 This is Suresh, I am the CSR team in CSC department, today I am talking about the Linux installation and Linux basics commands, how many people knows the Linux already experience, so many people knows right, so already how to install the Umundo right, so if you knows just listen me that other people do not know I will tell you that how to install that. So and today I am talking about the Umundo 18.4 LTS. So what are the features is available for 18.4, so previously you are using for 16.4 LTS everybody, so only people use it for 18.4, so you started right, okay. First I am telling about that 18.4 features you have to update at the 5 years of 2023 available of the updates and supports, then the stable of kernel is 4.15 it is updated in for the latest one, then update of the Libra Office 6.0, then the latest things for that geonome for that expert environment and faster to improve the boot updated, then I will tell you for the minimum system requirements, so if you want the minimum system, you can have minimum the 2 GB RAM and dear core processor and 25 GB hard disk space is enough, if you installed DVD or USB how to use for the installation and all. If you want to download Umundo how to 2 types, you have to directly download on the Umundo site, other way you have to go for IITB FTP site also, okay if the link you can easy to within a minute you have to download that more than 1 GB file, okay I will tell you that. After that if you want to bootable USB or how to write the DVD how to use for 2 applications start up the creator or you don't boom, you have to download from Google, it easy to download it, once you download that and then update at net boom, then install essence, I will tell you one by one the step by step, for the only installation you have the 2 types, try Umundo or install Umundo, without you have to install you can choose for the try Umundo, I will have to choose for the install Umundo, if you click on the installed Umundo, there is the option for the select the language properly, then for the installation type, you have the 2 types, normal installations, otherwise the minimal installation, mostly use people use for normal installation, then if you want to choose the that part is after you have to click on then go ahead, then this is the main important of the steps. So some people are using for that 2 OS, for multiple OS you are using that for example if you want to windows, if you want to use multiple OS, first you have to install the first 2 windows, then how to choose for Umundo, then how to use that, if you have the only single OS, you have to go for directly for a RSD, whatever you want to install it, but if you want to use multiple OS, you have to choose something else, then you have to give the proper, it is for your what are the hard issue connected, if you have connected for 2 or more hard issues displayed properly here, then it is the file system, how to you created the file system, most probably how you are using that, just you click it for that Umundo, just you click the slash folder, you have to click directly, most of the people use like that only, but you do not go like that, first how you create a give the boot file system and home and slash and where swap area, what is the use of give the swap area, anybody knows that sorry, you have the virtual RAM, you have to you have your system have 2GB or 4GB, but you want to increase the virtual RAM, you have to give the swap area, then you have for example, you have the 4GB RAM, they have give for 8GB, system will be performance is very good, then for what are the different with home and slash, anybody knows home folder and slash folder, yeah it is a root folder, what is the difference is root and home, yeah for example, if you give for root folder for everything, for how your system is corrupted, you not get the any file, for the user file and all, if you separate your give for the home folder, for the user files everybody store on the home folder, if you windows is for the your Umundo is corrupted, you can just you have to reinstall only for Umundo file, then your home folder is safe, for user file everybody safe in that, so most probably how the follow the step, your system will be good and performance is also good, so what is the use of your using separate for the where folder, so what are the where folder is involved, so what for example, you are using for that web service and all right, for example, web server, how to install the Apache and Wamp and all, you have to you have to store on the Wamp folder only, so if you give the separate for the your browser and web server is will be performance is good, that is why we separately we provide for the where folders, then we have to select one by one, for example, we have the what are the ESTs, do you have the any file systems in Umundo, what are the file system is knows, what are the file system in windows, ntfs then only n only ntfs only, fact that it was yeah, for the window for the Linux, you have to choose for the EST file system only, why you want to choose for windows first to install the windows, after that how to install Umundo, if I install Umundo is possible how to install windows, why what is the reason how, anybody knows, so because the main problem is for the file system, for the ntfs you have to readable form for any OS, but he has to only for readable only for Linux, if you install Linux file is not able to open on the windows for systems, but for the Linux you have to open for the ntfs format, for example, if we installed Linux, you have to open the windows file, whatever the system program files also have to open it see that, but in Linux you cannot able to see the ntfs file, then you have to select, the file size you have to select for 1 by 1 the primary and beginning then boot, what are the mount pointer, for the slash folder or where and whatever is separate you have to select 1 by 1, this is for the home folder I separated, then root folder and swap area, if you swap area there is no for the file system, because it is the virtual RAM, once you have once you create at fully then you go for that next project, so when you create a automatically for that continue you select the language, what is the use of you select the language, everybody thinking about only for language you have select, for the main purpose if you select the language when you go updated that time you have to select that nearest your server in Moombudu server, if you want to update anything, if you select for us you have to select for that your server only connected, so most probably you select proper locations, then you have to select the username and the computer name, the computer name is you know the variable is the host name, if you give the host name properly then only you connected for the terminal via, somebody you give for the hyphen and underscore and like that, then you not able to give the proper connectivity, so you give the host name is properly, then username and password everything you give properly then, then how to install Moombudu, so after that once you install the Moombudu, what are the things you have to do it, do you know after install it go to open the terminal, how to update the latest kernel under, once you update the command how to open, what are the e of w and do you know that e of w, it is for the firewall, for the system firewall how to enable it, then only your system will be safe, so how to use for the sudo yes w and enable then check the status, it is enabled or not, otherwise you have to go for GUI mode, if you have to install the command of sudo update install, gfw on y, if you install it, how do you have get it for the GUI mode, you can control whatever anything, for the e of w mode, what is the use of the firewall, if you want to particularly you allow the some particular IPs, if you want to open only for particular for TCP, IPR, FTP, UDP, whatever you want allow for the you can control from that firewall, so you know that command is very useful in features, so after install the GU mode, how to get it that application like that you have to allow and deny what are you want port, so is for the supporting things, most of the people using windows, so the most applications available on the open source or so, for example VLC is available in windows also the GIMP, everybody using for the photo surf, for the same alternate software is available of GIMP also, print of the paint, then Calber is order whatever you want to use, that the Chromium browsers and the screen recorded tools and lightweight package of install that Debian like that stop is a music software, so I give the some sample examination, this is for the umudu installations, so basic commands, so everybody using that basic commands of umudu, so open the everybody know how to open the terminal, so on how to create the directory, if I am using for mk directory and source file, for the what are the source name, you have to create it for the created directory, if you want to change directory, you have to use for cd slash whatever you want, for example you have the some where www HTML whatever you want the file is, if you want to immediately change you have the cd slash, the file going to directly for a root folder, then print the working directory, if you want to order the file current directory, you want to see that, you type the pwd command, if you go for directly on, what are the directory will be displayed, what are the list file and directories, if you want to use ls command, how do you leave for the, what are the file and all, then print, if you have the doubt, you have don't know about that help and then you can use for the man command, it is useful for what are the command, if you have the doubt, any command you can use for the terminal man, what are the command you will be there, type it, it is explained properly, then the search guide you are the man pages, this is the appropriate copy, how to display the what are the commands and all, then how to create the files, how to create the file command is for types, how many file you want created, how to own by own you have created, do you have any other command of created files, v i, then then beam, then lot of command we have that, you can use that, if you want to remove the file you have to use for the command of r m, then file name, if I want to own file I have created for remove that, if I want to multiple file deleted, how will you use that, yeah good, then for the I want to create, remove the directory I can use for the r m slash r v and directory, what is the meaning of r v, regress use, okay good, now what is the move, there is a command of the move directories, if we want to own directory to another directory or if we want to connect it one file to another file, so I use for the move command, okay mv, so second for the read search and find, if we want to print the file content, how we are using that, I have to use cat or the file name, okay it is very useful, then read and reach the text file, for example I have the own file have the huge content, I want to for example is the thousand lines is there, when I use for the touch command it is going for last only, so that time you have using for less, then what are the file name is why coming for the what are the window size display one by one, okay what is the if I want to for there is one file I have the few huge file lines, if I want to particular lines I want to print it, that time what are the command you have to use for head, for the what are the file line the file type, okay if you use that command you have to use for that what are the file will be printed, okay if you want to last line if I want to print it, so I like that if I want to middle of the file line for particular line I want how we will print it, somebody knows, so you can give for as if a two hundred lines you can give for the head and what are the file line number then you print it directly, okay so how to find the directories, if I want to have the bin folder I have the lot of files, I want to particular file I want to find in for terminal, the time you have to use find source for the folder name what is the file name the size and all, if I give like that all file will be displayed, if I I have the PDF file as the more PDF file but I want to display only for the more than 5 MB file, so the time you have to use for the size and plus for him or that the file size you are displayed directly you can find a file, how many people using grub, no, right what is the use of grub, search the particular file inside, if you use for example you have the same like you have the particular you have the whole lines of the file, if you want to particular word for example for this file where the password in the folder there is not of user is there but I want to know who is the nobody uses links, if I using grub what are the content then the file name if you displayed, you want to display what are the things, you see very useful of the grub command in your feature, then what is the search regress in the directory, there is for example you have the for example your name is Rajesh, their file is I do not know how many Rajesh is there, so I want to highlight that what the Rajesh name in the file, so that time you are using the grub and the array, what are the content you put it, it is easily highlighted of what are the content in the search folder, then pipe and the output of the applications, same like if you want to the what are the file permission and all you have to use for ls and all that then grub for the rewrite, for the whole folder have the read and permission I do not know that, but I want to rewrite permission for the folder, that time you are using for the ls command, then give for the gripping build, then you have the content, it is displayed display or that, then user and permissions, how you know do you really use the who am I, it is for the current user who are using that current user, how to change the user, already I am in the user, I want to change the username, how you change it, for example I am the Rajesh, I am the Rajesh account, I want to change that Arjun account, how do you change it, anybody knows sorry, I have to change just a su, then change the username not a anybody's stand and tell me I do not know, if I want the if I want to change the user just you have to for su, then change the username, okay so automatically change the command, if you are in the root user, you want to go for the normal user, the time you are using for su command, then you have to change the username, how all the logged and user, there is two types, how to check the logged users, one command why you type for wdn display, another command, how to check the logged users, what are the things, there is another command of last, if you type the last command you have the history of what are the things you have to display on the terminal, on the files and folder permission, I think most probably everybody knows the files and permissions, okay, for the read and for write and execute them, okay, if I want to change the permission of own folder, that time you have to use for ch mode, 7, 7, 5 for what, rewrite, read and execute, read and execute, read read and execute, so what are the combination that is, 7, 7, 5, owners, group, others, okay, it is owners, it is groups and others, you are the destination, if I want to change the permission you have to give the ch mode, now what are the file content, permission time, then how that, which file you want to change it, you can give directly, if you want to aggressive change mode, for example if you give like that, only for the folder only will be changed, if you want the in build sub folder you want to change, you can give for the aggressive for minus r, then you have to use for the destination and view the slash, it is automatically changed for the all the sub folder also, so that is same, relax file permission of the user group or others, change the owner permission of the root user, how to change the ownership, if I want to the file name, if I create the file name, what are the file ownership is available, if I created one file, for example I create for touch, I create txt, one dot txt, what is the file permission they give on that, so normally they give for the current user for root and root, okay, for the what the current user you are using that, that user it automatically for root or rajas, if I want to change the permission of ownership, the time you have to use for ch1 and regularity, then root whatever the user you want to change, for you want to rajas or the user or group whatever you want to change, you can give the destination, the file permission will be changed, what is the use of the file permission will change, for the main purpose sources, so my file I do not want to use other people, so that I have to give the permission, other people not able to open the file, okay, for the network related, so how to know the, how to ping the IP, right, if I want to check that your another machine is working or not, so you have to use the ping command, then you type the directly your IP, okay, what is the cn5, do you have the meaning of cn5, anybody try this, the cn5, if I give the ping and the IP address, this automatically pinging for continuously, if we want they give the count on 5, for the 5 time only spinging, if I give for 10, it is giving for 10 times, automatically the file execution stops, that is why we are using for cn5, so if you want to check that IP address in your system, you are using IP config, everybody using the IP config, what is the difference in IP config, you are telling me that, any other command in IP config possibilities, so if config only for the IP address is displayed that, if you have the if config slash a, some command, if you are checking on the net, there is a lot of command, so if we are using for if camping, you have to display that whole driver's list for the LAN and VAN and Wi-Fi, what are the IP address, what are the driver's name, everybody is displaying on that in the IP config, okay, so if you want to, everybody download on your machines on the browser only, if I want to terminal, how to you download the files, that time you are using for wget, so what is the meaning, I know that you are using for wget, then you have the for the link directly, right, so what is the meaning of the c, the cning means for is a continuous, for example the file is automatically disconnected for the due the internet failure, the time you are using for minus is, automatically get the resume, that is download the file, is for the that command, so if you use for the remote command, if you want to connect remotely you are missing, so most probably you are using SSH, right, so SSH that root and IP address, so normally if you connected, what are the problem is affected in SSH, somebody knows, what are the problem is affected when you connected in SSH, security, when you connected that problem is the security, when you have to go remove the security, then you connect it will be working properly, other we have check that your another mission is connected SSH, then secure copy, if you want to copy one mission to another mission, the time for using for SCP command, if you SCP on regressive that the source of the folder and destination of your missions, is the command for the SCP hyphen or for example, STC the folder and route for your remote missions, then IP address, but which folder you want to copy, temporary if you don't, if I not give anything, where we will go to store this home folders, okay, so add the bits and monitoring, if you know the file type directly give for the hyphen and file, what file you want, you can give that, it's automated displayed here, then list of file directory and disk space, if you know system, what are the file system is available in your hard disk, then you give for DF minus H, what are the mount file, what are the file is, system is available is display on the hyphen directly, so estimator file space on the usage, what is the use of estimator file space on the usage, anybody knows that, the DU minus hyphen for example, your copy to own mission to another mission, the file size is 2 GB, so when you copy the file, you want to see that file is copied or not, that can go to your directory, DU minus H and hyphen and temporary, you know the how many, how much the memory copied your missions, the file how many percentage is copied, see easy to understand that command, then check the memory of usage, free minus, what is the meaning of H, it is for the human readable, okay, so check the memory of usage, if you have the system memory, you can give directly for free minus M, your run speed, what are the things, what is the minus M, you have to tell me for the memory, you have to give for G and H, GB why you are telling that, M for MB, okay, check the all mounted file, you have to use the mom command, if you connected the extended hard disk or pen drive, whatever you want, you have to use the command, you can know that what are the system is mounted in your machines, okay, if you have for example, you connected the removal pen drive, that time the pen drive is not display on your machine, how we know that usd is connected or not, that time is for mount, you give for slash all, automatically is mounted on your machines, it is I think it's little bit use of your life, ITB networks, how you are connected your internet in lab or your hostel or somewhere, so there is two connection is available, LAN connection and the ITB wireless connection, if you want to use ITB wireless, there is two connection, if you want ITB wireless, there is a site cc.itbac.in, you have to go that, you have get all the information of the how to connect the ITB wireless under normal connection, you know you have the idea about how to how you know that IP address and all, for each and every lab there is separate IP address, for the DNS and all, then only knows you have to connect it, right, so first you want to connect it the ITB wireless, so most of these will be available for 7 and 8, 10, we have the exe file in available cc.itb.ac.in, okay, if you go there you have to download the file in the windows, just to installation, just to click on it's automatically installed, after installation I have the problem it's windows 7 or 10, I don't have connected the ITB wireless, so that time how we using for how you are using that, first you deleted the extension the Wi-Fi, for already how we installed the ITB wireless, just you have to delete it, how do you delete that, you have to go for the ITB, sorry Wi-Fi setting, then Wi-Fi setting go to manage and manage networks, it is display on the ITB wireless is just you deleted it, just forget it and all, once you deleted it you have to connect it the manually, just you go there open and sharing network in the windows, go manage wireless networks then manually created your profile name, the profile name you have to give for IATB-Wireless is for sensitive, if you change anything not able to connect, if everything is caps, W also caps and the other thing is small, if you type the IATB wireless name, then go to select the connection settings, select a security tab, now authentication how we choose for the PEAP, okay then how to change the setting of the remove the validate server of certificates, under configuration you have choose for EAP and MS tab, it is also available on cc.iatabac.in, you have to connect it, once you connected your IATB asking for the LDAP user ready and password, maybe they will give for your LDAP user ready, you can connect directly, for it is only for windows, if you for the linux you can go for directly on network setting, just you connect it, it will be working on 100%, so most 90 50% is not working on IATB wireless windows, you have to go for manual setting, so most probably everybody is saying I select their IATB wireless but I'm not able to connect the internet, what is the error I don't know, so you have to follow the steps, so proxy settings, there is two type, with proxy and without proxy, with I'm telling that first connection of the without proxy, once you connected it, you go for the browser, just type it internet.iatb.ac.in, I will see you asking for your LDAP user ready, once you type the LDAP user ready then only it is working, otherwise you not get the internet, the proxy setting. Another one for IP allocations, there is two type, only for academic section on hostel side, if you want to know the academic section that IP address is available on cc.iatb.ac.in, internet is slow, see it is like department IP address, otherwise you go for, if you want to particularly CAC department, want to the IP address detail, if you go the cac.iatb.ac.in, there is options available by floor ways, for the each lab which IP you want to know that how to click on that, for example I am the new CAC building allocation, the first floor, we click first floor, the class from via IP address we displayed for 101 IP address details, so you have to connect your system using the type P, you will give for the physical network, then you have any query related, you have to connect directly DBB sysad at cac.iatb.ac.in, otherwise sysad at cac.ac.in, you have the network related or system related, any queries you have to directly write them, they will immediately give the response, if you want anything related then go for cc, the website name is cc.iatb.ac.in, otherwise cac.iatb.ac.in, whatever everything is available on the both website and dog, if you want to download any software latest, okay, if you go ftp.iatp.ac.in, this site is available all the open source software, not for the open source and you have get it for that Microsoft academic softwares and dogs, but you need LDAP accounts, other thing open source everybody you get it for the ftp.iatb.ac.in, only not for that you have get it for the MATLAB, for example, if you are in mechanical you have get it for the AutoCAD related, every software is available with license also, you have to download within a time, within a second, because it is connected internet, so the speed is very high, so you do not want to wait for the internet download the speed on those, okay, thank you.
