Which brand / model would you recommend for those:
1 - bw limiting on specific port (like 3mbits/sec on port4)
2 - creating vlans by ports (like vlan1 = port1 + port2)
3 - creating vlans by ips (like vlan1 =x.x.x.1 to 8, vlan2 = x.x.x.9 to 27)
4 - managing the switch from GUI
my linksys switch comes with a web control panel under "qos" where i can control bandwidth there is Ingress Rate Limit and Egress Shaping Rate, what are they?
View 6 Replies View RelatedThere are several big domains that frequently defer accepting mail from us causing long delays or rejections. Google, AOL, and Yahoo are examples. I'm considering trying the suggestions found in this online posting regarding rate limiting the sending of messages to those domains.

Would these changes be safe to make on a CentOS 6.4 server running Plesk 11.0.9 with Postfix 2.8.4? Would any special modifications for Plesk be necessary?
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....

What is a reasonable rate for ram upgrades?
I'm looking to upgrade the ram in my web server and was wondering what others have paid lately for the upgrade.
Going from 2 to 4GB.
I am seeing bqbackup transference rate when I use rsync very slow as:
18.72kB/s
I think this is very slow. What rate you have?
I've been collecting quotes from various colo providers for 1 full cabinet in Virginia. I've been surprised at how much power costs these days, but I also understand power is in short supply.
One quote I got raised a question though. For a Class C (non-portable) IP address space, they want $256/month (so I guess that's $1 per IP). Their other pricing seems in line with the other quotes I have received, but no other place wants to charge for IP addresses like that. Is $256/month for a Class C considered normal market rate?
Does that reflect their costs? Are they paying a price per month upstream for IPs?
I am hosted with ASmallOrange. I have always had fast uploads but recently that have been rather slow. 1-4kbs but now up to 20kbs. I think it depends on the file type. I am not sure.
This is starting to stress me out because it takes hours to upload 8 or 9 mbs of stuff.
What is a normal upload rate? How do I know if this is a problem with my host or with my connection?
I also upgraded to the lastest version of Cyberduck but I do not have OSX. I still have OS9. Could that be a problem?
When I try uploading a file of stuff it says 2 or 3kbs but when I upload an 11mb file it says 20kbs. It is so strange. I can't find a really good way to tract it. I am just watching the upload as it flickers and shows me a rate but it doesn't always. Deleting files is fast. And downloading normal files from the internet is about 144kbs.

Although I am looking at just geting the same MOBO and building it, there is not much of a price difference that I can see..
a sales told me i can buy two switch and do series connection,
then if one fail,another will continue to work,
it will take high HA,
but i still can not understand how to do it and work,
could you know what it is?
how much per mbps is the norm, assuming we're ordering 50+?
what about non-cogent?
Thanks to rising costs of energy we have received notices from GNAX that they are raising costs of power and colo space. Has anyone else seen similar notices from other colo's already ?
I know we have seen power rates increase the last few months in our homes, we talked about that here in another thread. It was envitable that colo facilities followed suit. How does this affect the other colos and providers?
How would you rate the following networks for transport and IP services:
Level3, Qwest, AT&T, Sprint, and Verizon
Please put them in order from you number one choice (best choice) to your number five choice (worst choice) if possible.

View 5 Replies View RelatedIs there a KB (I couldn't find one) - to implement rate limiting for receiving mail on our service nodes?
Just had another customer account compromised (not a very weak password either) - and that meant > 250,000 emails - a LOT of cleanup.
Not only do we need rate limiting, but we also need notification of potential abuses.
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?
View 3 Replies View RelatedI'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)?
bandwidth limiting on my home network, to some specified pc's, as they are taking up to much download bandwidth. Im leaning towards windows more but i am still unsure, would any one be able to guide me or give me a few tips on what type of program will do this, what operating system and maybe some tutorials if anyone knows any good ones?

For example;
Offering Unmetered national bandwidth and 10 GB international bandwidth.
OR
Offering 50 GB national bandwidth and 5 GB international bandwidth.
How would you go about doing this, tracking it, managing it, etc. Is there any software that does it already? For example Xen or Virtuozzo?
On an cPanel + RHEL 5.3 box at WHM - Tweak Settings, I activated "The maximum each domain can send out per hour (0 is unlimited)" and set that value to "300".
But, it seems that this limit is only if the user is sending using webmail or an email client, right now a joomla website is sending much more than 300 mails per hour, but it's using php to send the mails.
My question, how can I limit emails per hour on each domain while sending from php?
Code:
29457 username 20 0 29724 13m 5848 R 10.2 0.2 0:00.10 /usr/bin/php /home/username/public_html/index.php
We have Linux and windows shared hosting on our dedicated servers using Plesk are we are interested in putting in connection limits and bandwidth limiting in place but not sure what to use - we don't want to set them to be too restrictive but we don't want it to be free reign either.
I was wondering if anyone else was doing this, and if so what their levels were.
Additionally, does anyone use anything for IIS 6 on 2003 that supports bandwidth throttling of dynamic content? I know there are things for IIS 7 in 2008 but that doesn't help much
Is it possible to setup ftp accounts that have the ability for the users to view files on the server and upload their own files, but not download anything from the server? If so, how would this be done, if not, then as a 2nd option, do most hosting companies provide the option to disallow downloads on an ftp account if you need to do so, but allow uploads?
View 4 Replies View RelatedI've been searching a while for a box that I can throw in front of my servers that will basically look at inbound connections and if there are more than X amount of connections from IP:XXX it will block it for X minutes.
I thought a standard load balancer would do it, but according to Barracuda, their load balancers don't. They do DDOS prevention, but that's based on packet inspection. What I'm looking for is something that will block legitimate traffic when there's just been too much in a short amount of time. Basically I've got people using autosurfing programs and refreshers on my site and I'm getting tired of analyzing log files to find them.
Is there any way to set max MySQL queries per hour to all MySQL users at once?

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 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 have got 2 low budget dedicated servers from poundhost,I would like to find a way to limit their total monthly bandwith to 5TB so that I dont get past this limit even if the server stays for 1 day with blocked traffic or else! The one server is cent os 5 and the other is windows server.
