I just picked up a Summit 24e3 and found it that the extremeware inside has no SSH (OMG) and Web interface. I am wondering if anybody got a firmware laying around that I may able to download off.

I have been trying to look for the damn thing everywhere and I can't find anywhere that has it either apart from extreme support of course which they want my life out of me.
I am after a good extreme 24e3 firmware that supports SSH and Web GUI since mine one for some reasons do not have that feature.
I have around 20 bucks (not alot i know but hey that all i got in my paypal)
Having a slight problem working with one of our Extreme Summit 48 (ugh) switches - I've figured out most of the basics, but I can't seem to find any way to add a secondary IP address to a VLAN! This, I would have thought, would be a pretty basic feature to have. Typing "config vlan [vlanname] ipaddress 1.2.3.4/24" works for setting the primary IP, but I can't figure out how to add any more - and doing the command again just overwrites the first one.
So... does anyone have any tricks up their sleeve, or is this something that Extreme neglected to add to this model switch?
Anyone using an Extreme Networks Summit x450a for aggregation/edge? I'm looking for a switch to handle aggregating a few racks (~10) and provide bandwidth accounting, rate limiting, and port filtering by IP address (not port). Any reviews?
View 0 Replies View RelatedLooking to upgrade to a new switch and have the following in mind. Budget is around 1-2k. We're pushing 500mbps upstream so i want to make sure that the unit can handle that well. Lots of full speed traffic between servers too.
No fancy features required, and the only need is port trunking, which all of these have.
I look at the specs for latency and pps, but I'm not sure if you can trust these figures.
Anyone have experience with the following.
HP Procurve 2910al-24
$1430
latency <2.9us
131 Mpps
176 Gbps
Bonus: 10Gb capability with expansion module
Extreme Networks Summit x350
$1300
latency < ?
65 Mpps
88 Gbps
Bonus: 10Gb capability with expansion module
Juniper Juniper EX3200-24T
$1800
latency < ?

88Gbps
Bonus: 10Gb capability with expansion module
Bonus: 8 ports are POE
Netgear GS724AT
$350

48Gbps
Can anyone suggest which one to go with?
View 5 Replies View RelatedI had the chance to work with the summit24 switches, and I personally liked them. It is straight-forward in my opinion for the Web Interface compared to others I have seen and the pricing seems to be reasonable.
I was wondering if anyone has had any experience with any of their switching devices.
if anybody know the cable pin out on making a console cable using those serial adapters?

I work for a company with a highly trafficked site (about 100,000 unique daily visitors). We have our "MANAGED" hosting through Rackspace for quite the pretty penny per month. It includes a dedicated back end / DB server and cloud servers for the front end.
The setup has been functioning perfect for 10 months now; but this past Monday the speed of the site immediately dropped. Page load times fell from 1-2 seconds to between 10-20 seconds, and sometimes not at all. As far as we know (and as far as Rackspace says), no server setting were modified. No new code was introduced on our end. It's a mainly static site, with minimal user interaction with the backend at all.
We've monitored the traffic, checked IPs, etc. We've even tunes down several site features in the interest of reducing server load. Upon a server reboot, the active threads/processes running on it IMMEDIATELY jump back up to maxed out levels. It seems like once our daily traffic reaches 10MB/s, a type of queue forms and the delays begin. Rackspace assures us that we're not limited to that.
Versions:
OS: cent OS on cloud
OS: Redhat on Dedicated Server
Apache: 2.2
PHP: 5.3 / MySQL: 5.1.69
Some more background info: The site is typically busiest from 7am until 3pm EST. For the past few days, we've noticed that between 7am and 9-10pm the server has just lagged incredibly. However, at around that 9-10pm mark, something changes and the pages go back to loading almost instantly. (There is still decent traffic though.) Then at around 7am again it slows to a crawl.
Rackspace has offered solutions such as spinning up another server and incorporating their load balancing - they are in the process of this BUT they do NOT think the traffic is the issue. At one point they actually said there was potential packet loss somewhere in the network, but no progress has been made.

Is there any web application to install a server and access KVM without the application HP desktop?
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.

View 13 Replies View RelatedI 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.
