• Juniper JunOS Command Overview and Howtos Switch, Router, Firewall Tutorial Guide


    How Do You Apply Changes You've Made? You can make all kinds of changes to the switch, but remember they are not actually active until you run the "commit" command. This means adding or deleting config options will not have any effect until you run "commit". Under configure mode: root# commit commit complete........
  • Centos installing grub problems suspect gpt problem


    grub> root (hd0,0) root (hd0,0) Filesystem type is ext2fs, partition type 0xfd grub> setup (hd0) setup (hd0) But if you do: root (hd1,0) setup (hd1) it does work, I think hd0/sda had a GPT partition that was not removed properly (what I did was just dd bs=512 count=1 the partition table from another drive since the partition table should be identical). Checking if "/boot/grub/........
  • Mysql how to backup/copy row from one table to another


    INSERT INTO articles_backup SELECT * FROM articles WHERE articleID="118" It is so simple we always recommend people do this when updating their database so you always have a backup. The above inserts the copy into the table "articles_backup" which has an identical structure. It selects the entry from "articles" where the articleID is "118" but of course you can adapter yours to whatever the situation is.........
  • ssh session and port forward or reverse port matching or assocation howto


    Use netstat with the -anpe option. The e option shows the inodes and I do not know if it will always work or if it was by fluke but I was dealing with dozens of SSHsessions and needed to know which session was related to which forward (the PIDs of the SSHand SSHD did not match etc...) Notice the "59560675" and "59560762" those are almost identical, if you find two sets that are nearly identical except for the last 3 digits they may match (in my ca........

  • Samsung C410W/CLP410W not printing in Linux solution


    You need to use the Samsung driver but specify it as a CLP-360 (this is what I used for my CLP365) and incidentally most of these units look identical on the outside on inside (I've been buying whatever the latest C300 and now 400 unit for years which all seem the same with slightly different features that I never use). The solution Once again try specifying earlier models and revisions if the printer doesn't print (it will say it's been sent to the printer bu........

    It's weird because I have a nearly identical box and setup and I can update the ovzkernel-PAE* just fine but on this box it doesn't work. I only get this error with the openvz.repo and not others such as Centos-Base.repo With my other server it works normally: ================ Setting up Update Process Resolving Dependencies --> Running transaction check ---> Package ovzkernel-PAE.i686 0:2.6.18-238.12.1.el5.0........

  • Convert HDD/Hard Drive Partition(s) into non-RAID into RAID 1 using existing data without data loss and without reformatting.


    Before we start I take no responsibility for this, you should have a backup and if you make a mistake during this process you could wipe out all of your data. So backup somewhere else before starting this as a precaution, or make sure it's data you could afford to lose. The RAID 1 Setup (Hardware Wise) I've already setup my 2 x 1TB (Seagate) drives with identical partitions, make sure your new hard drive (the empty one) is setup like your curr........
