Limiting Ssh User To Specific Folder
Jun 23, 2009
I may have this wrong, but I think it's possible. I have a friend who wants to run a process on one of my servers, now I don't particularly 'care' about this server, it's just used for a couple of unimportant things so I'm okay with him running it, but I don't want the hassle of sorting out things if he decides to delete everything, so I'm hoping it's possible to limit his directory.
For example, I have the folder "people" in the top most directory, inside that I have "arthur", I want to limit the ssh user "arthur" to the folder "arthur", I don't want him to be able to cd ../../ and delete stuff, is this possible?

I am interested in setup user activity limits to avoid peaks on the server load, I have readen a lot about PAM and limits.conf but still have no idea on how set this limits. Most of the examples are similar to this page http://www.seifried.org/lasg/users/ but they are still confusing to me
>> I would like to setup rules like this:
Customers may not use more than 2% CPU daily, 3% memory daily, run more than 10 simultaneous processes per user, allow any process to run for longer than 30 CPU seconds, run any process that consumes more than 20% of available CPU at any time, or run any process that consumes more than 16 MB of memory.

I was reading up a thread where hostgator cpanel servers seem to be limiting IO activity per user/account/domain. How can that be achieved?
Any special limitations on a per account basis that I am not aware of?

i've been researching this but can't seem to find a decent solution.
basically trying to limit the cpu usage of a single domain, or limit accesses per hour if that's possible?
i tried adding an entry in /etc/security/limits.conf which restricts numproc to 2 and then down to 1, but it doens't seem to make any impact on the load. load of the server drops from about 1.5-2 down to 0.02 when this single site is suspended, and i can't have it run wild.
ideally would like a message that says something along the lines of server is too busy... trying again in 5 seconds or something along those lines?

I thought I knew enough about my .htaccess stuff to do this, but I can't seem to work it out. What I want to do is if a user visits domain.com/folder, we check to see if the folder exists. If so, show as normal (IE domain.com/support)
If a user visits domain.com/dynamicusername (dynamicusername is not a physical folder), redirect to dynamicusername.domain.com

Is it possible to create an email forwarder that will forward to a specific folder?
For instance, an email to "anemail@domain.com" will forward to a folder 'fold1' of "realemail@domain.com".
Alternatively, is it possible to forward but with adding additional headers, such that I can then create a filter to place emails with that header in a specific mail folder?

I know about the general log but want to just log queries of a specific user. Our database does 400 queries/s on a slow day, so I think it would be a pain to grep though a huge log like that. And, im not sure if it would cause any preformance issues.

I need to create a subfolder under my domain name, and assign an ftp user to that folder. I want the user to only have access to that folder, is it possible? can you guys orient me, because I have no idea where to start, my hosting service provider is telling me I can only have one ftp account per domain, maybe I didn't explain correctly to my hosting provider.

I would like my Plesk users to each have access to the mail folder for their domain. cPanel appears to do this by default by creating a folder named /home/user/mail which contains a subfolder for each domain name. Plesk, however, places all email folders together in the /var/qmail/mailnames folder. I would like to end up with a structure similar to how cPanel does it, but it looks like there are at least a couple of ways to accomplish that and I'm not sure what would be the most safe, reliable way to do it.
One way I can think to do it would be to override the Plesk dovecot config by adding a new config file to /etc/dovecot/conf.d. I think changing the values for mail_home and mail_location as follows would possibly work.
Old values:
mail_home = /var/qmail/mailnames/%Ld/%Ln
mail_location = maildir:/var/qmail/mailnames/%Ld/%Ln/Maildir​
New values:
mail_home = /var/www/vhosts/%Ld/mail/%Ld/%Ln
mail_location = maildir:/var/www/vhosts/%Ld/mail/%Ld/%LnMaildir​
I see a potential issue with this solution; the %Ld for an add-on domain will probably be the add-on domain, and there will not be a folder within /vhosts/ with that name. Perhaps there is another variable for the primary domain that I could use there.
A second way I can think to do it would be to add a symlink in /var/www/vhosts/domain/ named "mail" that points to the actual mail folder for a domain. Again, issues would probably occur here with add-on domains, and I also can't see a way to automate this. I also predict permissions issues with this solution.
I am using Dovecot if that makes a difference.

how can i create directories in my (public_html / htdocs folder) that have disk space and traffic quota?
i activated the disk quota to the native linux file system and i tried to create a user but i could not put this user in any folder in the public_html (i dont know how to do this) also there is no option to create bandwidth quota..
one more detail is that the folders need to be protected with login and password because people may try to enter this folders (e.g. www.mydomain.com/protectedfolder)
all this using webmin or another free good script.

I have a vps at VPSVille, which I use for tunneling out onto the internet (behind a nazi firewall). Unfortunately, my vps keeps getting disabled because I cross the "20GB of traffic per month" allowed to any vps for tunneling - even though I have 300 GBs of bandwidth.
I'm now looking for another cheap vps host ($20/mo or less) that will let me utilize all the bandwidth I paid for.

I am just playing around with a server of mine, and I wanted to know is there anyway to limit the amount of inodes ( files and folders) a user can have? I am using cpanel/whm. Or is there a way I can receive an " alert" once a user has reached the specified limit?

I've recently hired a new server with the aim of offering FTP backups.
I have Plesk CP but I don't want to use that to create the accounts for these users - i want to use the Plesk license for webhosting customers.
My box is running CentOS with ProFTPd.
The problem i'm having, is locking down SSH access to the Backup customers - if i add an account using "useradd", it is enabled in ProFTPd as I want, and I have set ProFTPd to only allow access to their home dir. However, the users can still log in via SSH and have full access to the box. Ideally, I want to be able to remove these users from SSH access, or if that's not easily possible, not allow them to "cd" above their home dir.
I know it's possible to add their usernames to the SSHd config file under Deny, but is there a more elegant solution (bearing in mind i'm planning to have quite a few of these users)?

IP limiting on switch port.
Where a switch is set to only allow a specific IPs to be streamed from the servers connected to it.
Any server set with another IP even with a same C class range will be dropped or ignored.
eg.
Switch : with a set IP of 111.111.111.1 - 10
Any server that tries to set an IP of 111.111.111.11 and above will not get connected.
Currently I am using 3com SuperStack III 3250 switches. but after reading the manual and also searching on the net, I am a little lost on ideas....

On my VPS I would like to set the /tmp folder to 777 and point to it with session.save_path.
The VPS will host a number of sites, but I will have sole control of them. ie. the account holders will not have access to cpanel.
If it makes any difference, the server is running phpSUexec.
What are the risks involved with this?
