My server has 8GB RAM, however processes are limited to 3GB it seems, even if most of the memory is free (I have a mathematical program that mmaps lots of files and needs more than 3GB). I read somewhere that this is because the OS is 32-bit, but that it could be bypassed with "hugemem" kernel support.
I doubt that my host would install this for me, so how can I do this myself without breaking my server I've never done anything like alter a Linux kernel. My current OS is:
Linux 2.6.9-67.0.20.ELsmp #1 SMP Wed Jun 18 12:40:47 EDT 2008 i686 i686 i386 GNU/Linux With WHM 11.2.0, cPanel 11.11.0-S16999, REDHAT Enterprise 4 i686 - WHM X v3.1.0.
I am trying many OS's but none of them worked as it should:
- Windows 2000: install aborted - Windows XP: install aborted - CentOS 4.4: install OK but Kernel panic on start-up - CentOS 3.8: instal OK, only 3.8 Gb identified but the OS out of 8 Gb - CentOS 3.8 64 bits: couldn't install, CPUs support only 32 bits
Add to this, the machine boots on EL Kernel on CentOS 4.4 but not on the SMP Kernel!
how I could run this machine on Linux with 8 Gb RAM?
i dont want clients taking the servers I/O and server load over 4.00 when they do major update ect... querys on sql. is there a way to limit the ammount they can do?
I am going to run a VPS as a VPN proxy server and therefore I was asking myself if it is possible to freeze or shut down the VPS before it exceeds it bandwidth limit of 100GB a month?
I recently used these forums to help narrow my search for a reliable, competent host. I choose to avoid the larger hosts that sells unlimited or large amounts of disk space and bandwidth. I went with a smaller host that sells a 1GB disk space and 10GB bandwidth package that is reasonably priced. Keep in mind that my site is new and will likely only be visited by friends and family. I feel this package is appropriate for my needs.
Should I be concerned about a host that will suspend my site if I reach my limit? As a customer I would rather be notified to upgrade my account instead of having my site suspended. This practice of automatically suspending sites may very well be the normal procedure for most hosts thus the reason for my post today. Please share your opinions on this topic.
How do you limit CPU/RAM per account on a shared web server without virtualization? Something like what Dreamhost is now offering, for instance for user "john", assign 256MB of RAM and 10% of CPU. Without Virtuozzo and friends.
Im running the latest version of apache on my box and have 15 ip's on my box. Each ip goes to the site hosted on apache is there a way to limit it to one. Say for example i have these ips on my box 1.1.1.1 - 1.1.1.15
How do i select one of those ips to go to the site and have the rest not go anywhere.
im trying to run APF, but i am getting memory allocation faliures from iptables. I havent gone nuts on the rules just a simple firewall scheme for cPanel.
Is it possible to run APF with numiptent set to 250? Is this something the VPS provider will increase without problem?
How about if i can i trim the APF down such that all rules will fit in memory? I already disabled the list downloading (near the bottom of the file) and i get less memory errors but i still exceed my 250 limit.
Is there any option to limit users only to upload (No other permissions like permission change, directory access etc, only upload) in FTP.. I am using PureFTP..
I have seen options to do it in ProFTP, like below,
The server is temporarily unable to service your request due to the site owner reaching his/her bandwidth limit. Please try again later. Apache/2.2.11 (Unix) mod_ssl/2.2.11 OpenSSL/0.9.8e-fips-rhel5 mod_auth_passthrough/2.1 mod_bwlimited/1.4 FrontPage/5.0.2.2635 Server at confidentchemicals.com Port 80
Bandwidth limit gets reset every first of month but what to do when users reached to this limit between 1 to 10 days?
we don't want to upgrade users packages or bandwidth limit rather than allocated.
why can't we reduce bandwidth limit? __________________
