General :: Accidentally Type Concatenate Large File On Remote System
May 6, 2010
Every once in a while on a computer I'm ssh'd into, I will accidentally type "cat largefile.txt" and my screen will start rushing with text for the next 10 minutes. I'm always working in a screen session, so my current solution is to just log out and then log back in, and since it can go 100X faster when I'm logged out, it'll finish in the short time it takes me to type my password in again. Is there a better way? Either involving the fact I'm in a screen session? Or a way to do this within SSH? What doesn't work: detaching from the screen session (doesn't respond until file is done outputting) trying command to move to a different window in the screen session (also doesn't respond) typing ctrl+C to kill cat command (also doesn't respond, probably because the command is done and the buffers just have to catch up).

In my system around 73gb(pc-desktop) i have,1 primary partition(windows)-25gb, 1-extended partition(remaining gb) 3 logical partitions were there in (under) extended partition in one of the logical partition is d:drive. in my hard disk d: drive is -/dev/sda5
previosly i was fat -file system , (d:drive-/dev/sda5), i remember i changed the d: drive(d:drive-/dev/sda5) file system to ext4file system ,with following command using terminal
After doing(changing the file system)this one ,i couldnt see the d:drive data
By doing that
1q) Did i reformatted the partition? i think the new filesystem(ext4) has no knowledge of the data that was on it when it had a FAT filesystem.
2q) How to do undo operation,i tried to change the filesystem type to fat/ntfs in terminal using command --sudo mkfs -t FAT /dev/sda5.
Result:its showing text message-'mkfs.FAT: No such file or directory'(not in single quote)
I had very imp data in d:drive

I am supposed to take some small files, and print them to a specific printer, such that the small files are concatenated into one file. The file name has to be included in the file that gets printed.
Should I be looking to concatenate the files into one file with the file names included, and then print them?
something like: -printfunction -printername < file*

I had only Arch on an HDD.sda2 was "/".Now it's with Windows XP and sda2 is not a root any more but a container partition wich has sda{5,6,7} in it. I configured the dual boot and it works. It finds Arch and boots it, but not completely. Stops after some time and says: unable to determine the file system type of /dev/sda2. FSTAB is configured, sda{5,6,7} are on their places. So I can't boot Arch. XP boots correctly. What do I do with this error?Also it says: try adding rootfstype=your_filesystem_type to kernel command line.

How well is the ext4 new file system mounting compatibility with the older ext3 previous Linux installations ? I refer to Ubuntu 9.04 and the new Fedora 11 which have the option to install with the ext4 file format. Will it be better if I install with the older ext3, so that I will be able to mount all other Linux from each other in a multi-boot system ?

We have 2 servers, 1 is the webserver and the other is the Mysql server.
When transfering a 2GB file from the webserver to the Mysql server.
The webserver's connection to the mysql DB server dies completely.
Need to restart the MYSQL process in order for it to come back online.
During this connection downtime, when using phpmyadmin on the mysql server shows no problem running queries etc.

Is there a file system that both Mac OSX 10.5 and linux can read/write for large files (like 4gb files)? My desktop is Ubuntu and I run most from there, but I want to back up my MacBook and linux box on the same external hard drive. Seems there are some (paid) apps for Mac that will mount NTFS but I'm wondering if there is just a shared files ystem that will work for both.

I have created a new file system (fuse) which works fine and is mounted in the local host. I want to be able to mount it from another host. I added it to /ect/exports: /mnt/ltfs *(rw,sync) And restarted nfs. Then from my client host I type:
mount -t nfs myHostName:/mnt/ltfs /mnt/data1
Where /mnt/ltfs is on my local host and /mnt/data1 is on the client host. Note that this is a "FUSE" file system so here is it's local "mount" output: ltfs on /mnt/ltfs type fuse (rw,nosuid,nodev,default_permissions,allow_other) Note thet this is of type "ltfs" but I am told that it should work like its a nfs. ltfs uses fuse under the covers.

I am having a bit of a problem with my Ubuntu Server 10.04 install. I think it might be a kernel problem. Basically, what happens is when I copy a large file (a 160GB disk image) to my drive (>60GB) the system consistently crashes after about 60GB of the file is transferred. It doesn't matter if I am sending the file using cifs, or over SSH. Checking syslog (paste dump here), it seems these flush errors always appear shortly before the crash occurs. The destination filesystem is a hardware RAID 10 array with 2TB of space. It is formatted as EXT4.

I am ssh'ing into a remote server and then su'ing to root.The problem is that sometimes, I have not paid enough attention to the console message, and I have accidentally typed in the root password at the command prompt (when for example, I had failed to provide the root password correctly the first time - so su prompt went away).
I remember reading somewhere that a history of commands typed at the console is kept somewhere.I have 3 sub questions
Where (which folder) is the file stored?
Can I edit that file and remove the root password from it?
Being the paranoid person that I am, I wonder if there is a more secure way of logging into my server - other than ssh (or am I being TOO paranoid?)
My server is running a headless Ubuntu 10.0.4

I know that ImageMagick's convert program can be used as follows to convert a collection of images -- say, in PNG format -- to a PDF file:
convert *png output.pdf
The problem with this is that each image is then stretched to fit on one page, whereas I would like to keep the original dimensions of the images and put as many as possible on one page in the PDF file before moving on to another page.

When I run 'parted' and then type 'print' to see the partitions that are available, I see two entries: /dev/sda1 and /dev/sda2. /dev/sda1 is of ext3 type whereas for /dev/sda2 nothing is specified for file system type. The LVM flags are set for /dev/sda2.
When I tried to resize /dev/sda2, it gives me the error "File system type not recognized". let me know how to find out the file system type of the partition.

I use Markdown to store all of my source documents. Unfortunately, the .md extension maps to application/x-genesis-rom under Ubuntu. I'm not sure why that would be a system default MIME type, but I'd like to change it.
I've tried using:
Code:
gksu assogiate
to modify my file type cache. Unfortunately, even as the SU, I can't modify the entry for this file type. The "Remove" button is inactivated for the entry. (See attachment.)
How can I get rid of this (obsolete?) file association? Alternatively, how can I make my new one (text/x-markdown) take precedence?

Title sums up my problem. Im running so many processes in Slackware, running KDE. I dont even run that many programs, and already its more than XP has (by a **** load). What is wrong here, and how do i kill a lot of the processes to cut down on my cpu usage by tons and cut down memory usage while still keeping everything the same?
Heres a picture of my system monitor - img651 DOT imageshack DOT us/img651/5994/systemmonitorz.png
I didnt put image tags because its a fullscreen.
The memory rises over time, when I restarted my computer it was up to 500 - 600 mbps. At the minute after its at 360.

I need to send large files from a Linux machine to another using cryptography. The sender machine knows the recipient IP but not vice-versa. I don't need strong cryptography and prefer higher-speed less-secure solutions.
There are no problems with presharing crypto keys but I'd prefer not dealing with SSH users creation.
I think to HTTP PUT over TLS, but I never had experience with it and I prefer to hear which are the possible solutions. I know that it can listen as a daemon but I don't know anything about cryptography. So pipeing with OpenSSL may be a solution.
