Putty SSH Slow Open A Connection FROM ANOTHER SERVER

May 7, 2009

I am using Putty to connect to my server via ssh.

When opening a direct connection, i can login quickly without any problem

Server A Little Slow, Site Or My Connection?

Mar 1, 2008

I rented a server from VD a month ago and hosted some of my websites. But I'm constantly noticing that my websites are loading very slow. How can I check if other users are experiencing the same problem, or if the problem lies with my Internet connection?

SLOW Connection: 2 Webservers Using A Single Database Server

Jul 24, 2007

I am developing an application on a load balanced network.

It is configured as follows:

Webserver1, Webserver 2 (Fedora 5 - Linux, Apache, Zend Opt, PHP)

and a DataBase Server (MySQL)

When the webserver attempt to use the Database server the connections and page output are REALLY slow!

The database server is within the webservers local intranet - so I thought it would be a lot faster.

----------

Here is a quick test: : :

Testing Database Connection on localhost
Connecting to Database... 0.00054502487182617 seconds
SELECT * FROM users... 0.00076389312744141 seconds

Testing Database Connection on '192.168.1.200'
Connecting to Database... 19.998768091202 seconds
SELECT * FROM users... 0.0021719932556152 seconds

20 seconds to connect to the database server...

Slow Connection

Jul 21, 2007

I use Charter as my ISP. Normally my connection speeds are VERY fast to the majority of the web. However, my own website has become like molasses in January (it wasn't always this way, or I would have not chosen my host), as can the entire hosting service. For the sake of discussion, I use two networked PC's, one is Win2K and the other is XP. Both are using the latest free version of ZoneAlarm, NO virus checker. I have a Linksys router. Asking for tech support with Charter is equivalent to wanting to discuss the methods for rebooting your PC with someone who didn't grow up speaking English. I've tried, it's useless.

(Warning: my site is about nude art photography, so don't look if you don't want to see that. The site is pencilartist.com, and I am hosted with Lunar Pages.)

I've run tracert several times, and I always come up with a timeout on the first hop.

I've asked a friend to view both my site and Lunar Pages from his Charter account (lives 5 miles from me) and he says both come up in nanoseconds. I've tried various online speed checkers, and they all give blazing results.

Here's the latest tracert:

Slow Internet Connection To Our Website

Apr 20, 2008

For about the last two weeks I've had issues connecting with the website that I help run www.learnoutloud.com from my home connection which is Time Warner Cable Internet connection in Los Angeles. I'm on a Dell laptop Inspiron 6000 running Windows XP. I'm always able to connect to the site but what's happening is the page will get hung up on loading a single image usually and then it will take about a minute just to load that last image. And sometimes the page won't load at all, but all it takes usually is hitting the refresh button and the page loads instantly. I was hoping this issue would just go away, but it's been persistent after numerous restarts of our cable modem and switching from wireless to plugged in and so forth. And it's really only happening for our site and no others, which is just puzzling.

At our office on our DSL connection our site loads fine and we haven't had any customer complaints about the site loading slow like this. Our traffic numbers have stayed steady so I don't think it's a global problem connecting with our site. At home I conduct a trace route and it looks good:

Plesk 12.x / Linux :: FTP Connection Slow And Fails

Jul 1, 2014

OS CentOS 6.5 (Final)
Plesk version 12.0.18 Update #6, last updated at July 2, 2014 11:13 AM

The system is up-to-date; last checked at June 27, 2014 04:43 AM

All current websites on the server seem to work fine any new subscriptions we cannot get working at all.

We can connect via FTP to new sites SOMETIMES - just cant get directory listing. When we can connect and get into a directory it slows down.

In Active mode:
Command:MLSD
Response:425 Unable to build data connection: Connection refused
Error:Failed to retrieve directory listing​
Install Wordpress via the Parallels panel it loads and says it is all there, just can't log or display any pages. The default Parallels page is displayed.

Upload a html page via the File Manager in Parallels and it displays the default Parallels page.

Unpack the Wordpress tar file via File Manager and it displays the default Parallels page.

The Wordpress feature in Parallels says it is working fine, can't display any page, can't log in as it returns a 404 page or the default Parallels page.

Create a site in Presence builder and Parallels says there is a site. The default Parallels page is displayed when opening the site.

Go to DOMAINS and there is 0mb in space used and there are files listed in the File Manager - none of which can be displayed.

PuTTY Ssh -f Root@....

Nov 1, 2009

How do I configure PuTTY to produce the equivalent of this command:

ssh -f root@xxx.xxx.xxx.xx -L 3333:yyy.yyy.yyy.yy:80 -N

So far the configuration I've come up with is:

Source Port: 3333
Destination: yyy.yyy.yyy.yy:80
"Local"
"Auto"

This doesn't seem to do anything at all. I don't use windows much, so go easy on me

VPS Incredibly Slow, Huge Numbers Of Slow MySQL Queries For Plesk/Watchdog

Nov 11, 2008

I've got 25 domains on a Virtuozzo/Plesk8.6/CentOS5 VPS. Each domain has one up-to-date install of WordPress, most have very little traffic (average 200mb per month), maybe 2 domains get 5-7gb traffic per month.

I monitor port 80 connections and rarely see more than 10 at a time.
That should in my opinion be no problem at all for a VPS with 768mb guaranteed ram and 2.4ghz cpu. I've got 30gb hard drive spare too.

But.... about 8 or 10 times a day it grinds to a complete halt: server load at 500-1000%, sites timing out, plesk takes 3mins to load, often I can't even connect with SSH, and the plesk web server, apache

INSERT INTO module_watchdog_sys_stat (time, type, value, service_id) VALUES(FROM_UNIXTIME(1226404705), 'MAINMEM_USAGE', 17472, 11);

80 seconds sounds like a huge amount of time for a MySQL insert to me! Does anyone know if this is likely to be the cause of my trouble? Some problem with Plesk and the database? Or could it be something else?

Allow PHP To Open Sockets On Server

Nov 18, 2008

A potential client asked us the followingo you allow PHP to open sockets on your server? If yes, is there any restriction on the amount of data that can be downloaded?

Will we be able to access and load our remote webpage using PHP? We will use sockets and a Pear library to accomplish this.

We are basically planning on using some content from our remote site on the new site which will be hosted on your servers. Kindly reply back at the earliest.

Is this a potential spammer?

Alert: Open DNS Server

Apr 16, 2007

I've run "DNS report" test for one hosting in dnsstuff.com and got this warning (as some times before for other hosts:

---------------------
Fail:
Open DNS server

ERROR: One or more of your nameservers reports that it is an open DNS server. This usually means that anyone in the world can query it for domains it is not authoritative for (it is possible that the DNS server advertises that it does recursive lookups when it does not, but that shouldn't happen). This can cause an excessive load on your DNS server. Also, it is strongly discouraged to have a DNS server be both authoritative for your domain and be recursive (even if it is not open), due to the potential for cache poisoning (with no recursion, there is no cache, and it is impossible to poison it). Also, the bad guys could use your DNS server as part of an attack, by forging their IP address.

Is this anythhing important?
