My Experiments for Truth.

1. Get the structure of test_table from the source database.  > use database1;  > show create table test_table; 2. Copy the Complete CREATE TABLE `test_table` query 3. Remove the "AUTO_INCREMENT=xxxxxxx" Portion from the query. 4. Insert this query to the new database;  > use database2;  > Paste the CREATE TABLE query and press enter. 5. Now the tricky part, the below command will select the last 5 records from the test_table  of database1 and insert into the test_table of database2.  > insert into database1.test_table select * from database2.test_table order by cur_date desc limit 5; Thats all Folks, Cheers.

Why it is called Dirty Cow?   " A race condition was found in the way the Linux kernel's memory subsystem handled the copy-on-write (COW) breakage of private read-only memory mappings. An unprivileged local user could use this flaw to gain write access to otherwise read-only memory mappings and thus increase their privileges on the system. " Who found the Dirty COW vulnerability? Phil Oester How to mitigate this vulnerability? You need to update the kernel and make sure the kernel is patched for this vulnerability. # yum update kernel # uname -r // for getting the installed kernel. # rpm -qa | grep kernel-name // for getting the package of the installed kernel. # rpm -q --changlog | grep -i 'CVE-2016-5195'   - [mm] close FOLL MAP_PRIVATE race (Larry Woodman) [1385116 1385117] {CVE-2016-5195} If this have a result like above , that means the cow is clean now :p How to Build and use the systemtap workaround First you have to insta...

We are all at least generally familiar with the software development cycles, and different software developers use different release schedules according to the testing phase the software is in at the time. For example, some developers use an alpha, beta, release candidate (RC) type of release schedule, and each of these may have varying levels of releases. The cPanel release schedule is very similar to the manner in which Linux distributions are released. cPanel updates in a variety of release tiers. Server administrators may then choose which release version is applicable to their system requirements. The following are cPanel’s current release tiers: ########################################### Stable Release Current Edge Long-term support Each of the above cPanel release tiers represents various stages of the software development cycle. While the final decision to which release version to deploy is entirely up to the organizational decision-makers, i...
