Switch With A Web Interface
Mar 31, 2007
I've got about a dozen servers on a single Linksys 224 switch but it only has the choice of 10/100 for port speeds. I need something that can actually limit thru-put per port in 1mbps increments and also has snmp.
The obvious choice would be a Cisco, but I don't like to toss technologies I know nothing about into the systems that pay my rent and I just don't have the time to learn IOS right now. I can deal with a Linux command line, but I haven't heard of any Linux-based switches. I also don't have any serial ports on my latest laptop so I'd actually prefer a web-based interface like the consumer stuff has.
Lastly, it has to have gig-e uplinks like my existing Linksys because I'm going to be jumping up to a 200mbps commit pretty soon.

This is my first post here and this sub-forum seems to be adequate for my question. If it is not, I apologize in advance.
I want to create a web application for an upcoming project of mine that has the potential to attract a large number of people. So the web application needs to be fast and secure at the same time.
I used PHP for minor projects for some time now, and although it is really efficient for quick web development, it _appears_ to me like a house of cards waiting to collapse. If you know how to use it properly, it can be acceptable, but there are still numerous security exploits in PHP itself that have surfaced over the last decade. Additionally, it tends to be quite slow and has a lot of bugs that aren't really security related, but can make your life hard. I've run test scripts (that I optimized for web deployment) on my own computer, and even on my own computer which is way faster (in terms of CPU speed, number of cores, RAM, and so on) than most servers, it runs slow--without any database access! And I honestly don't buy the "your server will spend most time in your database anyway, so don't worry about that" statements. I've tested it with databases that have millions of rows in them, and coded a test script that accesses the table and then calculates stuff from that and outputs it. If I comment out the database access the time needed to execute the script is only marginally reduced. I observed the same in my other projects. I also used Python and the problem seems to be the same.
Now, before the PHP/Python fanboy crowd yells at me: "Google uses Python and Wikipedia uses PHP, too". Yes, I know. But they have a lot of money to throw at the problem and can easily add new hardware if needed (Wikipedia alone has collected over 6m USD in the last year from donations). And a Wikipedia staff member I talked to some while ago told me that it's a miracle that Wikipedia is still running given that it is written in PHP with all its security problems (not my words).
So I thought: why not use a compiled language?
The obvious advantages would be that it is faster, and that I can leave out all the junk that is not needed in my case, thereby decreasing the chance of badly written code running in memory.
I have coded in C and C++ for a long time, including security-critical applications. So I absolutely know how hard it can be to write really secure applications, but I think it is also fair to say that I know how to minimize the risk of buffer overflows, validate user input properly, and so on. I often force myself to review my code some time later, in order to spot coding mistakes that you just won't see the first time. Additionally, I've created a neat string library around the standard library that makes string manipulation as easy as in PHP or Python.
So I continued my thinking: why not use C/C++ for your web applications and 'somehow' interface them with your web server?
And that's the problem--the 'somehow interface'. I don't know what to use that won't be deprecated in like 5-10 years from now. CGI seems to be quite okay, but I heard there's a huge overhead due to loading the executable into memory each time a user requests a page. FastCGI seems to be a better solution, but is not as widely supported.
My question is: What interface should I use if I want my web apps to be compiled? CGI, FastCGI, what else? The interface needs to be supported into the far future, it needs to be efficient and fast. And there's also one more important factor: time. Coding the application itself is an acceptable time loss, but if I can only run the app on a dedicated server and have to manage the whole server myself, this can become quite cumbersome. I'd really like to use a solution that can be run on a managed server.

I have a requirement where one of our partner is planning to connect to our datacenter using a dedicated leased line.
As per our partner, they will engage a Leased line vendor for this. This vendor will terminate the leased line ( Single mode fiber -- SC connector) to the Comm room of our Colocation provider.
I have next to nothing knowledge about fiber connectivity and have few questions in this regard.
Q1. If Single mode fiber is terminated at COLO's Comm room in form of SMF SC connector, what kind of cross connect should we request from COlo's comm room to our cabinet. ( SMF / MMF )
Q2. How are these cross connects terminated in cabinet? Do Colo provider use some kind of fiber patch panel or they simply provide a fiber link with SC/LC connectors at the end of it?
Q3. If cross connect needs to be SMF SC then which cisco routers support SMF SC interfaces? Do I need SC-LC patch cable?
(I looked at the various option but could only find the following GLC-LH-SM or GLC-ZX-SM for SMF connectivity. I read about these and found that GLC-LH-SM is used for terminating single mode fiber that spans up to 10 km and GLC-ZX-SM is used for terminating single mode fiber that spans up to 70 km in length. It looks as if both of these support LC connectors. Are these the only two SMF connectivity options? Do I need SC-LC patch cable )
Q4. Our partner only tells us that the terminated link will be terminated using SMF SC. How to figure out if GLC-LH-SM or GLC-ZX-SM is required.

I have 4 very low traffic websites hosted with Godaddy on a single hosting account. The thing is that I like their email interface and I totally hate cpanel webmail.
Godaddy webmail is pathetically slow these days and I am thinking of moving hosts. Is there any other webhost with a nice webmail interface such as GoDaddy's?

I got a VPS with Linode and I have installed CentOS 5.2 32-bit, Apache, MySQL and ProFTPd. The server itself runs very OK, however, I have issues with running 'chmod' on the user interface with either FileZilla or CuteFTP pro.
Whenever I try to chmod 777 on a directory, I got this error on the FTP client interface:
Quote:
Command:SITE CHMOD 777 includes
Response:550 CHMOD 777 includes: No such file or directory
Why no such file or directory? weird. It's just on the server though. The FTP user is the owner/group of the directory I try to chmod to.
But I am able to run chmod on Putty.

I currently use debian and have multiple (5+) ip address all assigned for a different purpose and usage. My issue is that i need the ability to accurately monitor the traffic being generated (and potentially graph via mrtg) additionally, I want the ability to enforce priority and restrictions per ip address.
Whilst on the subject I also have an openvpn setup which i want the ability to rate limit each user....
spend too much time trying to figure this out so now i'm asking for some help! More than happy to consider offers ($) for someone to do it for me...

I am setting up Vmware in a test server.
Did a ./vmware-config.pl and pressed enter for all the options.
I am seeing vmnet0 and vmnet8 in ifconfig result.
Now, the server has 16 IPs. Not even added to server. Just provided by DC..
I have created few nodes via vmware-web-console. The nodes are created without any issue.
Now..
I am not seeing any option in vmware-web-console to assign IP address to vmware nodes.
How do I assign my public interface IPs (provided by my DC) to every node?
I read someting about bridge networking.

I have a subscription and I'm able to switch the subscription to a given service-plan, but I'm unable to sync the subscription with the plan, using the CLI. These are my commands:
/usr/local/psa/bin/subscription --switch-subscription <domain.com> -service-plan Hosting
result => The subscription <domain.com> is now associated with the service plan Hosting..When watching the webinterface in Plesk, I see the domain is "connected" to the service plan, so far so good. However, I notice that the subscription is not synced.
Back to the CLI, I've tried some combinations, but I can't get the subscription synced. The webbased interface keeps telling me that the subscription is unsynced. Here is what I've tried:
/usr/local/psa/bin/subscription --sync-subscription <domain.com>
And I also unlocked it (just in case it was locked) like so: /usr/local/psa/bin/subscription --unlock-subscription <domain.com>
The funny part is that the CLI tells me: "Subscription <domain.com> was synchronized with the associated service plans." but unfortenately it's not if I look through the GUI. Only if I click the sync-option webbased the subscription get synced. we have to transfer over 1000 domains and need to sync these domains with a given service-plan.

I just installed Plesk 12 Web Admin Edition, installed and activated all licence keys and everything works fine.The only thing, I can't find the "Service Provider View" in the Interface Settings, there is only a "Power-User" view provided, even I've selected the Service Provider View during Plesk Setup, I was moved to the Power User view and now I can't switch the interface.I am really missing the server health monitoring from this Service Provider View like got it on all other servers I have.

I currently have a dedicated server, which is hosting several websites. I'm happy with the service I'm getting, but I'm trying to save money. I'm paying $120/month for the dedicated server. Spending half of that each month would be great.
Right now, the websites are either static websites, or are simple database driven websites with not much traffic. My server load averages are pretty close to 0.01
I would think a VPS would be fine for my needs. However, I may have a site I will host in the future that is database driven and uses Ruby on Rails. It would probably have 10-20 users online at any given time, and maybe several hundred subscribers total.
Would a VPS still work in this instance, or should I stick with a dedicated machine?

I'm sending off about 6 servers off to colo soon, and looking for a basic switch..
I would prefer it to be a Cisco switch (but doesnt have to be, just that i'm used to IOS), not used.
Fairly cheap and nothing overkill. Just going to be pushing 20Mbit/sec.
Must haves : vLan capabilities, SNMP, 10/100mbit upink, able to cap ports at non-standard rates (eg. 1mbit/11mbit).
