Vlan interface will not respond to ping
cisco 2651xm router
IOS: c2600-ipbasek9-mz.124-9.T1.bin
I have two vlans configured on this router as follows:
interface Vlan1
ip address 172.16.1.30 255.255.0.0
ip nat inside
interface Vlan2
ip address 192.168.0.1 255.255.255.0
ip nat inside
from a pc on 172.16.1.x I can ping 172.16.1.30 and get a response.
But from a pc on 192.168.0.x if i ping 192.168.0.1 I get failure, and I've tried this on more than one pc. The 192.168.0.1 vlan will not respond. This is baffling and I can't work out why. Thanks if anyone can help.
thanks for your response:

My K2000R will not respond to Logic Pro 9
My K2000R will not respond to Logic Pro 9
So the MIDI Sport has an A or B port selection?
MIDI Out of the interface to MIDI In on the K2000r
In the inspector on the left, (on a test track) set MIDI channel to ALL and try both the A & B ports.
Is the MIDI Interface plugged into a hub? If so try it on a port.
Did you upgrade anything recently, there was a version of OSX that stopped a bunch of USB stuff from working.
Is 10.7.5 correct? -
I just created a new profile/user on my MacBook Pro. My pointer/mouse on my trackpad. It works fine in my older user profile, but when I go to the new profile my mac will not respond to clicks. The Mouse moves but will not click. Already tried restarting and the pram zap. The problem starts when I log out of my main profile. I get to the login screen and my laptop stops responding to clicks. When I manage to make my way back to my main profile the mouse works perfectly. Should I just delete the new profile and try again?
If the modem is also a router, either use the modem in bridge and run pppoe client on the TC.. that is assuming ADSL or similar eg vdsl. If it is cable service.. and the modem is a router, then bridge the TC.. go to internet page and select connect by ethernet and below that set connection sharing to bridge.
Please tell us more about the modem if the above gives you issues. -

If you updated to 6.1 & the problems began then - you might have Glims installed...

this box with three options: learn more, save to my Yahooa1 ID, No thanks, just save to this computer, will not respond when any option is selected. It will not go away. It covers other tabs making them useless.
Did you ever figure this out? I bought my iPad last week to use in my business as well. I assume you are trying to use alldata? That is where I noticed this same issue. I had problems with identifix working with safari but downloaded a different browser and that works fine. Alldata does not work with either browser. The main difference is that on identifix if there is only one engine selection, it automatically selects the only option and continues to the home page. With alldata you have to make the selection manually even if there is only one option. Honestly if I can't get this to work I am going to return the iPad as it looses a significant amount of usefulness to men

Hello, so today I realized that my iPhone with iOS 6 is frozen on the music. I can get back to the home screen but I can't get the music player to work because its frozen on the w's and will not respond to touch. I would be grateful for any help on this.
Hi deamayfield,
Thanks for visiting Apple Support Communities.
If your Music app is unresponsive, try restarting/resetting your iPhone:

My iPod classic (2007) 80 GB FROZEN SCREEN (Now Playing window showing the song that is suppose to be playing, will not respond to buttons, Will not SYNC, iTunes does not recognize it AT ALL when I plug it in. Will not shut off, will not charge... pretty frustrated, I updated it recently (within the last 10 days....Has anyone had similar experience? If so was it fixed? Please post any help for me... thank you... I am pretty frustrated right now.its fixed!! After posting my problem with the FROZEN ipod classic (2007) 80 gb a screen popped up with similar subjects that I did not find in my original search. 'Rich Fleming' in the community posted a suggestion to someone with a similar frozen issue and it WORKED when I tried it.
hold the 'menu' and the 'circle' buttons down at the same time, KEEP the pressed until the apple appears. and now it is working. Hope this helps others. -

Imac 27" Intel Core7 CPU 16 Gig RAM. Screen goes black and will not respond except with a push of power button. Second monitor connected via displayport continues to display fine. Apply Store did full hardware diagnostic and all is fine. Did clean wipe from Mavrick back to Mountain Lion but problem remains. Apple Store can do no more.
I did some more digging, it appears to be a backlight problem only. I can see the screen very dimly if I use a bright flashlight in a very dark room. It also seems to run ok if the brightness is turned down a LOT.
So I'm thinking this is a LED driver board issue or the display itself. I'll open it up and check the connection between the two and see if I can get any more clues. At least I can use it somewhat now by dimming the display significantly... -
What are IP's 10.126.20.1 and 209.148.243.165 and why do they not respond to ping??
I have been trying to understand some issues in my internet connections.
If I do a traceroute to say, netflix.com I and get this rather long response:
The 10.0.1.1 is my airport and I can ping it successfully.
the 10.126.20.1 appears to be in my router, based on the IP, but it does not respond to a ping (timeout).
and
209.148.243.165 appears to be owned by Rogers cable, but also does not respond to a ping. The remainder seem more or less reasonable.
Can someone tell my if there is a reason the two above IP's do not respond to ping? Does this imply something is wrong in my part of the network?
I am a TSI customer who uses the common carrier services of Rogers Cable and I have been told my modem is faulty even though internet access, not withstanding the above questions, works well.
The modem is a Thomson DCM476. I am able to ping its IP, however the tracerout does not include the above IP's
Can someone please lead me in the right direction?
Thanks
Barry

My guess at the 10.126.20.1 address is that this is indeed the IP address of your router on the WAN side ... and, as you surmised, it is being provided to your router by your ISP via the Thomsom modem. This looks like a case where the ISP has assigned you a "Public" IP address on their private network. That is, your router does NOT have a Public WAN IP address. This usually is not an issue unless you needed to run servers on your local network that required access from the Internet.
If you are sure that Rogers is supposed to provide you with a public WAN IP address, then either they are not or the modem is faulty as they have indicated.
The second IP address, in question, 209.148.243.165, is indeed, assigned to Rogers Cable. This may be one of their DNS servers for further routing of your traceroute command request.
BTW. It is NOT unusual for owners of networking devices on the Internet to block ping requests. -
My ipad has locked-up, it has frozen while running an app, and will not respond to any button, what do I do?
It simply stays on the same screen image, and does not respond to anything. When I plug it into itunes, there is no indication of its presence.
The ipad's clock has also stopped.
eekTry a reset:
Hold the Sleep and Home button down for about 10 second until you see the Apple logo. -
The programme is loaded and installed on my PC, but will not run. It will not respond when I click on Finish.
