• Windows 7,8,10 and Server 2008, 2012, 2016, 2019 Read Only Attribute Won't Go Away


    I have seen this in a few rare cases after a reboot, where all folders and files will have the Read Only Attribute. If you uncheck it, it will just come back. It is more of a filesystem issue in Windows than a configuration issue and it looks like when Windows detects a badly corrupted filesystem that it will make things read-only, sort of like Linux would. If you are Administrator or the owner of the folder and this is happening it is probably due to the reasoning mention........

  • MySQL: table is marked as crashed solultion


    myisamchk can fix it But be careful and use the right options to avoid losing data. In fact if you haven't you should make a backup or at least manually copy /var/lib/mysql. Replace "YourDB" with the name of your database Replace "yourcrashedtable" with the name of your crashed table. The -o option is the safest and should avoid dataloss whereas -r is more aggressive and is a last option (I have lost data using -r and........

  • Dell Perci 6/i Firmware Upgrade Guide Tutorial


    One thing to remember is that you need MegaCli to do the flashing. You also need the correct file,I tried at least 2 different Perc 6 firmwares from Dell that kept getting rejected as corrupt by MegaCli(they were really the wrong version). I have an external PCI-E Dell 6 Perc/I butI chose images from the 'Integrated" on motherboard version as it was allI could find. They are different, and below is my first time finding success.........

It also assumes you set a local IP (be sure not to overwrite your existing IP) on eth0:0 (note the :0) as 192.168.1.10 and it........

    A lot of people become nervous (and understandably so) when checking their auth or security logs, in Centos /var/log/secure and see dozens, hundreds of even thousands of attempted logins to various services, especially SSH. Of course you could manually block these people/IPs but no one has time to read the logs like that, what if some program or script could do it for you? This is what denyhosts does for you, it checks the logs and based on a certain number of failed SSH attem........

That shouldn't be necessary but it was the only way to make yum stop quitting after the first package or two.

    I've never understood how to enable and disable services for different run levels in Debian based distros, it's just weird, annoying and doesn't make sense. I much prefer chkconfig from RHEL. Just install the package called 'rcconf' and be done with it. rcconf makes things easy for you. apt-get install rcconf Reading package lists...
