How does ACS check redundancy?

Hello

In a router, if you configure the RADIUS server, Ganymede-1 host Ganymede-2, this is how you configure the redundancy of the ACS.  My question is, how does the router check the pulse of each RADIUS server?  By ping or another keepalive mechanism?  What this command do really behind the scene?

What is happening in our environment, is that Ganymede-1 in Windows services keep stops by itself.  We cannot authenticate and Ganymede service does not switch to Ganymede-2.

Hi Ganesh.H,

Thanks for the reply.  Looking at the command documentation, it states:

"If the command is not configured, the timeout interval is 5 seconds."

So it is default configured regardless I enter this command or not. However, this command does not work as TACACS service does not fail over.  Any other idea?

Kevin,

This command is not by default configured in cisco swithces the default setting is 5 seconds if you configure timeout Server tacas only without sepcifying the time in sec.

    How can I check my backup burned restore disc filled properly or does not? He ran for 12 hours. My info is about 117 GB. He did not say, he just says no longer copy of backup disk in the process.

  • How can I check my Mac mini for spyware and other viruses

    How can I check my Mac mini for software spyware and other forms of virus? Recently, I received an electronic invoice which seems to come from Apple on a purchase that I did not. Unfortunately, I answered by clicking on a link that asked me to cancel or manage this purchase that led me to a site that didn't look like an official Apple site. I am afraid that simply by doing so, I welcomed the spyware on my Mac mini hard drive.

    My Mac was purchased in 2011 and runs on OS X El Capitan (version 10.11.6).

    Kind regards

    Politkovskaya

    Receive a fraudulent e-mail for a purchase confirmation, you did not is a very common scam. Remember that you are not misled by providing personal information solicited by this e-mail.

    Unfortunately, I answered by clicking on a link that asked me to cancel or manage this purchase that led me to a site that didn't look like an official Apple site. I am afraid that simply by doing so, I welcomed the spyware on my Mac mini hard drive.

    No harm will come of the fact that you wrote. Fraudulent Web sites that are made to appear as legitimate those who are specially designed to convince you to reveal personal information. If you don't have that, no further action is necessary or justified. Do not install anything, no matter the source or the apparent popularity, in response to one such scam. To do this would be the first step in a path well worn to the misery.

    On the other hand, if you were tricked into providing personal information (like your Apple ID and password) you will need to change your password on Apple ID. Please write back for instructions.

  • How can I check the disc for physical integrity on Satellite P305?

    I have P305-S8838.

    I had some freezing problems earlier this month, and on the notice here, I nu start-up and reduced services a little at a time.
    Now, I have a few more crash but don't know if it's a physical disk problem.

    For example... I have run CHKDSK and does many things and happens at the exact same spot and hangs at step 4 file 5 3498 or 421168 processed.

    I tried to run CHKDSK in SafeMode but tells me drive is locked and it will run when I restart. But the restart put back me in normal mode and get the same hang.

    Now, for more suspicion of a physical problem. I tried to make a disk image with ACronis and same problem occurs because he says impossible to reading data 226 964, 072 sector and ask if I want to ignore and continue. I say yes to everything. Log shows he made about three of these attempts and crashes.

    I ran sfc/scannow and it says found problems that he was unable to fix. The newspaper isn't so long and complex course that all means. I could send these log files if someone can help me understand.

    I ran the test of memory OK.

    I if I could put in DVD Toshiba and certain diagnoses, but when I put in the disk I get this big warning I'll crush, etc and I have chicken.

    This didn't stop me to use the computer, but its all irritating.

  • How can I check if my computer is ok? I got an unsolicited phone call and allowed them to access my computer

    This morning, I got a phone call from an Asian man, saying: he has worked with microsoft, I found it very difficult to understand what he was saying and to rehearse a lot, he mentioned "Alureon" and says that my computer is one of the computers on crash today... He then wen on say that they should do support remotely. to help solve the problem, stupidly and against everything I've known I have allowed him... .it all seemed very alarming... it said my computer was about to crash in a few moments and I had to buy the red shield to protect... I hung up, but they called back... ultimately I told them I wasn't buying any and at this point, he got quite angry and asked me why I was wasting his time. How can I check my computer to make sure they did not hurt? and they can access my computer later? I'm asuming that Microsft had nothing to do with it.

    Hello

    It's a scam.

    If you gave them remote access and you do Internet banking, contact your bank, explain, and change passwords.

    If you use your online credit card, cancel and get a new one issued to you.

    And the only way that willl you know that you are free to them is to backup your data and do a clean install of your operating system.

    Either these so-called "Microsoft" Tech companies want to sell you a worthless software, or remote access to your computer to try to steal your credit card and bank information and also achieve an identity theft on you.

    Microsoft does not contact you unless YOU have made prior arrangements with them to do.

    There is an article in the link I'm you provide at the end of this one

    Vista and Windows 7 updated drivers love then here's how update the most important.

    This is my generic how updates of appropriate driver:

    This utility, it is easy see which versions are loaded:

    -Free - DriverView utility displays the list of all device drivers currently loaded on your system.
    For each driver in the list, additional useful information is displayed: load address of the driver,
    Description, version, product name, company that created the driver and more.
    http://www.NirSoft.NET/utils/DriverView.html

    For drivers, visit manufacturer of emergency system and of the manufacturer of the device that are the most common.
    Control Panel - device - Graphics Manager - note the brand and complete model
    your video card - double - tab of the driver - write version information. Now, click on update
    Driver (this can do nothing as MS is far behind the certification of drivers) - then right-click.
    Uninstall - REBOOT it will refresh the driver stack.

    Repeat this for network - card (NIC), Wifi network, sound, mouse, and keyboard if 3rd party
    with their own software and drivers and all other main drivers that you have.

    Now in the system manufacturer (Dell, HP, Toshiba as examples) site (in a restaurant), peripheral
    Site of the manufacturer (Realtek, Intel, Nvidia, ATI, for example) and get their latest versions. (Look for
    BIOS, Chipset and software updates on the site of the manufacturer of the system here.)

    Download - SAVE - go to where you put them - right click - RUN AD ADMIN - REBOOT after
    each installation.

    Always check in the Device Manager - drivers tab to be sure the version you actually install
    presents itself. This is because some restore drivers before the most recent is installed (sound card drivers
    in particular that) so to install a driver - reboot - check that it is installed and repeat as
    necessary.

    Repeat to the manufacturers - BTW in the DO NOT RUN THEIR SCANNER device - check
    manually by model.

    Look at the sites of the manufacturer for drivers - and the manufacturer of the device manually.

    How to install a device driver in Vista Device Manager

    If you update the drivers manually, then it's a good idea to disable the facilities of driver under Windows
    Updates, that leaves about Windows updates but it will not install the drivers that will be generally
    older and cause problems. If updates offers a new driver and then HIDE it (right click on it), then
    get new manually if you wish.

  • How can I check if I have a virus in the BIOS and what is the difference between formatting and full format in Windows 7?

    Hello

    Recently I found a rootkit on my computer, especially rootkit.tdss.tdl4. Of after I read that I got one of the best!

    I have two questions:
    Firstly - how can I check if my BIOS was hit without blinking? I read that this Trojan horse could have started exactly from the BIOS, and very likely to stand again after doing a clean install. I have a laptop HP seems like flashing procedures require to disconnect the disk hard - is this true for laptops?

    Second, is how I format to ensure that clean the MBR? I have Vista and want to upgrade to Windows 7. I have Windows 7 upgrade ultimate disc that can do a custom install which should format entirely. Tell me if I think too old school here but should be low (or zero) format is required? From what I've read, the function of full format of Windows 7 should be as powerful as the low level. is that correct? I don't mind the overtime work as long as I don't have any problems (at least with this Trojan) later. I also fear that upgrading Windows 7 disk might not have all the features of formatting as a full version, which is a nonsense?
