I run a linux file server for my office and we user SFTP for remote partners to login and download files. Is there a way to see if there are any active connections or logins so I can know when it is safe to perform maintenance on the machine?
Since the machine is almost constantly serving large files, scheduled maintenance is often bumped off due to someone either upload
i have a vsftpd server running well but i want to make/force all users to use sftp and not just ftp is this possible?
View 1 Replies View RelatedI need to figure out a bash command to list all users logged in at or after 5pm - 5pm being the specifier in the command.
Code:
Command seems to be the easiest way to display users but it specifies all users log times.
I've also fiddled with the lastlog command to no avail.
Which commands do you use to output the current users logged into the system and accessing a specific file?
View 5 Replies View RelatedI want to make a webserver with multiple users allowed to login through SFTP to a specific folder, www.Multiple users are added, lets say user1 and user2, and all of them belonging to the www-data group. The www directory has an owner www-data and a group www-data.
I have used chmod -R 775 on the www folder, but after I try to create a folder test through my SFTP server (using Filezilla) the group of the directory created has only r and x permissions, and I am not able to log in with the second user user2 and create a directory within www/test due to a lack of w permission to the group.
I also tried using chmod 2775 on www directory, but without luck. Can somebody explain to me, how can I make it so that a newly created directory inherits the root directory group permissions?
Is there any gnome tool out there that will allow admins to talk with logged in users? Without it being amsn, skype, or gtalk... I'm looking for something like the 'talk' command but GUI based.
View 1 Replies View RelatedWhenever I want to shut down, I have to enter my password, because shutting down while other users are logged in is a privileged operation. Now, I couldn't download an update because the update lock was in use. I'd be surprised if someone had targeted my system, especially because I didn't install any obscure .debs or anything recently, but I'd really like to find out if it's been compromised somehow. Say, by obtaining an overview of all users currently logged into my system or something. Is that possible?

View 5 Replies View RelatedI try to write a script which would kill processes of users who are not logged in. My approach is to find out what users are logged in and then kill processes of all nonsystem users who fail the test of being logged. I use `w` for finding all logged in users, but apparently there are users on the list which `w` gives me who own absolutely no process in the output of `ps aux`. How do I log off those users, since killing their processes wont work (since they own no processes)?
View 4 Replies View RelatedI installed a few media servers to stream something to my PS3 over the weekend, but now when trying to shutdown the computer, I'm asked to authenticate with a password since other users are still logged in. I installed quite a few programs over the weekend trying to get it to work, so I can't remove a specific one. Is there a way to see which daemons are logged in under a different session? Found it.

View 3 Replies View RelatedI have 2 servers, web server & mail server. they show 2 users in the summary area when I run w or top commands. But the actual list of users logged in (using either w or who) shows only 1 user.
ps -ef |grep username only shows my current login as a running sshd process.
So I can find no trace of this other user except in the summary line for w or top. I have no shells or other logins left running elsewhere or abruptly terminated, no gui sessions (these are servers), no tty logins. Do I have another user logged in? Has someone hacked me & covered up most of their trail? Why do these commands show 2 users when everything else points to 1 user?
I read the log
Code:
I found this print out:
Code:
The line in bold is the security issue. There is only 1 user account on the system. There should only be 1 user logged in, not 2 users logged in. The remainder of the log file lists 1 user logged in, for similar log output. 2 users logged in does not appear again in the log file.
Does the second line of bold indicate that an attempt was made to log in to the system using SSH?
There was an internet connection interruption (no service) around the time of the log file event. The service did return, later.
Does that line indicate that an unauthorized user logged in to the system?
If there is a simple way to prevent accidental shutdown when the following situation occurs:
Sometimes, I log in on my father's computer to run some administrations' tasks (updates...). For that, I use SSH since I'm frequently far from my parents and what I want is to prevent a shutdown run by my father. Of course, he should be able to turn off by himself if nobody else is connected.
Molly-Guard allows to prevent distant shutdown, my request is a kind of complementary software.
Does anyone know a project which could fit with this request? Do you have simple ideas to write a short code I know bash, perl, python...
Just noticed this, when I am logged into OpenSuse 11.3 under my default user (autologin) I have 3 of the same user logged in, eg when I run top it shows 3 users and when I run the users command it shows the same user 3 times. Is there any reason for this? Do I need to investigate this at all?

When I'm logged into my account, I can't shut down the computer if someone else is also logged in unless I supply the root password. However, if I log out, I can shut down from GDM without being challenged, even though another person is logged in, which could cause problems if that person is in the middle of some work. Is there a way to password-protect the gdm shutdown function if people are logged in?

View 3 Replies View RelatedIt is possible to check who logged in with "who" command. If we are also logged in to that linux pc.
But, is there any possibility to check without our login?(not even by ssh)
Our logging in to find that pc, will be wasting the cpu resources. And may disturb the user who is working on the x-session.
I have an ftp server and normal login works fine as well as ftps but for some reason sftp sends all my accounts to the root directory of the entire server (not good). Been searching around but can't find a fix.
View 6 Replies View RelatedUsing CentOS 5.5. I have a handful of users that I need to have connect to my server via sftp and start in the same directory. for example, user1, user2, user3, etc.. will connect via sftp and upon connection will all be in the /some/dir/path/ftp-root directory.I know one way is to create these users all with the same 'home' directory, since by default a user starts in their home directory when connecting via sftp, but before just doing that, I wanted to find out if that is really the appropriate method to use? alternatives? Is there some setting on the sftp server end that could direct all users to one starting directory so that these users don't have to have the same 'home' dir? I'm using the sshd daemon that comes with CentOS 5.5 (with all current updates/patches)

View 1 Replies View RelatedHave recently setup Samba on a fresh install of Fedora 14 so that I can use it as a workstation in a Windows 2003 (win2k3) domain.
The install of Samba seems to have worked as I can connect to the Domain using ADS and kerberos. selinux and firewall have been disabled until I have it working 100%
The problem lies when i try to login to Gnome or TTY. It begins to create the home directory for the domain user logging in but after a certain process Fedora logs the user out of the system.
Have looked through several log files (/var/log/messages, log.winbindd, log.winbindd-dc-connect) but am unable to debug it any further.
Have posted the config files below which shows the Fedora machine is successfully connected to the domain as it lists its groups, users and validates logon credentials - it just won't logon!
Where i can go about debugging. Also if you need additional configs.
I have configured rssh 2.3 with openssh 5.8 on RHEL 5.6 64 bit to restrict the users to scp and sftp. When i try to sftp or scp it gives error connection closed. After long googling tried different solutions like add missing libraries, setuid to rssh_helper. I had full copy of /lib to /chroot/lib and /chroot/lib64 but no success. conf and log files are below for reference.
