a nice switch backplane to do all of the internal routing. At the same time I obviously need some kind of firewalling done on the router, and since different VLANs have different security requirements the firewalling needs to be fairly granular.
If I am indeed correct in the above thinking what would be the best solution for my scenario? That is, how can I setup this network so that I am utilizing the switch to do L3 routing while also leveraging the firewall capabilities of IOS security?
Any input would be appreciated.
Thanks,
Austin

Thanks for the input.
1. I agree, since I have only three to four printers, they need not be in a separate VLAN. I simply was compartmentalizing VLANs by function when I initially came up with the design.
2. Here's a little more info on the phone situation. The phones are VoIP. The IP PBX is on premise, but they are currently on a completely separate ISP/network. The goal in the future is to converge the data and voice networks and setup PBR/route maps to route voice traffic out the voice ISP and data traffic out the other ISP. This leads up to #3.
3. The reason a router was purchased over a firewall was that ASA's cannot handle routing and dual ISPs very well. PBR is not supported at all on an ASA, and dual ISPs can only be setup in an active/standby state. Also, an ASA Sec+ does not have near the VPN capabilities that the 2911 security does. The ASA Sec+ would support only 25 concurrent IPSec connections while the 2911 security is capable of doing an upwards of 200 IPSec connections.
Your point about moving the SVI's to a firewall to perform filtering between VLANs makes sense, however, wouldn't this be the same thing as creating subinterfaces on a router? In both cases you are moving routing from the switch backplane to the firewall/routing device, which is what I am trying to avoid.

What are the major differences between a Access Switch and Aggregation Switch w.r.t Carrier Ethernet domain?

In a Carrier Ethernet domain,Could someone please help me understand what's the basic difference between Access Switch and Aggregation Switch both in terms of s/w and h/w functionalities. MEF deals OAM,CFM, EVC provisioning only at the access edge switches. Do we need to repeat all these at the aggregation level? or is it just used for routing purpose? Do we have a separate Fault Management at the aggregation level?
