I've been giving the task to go to a Linux console as root. and generate a ssh rsa 4096bit key, and copy the private key to a USB drive.
1) What command should I use here? ssh-keygen -t rsa -b 4096 ?
2) Do I need to append the new private key to the authorized_users file? Which file exactly must be appended there? Would this be sufficient?
mkdir -p /home/myuser/.ssh
cat id_rsa_LOCAL.pub >> /home/myuser/.ssh/authorized_keys
Should any special permissions be applied to this file?
3) Which file must be sent to my usb drive so that I can take it home to connect with?

I have just been bothered by a fairly small issue for some time now. I am trying to search (using find -name) for some .jpg files recursively. This is a Redhat environment with bash.
I get this job done though I need to copy ALL of them and put them in a separate folder BUT I also need to keep the order intact after copying.
For e.g - If I get a JPG file under /home/usr/new/1/ then the destination also needs to be /test/old/new/1/.
At the moment, I am simply putting all files under /test/old/ and I can't somehow get the later /new/1/ folder path created under /test/old/
I understand this could well be done using while OR if else loop, though if someone can just guide me with a hint, I would be really grateful.
I will complete the rest of the steps and was asking here since I am still not comfortable with the shell/bash scripts yet and planning to be really good at it over the next couple of months.

I have a C-function that create a file and then make a copy in the same directory, but somethin is wrong with permission or owners.The program starts as root user.The file creates by the program:
-rwxrwxrwx 1 root staff 199680 Oct 18 10:58 test
Ok, but after copying the permission is not the same.The file after copying (with new name) by the program:
-rw-r--r-- 1 root root 199680 Oct 18 10:58 test_copy
I want to have full permission of the copy, how to do??

How to copy a Read-Only file in Linux and make the copy writable with a single cp command in Linux (Ubuntu 10.04)? The --no-preserve and --preserve seemed to be good candidates, except that they should "and" the mode flags, while what I am looking for is something that will "or" them (add +w mode).
More details: I have to import a repository from GIT to Perforce. I want that all Perforce depot files are Read-Only (that is how Perforce was designed), while all other files that were derived/copied from depot files are writable. Currently if a Makefile tries to copy a Read-Only file then the derived file will also be Read-only. This leads to build-errors when cp tries to overwrite Read-Only file second time. Of course the --force is a workaround here but then the derived file is also Read-Only. Also I do not want to mess with "chmod" after each "cp" command - I will do that only as the last resort.

have a script that will report whenever a file is copied? Some useful information would be the time/date, user, and destination whenever a file is copied. I've looked into the stat command, but it does not distinguish between copy and access.

I wanted to make a simple script that would trigger on certain environment events. For instance, I want the script to trigger whenever a new file gets copied or placed on the Desktop, and cut that file and place it somewhere else. Sort of cleaning the Desktop process. Here's the thing: I want to trigger on it's own, not requiring me to open shell and invoke it from there

I'm sure that the issue I'm having is easily solvable once I gain some understanding about copying files - and file permissions in Ubuntu. Here's my situation:
I have an external HDD where I like to back up some files (I mess around with distros on my main machine and feel less stressed knowing the important stuff is backed up). I have an ext4 partition on the external drive where I have copied files, both through the terminal (cp 'filename' /dev/sdc3) and by drag and drop (gnome-terminal).
The problem is, once the files are copied, most are inaccessible. I can view them, but some directories and individual files say I do not have permission to open them. Others are accessible. This is from the same user profile that copied them.
How do I see what's going on? More importantly, how do I make files on external drives available to any user or OS (that can handle ext4)? I want to make sure that if my whole system gets effed that I could still do a reinstall of my OS and then access those backup files.

I have a .txt-file with ~50.000 lines of numbers, generated by a mathematics program. From this file, I need line ~ 1.100 to line ~16.000 (these lines are always the same btw, this may make the solution easier, dunno) to be copy/pasted to another file, where the lines ~500 to ~15.000 (also, every time the same) should be overwritten by the aforementioned lines...I haven't found or come up with anything that works yet, mostly I find solutions to copy everything from one file to another but I can't find something to specifically overwrite a part of a file with part of another.

There is this bug in the latest version of Ubuntu, which is also Jessie, which is:
Can't copy a file from SMB share to the local file system: Software caused connection abort
The problem, apparently, is that newer versions of Samba hit servers with multiple requests at the same time, and for some reason the Zyxel and Iomega boxes can't handle this. The best solution they've come up with is to modify the smb.conf file on your server to include this setting: "max mux = 1".
Here is the reference material on this bug: [URL] ....
People who develop samba have fixed it in the latest version but neither the ubuntu nor Debian have released the fixed version of nautilus, as of yet. Here, is the reference: [URL] ....

we have two work computers, one with windows and one with Ubuntu. We are going to change the windows computer to Ubuntu, and put them on a network. So we copied all of the documents on the windows computer to the Ubuntu computer as a first step. The problem is, with the documents and folders that we copied, if they have spanish accents we can't open them.I tried looking on the forum but I didn't find anything about exactly that problem. One post suggested that the "locale" might be the problem, but our locale seems to be the correct one for our country and language.
The accents show up as white question marks inside a black diamond. If I open a file inside a folder with an accent, or a file with an accent, it tells me that the file doesn't exist.But when I change the name of the containing folder or the file, and replace the question marks with accents, I can open the folders and files.But we have lots and lots of documents, and it would take a really long time to change the name of all of the folders and files. How can I fix all of them at the same time?

Some time back using this computer a SucKit rootkit was found. Having dd urandomed the drive, flattened CMOS battery, flashed BIOS, run Knoppix live CD 6.1,using no flat pack battery (laptop), and memtested the RAM, I am still having problems with what I suspect is a javascript file that tries to reload the rootkit from? firmware. I suspect the firmware as everything else should have eradicated it??
Also it or a hacker via a backdoor then corrupts the drivers so devices malfunction. Windows security programs and rootkit detectors don't seem to pick it up. Fresh install of Windows or linux after the above still show this problem, though internet not used. The person who admitted rootkitting this machine is capable of writing java programs or using javascripts to do all this.
When viewed using Ubuntu 8.4 files and dates on a Windows partition appear normal both in file manager and terminal. However booting using Knoppix CD these files are all green, and I cannot change their permissions, even as root. ie: everything is green including text files etc. If I copy them to a linux partition, I can change their permissions and make them nonexecutable and nonwritable. Also on the Windows FAT32 partition the . directory has the date 1 Jan 1970.
If I disable any green files, I can shutdown and reboot cleanly. If I don't I start having problems shutting down [/usr/sbin/init ?] And always these follow a pattern:
Can't remember details as I have now corralled the beast but error messages relating to:
nfs-server
inet.d/statd
are the start of these.

When i do cp filename destinationfolder it isn't happening. I don't get any error messages or any indication that the file copy didn't happen. But when I go to the destination folder and do ls; the file(s) not there. I tried it with sudo also and i get the same results. When I first did the copy it actually copied it somwhere but not where i wanted it. It copied it to folder name Desktop. So i tried copying it from Desktop and again same results.

I'm using ubuntu and I'm trying to copy a .iso file to a dvd. I have k3b at my disposal. My problem is that the dvd is not empty, and I'd like to overwrite it or wipe it before copying the new .iso, but k3b displays an error if I try to overwrite it, it says it doesn't have the necessary rights and proposes me to use k3bsetup. I have it too, but I don't know how to use it.

I am developing a Web-based application and have some folders that will generally reside outside of the Web accessible area of the server. However, since some people will not be able to store those folders outside of the "public_html" folder, I am looking to put a blank "index.php" inside of every folder within that section of the application. To make things easier, I would like to know if there might be a way to recursively copy one file into every folder in a certain location.
In other words, is there a command that might do something like:
Code:
> cp -R index.php /home/user/public_html/source-files/*
Basically, I want every directory inside of "source-files" to get a copy of "index.php". The directory hierarchy within "source-files" can go at least three or four levels deep, so the command would need to be recursive. I am looking for a command-line statement that I can type to perform this action.

Firstly, I did perform a search on this problem in these forums, but didn't quite get what I was looking for. So I hope I don't yelled at for making a duplicate post. So I used rsync to backup my webroot to another nix machine. du -hs gave me 1.3 G on the source machine and 1.1 G on the backup machine. I tried to compare the individual files and noticed a trend. The files on backup machine were always smaller than the files on source machine. The source uses SATA drive, destination uses IDE. So this time I rsynced locally to another folder on the source machine. Same size anomaly. So i did a simple cp file ~/file and same size anomaly. So it's not a rsync issue.
I took a file and ran md5sum on both, the source file and destination file. To my surprise, even though the file size was different, they had the same md5sum. Now, let it be known that the source machine is a production server and the dir i rsynced was being used, serving pages to the web. I googled about this and came up with stuff like open descriptors and holes. I don't understand this stuff and was wondering if this was really the case. What are those if it is the case? And my backup copy is 100% identical right? There are thousands of files and I ran md5sum only on couple. Can I take comfort that when time comes, I can restore using my backup without any problems?

I am currently using debian 6.0 .While moving the file , electricity vanished. It happened that the file being moved wasn't at source neither destination folder.Is there a file copy program which works atomically (like teracopy in windows) .Yeah , common sense would be to manually copy then delete file from source . Can't this be integrated into GUI by a program?
