Ubuntu Security :: Limit Login Attempts For Specific User?
Jan 15, 2011I'd like to limit login attempts for specific user. I've found information in manpages: [URL]but I'm not sure if this '@' is purposly there, so would be that correct?
Code:
aparaho - maxlogins 4
or
Code:
@aparaho - maxlogins 4
Maybe '@' is a group syntax? I'm confused.
What happens after 4 failed loggins? Is it enough to restart system to get another login attempts?
Are there any other values that it is reasonable to limit for safety reasons?
Server :: Limit The Suphp User Memory Limit?
May 12, 2010I have a VPS server with 512 MB memory. The php.ini is set so script memory limit = 16 MB. However, I have noticed in my top report, instances like the following:
Quote:
5484 coldclim 25 0 46476 32m 5920 R 0.0 6.4 0:00.93 php
The bold number of 6.4 is the % of sever memory this process is using. 6.4 % of 512 MB of memory is about 32 MB of memory, so it appears that this isn't being limited by php.ini. Am I correct? This leads to the next question: Is there some way to limit the amount of memory a single suphp process can use? (Basically, something like the setting in php.ini which limits suphp processes in the same way.)

View 4 Replies View RelatedGeneral :: Possible To Route All Mails Sent To A Mailbox To Another Server's Mailbox
Jan 1, 2011I have a Linux server that has local mail service. There are few user accounts on this server. User may send the mail to each other but that only restrict to LAN environment only.
For example, I may
# mail user1
To send mail to user1. User are not able to send mail to public. Some service like hylafax using this local mail service to send notification of fax status.
I don't want to manage and maintain local mail service anymore. I have subscribed a package from ISP to host a public domain of my own. I wish to have my hylafax service to able to send the notification mails to public mail server, is that possible to do it? It is great if all mails that send to local mail server may forward to public mail server. That makes the local mail service serve mail forward only.
Server :: Limit Print Job Size From Samba?
Mar 15, 2010Does anyone know of a way of limiting a print-job size from samba?
I know how to limit a print job size form cups, and how to require x amount of free space before accepting a job. I've even dug up how to require x amount of free space for samba to accept a print job, but I can't see how to limit samba to only certain sized jobs.
Someone tried to print a >1G file to my print-server this morning, causing me to have a less relaxed Monday than I had hoped. Because it ran out of space before spooling, it was never limited by cups. Because I had to get rid of it ASAP so people could get work done, I have no idea who's it was, or where it came from. Scouring logs didn't give me any good leads either.
Server :: Postfix Message Size Limit?
Sep 1, 2010I have been trying to increase the message_size_limit on my Debian 2.4.26 box with postfix 2.3.8. For example, I set message_size_limit and mailbox_size_limit to 104857600 (100m) and restart postfix. Running postconf -n confirms that it has changed. However when I send a test message it kicks it back saying the message size limit is 16777216 (16m, which is, incidentally, the default value of the berkeley_db_create_buffer_size parameter)

Dec 23, 2010I'm trying to limit access to port 8443 on our server to 2 specific IP addresses. For some reason, access is still being allowed even though I drop all packets that aren't from the named IP addresses. The default policy is ACCEPT on the INPUT chain and this is how we want to keep it for various reasons I wont get into here. Here's the output from iptables -vnL
[Code]...
Note the actual IP we are using is masked here with 123.123.123.123. Until I can get everything working properly, we're only allowing access from 1 IP instead of 2. We can add the other one once it all works right. I haven't worked with iptables very much. So I'm quite confused about why packets matching the DROP criteria are still being allowed.
General :: Limit On File Size - Doesn't Allow User To Create File Which Are Greater Than 100Kb
Jun 13, 2011I was just testing specifying limit on file size to a user and have added the following to /etc/security/limits.conf bob soft fsize 100 This basically should have said not to allow bob to create anyfile greater than 100Kb in size.
But the interesting thing is, if bob already has any file which is greater than 100Kb in size, it even doesn't allow to log him into the system both from console and SSH. Also nothing is logged in logs.. How do I configure it so that, bob can login to the system even though he has any file greater than 100Kb (but doesn't allow him to create file which are greater than 100Kb) ??

View 5 Replies View RelatedServer :: Limit User Processes ?
Feb 10, 2010I have some domains on a VPS server. Typical account memory usage for all domains runs at 50% of available, but I have a problem. One domain is causing me trouble because intermittently traffic will spike on that domain, causing so many requests within 1 min that I exceed my memory allocation for my entire VPS package. Apache is then killed but the virtualization software and Apache must then be restarted.
A sample snippet from tops right before the sever went down would like like this:
All of that memory usage adds up. I would like to "throttle" the number of processes that user/domain can run. I think this would be a quick and easy way to keep the domain from taking down my entire VPS. My understanding is that I could do this with the /etc/security/limits.conf file.
Is that correct?
I have never done this before. Do I want to set a hard or soft limit? I think if I wanted to limit the number of processes for "coldclim" to 15 I would add a line to limits.conf like this:
Code:
Assuming that is correct, can anyone tell me how the website would respond once it reached its limit? Would visitor queries become sluggish, or would the website not come up for them at all?

Networking :: In PPTP Server - Limit Bandwidth Per User & No. Of Connection Per Account?
Apr 2, 2010recently i rent a xen vps intended to setup a PPTPD vpn server for me and my friends. so we can by-pass the great firewall in china and get back on ....., facebook and stuff. i have already setup the server and i can connect to it without any problem. but i still want to do some further configuration the server:
1. i want to limit the bandwidth to 400k/s per connection.
2. i also want to limit the max connection per user a/c
i have some thoughts on the 2nd requirement. in the user configuration file of /etc/ppp/chap-secret, you can specify the range of ip the user can get, does it limit the max connection per user a/c? or they can connect anyway, just every now and then a box pop up says conflict in IP address?

Software :: CyrusIMAP: Move Mailbox Subfolders To Another Mailbox, Serverside?
May 26, 2011(We are running CyrusIMAP v2.3.16 on Slackware 13.1)The Problem:A user deleted a HUGE public Folder (>10000 Messages, >250 Subfolders), and now the Folder is in his "Trash" folder.Besides the obvious "Why did he have the access rights to do so in the first place??" question, I am honestly at a loss as to how the user did it:Trying to copy it back using Thunderbird failed utterly, TB crashes, or copies only a part, or nothing at all... (Tried 3.x on Windows and Linux Clients)So now I'm searching for a way to copy the folder back serverside.But web and manpages seem to offer few help:I don't want to move the folder to another partition, nor do I want to reconstruct or restore any corrupted data...All I want is to copy the folder from "user/USERNAME/Trash/HERE" back to "shared/archive/HERE".

Jun 9, 2010my system I want user1 and only user1 to be able to mount and unmount a specific partition, this partition contains backups and is usually mounted read only, needs to be temporarily mounted read/write by user1 while doing the backup.user1 is an unprivileged user. I've read that the user option will let any user mount the file-system (and only that user can then subsequently unmount it) and that the users option allows any user to mount or unmount the file-system.I also found this in mount's man pageQuote:The owner option is similar to the user option, with the restriction that the user must be the owner of the special file. This may be useful e.g. for /dev/fd if a login script makes the console user owner of this device. The group option is similar, with the restriction that the user must be member of the group of the special file.So it looks like I'd need a login script for that user to make the user owner of the device file (/dev/voiceserv/backup in this case)
