Server Settings For Blogs
Jun 7, 2008
I use a couple of different hosting companies.
Recently, I've begun setting up blogs.
I've been trying to set up blogs on Company "A" for the past month and have had nothing but problems.
While waiting to hear back - one more time - from tech support on Company "A"
I set up a blog on Company "B". Everything set up perfectly, smoothly and in about 1 hour I had the blog up and running.
I'm using 2.5.1 WPB and plugins that are NOT known to have "issues".
I've used the same themes and plugins on "A" and "B".
I changed permissions on a couple of the plugins (company A) and the plugins just disappeared.
I tried setting up widgets and none work.
if there are specific settings server side that make setting up blogs work/not work?

Let's say a dedicated server has following specs:
Single quad core 2Ghz Xeon cpu
4Gb ram
250Gb SATA
100Mbps connection
and each blog has latest WP version and some plugins(without supercache) installed, 100 unique hits/day.
so how many blogs can I plant in this box?
(bandwidth is not considered.)

If i like to put 30 wordpress blogs on a vps no high traffic blogs will be between 50-250 uniques per day per blog and with space to grow if some blogs start attract good traffic
Im thinking about spending $59usd
but most important would be to find a suitable vps for what i need , what specs would
you recommend for this kind of usage?

Does anyone know of a tool (I've seen it before but forgot the name) which is a bar like 100x30 in pixel and when you click it, a box popups allowing you to select facebook, orkut, myspace, wordpress, etc etc, and you can blog the current site url you are surfing?

I have been building a business around blogs and other social media items on mostly OSS technology - but unfortunately, my current reseller account is inadequate for what I need (especially with sites that query a DB) and unable unfortunately to upgrade to what I might need. I don't want to rip on them because they've provided me great service, but they're just not able to ramp up. My thought is there won't be any reseller to meet my needs after learning more info, so I'm going to make the leap up.
I'm not going to go pound the pavement for hosting business; this is only really for my clients I serve as a agency/consultant/designer and my clients need and deserve more.
I have been considering Mosso; but also weighing a dedicated box as it's around the same price and looking around here for the solutions people recommend for the past few hours. But since I sort of have a specialty application, I thought I'd ask for your recommendations.
I want to say that I came here from another forum because my provider was affected by the Planet outage and the conversation and knowledge was great; you are a very smart community. I hadn't heard of this place beforehand but am glad I found it.

I am using aplus.net to host a WordPress blog and want to create more blogs.
Since aplus.net took 26 hours to restore my blog when somehow it was corrupted (no explanation on what they did), I have decided I need to host it someplace where I have full control.
I would be prepared to reinstall WordPress on my own. I also want to have the ability to control redirects. aplus provides a handful of very weak tools for managing the site.
I'm looking for a host that would allow me to manage multiple domains, and multiple instances of WordPress. I'm prepared to manage the MySQL db (if I have to, though I would prefer it if I had support for this).

I have a problem with my csf setting dunno why now when i start csf i block my server, i come from backup before with same config and working very well dunno why not working in this time.

# following setting:
GENERIC = "1"
# Testing flag - enables a CRON job that clears iptables incase of

# are sure that the firewall works - i.e. incase you get locked out of your
# server! Then do remember to set it to 0 and restart csf when you're sure
# everything is OK. Stopping csf will remove the line from /etc/crontab
TESTING = "0"
# The interval for the crontab in minutes. Since this uses the system clock the
# CRON job will run at the interval past the hour and not from when you issue
# the start command. Therefore an interval of 5 minutes means the firewall
# will be cleared in 0-5 minutes from the firewall start
TESTING_INTERVAL = "5"

# Port Scan Tracking. This feature tracks port blocks logged by iptables to

# PS_LIMIT within PS_INTERVAL seconds, the IP address will be blocked.
#
# This feature could, for example, be useful for blocking hackers attempting

# and have removed 22 from the TCP_IN list so that connection attempts to the
# old port are being logged

# Note: This feature will only track iptables blocks from the log file set in
# IPTABLES_LOG below and if you have DROP_LOGGING enabled. However, it will
# cause redundant blocking with DROP_IP_LOGGING enabled
#
# Warning: It's possible that an elaborate DDOS (i.e. from multiple IP's)
# could very quickly fill the iptables rule chains and cause a DOS in itself.
# The DENY_IP_LIMIT should help to mitigate such problems with permanent blocks
# and the DENY_TEMP_IP_LIMIT with temporary blocks

I have purchased a proxy website using phproxy script hosted at dedicated server. Its now about 4 months and everything is fine but i want to move my site to another dedicated server provider because current one has some issues.
When i purchased that site seller told me that he has optimized server and installed some scripts {server scripts} to get best out of proxy website. Now seller is out of my contact.
I am very much pleased with current server settings but i need to move. So i want to make sure that i can optimize new server and install same scripts to keep going with current performance.
I only know about http.conf settings and i have noted it ... plz help me about copying every other settings which that guy had done to optimize the server and how can i know which and where those scripts are installed which has made server quite efficient?

I just got a new server, and for some reason it is as though it always sends out codes to your browser to completely reload (like hard refresh) all images... Even if you hit "Refresh" in firefox, it wants to reload ALL Images. I uploaded the same EXACT files/webpage that it is doing this to on another server and it treats it normally, Firefox caches it. But on my server it wants to reload the images each and every time.
Tried on multiple computers, same thing.
Anyone know where this 'setting' might be? I do have full access to the server, though I was not the one to set it all up initially.

Just have some questions regarding server settings and security
1) What will happen if
Open_basedir in php.ini is changed to
Open_basedir = /home:/tmp
?
2) What will happen if all hosted users in passwd file are set to /sbin/nologin ???
Dose it effect running the web site?
What are the effects if
Sync if set to /sbin/nologin default is /bin/sync
shutdown if set to /sbin/nologin default is /sbin/shutdown
halt if set to /sbin/nologin default is /sbin/halt
news if set to /sbin/nologin default is empty
netdump if set to /sbin/nologin default is /bin/bash
Mysql if set to /sbin/nologin default is /bin/bash
mailman if set to /sbin/nologin default is /bin/bash
cpanel if set to /sbin/nologin default is /bin/bash
3) How to make /bin/bash in passwd file is the default path for each new user added (automatically) in cpanel/whm server
4) What is the effect if base64_encode and base64_decode if been added in disable functions?
5) How to secure host.conf and nsswitch.conf to prevent DNS lookup poisoning and also provide protection against spoofs?
6) How to secure the system configuration file sysctl.conf to prevent the TCP/IP stack from syn-flood attacks?
7) What is ClamAV and how to disable it?

Since 12.0.18, when I go to Tools & Settings > Mail Server, I get this error message on the page:
"Error: The limits on outgoing mail will not work for the subscriptions that have IP addresses from the white list. To make the limits work, remove IP addresses from the mail server's white list".
However, the whitelist page just contains 127.0.0.0/8 and ::1/128, and all my subscriptions have an external IP address which is clearly not in the whitelist.

I have just moved away from Kloxo Hosting, and I am a bit confused as to how I go about setting Client domains to use the (Already Registered) Nameserver Records I have created on the server.
You see, when I create a customer, the template adds the domain with it's own nameservers, ex: (ns.customerdomain.com -> 0.0.0.0) I don't want this to be the case.
What I would like to achieve, is for all my client's to have their NS records pointing at the NS records I already have registered on the server.
The reason for this is, when I submit the registration document to my local registrar, I have to specify the nameserver address for the domain, however, I only have 2 IP's on the server. I cannot glue every customer's domain FQDN to an IP.

After a server migration, some critical Plesk settings were not copied across, even though the option to backup/restore panel configuration was used. e.g.
skeleton (vhosts.skel folder)
php.ini (Program Files (x86)ParallelsPleskAdditionalPleskPHP5* folder)
Default site (vhostsdefault folder)
health config (Program Files (x86)ParallelsPleskadminconfcustom-health-config.xml)
Additional Administrator accounts
Is there a way to get these things to backup and restore that I am doing wrong?
Are there other important settings/data that I have missed from that list? I am still paying to keep the old server in case I discover something else!
Using Plesk Backup & Restore for disaster recovery will lose these settings unless they take extra steps. e.g. I now have a simple batch file that copies these files to a private folder on one of the domains before the daily backup kicks in.

We are trying to use a configure settings for an external SMTP server within Plesk (Windows 2008 R2 Plesk 12) but are receiving the following error message:
Error: Unable to encode IDN email address 'username': email address is invalid
We are trying to use a username for SMTP authentication as we do not have the option of using an email address with our current SMTP relay provider.
Is there any way around this so that we can use a username rather than an email address?

how to set up dns correctly as I have been trying for over a day now and not succeeded!
The situation is that I am using whm/cpanel. I have a domain hosted with godaddy that I want to point at my vps space. I have entered the nameservers into godaddy, and it now shows the placeholder page when I go to my domain.
I have set-up a user with ftp access to my main domain in whm, and uploaded an index page to test.
If I type in my domain name it goes to the godaddy placeholder page, if I type in the IP address it goes to an apache 'great success' page, and if I go to the same IP but with the users name added, it goes to the index file I uploaded.
I have played around with dns zones and A records but cannot get the index page to show when I enter my main domain name.

Our business is in the middle of changing to a Exchange based Email Platform which will be take effect in a few months, NOT NOW but planning ahead I'm trying to help with the DNS issues behind the scene. The current Host and Registerar is flarehosting. However I have just transferred the Domain Name to my NAMECHEAP account and need to take over the DNS Controls. I want to make SURE this is done without ANY downtime for the company (website, current email system). After contacting the current host for correct settings I have 3 things I need help with.
newerafinance.com 208.21.164.25 (Used for Domain)
mail.newerafinance.com 208.21.167.4 (Used for WebBased Email AND pop/smtp)
MX is mail2.uploadmysite.com
I was told with the above info I need to setup ARecords, CNAME, and URL Redirect and MX records. Before I try this myself I’d like some help with how this should be setup.
Exchange server will up at a future date so we need the current Email system to remain the same. Half of our users use pop/smtp and other half web based email.

I have IIS on my computer and I want to start using a php driven forum (SMF) on my web site. Before I upload the files I need to check the following settings are on:
the engine directive must be On.
the magic_quotes_sybase directive must be set to Off.
the session.save_path directive must be set to a valid directory, or empty.
the file_uploads directive must be On.
the upload_tmp_dir must be set to a valid directory, or empty.
I cant find anywhere within IIS where these directions maybe found. Can anyone point me in the right direction?

I am being rejected by Hotmail when sending mail from my VPS. I want to send mails from punbb and OSCommerce, with various website hosted on one VPS/Cpanel/LAMP solution. And with sendmail or SMTP, it'a always the same : passing almost every ISP except Hotmail/Gmail. I also always get this part in my email header regardless of which website i'm sending email from :
Code:
Received: from host.locker4adream.com ([74.200.75.7])
by host.locker4adream.com with esmtpa (Exim 4.68)
So I think it's the host.locker4adream.com part that makes me rejected. Because it's almost the only line in the email header that is different when I am using Outlook/Thunderbird to send mail. This ip (74.200.75.7]) is mine and I never spammed or anything.
So i asked my host ro add rDNS. And I added this line to my DNS zone on my mail domain:
Code:
lockeradream TXT "v=spf1 mx a ptr ip4:74.200.75.7/32 ip4:74.200.81.156/32?all"
I am really out of solutions! Can anyone tell me if the SPF record stated above is ok?
