Keep Watch On Directory

Hello, I have an embedded linux device. I can connect to the device and I can upload or download files. No problem with this. But, at first connection, I want to connect to "/" directory instead of "/root". In the device file system, there are files ssh_config and sshd_config under /etc/ssh directory. I think I have to do something with these files but I don't know what.

I don't exactly know what mean "/root" and "/" directories. I think that the real root directory is "/" directory which is empty but when I connect with filezilla, the "/root" directory is the default so I had to go back to / directory everytime.

First time post so I hope it's not too long winded!

I've just installed Centos v7.1 and created an additional user.

First putty session I logged in with root and got the public fingerprint message and clicked Yes to accept.

However I noted when I logged in with the user other I did not get the prompt and my home directory didn't have a .ssh directory.

OK, so I created a .ssh (chmod 700) directory within /etc/skel and created a new user. Logged in with that account and still no prompt, although I do now have a .ssh directory generated.

I've tried deleting the known_hosts files in the root's .ssh directory and restarting the sshd daemon but it's not working.

How do I get it to prompt with original public key again?

Thanks for reading.

I am using scientific linux. In the directory user/project/Build, after I ran 'make' to compile and link all the cpp files,I had no problems. But then, when I went to directory user/run/run.sh, which runs the project binary in user/project/Build/bin/project, I get a segmentation fault error. In the directory user/run, I enter 'gdb' in the command prompt and get the message "*** No targets specified and no makefile found. Stop."

What am I supposed to do to detect the segmentation fault?

Hello Everyone! I'm somewhat new to linux, and getting my feet wet by building my first linux server.

So what i have is an application that moves/sorts files. Another program that catalogs them.

The problem is that each app uses it's own user. So my question is if there is any way that files owned by prog1user can be read by prog2user?

I have tried doing a chmod -R 755 Directory and that has allowed the second program to see the files, but I'm guessing this has certain security risks (although I'm not so worried about the files in this directory).

Anyways I was wondering if there was a proper way to do this? OS is debian wheezy.

Cheers!

I have a directory structure and files I wish to change permissions on, but I don't want to change permissions on every file/subfolder along the way. Example: I want to chown all files in dir4 where my directory struture is:
/dir1/dir2/dir3/dir4/*
However, both dir3 and dir4 are owned by root:root so I need to change the ownership on those directories as well. But, if I do:
chown -R user:group /dir1/dir2/dir3/dir4/
...it will indeed make dir4 and it's files accessible, but it doesn't change dir3 - so folks still can't get to the files they need. I thought about doing:
chown -R user:group /dir1/dir2/dir3*
... but that will give users access not only to dir4 and it's files, but any other files under dir3 which I don't want.

My work around has been to do a chown on /dir1/dir2/dir3 and then a second chown on /dir1/dir2/dir3/dir4/, but I am thinking there has to be a way to do what I want in a single chown command - right?

Changing umask value for files and directories take effect after reload:
/etc/profile
/etc/bashrc
default permission for all users:
-rw-r--r--
above permission is edited to:
-rw-rw-r--
If a specific user in group having only read permission to a file/directory is created before reload,and Linux server reloads, that user gets rw permission to that file/directory. what is the alternative of securing:
/etc/profile
/etc/bashrc
apart from giving the two files access to root user only, and locking out all other users?

Hi guys,
.
For no apparent actions from me, hidden folders and files show
in my /user/home directory, they are as follows:-

folders:
.adobe .cache .config .cups .filezilla .gimp-2.8 .gnupg .gphoto .gstreamer-0.10 .icedtea .java .local .macromedia .mozilla .pki .thumbnails

Files:
.bash_history .bashrc .esd_auth .ICEauthority

In my / directory
File: ./readahead

Seeking help to verify the above folder and files are not from a harmful source or application?

If they do not post any thread to the system, how can I conceal
these folders and files, so that they don't show up any more in
my home and / directory ?

Many thanks.

Hi everyone, I hope you're all well, I've made a pretty stupid error and I hope someone can help, thanks for your time.

So, I had been warned by gnome and my package manager that my HDD was full which didn't seem right so I decided to look at Gnome's 'Disk Usage Analyzer' which made the problem appear obvious. There was apparently a complete 1.5TB copy of my home directory in the /srv/nfs/ directory, now I don't have much use for NFS anymore and I needed to install some software so I thought the solution was quite straightforward , I cd'ed to /srv/nfs/ and rm -rf'ed the directory and figured that I would fix nfs at a later date. Now this seems to have deleted my actual home directory, which is completely empty and it looks to me like I've lost ~1.5TB of data.
So firstly, Is it actually this operation which deleted my home directory or did I manage to do this at some other point with some other command?
And secondly do I have any chance of recovering files? I tried to unmount the partition when I realised what I had done but I kept getting an error to the effect that the drive was busy at which point I rebooted and got the same error, so I unplugged the machine. Googling led me to extundelete but I don't have access to another linux machine at the moment, would this be my best chance?

Thanks again for any replies.

Dear Friends ,

I have more that 20 linux server running into my environment . It is very difficult for me to take system report like ( Disk usage, user session information etc) . So I want to prepare a centralized report on a linux server so that I can take the following report :

1) Disk usage (df -h)
2) Session Login/Logout report (lastlog/last)

Is there any available tool in linux to prepare it or give me a good idea to manage it .

Dear all,

This is long story cut short, with vsftp, if i set this parameters in the vsftp.conf file below

Code:

local_enable=YES
chroot_local_users=YES

I am able to login to the ftp account, see and list my home/user directory, and if i do a cd / or cd .. , i will still be chroot to my /home/user directory.

without, the need to chmod or or chown anything to my /home/user directory

=============================================

With openSSH, internal_sftp, even though I have set the sshd_conf to

Code:

Match user alankoh
X11Forwarding no
AllowTcpForwarding no
ForceCommand internal-sftp
ChrootDirectory /home/%u

I will need to change owner my /home/user directory to have root becomes it owner.
============================================

Q1) why this difference ? How does vsftp chroot without changing the /home/user folder ownership ?

Q2) i realize that openssh ChrootDirectory parameter causes my default login directory to be set as that of the parameter.
(e.g. if i set to "/whatever/xyz", i will be brought to that /whatever/xyz everytime i login to the sftp instead of my /home/user folder.

Why ? I thought that ChrootDirectory is just a security measure to specify the directory to go to in case the user cd to root (e.g. cd /), else not, i should still go to my /home/user folder everytime i login to sftp.

Noob
