similar to: Limiting smbd process / active sessions of Samba server

Hi there, We are thinking about sharing same files: - OS2/Win clients with Samba - Linux clients with NFS. So, the same files would be shared by 2 different protocols. Looking at the open.c samba code, there seems to be no check / no error (sharing violation) returned to the smb client when the file is already locked by an NFS client. - So, even if a file is opened and locked by an NFS client,

Hello, Just wonder: is there any way in Dovecot to limit number of active IMAP/POP3 connections for a single user, not touching any other users? Basically, the situation is single user hammering servers by lots of POP3 connections from time to time, and limiting exactly one user could be good.

Hello Aki, Timo, Thanks a lot for your answers. I'll test with setting mail_max_userip_connections from DB first and tell if it works. If it does not, I'll go with the policy server. Again, thanks a lot. On 03.07.2017 9:29, Timo Sirainen wrote: > On 3 Jul 2017, at 9.24, Aki Tuomi <aki.tuomi at dovecot.fi> wrote: >> >> >> On 02.07.2017 10:53, Alexey Asemov

I'm probably looking for suggestions on tracing problems rather than a specific fix, since I don't see any links relevant to my problem. We have a Samba PDC with an ldap backend, serving about 100 active users and another 400 relatively inactive lab machines that connect once at the beginning of the day and possibly load a file or two from a network share. We have a problem where

Hi. It would be of utmost utility if there were a way to cause the sshd "banner" configuration setting to only print the banner in certain circumstances. What I'm actually after is avoiding printing out the banner for non-interactive sessions, so that if I run "ssh somehost ls" I don't get the login banner, but if I just type "ssh somehost" I do (at

yes! how to Limit the number of connection sessions allowed per Internet customer? We here in Lebanon,Beirut have some major ISP''s do it. ============================== by the way i put a question about an example using tcng/ingress on per customer basis and was not answered by any body. thanks. ( i am not pushing it)

Hello, I have a file server that serves files over rsync and scp (all over ssh - in fact, ssh is the only service listening) I would like to limit each user to no more than X concurrent ssh sessions (regardless of what they are doing (interactive login, scp, rsync, etc.)) I have read the documentation and man pages and it looks like I need to set this in /etc/pam.d/sshd, but I don't know

I just updated my cvs sources and recompiled now when any windows box logs in my smbd daemon goes crazy. I am enclosing the top command I just ran on the server as well as the output from ps. At this time only one windows box has logged in (it was win xp sp1). I have more daemons running than I would expect as well. -- top 20:51:22 up 1:23, 10 users, load average: 1.14, 3.40, 5.48 121

I can confirm setting mail_max_userip_connections from database in userdb query *does not* work at all. User can still open multiple connection above the limit, seems like it has no effect. I thoroughly checked DB response and it contains proper field name/value. I am using dovecot 2.2.31. Also, I have mail_max_userip_connections set globally in the dovecot configuration file and wonder if

LS, Spent a lot of this weekend reading about shaping and traffic control. The Howto is very extensive... :-) I hope to use this list to see if what I want is possible. The situation: - A central (big) Citrix cluster located in Frankfurt (all servers in one subnet) - The office in Rotterdam connected to Franfurt with a 2Mbit line - The office in Bergen (Norway) connected to *Rotterdam* with a

Hi All, Does anyone know of a way to limit the speed of *individual* TCP sessions, but without placing any overall bandwidth limits, and without requiring an explicit QoS entry for every ip address the machine is communicating with ? The scenario is a mailserver - say you want to limit individual TCP sessions (pop3, smtp etc) to no more than 512Kbit so that an individual session

Credentials are not changed - UID/GID/SID are still the same afterwards. The user is simply being added to another group.

Hi, We are using the following to manage sessions using memcache in our ruby app: use Rack::Session::Memcache, :key => "rack:session" I want to list the users who are currently logged in. Can you someone tell me how I can the sessions currently active? I could not find anything about it in the documentation. Also, how do set a "maximum session timeout" for these

Hi I was wondering if anyone else was having this problem or might know why its happening. I basically need to use AR sessions instead of the default pstore for sessions so I did the rake db:sessions:create to get the migrate file and then the rake db:migrate to create the session table. Also uncommented the below line in environment.rb config.action_controller.session_store =
