Network color control -

HP Officejet Pro 8500A A910a How is color controled with an ethernet network connection? Printer properties have been set to black ink only, the printer continues to print in full color. The printer setting webpage has no option for color.

Had you been using wired networking before you began to set up wireless? Had you given yourself Administration status with command-u, or were you using default TCP/IP and AppleTalk windows? Had you used command-k from the TCP/IP window to name a location (configuration)? Failing that your automatically assigned configuration would have been Default. It is worth your while from the standpoint of security to use these facilities, and, if necessary to set up a different configuration for wi-fi, lest there be any conflict in TCP/IP Preferences between an older wired or dial-up configuration and the wireless. If you wish to overwrite the old configuration by editing it, that is possible. You can choose, if you wish, to maintain several different configurations and connection modes with different names. As an administrator, you are able to change between them at will in much the same way as OS X provides, although the windows and access methods look different.

Query: Best practice SAN switch (network) access control rules?

Dear SAN experts,
Are there generic SAN (MDS) switch access control rules that should always be applied within the SAN environment?
I have a specific interest in network-based access control rules/CLI-commands with respect to traffic flowing through the switch rather than switch management traffic (controls for traffic flowing to the switch).
Presumably one would want to provide SAN switch demarcation between initiators and targets using VSAN, Zoning (and LUN Zoning for fine grained access control and defense in depth with storage device LUN masking), IP ACL, Read-Only Zone (or LUN).
In a LAN environment controlled by a (gateway) firewall, there are (best practice) generic firewall access control rules that should be instantiated regardless of enterprise network IP range, TCP services, topology etc.
For example, the blocking of malformed TCP flags or the blocking of inbound and outbound IP ranges outlined in RFC 3330 (and RFC 1918).
These firewall access control rules can be deployed regardless of the IP range or TCP service traffic used within the enterprise. Of course there are firewall access control rules that should also be implemented as best practice that require specific IP addresses and ports that suit the network in which they are deployed. For example, rate limiting as a DoS preventative, may require knowledge of server IP and port number of the hosted service that is being DoS protected.
So my question is, are there generic best practice SAN switch (network) access control rules that should also be instantiated?
regards,
Will.

Hi William,
That's a pretty wide net you're casting there, but i'll do my best to give you some insight in the matter.
Speaking pure fibre channel, your only real way of controlling which nodes can access which other nodes is Zones.
for zones there are a few best practices:
* Default Zone: Don't use it. unless you're running Ficon.
* Single Initiator zones: One host, many storage targets. Don't put 2 initiators in one zone or they'll try logging into each other which at best will give you a performance hit, at worst will bring down your systems.
* Don't mix zoning types: You can zone on wwn, on port, and Cisco NX-OS will give you a plethora of other options, like on device alias or LUN Zoning. Don't use different types of these in one zone.
* Device alias zoning is definately recommended with Enhanced Zoning and Enhanced DA enabled, since it will make replacing hba's a heck of a lot less painful in your fabric.
* LUN zoning is being deprecated, so avoid. You can achieve the same effect on any modern array by doing lun masking.
* Read-Only exists, but again any modern array should be able to make a lun read-only.
* QoS on Zoning: Isn't really an ACL method, more of a congestion control.
VSANs are a way to separate your physical fabric into several logical fabrics. There's one huge distinction here with VLANs, that is that as a rule of thumb, you should put things that you want to talk to each other in the same VSANs. There's no such concept as a broadcast domain the way it exists in Ethernet in FC, so VSANs don't serve as isolation for that. Routing on Fibre Channel (IVR or Inter-VSAN Routing) is possible, but quickly becomes a pain if you use it a lot/structurally. Keep IVR for exceptions, use VSANs for logical units of hosts and storage that belong to each other. A good example would be to put each of 2 remote datacenters in their own VSAN, create a third VSAN for the ports on the array that provide replication between DC and use IVR to make management hosts have inband access to all arrays.
When using IVR, maintain a manual and minimal topology. IVR tends to become very complex very fast and auto topology isn't helping this.
Traditional IP acls (permit this proto to that dest on such a port and deny other combinations) are very rare on management interfaces, since they're usually connected to already separated segments. Same goes for Fibre Channel over IP links (that connect to ethernet interfaces in your storage switch).
They are quite logical to use and work just the same on an MDS as on a traditional Ethernetswitch when you want to use IP over FC (not to be confused with FC over IP). But then you'll logically use your switch as an L2/L3 device.
I'm personally not an IP guy, but here's a quite good guide to setting up IP services in a FC fabric:
http://www.cisco.com/en/US/partner/docs/switches/datacenter/mds9000/sw/4_1/configuration/guides/cli_4_1/ipsvc.html
To protect your san from devices that are 'slow-draining' and can cause congestion, I highly recommend enabling slow-drain policy monitors, as described in this document:
http://www.cisco.com/en/US/partner/docs/switches/datacenter/mds9000/sw/5_0/configuration/guides/int/nxos/intf.html#wp1743661
That's a very brief summary of the most important access-control-related Best Practices that come to mind. If any of this isn't clear to you or you require more detail, let me know. HTH!

Network UI control

Hello,
I have been searching through any and all documentation I can find regarding using the Network UI control to consume XML but have been hard pressed to find anything explaining event handling in a sufficient manner. I have a very basic tree which consists of multiple nodes which can, at most, have 1 child. I'd like to wire this up so that a user can click on a node triggering an event that allows me to programatically launch a Web Dynpro component.
I feel that I am close however I cannot get the code right. Does anyone have a useful link or perhaps a code snippet illustrating how to do this?
Thanks in advance!

If the problem is unclear, please let me know and I can elaborate as needed!

Color Controls for Calibration?

Is there any way to access color controls so that I may calibrate my 23" CD with a Colorvision Spyder and PhotoCal software? The Apple calibration routine is pretty vague, and I need the CD to match a calibrated CRT sitting next to it. Thanks.

"...if some software can adjust the colors, why can't I?"
You can if you want to run the Apple color calibration tool (Sys Prefs / Displays / Color / Calibrate). But if you want to use the Spyder, you have to use the Spyder software which is designed to work with the device.

Identifying Color Controls when calibrating

I am trying to calibrate my monitor with a Spyder3 Elite colorimeter and partway into the setup process I am being prompted to identify my displays Color Controls, in particular if I have Kelvin Presets, Kelvin Slider and/or RGB sliders.
After many searches, and even a chat with Apple tech help, I am still unable to find if any of these settings on my system exist. I'm not convinced that just because I can't find them, doesn't mean I don't actually have them. I have a mac pro desktop version 10.5.8 with 20"cinema display.
Any help is much appreciated

Several monitors on the market have a menu system and a method for making a lot of adjustments, including color adjustments. Apple displays do not have such adjustments or any kind of menu system at all. All adjustment is done on the host system, meaning the graphics card in the Mac Pro.

How to convert U32 value obtained from color control of front panel to float(SGL) for use with IMAQ Draw ?.

I am trying to get user color inputs from front panel and use it in IMAQ Draw. I need to draw an oval of a certain color in a background of another color. Both these color values are user input. The problem is IMAQ Draw requires SGL color value and the color controls of front panel give U32. I have tried conversion VI's which hasn't worked. HELP !!!

Jake,
I think the color control can be wired directly to the input, but I am not positive. I don't know of any color conversions that would help.
Make sure your image is a color image. You can't draw colors on a grayscale image.
You might want to consider using overlays, which appear on top of the image but are not part of the image.

Color control dashboard

Is the color control dashboard new to iMovie '08 or not?
Seems to be a bit like the color tool in FCP.

It seems that the dock was the guilty thing.
I killed it and now my background is back...

Networking color laserjet 3800 printer with Windows 7 OS

I have a color laserjet 3800 that is networked in an office of 5 computers using Windows XP pro OS. I just purchased a HP pavilion Slimline Windows 7 64 bit OS computer. The networking and printer networking set up was a breeze until it came to connecting the 3800. I have downloaded the PCL 5, 6 and universal drivers. When I go to add printer as a network printer and choose the 3800 it gives an error of not being able to find a driver. I tried to manually find the driver but it does not find a match in PCL 5, 6 or universal driver. The link below clearly shows the 3800 to be compatible with windows 7, but I cannot get it work.
http://www.microsoft.com/windows/compatibility/windows-7/en-us/Details.aspx?type=Hardware&p=HP%20Col...
The network absolutely sees the printer and lets it be chosen but does not let it get installed on the windows 7 machine.
Thank you for any assistance.

Same Problem here. Does no one have a solution?

Can I get back the color control bar?

After a 5 hour download and install, the most noticeable change is that Apple changed the left-hand side control bar from colored to all gray.
Frankly, I've been very disappointed with Apple's design changes lately, and this one is another example, although, I love the new translucent trash can. I've figured out work-arounds to many of the changes I find most offensive (e.g. my folders are no longer Yosemite-native neon blue.)
Is there a way to get back the colors on the left-hand side control bar in iPhoto?
I don't mind digging through hidden folders and re-building the icons so that my interface looks good again. Any suggestions are appreciated.

If you want to restore the color to the Finder's sidebar give the open source application cDock a try. You can change the Dock's background scheme (I use transparent) and add color icons to the Finder's sidebar:

EPSON printer update v2.3.1: color controls now dimmed @ print dialog box

I have lost the ability to control color in the Print/Print Settings dialog box after this update. The Ink tab is dimmed and set to "Color," the Color Settings tab is also dimmed and set to "Off (No Color Adjustment)," and the Advanced tab brings up only information about the Colorsync profile. The graphic file (Photohop) I'm printing from is a grayscale file.
There is no difference in the Print dialog box between having Photoshop manage the colors or having the Printer do it.
My concern is that the printer will now be consuming color ink, but the actual prints appear to be using only the matte black.
Anybody else run into this? Should I be concerned?
Thanks

From PHOTOSHOP (CS4) In the printer driver menu, the COLOR MATCHING pulldown shows the choices are grayed out. But go to the PRINT SETTINGS pulldown. There you should be able to select BLACK/COLOR Ink, color settings if appropriate (VIVID etc)...
Apparently not all programs gray out the COLOR MATCHING boxes - a demoed a RIP that does not do this but it has other issues (ImageNext2.1).
Also CS4 has the ability to completely disable color management (used for printer profiling), but some apps cannot do this with this driver (ImageNest2.1, DataColor Spyder3Print)

Simple color control panel.

My largest beef with Lightroom is that for the most part, the HSL sliders are good for creative color but difficult and slow for color corrections. And the white balance controls are terrible for color corrections when used to an RGB system as used in Photoshop (RGB Histogram, RGB Curves and probably the most useful, least appreciated tool the Color Balance controls.)
What I suggest is either a panel on the main Develop module with essentially the Photoshop Color Balance controls (perhaps plus a density slider) with the ability to switch to an RGB Histogram or Curves mode as well. Or better yet, an additional module that has these controls plus Density, Gamma, Contrast, Saturation, Vibrance and a customizable display of one or several images for easy color corrections and display of reference images and/or a selected image in the set to help aim color and skin tones towards.
Any improvement in the speed and ease of color correction would be great.

Printing to Canon ImageRUNNER 3200 network color printer

Hi folks,
I'm the lone Mac user working in a corporate Windows environment. I've succesfully been able to use IP addresses to print to various HP printers, but I'm so far unable to print to the aforementioned Canon ImageRUNNER 3200 color laser printer. I downloaded Canon's driver for Mac OS 10.1/10.2/10.3/10.4 and tried adding it to the printer center as an IP printer but it won't print. Then I tried adding it using Canon's IP printer utility (I saw it in the pull down menu from the print center) and that doesn't work either. It seems to see the printer on the network, but just won't print. Any suggestions would be greatly appreciated.

I was doing some Googling and saw the device Queue Name for ImageRunners is "print." Try entering that in Printer Setup.

Color control in Fireworx CS3 mac

Hi,
I just bought a wide gamut screen (HP LP2475w) which is fantastic for photography and graphic design but when I use Fireworks, Flash and a web browser the RGB colors are very strong and vivid. It's expected when using a wide gamut LCD panel. Is there a way to control the color gamut in Fireworks CS3 to mimic a standard LCD screen (sRGB)? The same as Illustrator and Photoshop have color management tools.
If not, does FW CS4 offer this?
Thanks
Mic

When you use Fireworks with both a wide gamut monitor and an sRGB monitor, is there a difference in the colors? If there is, there's a problem. The colors that most of your audience will see are the colors on the sRGB monitor not the colors on the wide gamut. This means that in order to judge colors accurately you have to view your layouts on the sRGB monitor and not your wide gamut. That's a problem.
If Fireworks used color management correctly, the colors on both monitors would be identical (within reason). Not all of us have a spare sRGB monitor to switch to when we have to do color specific work. I just can't believe that Adobe has gone yet another version of CS without fixing this issue. Especially as more and more designers are buying wide gamut displays.

Confused - Color control with multiple utilities available

I have Photoshop 7, Monaco EzColor, NVidia 6800 card with a control panel, and a SyncMaster 193 Plus digital monitor with control software. ALL of these can change the monitor qualities. I use Monaco to profile my scanner and printer - it does a great job; it can profile the monitor also.
My question is: what would be the best overall CM system - which combination of controls (or which one)would be best (the monitor control utility has stopped working and I have turned it off).
I would appreciate very much any advice born from experience.
Thanks
vangogh

Thank you, Chris, sounds authoritative.
One more.... some system changes are forcing me to recalibrate printer and monitor (as above). I have a Photosmart 8250 HP. Printing from Photoshop AdobeRGB, I have choices in the Photoshop Print With Preview window, Color Management (or Output) and the Monaco printer profile with Perceptual (which I've been using).
In the HP Properties dialog I have a Color tab with a Color Management box, ("ColorSmat sRGB, Adobe RGB, Managed by Application, and ICM). Up until now I've been using "Managed by Application".
I am assuming this is the best route. Of course, the Monaco calibrating settings would have to be similar. Your comments, please?
Thanks
