Complex Initrd Issue Probably Involving A Broken Sh

Aug 10, 2007

We had someone take a look at our server for security issues, and they believed that one way of keeping "hackers at bay" would be to write an sh wrapper that only allowed root access. Well, this immediately broke the system.

I have spent about six hours now attempting to fix this. We're using Red Hat Enterprise 4, and the recovery disc doesn't have the SCSI drivers we need to even mount the hard drive, so that's out. I can't skip initrd because it apparently contains the drivers for the hard drive, but it's also not allowing the system to boot up. I have tried setting kernel emergency in grub, but it still loads initrd and breaks. Without initrd, I get a kernel panic while mounting the hard drive. Annoyingly enough, doing cat initrd-version.img at the grub prompt shows the file just fine, so why is initrd required for mounting the drive if it's already accessible? Also, it doesn't look like there's any way to edit initrd from grub, which is a real pain in the head because I could always comment out the offending lines. And of course, even though I can see the initrd file, I can't do anything else with the file system. I have requested of the data center to provide a boot disc that can mount the hard drive, and if that can be done, then I can go in and make the changes immediately and hope that it works, but without that, it seems I'm stuck. Any suggestions?

When I say "broken", what happens is I get "Out of memory: Killed process x (procname)" which then repeats itself infinitely, killing any process which would load.

The data center says that they HAVE no boot discs capable of mounting the hard drive. This is utterly ridiculous, because the only option from here is to order the expensive OS reload. I'll never use Red Hat again.

SEO Involving Hosting

Sep 18, 2008

If I am putting up two sites that are going to receive high amounts of traffic and have many links to each other, is it better to host them on separate servers? Right now the first site is changing over to a dedicated server and I'm wondering for SEO purposes if it's better to put the second site on that server as well or place it on a different server? I know that links coming from the same server or c-block don't carry much weight, so which route should I take? (the first site is already receiving over 6,000 uniques a day.

High-End Complex Hosting Solutions

Jun 29, 2009

Other than Rackspace, can the good folks here recommend some data-centers that have experience in handling the following solutions:

SAN (F/C, 10Gbps), 9TB usable capacity, complete redundancy, and real-time mirroring to an additional SAN in a separate geographic location.

redundant Brocade SAN switches

Servers: Quad processors, quad core, 48GB RAM, 8x146GB SAS Drives, multiple 1Gbps NICs

VMWare installations and handling.

Load balancers (preferably Brocade)

Dedicated L3 switches

I'm not just looking at providing this, but someone who can truly manage it 24/7 - management from VMWare and SAN perspective.

I saw some niche datacenters, but ran into the following problems:

(a) singular location.

(b) support for VMWare and SAN provided during business hours only

(c) no prior experience in real-time SAN replication / VMWare, Oracle/MS-SQL Replication.

Fantastico Broken

May 26, 2007

I don't know how it got broken, it was working a couple days ago. When users click the fantastico icon in their cpanels, a page opens that says this:

Fantastico is not installed at the default location /usr/local/cpanel/3rdparty/fantastico. Either move the Fantastico directory from it's current location to /usr/local/cpanel/3rdparty/fantastico OR enable ioncube loaders in WHM -> Tweak settings.

I enabled the ioncube loaders and that didn't fix it. So then I reinstalled fantastico and it's still broken.

How do I troubleshoot?

Broken BIND

Jul 24, 2008

I ran "yum update" on one of my servers, and it must've updated BIND, because now named doesn't start.

I basically hit all the problems in this thread:
[url]

This is CentOS4 with Plesk.

Even though I don't have that package installed, and tried every suggestion there, it still doesn't start... I mucked with the configs and moved so many files I don't know how to get back to where I started.

Quote:

Jul 24 05:08:06 www named: /etc/named.conf:67: open: /etc/rndc.key: file not found

What's my best bet for fixing this mess? I sent in an e-mail to two "server administration" companies I found in signatures here, hopefully one of them will be available today.

I changed the nameservers on critical domains to a free DNS service to get them back online, but they're acting oddly (like DB timeouts), perhaps because of the lack of a local nameserver to talk to.

But in the meantime is there anything I can do to try to fix this quick?

CPAN Is Broken...or Something

Jun 15, 2007

I'm trying to install some basic cpan modules to use ASSP with. On my other server, this all went without a hitch, but on this one (Centos), it it a pain. First off, every time I start up cpan, it's asking me to do some sort of reconfiguration..every time (running as root)...

Secondly, after I'm in the cpan shell, and I issue this:

Plesk 11.x / Linux :: SSL On Email Broken Since 11.0.9

Jul 23, 2014

Code:
# cat /root/.autoinstaller/microupdates.xml
<?xml version="1.0" encoding="UTF-8" standalone="yes" ?>
<patches>
<product id="plesk" version="11.0.9" installed-at="20121209T212320">
<patch version="62" timestamp="" installed-at="20140723T035123" />
</product>
</patches>

Minutes after this microupdate auto-installed, I am unable to login to POP and IMAP on this server. None of the accounts are able to login. The logs indicate hundreds of login failures, accompanying a new record I've never seen in these logs:

Code:
pop3d-ssl: Unexpected SSL connection shutdown.

Unfortunately, I can't find anything about what MU#62 actually included. The changelog only indicates up to MU#61, so I'm very concerned:URL....

I've googled the specific error I'm seeing above, but nothing appears to be remotely related to this problem.Is it possible to roll back the MU to determine if that is in fact the problem?

Hard Disk Went Broken And I Need To Recovery Data

Dec 26, 2007

My server (Fedora Core V and Plesk 8) hard disk broke 2 days ago and my bakckup tar.gz is too old.

Datacenter (fdcservers.net) tried to put old harddisk as slave but server is not recognising the old drive. Datacenter say that can not do anything more.

My question:

Is there any software or company that can recovery my harddisk data?

Plesk 12.x / Linux :: Panel Broken After Upgrade

May 18, 2015

Following the update from 11 to Plesk 12 (and installing latest Ubuntu fixes), the Plesk panel access is broken. Welcome page says:Can not load key: key is empty.And of course, no way to login the mgt interface. All services appear up, so this is only affecting the panel web service.

Fishing out the panel.log, it appears to be at a lower level than I initially thought (see below): experiencing issues after updating from 11 to 12 on Ubuntu (12)?

Plesk 12.x / Linux :: After Upgrade FTP Explicit TLS Is Broken

Jul 8, 2014

Unfortunately the encrypted FTP transfer is broken since Plesk upgraded to version 12. There are two cases:

Passiv FTP without encryption on port 21: everthing workes fine.
Passiv FTP with explicite TLS encryption on port 21: The control connection can be established by using TLS on port 21 but the data transfer can't be established by using passive mode (ETIMEDOUT - Connection attempt timed out)

I thought it could be a firewall issue but i'm currently unable to diable the firwall for testing since the configuration of the firewall is unreachable after upgrading to plesk 12! See second thread:URL....

HD Died, OS Reload Partially Broken, Dead In The Water

May 29, 2008

I've a dedicated server at ThePlanet / Servermatrix for the past few years and for the most part the service has been okay. Uptime has been good and support used to be fairly swift.

Early wednesday morning the primary hard drive in my server started dying. Throughout the day various services kept going up and down and overall the entire server was very unstable. I didn't get much movement from ThePlanet's support team - they would reboot the server, SSH and other services would come back online, and so they would close the ticket.

Thirty minutes after the reboot the HD would switch to read-only and stuff would start dying. So they finally recommended that I replace the HD and do an OS reload. I said fine as I had a backup of all of the accounts on a 2nd hard drive.

Well it took until 6am this morning for the OS reload to finally be completed, but when it was done apache was *completely* screwed up. WHM was up and running but if you went to the server IP address in the browser you got an error.

It turns out that something really badly went wrong with the OS reload but it took them hours before they even admitted that there was something wrong that needed more action. It's now 10pm and while email and other services are up, apache is still nonexistent.

When I try to run easyapache it barely starts before it errors out with a bunch of missing dependencies. I cannot instal GD and a bunch of other items, and I keep getting error messages that SSL isn't installed either.

Please visit [url] for help with this error.!
No original working apache backup to restore!

I can't even transfer my accounts off the server as that's also broken - I was going to all of the accounts off to my KnownHost VPS but I keep getting an authentication error ("sshcmdpermissiondeny") even though I'm definitely entering the correct root password.

Plesk 11.x / Linux :: SSL Intermediate Certificate (Broken Chain)

I bought yesterday a SSL certificate from Comodo (PositiveSsl).

Plesk 11.x / Linux :: Broken Certificate Chain With Roundcube

Jan 21, 2014

My current configuration is: Ubtuntu Server 10.04, Plesk 11.5 and Roundcube 0.9.5 (installed via Plesk as the default webmail application) on Apache.

I played around with an SSL checker (https://www.ssllabs.com/ssltest/) to test my certificates and I found out that Roundcube delivered a broken certificate chain. It didn't deliver the intermediate certificate correctly. I searched through the configuration file of roundcube (/etc/apache2/plesk.conf.d/roundcube.conf) and discovered that there was only an entry for SSLCertificateFile.

To fix this I added the intermediate certificate via SSLCACertificateFile to the configuration file:

Code:
SSLCertificateFile "/opt/psa/var/certificates/cert-1sCtWB"
SSLCACertificateFile "/opt/psa/var/certificates/cert-FGLFqQ"

The only problem is that this configuration file is generated automatically:

Code:
#ATTENTION!
#
#DO NOT MODIFY THIS FILE BECAUSE IT WAS GENERATED AUTOMATICALLY,
#SO ALL YOUR CHANGES WILL BE LOST THE NEXT TIME THE FILE IS GENERATED.
