FTP Crawls, But HTTP Speeds Are Fine.... For One Customer Only
Nov 21, 2008
Anybody seen something like this before? We have a customer who is complaining about slow FTP speeds. At first I thought his whole connection to our server is slow (he is in the mideast, we're in the USA), but through a series of tests and screenshots I've confirmed:
1) He can download from our server via HTTP at 500KB+/sec
2) If he downloads the same file, from the same server, via FTP, it goes <1KB/sec.
I've had him try different FTP software; same result. Maybe his ISP is rate limiting FTP?
Every other customer can download fine via HTTP and FTP, and all my tests from various testing servers I have around the world show good speeds from both.
I'm currently struggling with an issue on our Apache 2.2.24 home-rolled installation on an OEL 6.2 x64 linux server that front-ends for a Glassfish cluster via proxypass.The httpd.conf manages 4 virtual hosts with each virtual host entry rewriting to HTTPS.
Anyone trying to access the HTTP address redirects to HTTPS just fine.The issue is that anyone using the HTTPS address gets redirected to the Document Root defined in Apache instead of being proxypassed to Glassfish.
I had set up a dummy DocumentRoot with a simple index.html meta redirect and what happens is that anyone directly accessing HTTPS will hit the index.html file which redirects to the the https site. At this point it simply loops to infinity.
The memory usage on my server is fine, I watched the CPUs for a long time and watched the server load also, the CPUs were easily riding along not often going over 20% (I have 2) yet the thing is, the server load is very strangely going mad... It's rarely under 6.0 (2 cpus) and sometimes goes into 20s, yet the server doesn't slow, nothing stops working but it simply goes red and shows it's bad news.
I've been told that the only other thing that might be causing this is the hard drives... I have 2x160GB 7200rpm hard drives - not sure if they are SATA etc..
If anyone has any ideas as to why the server load is so high - but everything else is fine -
I noticed in the apache error logs that Yahoo and Google (mostly Yahoo) have been crawling one of my clients' sites for warez, cracks and serials, but these files don't exist (and hence they're ending up with 404 errors in the error logs).
The IPs that are doing this are legit (as far as I can tell)... 74.6.20.32, 74.6.74.50, 66.249.65.178
It's systematically hitting the server once every second or two, looking for files such as "free.serial.no.of.flash.professional.8.jsp", "trainer.SimCity.4.million.jsp", "Paragon.Partition.Manager.v.7.crack.jsp"
and this has been happening for at least a day now.
Now here's the thing. The site has gone through a redesign about 4 months ago, and the previous site was running an old version of PHP Nuke that was filled with spam (from tracebacks), and a photo gallery manager which was probably not installed securely. The new site utilizes Joomla, and all the previous elements are gone (in fact the site was migrated to my servers after the redesign, so my servers never hosted their old PHP Nuke or photo gallery).
These mysterious crawls from Yahoo and Google all seem to hit the photo gallery URLs, such as http://www.domain.com/albums/album01...v3.1.patch.jsp
The other weird part is, all the links end with .jsp. The site's previous server did not have JSP support, and neither does mine.
Also before we moved the site over to my server, I archived their entire website on their old server, and none of these files exist there.
Doing a search on Google on their site (site:www.domain.com) doesn't show any of these files. Searching Google for links that point to the site also don't show anything out of the ordinary.
This has me baffled... Does anyone have any idea what is going on?
I'm having the oddest issue. For some reason, some of the websites on my server load fine, and some take a really long time to load (2 minutes).
Now, the server load is fine, and the size of the sites aren't the issue either. I've restarted Apache and a couple more services, and still the same sites seem to load very slow.
What could be causing this since it's only effecting certain websites?
I have a problem with one of my domain. Some users around the world cannot access the website, but they can ping and traceroute the server without any problems. I am able to access the website perfectly.
Site URL is www.djluv.in
And we are using IPB 2.2
Moreover if theres another domain on the same server, they can access it.
There are about 25-30 users who are facing this problem, but from different part of the world so I cant even say ISP problem.
APF has been shutdown, no Ban Filters on IPB or cpanel.
What are the possible reasons why they couldn't access the website? how to fix the problem?
We are talking with a datacentre about colocation and im hiring a third party company to manage the servers 'on site' on our behalf.
Im looking for some feedback on the 'colocation agreement' and the 'server management agreement' to make sure were covering everything.
just to be clear, Ive got a server administrator who will access the server virtually so the only points of the agreement will be those tasks that need to be done 'on site'.
the points ive looked at so far are:
colocation agreement > 1u and 2u costs. > Server setup costs. > Power allocation and cost of additional amp's. > Bandwidth overages. > storage space for spares
onsite server management agreement > hardware replacement costs . > Hardware upgrade costs. > status monitoring. > general server management.
1) what else should be covered in the colocation details?
2) what should be included within the 'on site server management' agreement?
3) what should be included under the description 'general server management'.
for example: I think physical reboots should be part of the server management agreement, but how many on average per server per month should be included?
3) should hardware replacement cost be fixed rate per task or hourly, also do you have any suggestions regarding what to expect over a year (nothing exact, just a bit of guidance to help with the budgeting)
Combined these agreements should cover everything that we can not do remotely.
When I try to login to any accounts on my server via FTP the responce is:
Quote:
[20/03/2008 15:41:15] 331 User restore OK. Password required COMMAND:>[20/03/2008 15:41:15] PASS [20/03/2008 15:41:16] 530 Login authentication failed
I can login to their cPanel accounts fine using the exact same password so I'm not sure what the problem is. I've tried restarting the FTP server and syncing the ftp passwords using WHM -> cPanel -> Synchronize FTP Passwords but still no luck. I've tried changing the account password but I can still login to cPanel with the new password but not ftp.
I try connect to the ftp server via the IP address and domain (ftp.domain.com) but again, no luck.
i havent touched the config on my vps box for months and it has been running OpenVPN without any problems.
All of a sudden it is complaining it cant find /dev/net/tun
Nov 15 06:45:18 gizmo openvpn[23616]: Note: Cannot open TUN/TAP dev /dev/net/tun: No such device (errno=19) Nov 15 06:45:18 gizmo openvpn[23616]: Note: Attempting fallback to kernel 2.2 TUN/TAP interface Nov 15 06:45:18 gizmo openvpn[23616]: Cannot allocate TUN/TAP dev
any reason why it would stop working? i am on a VPS i have asked if the host machine parameters have been changed but in the meantime anything else i can check?
We have installed the latest version of Plesk on our server. Our web applications work fine. But we can not send or receive emails. Neither the webmail (login failed) nor pop3 / imap and mail forms on web projects.
All the videos have been uploaded to << link removed >> and in there you will seea flash_video directory, in there should be a html file where you can double click and watch the flash video.
Now go ahead and try it, click on the HTML file and click CONTINUE and try clicking on MODULE 1.. You will see a video play to the left but on the right are bunch of POWERPOINT slides that will appear as the guy continues to speak. THAT DOESNT SHOW..
Our website is hosted by xo.com
Dont know much about the plan since its my 2nd day at the job..
But here is the weird part,
i have uploaded the samething - same exact way to another web host and it plays fine, the PPTs show up fine..
What do you guys think it is?
Before someone asks about uploading methods, i tried filezilla, coreftp and cuteFTP using both ASCII and binary methods. Samething..
Im currently running a streaming media (video) site on a p4 3.0 GHz with 2 gigs of ram. I think its a 10mpbs unmetered port. It streams extremly slow, to the point where it lags every second. It does this even though their is only 6 people on, with loads of 200 it just freezes up. What configuration would be able to hold traffic of 200 people constantly. I was on a faster server with hostgator, their dedicated pro but i went through the bandwidth in 5 days.
Just wondering really, if you have a 1U cooler like an Akasa AK-CC029-5 or Dynatron P199, do these generally run full speed 24x7 or should they be bios controlled?
I've never had any cooling issues or reliability issues with either of these coolers, but they don't seem to want to be controlled through the bios on all of the boards I have used, so they run full whack 24x7
For those of you that complain about the slow loading speed of your sites due to being on over-loaded servers or over-sold bandwidth, why do you think that the discounted rate is worth the loss of customers that you might earn if your site loaded faster.
Have you ever given your sites a try on a quality host where your site loaded faster? You might be surprised at how much more effective your marketing was when surfers stay around long enough to see your site load.
Some times in the effort to secure such a great deal and save a penny, you wind up loosing a dollar, it might not make a difference to all of you but some will be surprised at the ROI for a bit better hosting!
how to tune linux (currently running fedora4) server to improve download speeds for the client. I have observed that if i download from sun it is very fast compared my own server which is hosted on cogent backbone or any other.
Please take into account that both mine and other server both are at relatively same number of hops and ping time. and my server and the carrier has enough bandwidth to fill whole 100mbps, even the client is a server which is on a different backbone which can fill whole 100mbps, also guys i was able to fill whole 100mbps while downloading from sun. but when i download test file from my server it is lagging at 3mbps around. only single thread using wget command. Now what is it i need to do to get my server able to push full pipe even for single thread, ping time is 25ms. if not full at least half. let me know if you have some workaround, and server is apache no load.
i am changing my hosts from hostgator to the JustHost or ImHosted.
I am trying to buy shared hosting plan. I DO NOT want a video sharing website. My website will serve around 100-150 videos of each 5 mints duration.
I am confused about speed of these hosts.
My questions are
1. How can i check the speed of these hosts (JustHost) & (ImHosted). (Any sample file download will do)
2. How can i know which of these host has the fastest data transfer rate to my country. (PAKISTAN)
3. ImHosted says it has OC-192, JustHost says it has OC-96. But how to confirm it?
I am inclined towards JustHost as they are way cheaper than ImHosted. But i am also concerned about speed. Will a OC-96 connection(JustHost) will serve a 5mint video well.?
I'm currently using ipower, which just switched to fewer but larger servers. The impact for me is a new throttle in download speed, which is about 350KB/sec (although I can do FTP downloads when logged in at 500KB/sec. Previously, with the more but smaller servers, you just got a share of what was available on the server with no throttle, and when activity was low on a server, it was enough to max out my cable's limitation of about 1.5MB/sec (12 mega-bits / second).
It seems that few web hosting sites will specify typical download speeds from a web hosting account. I'm hoping that members here could report what they are getting from various web hosting services.
My web site is
jeffareid.net
A "hobby" web site, mostly videos from car racing games, just niche market enough to not attract excessive traffic.
I just found that my VPS uses ADSL - which makes no sense since the download speed into vps isn't important, it is the upload speed. BTW, it has 100mbps port - so the port is fine, it is the network.
1. What upload speeds are available for VPS's (in mid price range)?
I serve mp3 dj mixes for some friends and am coming up on the end of my current hosting contract here in the next couple of months. They have been a fantastic host the only reason I am working on looking elsewhere is cost-related.
I got a unbelievable deal when I signed up last year and it would run me almost $300 to renew for another year, which is out of my price range.
Aside from great uptime (99.97% over 10 months), the thing I really like about the current host is their download speed. I have a 1mb cable connection at home and consistently download files at 850ish/kbps. Everyone I have spoken with has experienced similar speeds. This is much faster than any host I have ever used and is twice as fast as another host I use.
So, what I am looking for is a host that offers something similar in that regard that's around $10/month and optimally has coupons/deals floating around.
I would be happy getting 650kbps/sec, obviously the faster the better. Uptime is always a consideration, however this is more of a hobby and I am not expecting the same uptime that I get currently.
I am not against using a dreaded 'overseller' for this venture, I just need something that pushes large files fast.
I have plenty of time to find a new host, but would like to start getting a short list put together so I can request test files and whatnot.
I've recently purchased a VPS 250P package from EuroVPS and actually signed up for a two year contract as I respect the company so much however the speeds I've got, since finishing optimising the server, surprise me.
I'm already using a VPS from another dutch company until I move everything over to EuroVPS but the difference in speeds are a little concerning to me.
Please can you guys look at these response times and tell me if they are normal?
Current VPS: Page created in 0.035 seconds with 11 queries.
EuroVPS: Page created in 0.199 seconds with 8 queries.
Both servers are using the same spec, optimisations and PHP cache however my current VPS is using Apache1/PHP5/MySQL5 and with EuroVPS I can't afford to get them to upgrade to version5 so it's running on Apache2/PHP4/MySQL4.
I did get this response from EuroVPS, does it explain the difference in times?
"...we are using enterprise kernels which are slower than standard SMP/UP kernels. The performance of our VPS instances is not as high as some competitors who are using these faster, but smaller kernels.".
Once again, I have the utmost respect for EuroVPS and love their support but would appreciate some opinions on this from you guys.
I have seen that most hosting companies will post a download link with a file for speed testing purposes. I understand that I can download this and watch the speed, etc. What is the best way to do a download test?
For instance if I just download the file to my machine I am concerned that I am not doing a good test. I am using firefox on XP and while the download is running it shows a speed that goes up and down. I am not sure if that is a realtime number or a cumulative number based on the total download to date. If it is cumulative then I guess I would just watch the number towards the end of the download to get an idea of the speed.
I have been lurker for long time already but now decided to ask this question I have been wondering about past few months.
I rent an dedicated server from KeyWeb, with dedicated 100mbps link. The server itself isn't that good & fast, but it's just perfect for my gaming server (E4500, 2GB DDR-2 ram and 2 x 320GB sata 2 drives)
Now to the problem. Always when I download some big files with this server from ftp or html server, and if I only open one connection, speed is very poor... Like 1MB/s or so, but if I use some download manager or torrent client which opens more than just one connection, +10 or so... Then the speed is very good, sometimes it goes up to 15MB/s. The server is actually connected to 1gbps switch but I think the port is limited to 100mbps.
At speedtest (dot) net, I get results like 17mbps down and 8mbps down.
So... Is that normal or is there something wrong? I've not contacted them yet, but if this isn't normal. I will Ofcourse I'll try to solve this on my own.
and before someone asks if this ftp I'm downloading from is not fast enough... I can tell you, it's. I downloaded one big file from it at school and at max speed was about 9MB/s
I have several servers here at my home. I want to run them up on a really fast upload like 10 - 100 mbps. How would i get this in the UK at home. I heared that you can get multiple connections and blwnd them together. Is this right.
I am trying to gather more information regarding Mediatemple's Nitro DPV service and also MT's network speed/connection.
Most information I see is regarding the Gridserver service which is quite poorly reviewed, but I would be quite skeptical if this census could also be applied to the higher end Nitro service? -- the Mediatemple service is running sites like Techcrunch, Mashable, etc. so I am assuming the service is better with the higher end Nitro service?
There hasn't been any reviews of the Nitro service, so still trying to get some feedback from current Nitro customers or MT Complex Hosting customers. Any here who would like to share?
As far a network speeds, the ping does seem slightly slower than some other host (according to pingdom tools), but suppossedly they are a tier 4 data center if that means anything.
