What Does "Server Refused To Allocate Pty"
Jun 19, 2009
On one of our servers, a Athlon 64, 4 GB DDR2 RAM, Linux server with CentOS 5.3 64-bit installed and running the latest kernel (and which is located entirely different from the previous post, in a different city and DC), after installing some packages using yum and installing the latest PHP and Apache from tarballs, the server began slowing down and hanging on trying to do additional yum installs.
So, we rebooted and logged back into our SSH shell and got "Server refused to allocate pty" after entering the password and then, nothing. We can't run other diagnostics or anything to determine the issue, look at any logs, etc.
What does this mean and does anyone know how to fix it without reinstalling the OS? We have rescue mode available to us but we're not sure how to use it to fix this problem.
We look forward to your solutions-oriented responses.

Basically I installed wordpress in the same mysql as forum... but wordpress uses different username to connect to it. I wonder if there is any security risk associated with this, like would it be better to move out wordpress on to a different db? what about speed? what if my forum receives allot of mysql usage?

I am having some server issues.
A part of my sshd_config:
Port 2255
Protocol 2
ListenAddress 8x.xx.xx.46
PermitRootLogin no
Recently, when I want to connect to my server using putty, I get "Connection Refused" using the above IP address and port.
When I enter the above IP address (or any other IP address that is stored/set on the server) and port 22, I get "Server refused to start shell/command".
It did work before, using 8x.xx.xx.46:2255 and when I enter 8x.xx.xx.46:22 it will block. But now... not anymore.
I am using "Direct Admin" to do a "System Backup". I do see the right port and IP address in the sshd_config file.
How can I fix this? I can not login the server anymore, however I am going to the datacenter tomorrow.
OS: CentOS
Installed firewall / protection: APF + BFD
Control Panel: Direct Admin

I just configured the plesk server to only allow ftps connections.
When I try to access with a ftp account on the server itself it works well, however when I try to access it from a client PC it get these errors :
(...)
Response: 200 Type set to I.
Command: PASV
Response: 227 Entering Passive Mode (XXX,XXX,XX,XX,XXX,XX).
Command: LIST
Response: 150 Opening BINARY mode data connection.
Error: The data connection could not be established: ECONNREFUSED - Connection refused by server
On the client PC I configured Filezilla in Passive mode with "Require explicit FTP over TLS".
Normally for the firewall only the port 21 is needed or am I wrong (with explicit FTP and passif configured)?

I have a VPS acct with Plesk, am peaking out my system ram at 128mb. Host said to allocate ,ore = purchase more. What I would like to do is hunt down where I am using the most of it. I have 8 sites (non that are too big). Most of them are wordpress sites.
Would caching help? Not sure where to look to find this out.

We're in the process of setting up our new VPS Server, and we can create a VPS with 256MB memory and with 512MB memory fine, but when creating one with 1GB memory, we get the error:
Could Not Start Vps, Reason: Unable to fork: Cannot allocate memory: Not enough resources to start environment: Container start failed:
Even though the server has 4GB RAM and no other VPS's running. Any ideas?
Thanks.
[Edit]We now seem to get the problem for all our VPS's. I think it may be something to do with the Server not unallocating the memory, as we've provisioned and de-provisioned quite a few Servers

I have a dedicated server with godaddy (I know) and have used a pre-installed mail server product to host a few email accounts. Nothing fancy. My mail server is required to relay through godaddy's servers. A few of my users began complaining about email bounces - specifically "554 message refused". I opened a support ticket 2 weeks ago.
Initially godaddy insisted that the emails contained suspicious phishing links - which they didn't. I incrementally stripped the content of the emails and discovered that it was two simple characters that caused the bounce - left and right square brackets []. I presented this information to godaddy and their response was:
"When sending emails in the future, please make sure that these two brackets are not placed in succession to avoid the email from being bounced"
The problem is that my users are trying to forward or respond to email with embedded content that sometimes contains []. I cannot expect them to strip down their emails.
While acknowledging this issue, godaddy has refused to correct it. Sorry for long-winded explanation but I'm interested in some of your feedback - Does this policy make sense? Why can't they correct it?

I am running two Apache web servers:
- moodle.myCompany.com (Moodle site)
- content.myCompany.com (web server)
I am trying to display a page, from the content site, through an iFrame, on the Moodle site, and am getting a console.log error message of "Refused to display 'http://subdomain.myCompany.com/index.php' in a frame because it set 'X-Frame-Options' to 'SAMEORIGIN'."
I have been doing a lot of reading and it sounds like the X-Frame-Options is deprecated and that I should be controlling things through Content-Security-Policy and frame-ancestors. How do I allow content from a sub-domain to load into an iFrame on my moodle site?

Plask Management inferace error is:
ERROR: Zend_Db_Adapter_Exception: SQLSTATE[HY000] [2002] Connection refused (Abstract.php:144)
First, the datacenter lost power so the server shut off. I assume there is some DB corruption and why the SQL Service won't start.

I've got a VPS which is serving as the main server for a number of sites. Web Server, SSH Server, and Mail Server.
What I've got running:
Apache2, PHP5, MySQL5, Dovecot, Postfix
One of the sites is a growing forum with a MASSIVE photo album. This is the site where I notice the most slowness.
Changing the server software is not an option - Only optimization.
