I would like my external drives to be readable and writable from Linux, Mac OS X and Windows.
FAT32 works, but the 4 GB file size limit is a showstopper these days. Are there any alternatives?
I know in the "old days" it was good practice to shut this off.
But nowadays I have heard that it improves deliverability of email. In the old days people were not worried about spam (or having their outbound email rejected), so that made sense.
Of course, the question is only relevant to servers that send email.
What is the current, common practice among discerning Linux admins? Run identd or leave it off?
Thanks

I use 2 connection to connect 2 client. 1st computer use LAN connection and 2nd use wireless connection. when i make new wireless connection in my ubuntu, the wireless that i make could not be detected by other computer that use wireless connection.i have tried to use windows and ubuntu as a client but it doesn't work.
Maybe there's someone who know about it.
Please share :)
If I create a new filesystem/directory off of / and I set the Linux permissions to 770 I expect the group to be able to read and write files in that directory. SELinux was preventing me from doing this until I changed the SELinux type on that directory to public_content_rw_t. If this is just a directory in which users in that group will share files is this an acceptable SELinux type or should I be using another one? Writing a custom policy seems like overkill for these purposes.
Thanks
if i write this command in linux "dd if=/dev/sda1 of=/dev/sda2" it copy the whole dev/sda partition bit by bit to dev/sdb.....is there any way in WINDOW that i can just only copy the contents of /dev/sda1 to /dev/sda2 and also the MBR and not the whole partition bit by bit......
I have problem to mount a compressed (ISZ) image under Linux, which was created by e.g. UltraISO? I am aware about user-space fuseiso, but it fails to mount these images, as I have reported in Debian bugtracker (correct me if I ddi something wrong). I ask the community for a help: I need a proved solution to mount these images without decompressing them.
I believe that CONFIG_ZISOFS kernel option cannot help, as it refers a special RockRidge extension (per-file compression with mkisofs -z or mkzftree).
Is it somehow possible to boot a Linux operating system from an encrypted filesystem/disk without having uesr interaction?
Background: I am preparing a VmWare Image for shipment to a customer. This image contains sensible data. The only access granted shall be via an apache server running from inside in the image.
Is there any way to get APT to install packages to my home directory?
I don't want to make changes system wide.
Alternatively, are there any home-directory based linux package managers?
I have Linux server running a unauthorized process (which I do not know the name of) which is doing a port scan from the server out to the internet.
How do I find out which process this is and kill it!
Thanks!
We run quite a few internal mailing lists with SmartList (procmail). I need to offer a web interaction ability (think Google Groups) to the mailing lists. Is there anything that will do this on top of SmartList?
If not, is there anything that will do this in general on another linux mailing list manager?
I need to periodically give temporary and limited access to various directories on a CentOS linux server that has vsftp installed.
I've created a user using useradd [user_name] and given them a password using passwd [password].
I've created a directory in /var/ftp and then I bind this to the directory that I wish to limit access to.
What else do I need to specifically do to ensure that when this user logs into FTP, they only have access to this directory please?
That I know:
In command line, use TAB to autocomplete the commands.
You need just to select a text to copy it, and use mouse middle button to paste.
Which other "untold" secrets Ubuntu hides?
obs. I don't know which of the items I told are for any Linux or Ubuntu specific.
I'm trying to install a newer version of libevent than is on my machine, so I can install memcached. However, the install for memcached complains that the libevent library isn't in /usr/lib64 and that it isn't 64bit.
What options do I need to pass to ./configure to get it to compile as 64bit and/or into the /usr/lib64 directory?
This is what I have at the moment:
CHOST="x86_64-pc-linux-gnu" CFLAGS="-O2" CXX=gcc CXXFLAGS="-O2" \
CC=gcc CXX=gcc \
./configure --prefix=/usr
Thanks!
I am trying to reset — or rather, install — a boot loader on my hard drive. I initially had a Linux distro installed, which I completely wiped out. Now, when I try to install Windows 7 from my USB, my machine says
Missing operating System
And when I don't boot with USB, it says
"bootmgr is missing"
So now I am wondering, how I can install a boot loader, so I can install Windows 7?
Im running a virtual linux server on a low-end system, and i wold like to configure the server to boot in terminal window and not to the Gnome log in window, this is because of the low specs on the hardware.
Hello,
in a Linux environment, I need to kill a process which has been started by user2 if I am user1 without being sudoers or using root.
Do you know if there is a way of setting that when launching the process? Such as a list of users allowed to kill the process?
Thanks
Within a minute of connecting to my remote Linux server through SSH, my session times out and I cannot contact the server until a few seconds have passed. Meanwhile, I'm connected to other servers without interruption. This is only happening when I establish connection from an hotel wireless AP. When I connect from my phone's Internet, the problem does not occur. Does anyone know what might be causing these unusual timeouts?
I want to change OpenJDK to SunJava in my ubuntu linux desktop , i have downloaded the "jdk-7.tar.gz" from sun's website, but there problem is how to make the system to use the newly downloaded java ? I tried adding the new jdk/bin/java to my PATH ( from .bashrc ) but that seem not to work (cause probably OpenJDK's path is inside my PATH variable as well , so the system checks that first)
Here's my JDK7 : /usr/lib/jdk7/bin/java
Here's what $(which java) outputs : /usr/bin/java
Thanks in advance
I'm using a Linux machine at work, and started using at home in a VM for some home development.
I have a vimrc and a bashrc with some configuration, that are useful for both machines.
What is the best way to sync them? Create a symlink for each file in my home folder pointing out to a the respectives files in my Dropbox sync folder? Is this possible (delete .bashrc and create a symlink instead)?
I can't seem to find any documentation on the subject. I'm working on putting together a linux install for a fairly "dirty" environment. Best practice there would be a statically compiled kernel with no module support. I can already do the customizations to strip out unnecessary drivers/etc to get the performance and disable module support. Does anyone have a link or any ideas on how to get the Oracle Virtualbox module (not the OSE one, I need USB passthrough) compiled in?
On a old machine (512 MB RAM) I am currently running ubuntu jaunty and firefox 3.0.15. I tried the ad blocker addon add block plus but it eats lots of RAM (300 MB).
Is high memory load of this add-on a bug, which is fixed in a newer version or just normal? If so, why is the memory usage so high?
Is there another ad blocker add-on for firefox or another browser- add-on combination for linux (ubuntu jaunty) which uses significant less RAM?
On one linux server (Gentoo hardened), we are experiencing bursts of the following messages in dmesg from time to time:
TCP: Treason uncloaked! Peer xx.xx.xxx.xxx:65039/80 shrinks window 4094157295:4094160199. Repaired.
Is there anything we should take care of or is this normal?
What is the ending 'r' for and the leading 'd' for in file permissions on Linux?
Example:
drwxr-xr-x
I know about the user, group, others part, and I know w=write, r=read, x=execute.
But I don't know about the leading 'd' and the trailing 'r'.
Care to explain?
Thanks
What I need to do is a program that given (as a command line argument) a directory with more directoreies inside, and 4 Pics inside of each dir, the program makes a thumbnail of the 4 files and glues them together (2 rows, 2 columns) and renames that image to the name of the directory.
I think it could be done with a combination of a program and shell scripting (I'm experienced in M$, but new to linux).
Some real examples would be great.
Thanx in advance
