vulgarbulgar's questions

i've placed a pcie raid adapter card with onboard ssd's (AORUS RAID ADAPTOR built in with 4 x PCIe 3.0 512GB NVMe SSD) in a new (2020) Dell (Optiplex 7080).

the system boots fine most times, but it tends not to find the drive during a soft reboot, for example. it's very temperamental on boot, but works fine once the OS is booted.

the built in boot diagnostics produce the following warning:

PCIe - Training error on device - Link degraded, macLinkWidth = x16, negotiatedLinkWidth = x8

is this warning related to the boot device being not found sometimes or simply indicating the card is x8 and not x16?

if unrelated, what could be causing the system to not find the boot device at times? i've checked and reseated the drives on the adapter, and the adapter within the pcie card several times.

thanks for looking.

This is a canonical question about setting up SPF records.

I have an office with many computers that share a single external ip (I'm unsure if the address is static or dynamic). Each computer connects to our mail server via IMAP using outlook. Email is sent and received by those computers, and some users send and receive email on their mobile phones as well.

I am using http://wizard.easyspf.com/ to generate an SPF record and I'm unsure about some of the fields in the wizard, specifically:

1. Enter any other domains who may send or relay mail for this domain
2. Enter any IP addresses in CIDR format for netblocks that originate or relay mail for this domain
3. Enter any other hosts which can send or relay mail for this domain
4. How stringent should SPF-aware MTA's treat this?

the first few questions i'm fairly certain about... hope i have given enough info.

we have a dv server with mediatmeple, running apache 2.2, and plesk panel 10.3.

for some reason, when sending mail from our domain to theirs, or when they send email to ours, the messages bounce back with the 'retry timeout' error.

before messages bounce back which we send out to this domain, i see them stuck in the mail queue in plesk panel: http://i.imgur.com/lRrqy.png

example of info in bounced message:

a quick dns report - anything vital on there in need of attention? http://www.dnssniffer.com/en/report/advanced/floridaseating.com

SOLVED- response from Media Temple support:

Checking the domain names for an MX lookup, the IP address that was returned was on our blacklist due to malicious activity. As there has not been any recent malicious activity from this IP address, we were able to remove the ban. You should be able to receive email from sitconf.com / suite22.ca now. Please verify.

issue: misoncifgured dns?

symptom: when i visit http://www.borisnikolaev.com/index.php?option=com_content&view=article&id=51&Itemid=53, it shows what should be on http://www.floridaseating.com/index.php?option=com_content&view=article&id=51&Itemid=53

if i remove the 'www' subdomain, it works as usual.

this occurs for several of the other domains on this server, and when using any subdomain, except those in the dns zone file (excluding www).

the reason i noticed this is because google had indexed several of the pages under the wrong domain name.

primary domain dns configuration: http://i.imgur.com/ITx4F.png

secondary domain dns configuration: http://i.imgur.com/vknWN.png

any help is appreciated!

i have a dv server with mediatmeple, which has apache 2.2, and plesk 10.4. i have switched off the dns management in plesk, as i don't resell hosting, and manage that through mediatemple's account center page.

FOUND SOLUTION, thanks to direction by @cjc

Following should work. Add to vhost.conf file typically found in /var/www/vhosts/domain.com/conf

ServerAlias *.domain.com
RewriteEngine on
RewriteCond %{HTTP_HOST} !^www.* [NC]
RewriteCond %{HTTP_HOST} ^([^\.]+)\.domain\.com
RewriteCond /var/www/vhosts/domain.com/httpdocs/%1 -d
RewriteRule ^(.*) /%1/$1 [L]

i just got a DV server with mediatemple. Here is the basic setup:

• CentOS 5.5 x86_64 (64-bit)
• Apache 2.2.3
• MySQL 5.1.54
• PHP 5.3.5
• Perl 5.8.8
• Ruby 1.8.5
• Plesk Panel 10.4
• YUM package management

i've added mod_pagespeed, and suPHP, but that's about it.

on to the issue.

one of two test sites only loads in chrome (and default android browser), though not in IE or FF (internal server error). the other loads fine in all browsers i tested with. both are in pass-protected directories. visiting either in all browsers leads to password dialogue, but once info is entered, one gives the internal server error in IE and FF.

here's what i see in the httpd error log: (the same prints every time i restart httpd over ssh)

not sure if this is enough info, but is all i could come up with for the time being.

UPDATE: i just also noticed that, when accessing through IE or FF, my antivirus pops up, stating it has detected a 'DNS poisoning attack' - not sure if legitimate, or just a false positive.

UPDATE 2:

ok, the error that popped up for the domain in question:

[error] [client xx.xx.xx.xx] Script timed out before returning headers: index.php.

when i looked it up, it was related to the TimeOut setting in the httpd.conf, which was set at 20. i increased it to 300 (5min), and the site now loads in all 3 browsers. however, it takes about 1-2 minutes to load essentially plain-text pages in FF and IE, while chrome seems normal.
