  • mga sir, up ko lang... what if wala sa akin ung root password? posible ba kung gagamitan ko cya ng bootable cd like clonezilla. then from iso convert to vm?



    Meron kaming centos server na naghohost ng inhouse system namin. Wala kaming root access dahil ibang company ang nagdeveloped ng system. Medyo maraming issue sa system kaya gumawa nalang kami ng sarili naming system at ngayon gusto na namin bitawan ung lumang system.

    Pero bago sana namin bitawan gusto namin iback-up ung data / system para kung sakali man eh may copy kami at puwede namin ma-access kahit offline lang ung mga lumang data.

    Question. Possible ba na i-convert ung server into virtual machine / vm. Para kahit VM lang eh ma-access namin ung system and reset ung admin password kung puwede.

    1. yung hicolors.no-ip.org is nakaregister na po sakin.. testing lang kaya free lang po ginamit ko.
    2. im not sure po about this. isp po namin is bayantel.. pero i think meron po..
    3. router supports DMZ set-up (linksys)

    sabi ng manager ko ginagamit nya din ang gantong set-up sa dvr to view our company cctv from their house..(using no-ip)
    this has been disable together with team viewer kasi baka port nito is same sa http. pero di pa rin gumana.
    nagtry na din akong magbago ng port..

  • ^thanks sir!
  • @ansonley
    better to have the root user/password. yung VMWare converter need nya yun. kung clonezilla no need in the process pero once you boot the system (Virtual) you must have the root, you need to adjust things inside the configurations etc.

    mind also kung naka hardware RAID kayo, NFS mount, NAS, SAN etc. hindi pwede isama yung mga partitions/logical drive sa convertion
  • bump lang para sa question ni PCntials_Tech. hehe
  • @PCntials_Tech

    most ISP they implement NAT (one to many) meaning lahat ng subscriber isang public IP address lang ginagamit and they do double NAT
    e.g

    Bayantel
    Public IP Router/Modem:WAN - LAN
    182.18.xxx.xxx <=> 10.17.xxx.xxx 192.168.0.0/24

    you can ask your ISP about your setup baka me input sila dun

    There's a way to change the root password in Linux via booting from the GRUB menu.

    During normal start up, kung may option ka to select what OS to load, select the default "linux xxx" and hit "e" to enable editing the boot loader argument.

    Then look for the line that starts with the word "linux" or "kernel"

    replace the "ro" with "rw init=/bin/bash"

    Hit F10 or whatever the instruction is to boot the operating system

    You should end up with the root command line. Type in "passwd" to change your root password

    Just tested this with Ubuntu and CentOS. Your mileage may vary
  • @hajji
    yes bayantel nga ang culprit.. yung plan pala namin hindi pang corporate.. home use only, hahaha(nagtitipid si bossing). pero ive heard they are planning to upgrade..
    babalikan ko nlng itong set-up pagnag-upgrade na sila.
    salamat sa tulong nyo.
    ldap+samba na muna siguro pagtutuunan ko..
  • ^there goes my dreams. haha wala talaga pag-asang mag port forward pag residential line sa bayantel :(
  • Anyone here na naka-kuha na ng Oracle Linux Systems Administration test?
  • @paaaatsooo
    hindi nga tlga siguro pwede ang residential line.
    itinigil ko nga nga ang pagconfigure kasi alam ko wala rin tlga mangyayari.hehe
    im not really a sys ad dito sa company namin. pasideline-sideline lang. actually inventory control and production planning ako. maliit kasi ang company kaya ang daming slash. and plan ko din tlga magshift into sys ad balang araw.
    LDAP & SAMBA muna..
  • @PCntials_Tech
    ako din di talaga sysad sa work, pero sa bahay, sysad-kuno ako. practice practice lang. hehe
  • @MiG25Foxbat
    I haven't encountered any Oracle Linux, maybe soon siguro, RHCE/RHCSA meron at LPIC1/2

    this is recommended sa mga SysAdmin who works with Oracle product specially Oracle Databases

  • Thanks hajji. Nag-hanap-hanap ako sa web at ito nakita ko.
    <click here for link>

    Ito yung details ng exam: <click here for link>
    P7,062 yung exam!!! Although I have been using various Linux distros for years parang di ako confident kumuha nito. Sayang naman kung babagsak lang. May alam po ba kayong reviewer?
