Allowing Users To See Only Their Own Processes In FreeBSD
Jul 26, 2008
I ran a shell server on FreeBSD 4.x and was able through (if I recall...) a kernel option to allow users to only see their own processes. For example, if a user ran top it only showed their processes and no others.
I'm racking my brain trying to remember what I did to make that happen and I'm not having much luck with google.
Any other FreeBSD folks here that are familiar with this and care to remind me?
I think it's time I start keeping notes.

I am providing consultancy for a SOHO type of organization - 6-10 employees. The budget is not much for hosting. So we can't go high end. The current hosting company, in a way addresses more than 60% of the needs. However 1 important need is for users to be able to change their password for their email account. The current host says that DirectAdmin and CPanel fall short on this and nothing can be done. Any suggestions for hosts that address this need?
This is what the current package looks like:
* Directadmin control panel
* Apache web server
* Exim smtp server
* PHP5 scripting language
* PHPMyAdmin database control
* Unlimited subdomains
* SSI server side includes
* Centos linux OS
* Great uptime
* Squirrelmail web mail
* MySQL 5 database server
* PERL private CGI-BIN
* Unlimited domain pointers
* Webalizer statistics
* 1,000 megabytes of space
* 5,000 megabytes of transfer
* Unlimited POP3 and FTP
* Unlimited mySQL databases
* Unlimited sub domains

It's possible to allow certain IP ranges to access certain ports by adding to allow_hosts.rules, but is it possible to allow certain domain names?
Eg: I want to allow all users of bell.ca to access port 41125-41130, and block all others from inbound/outbound.

On my server, users can connect to any database as long as they have the database user and password. This makes it easier to hack any database on the server.
What I want to do is to make the users can only connect to their own databases and not other's.
I tried changing the localhost ip address but it didn't work ( I assume I didn't do it the right way)

I'm selling downloads of music files. The zip files are quite large. I've had several people complain that they get a message that the server resets their connection before the download finishes.
What can I do to allow these large downloads?
I'm on IIS.

I have a CentOS server running WHM/cPanel and have just had a recent problem pop up:
My SMTP server will only accept connections if the client has their SMTP settings set to use SSL. It won't accept regular, non-SSL connections. Ordinarily I'd welcome the added encryption, however, most of my users who rely on the SMTP server have their mail clients set not to use SSL.
Is this a setting somewhere? If so, can someone direct me as to where it would be, because I've been looking for hours and can't find a thing!

we've been with Softlayer for a little over a year. The service has been good but their support has been a nightmare for us. There was a time that we were under a dos attack and they refused to do anything about it which is what forced us to switch.
But that's not the reason I'm here. My billing ends on the 12th, their terms require you cancel the server 3 days before billing ends. I pay manually each month by pay pal. I tried to cancel the server today, what I assumed was 3 days before the 12th and they told me I couldn't do it. That I had to pay for another full month. So I told them I just won't pay and they threatened me with a late fee. Is there anything legally these people can actually do to me if I don't pay? All they have is my contact information, I don't think they could submit to collections over that without my social security number.

We're running a departmental intranet site on Apache 2.2 (on Windows Server 2003, if that matters). I'm trying to figure out how to post exe files on the web site so I can create a link and users can download the programs.trying various changes to my httpd.conf file, but no matter what I tried I get a 403 Forbidden error and the error.log file shows an error "Options ExecCGI is off in this directory:...".
1) I've tried putting the EXE in various folders.
2) I don't have a .htaccess file and I don't see anything in the httpd.conf file that seems to specifically relate to access for this file type.
3) If I put a zip file in the same folders, I am able to download or open it.
4) The httpd.conf file should be whatever was created when we installed Apache.

I am looking for a VPS hosting company that basically allows unlimited email sending without restrictions. Does it necessarily have to be off-shore?
I will be sending about 300k per day, or somewhere in that neighborhood.
The bandwidth and storage I am not too concerned about.

This is one of my thoughts and a valid one based on my own experience.
One of the problems with shared hosting account that comes with multiple domain/web hosting, is that all the hosted domains shared one single cpanel and one root directory where all the addon domains directories and files are all jammed up together with the maindomain's directories and files.
Notably is some php scripted sites running on addon domains were unable to function effectively. One such example is using imagevue - a photo slideshow/gallery script. The problem of no photos or photos unable to load/show when the site is called directly from the addon domain [url]
However, when accessed through the maindomain [url] it has no such problem and the photos showed up.
With the above incident and having tried on three other different webhosts, it's clear that something has to be done or otherwise, having multiple domain hosting has no real benefits if you consider the above matters.
As such, the only solution I can think of is to install whm on our shared hosting account so that we can have each added domain to have its own independent cpanel.
So long as we are not doing any reselling activities, there is no reason for the webhost to object or refused.
If your webhost is genuinely care about you and truly to provide an enhanced and efficient webhosting experience, then whm is one way to overcome any shortcomings from existing facility of using a single cpanel for all your multiple addon domains.
Of course, another alternative is to use subdomains from the main domain and redirect all your addon domain sites to the subdomains. That would really defeat the purpose of having addon domains in the first place. Also, why should we? since the hosting account is for multiple domain hosting.
Webhosts offering so-called unlimited domain hosting or limited multiple domain hosting on a single cpanel, should review the existing known issues such as the one mentioned above, and consider using whm to overcome such issues, thus truly provide a pleasant and effective multiple domain web hosting experience to its customers.
Webhosts should tweak and enhance its existing features/softwares/hardwares to improve the overall webhosting services.

When trying to make a subdomain on my main cpanel domain, through cpanel, it acts like it is making it, and adds the dns entry, but it does not work. All other domains work fine.
I submitted a ticket to buycpanel, they asked for the login information this morning, and have not heard back from them. This has happened every since they installed cpanel.
I am hoping its something simple that one of you knowledgeable people may know how to fix.

I am going to buy a godaddy wildcard subdomain SSL certificate. Basically I want the ability to enable and disable ssl on certain subdomains from cpanel. Basically I am going to charge customers extra for an SSL enabled subdomain.
Can I create an .htaccess file in the home folder of the subdomain which forces SSL or unforces/disables SSL? Maybe also do mod_rewrite so for example if they paid extra for ssl support:
[url] WOULD AUTO-REDIRECT TO [url]
Also if they didnt pay for SSL
[url] TO [url]

On a new server we have running CPanel, we have manually created a user account and when i try and log into mydomain.com/whm with that username/password it doesn't let me.
Now my second thought is that I should be logging into mydomain.com/cpanel rather than mydomain.com/whm but I get a 404 for /cpanel.
If i'm logged in as root, i cannot transfer into the user account cpanel either...

Recently I've upgraded my MySQL server. I connect to it via a conection from NIC to NIC (Internal IP addresses). Since the upgrade/format, I've managed to get everything back to the way it was. Everything works fine for 15-20 minutes. Then the PHP server can no longer access the MySQL server.
I tried logging in from the PHP server, I get access denied. I then tried logging in locally, on the MySQL server and I get in fine...
It's not like it's a firewall issue though, it's strange...
I tried updating PHP/MySQL to a few releases, even the RC's to no avail...
Something to note is that when I try restarting MySQL it can take 4-5 minutes, sometimes not even complete.

My server runs on CSF.
Very often the firewall automatically ban some of my customers IP who has fix IP to access to their webmail and website, because they have over 100 staffs, maybe that is why the IP was banned automatically for having too many connections to the server.
Everytime I unban the IP, it keeps being banned again. I have to stop / restart iptables to flush it.
How can I allow the IP permanently?

I just recently switched to using fcgid with cPanel and was wondering how I can go about seeing what is actually running under each process. Before when I was running PHP as CGI I could do psauxwe|grep PID and see all the environmental variables along with the path. I'm not able to do that any longer with fcgid. Is there anyway to get this info now?

Well one of my servers has been under a DDoS attack for a while and I've been doing things to keep it down but there is a suspicious process that keeps running and I am guessing that is whats keeping the server load up because when I stop apache the load goes down but not for long.
The process is this:
Code:
/opt/adobe/fms/fmscore -adaptor _defaultRoot_ -vhost _defaultVHost_ -app registry -inst registry -tag -conf /opt/adobe/fms/conf/Server.xml -name _defaultRoot_:_defaultVHost_:registry:registry:
Does anyone know what this process is or how to block it?

Problem:
Tasks: 580 total, 1 running, 579 sleeping, 0 stopped, 0 zombie
I keep getting too many sleeping processes (300-500) - making the load shoot to 20-50 within 30 minutes.
I stop apache, and restart it in 5 minutes, everythings fine.
Cycle repeats.
Where can I stop this? By editing the httpd.conf file?
Which setting would it be under?

On jaguarpc.com, their terms of service state,
"We do not allow programs to run continually in the background. This is to minimize system resources used and operational maintenance needed. We do not allow any chat or topsite programs on our servers other than the ones we pre-install for our clients to use. IRC: We currently DO NOT allow IRC or IRC bots to be operated on our network."
I thought the whole point of using a VPS was so you could run a continuous application (like a chat/game/etc server)? Why are so many VPS services against IRC (the chat server I use is not IRC based, but I just think its wierd so many prohibit IRC)

I'm having a problem with one user account, every 5-10 minutes a spamd process of this user gets locked using 60-90% cpu and never ends. If I don't kill the process another one does the same and they all get locked causing very high loads
I reinstalled exim but it did nothing
The problem persisted even when this user's account was suspended
