Firmware 1.2.7.76 crash and the loss of the ssh keys SG-300

Hello

2 of our 7 switches SG-300-52 updated new firmware now.

Our preliminary findings:

-(boring): switch regenerates it of ssh host key on every reboot. If I export the configuration, the keys can be seen, but they are

apparently not stored and are regenerated each time the switch restarts.

-(critical): by chance, we connected a port that was part of a port configured without lacp channel (channel-group mode 1) to a nx7k

the port configured for the lacp Protocol. At this stage the SG-300 stops responding completely, even for the network regarding the serial console. With both sides

properly configured for lacp, all right.

The Ruedigerl, the critical part of your post is expected behavior when you connect to a configuration of channel-group incompatibility. Covering tree essentially denounces the switch that requires a reboot. This is true in all switches, including the catalyst series, spanning tree will make a loop and making unpleasant problems.

    Hello

    What version of BIOS your M400 installed?

    Test the RAM for problems using the Memtest CD of www.memtest.org

    And update the drivers (fingerprints, display, sound etc...).

    I was using my MacBook today and it crashed and the dock turned silver, I restarted the mac and it was always the same, then I loaded the disk utility and checked the disk and it says disk is fine. It flashes inconsistently gray and the dock has transformed money! I tried to restore Mac OS and then also the same!
    OS El Capitan

    This can help:

    Reboot safe mode (it is a slow process):

    -stop of the mac

    -Start up the mac in shift, press and hold until you see appear it to progress bar, so you can let go

    -When everything started, connect

    -Once connected, stop the mac once again, nothing else is necessary.

    -restart normally.

  • My main computer crashed and the data has been retrieved from the hard drive, including all of my Outlook Express dbx files

    I'll provide too much information because those of us who are computer knuckleheads think that everything is important since it is a mystery to us.

    My main computer crashed and the data has been retrieved from the hard drive, including all of my Outlook Express dbx files. There are four years of e-mails in these files and critical that I be able to open them.

    My only working computer running XP. It has Outlook Express is installed on it and was once used for e-mail, but not more and not implemented with my ISP to send or receive if it matters at all. Other that the sending and receiving of all the other functions of the OE program appear to be operational.

    I have read many explanations on how to open the files dbx on different sites - all is completely different and most seem well beyond my skill level.

    There is a fairly painless way to open these files? I don't want to try anything that could damage them. Please... any solution please guide me through in its simplest form - I am 64 but pretend you are explaining the process to a 7 year old. Yes, I'm that lame!

    Sorry for writing a novel and thank you to all who take their time to help the ignorant!

    I advise you to immediately copies of your DBX files restored. Save the duplicates in a place safe, and don't mess with them.
    Then try using one of the various tutorials that you have found on the Internet by using a copy of your DBX files restored.
    I did it a few times, but years ago and I DBX http://www.techrepublic.com/forums/questions/how-i-open-corrupted-dbx-files-in-oe/ visualization tool
    You just continue to make attempts, using a tutorial after another.
    As long as you have these unchanged copies of backup of your DBX files, you should survive it - other than frustration. Email PC remains a mess.

  • Satellite M40X-286: energy saving and the E - key utility does not work on Vista

    First of all, sorry for my bad English.

    I managed to install Windows Vista Ultimate 32-bit on my Satellite M40X-286. Everything works, except for the energy saving and the E - key utility. I tried the added value of packages of other TOSHIBA models, but they all give an error message during the installation. Is there a solution for this problem?

    Now I can't change the speed of the processor and the brightness of my screen, and I can't even adjust these settings in a power mode. The only way to change the brightness is manually using the FN + F6 and F7 keys.

    Kind regards
    Stijn.

    Please don t be crazy about me, but there is no problem at all. The situation is quite clear.

    First: tools and utilities are similar, but in most cases have to be adapted for each laptop model. It may happen that some tools work on the different model of laptop, but this does not mean that he has to work on each model.

    Second important fact is that Toshiba does not Satellite M40X support for Vista operating system and I guess you won't be able to use this tool. In my opinion, it is not so important, because all the energy-saving settings you can find in Vista power options.

    For utility E - key, I don't see a solution. If you use OS not supported, you must live with it.

  • I installed Vista in a Virtualbox VM and the product key does not work, how to fix this? I use the same product key supplied with the computer originally.

    I bought a Dell Precision T3400 of Dell Financial Services and it came with Vista Business installed.  I installed a new hard drive and installed Vista in a Virtualbox VM by using the recovery disk that came with the computer, and the product key does not work for activation.  I get a message that says I need to activate Windows, but he says that the product key is not valid.  How can I fix it?

    Thank you

    If you have reinstalled the OEM of Vista Business copy on the new hard drive, as Bill says you can't also use it in a virtual machine.

    You can only reuse your OEM of Vista professional copy if it is no longer used on the computer. Do you have what operating system installed on the new hard drive? It was an upgrade copy or complete the license?

    If you used a license to upgrade to another edition of Windows to replace your copy of company then Vista Business license is still in use (for upgrade) and you cannot reuse it in your virtual machine.

    However if you replaced Vista business with a copy of the full license of another edition then you are able to use the OEM copy in a virtual machine, but only on the same computer. You must use the product key from COA to the label on the computer. The product key is put in the copy OEM cannot find the SLIC table on the host motherboard. You must use the phone activation from within the virtual machine. Click on start in Vista Business and typing "slui 4. Do not meet the audio guests until it asks you if you want to speak to an agent. Explain that you have completely replaced the OEM copy with a copy of the full license of the new windows and now want to use the OEM copy in a virtual machine on the same computer. Agent will then give you the activation string. Remember that the virtual machine is not transferable to any other computer.

    Hi yayatisharma,

    Product key Finder programs are USELESS for Vista computers preinstalled, as they find the product key of plant manufacturers, which is used for installations of mutiple during Assembly of the computer.

    This key will not help you reinstall Vista!

    If you communicate with HP they will post you Recovery DVD for a low price to reinstall Vista and they do NOT require a product key

    Or ask the use of the recovery Partition, which must be copied to the hard drive HP

  • Keypad does not and the volume keys not working not

    I had this problem since I got this laptop, the pad and the volume keys don't work.

    I tried to uncheck keys mouse in Control Panel, but they still do not work, I put on a frame, so it makes a noise whenever you click on capslock and numeric keypad. However when I press numlock that noise does not turn on, I just wanted to make sure that there is a way out maybe solve this before I take it to the store.

    Looks like a defective keyboard that should have been replaced under warranty.  It won't be cheap to replace.  You will need a technician because it involves a lot of disassemble very delicate pieces.  Make sure that the technician replaces with the correct part.  There are a lot of almost the same thing available.

  • Floppy disks to install Windows 7 and the product keys are exclusive to each other?

    Floppy disks to install Windows 7 and the product keys are exclusive to each other?  Or can I use a disc that I have to restore the windows on a second laptop and activate it with a different product key?  It is not a question to find out how many users I can put in place, but whether the disk and product key are mutually exclusive.

    As long as the product key matches the edition, it should work perfectly, no exclusivity.

  • Record and the product key of Windows 8

    Unfortunately, my husband has one person to put up my new PC for me and I do not know now what is my windows product key and whether or not it is registered.  How will I know (the PC came with Windows pre-installed).

    If it was built by an OEM System Builder, then the product key must have been connected to the computer on a certificate of authenticity. If this isn't the case, it could be on the envelope that came with your PC. Otherwise, you must contact the manufacturer and ask him if he is or consider purchasing a product key for your installation.

    How to buy additional keys:

    Press the Windows key + X

    Click System

    Click on see details in the Windows Activation

    Click on the link: buy Windows to another computer

    http://www.Windows.com/buy

    Yes, you may be prompted to go through the installation routine with just the web installer of 5 MB, but you don't actually have to download, simply to purchase and the product key will be presented to you in the Upgrade Wizard (you also a copy is sent to your email address).
