I have a vb forum that keep sending me email errors: max_user_connections. I've increased the setting in my.cnf to 2000 (max allowance) and still getting error.
What's possibly are the other reasons? Anyone has any idea?
When i try and connect to my server via SSH it replys with an error saying;
Server refused to allocate pty
stdin: is not a tty
My host's knowledge base says to click "Fix Centos Dev" but this doesn't work...
I have two servers (one for apache and one for SQL) where both are in the same DC. I looked at the BW graph and saw that the SQL server has pulled approx 4TB BW on the internet the last 30 days.
Since both are in the same DC, it would be better to run it via the network since it has free lan traffic compared to wasting a lot of "internet BW".
I'm currently using sqlservername.domain.com in the SQL connection string, but when I tried with the IP, the php script stalls for 30 seconds and then reports: "Can't connect to MySQL server on 'hostname' (4)".
Could this be a iptables issue? I also tried to add the apache IP in the "Additional MySQL Access Hosts" from cPanel, but that didn't help much.
Servers:
Apache - 10.1.0.xxx
SQL - 10.1.1.xxx
If I'm not mistaken, if the subnet isn't set to 255.255.255.0, both servers should be within range.
I have a problem to send email using qmail to 1 company.
eg : mail@mycompany.com to mail@companytwo.com
The problem happen just when i send email to this companytwo only....
when i run this command to check
tail -f /var/log/qmail/send/current
i found this error appear 'Sorry,_I_wasn't_able_to_establish_an_SMTP_connection'
How to i fix this problem....
Why does this happen? How should I fix it? Can I just restart the sql service? How to do so?
This either means that the username and password information in your wp-config.php file is incorrect or we can't contact the database server at localhost. This could mean your host's database server is down.
* Are you sure you have the correct username and password?
* Are you sure that you have typed the correct hostname?
* Are you sure that the database server is running?
If you're unsure what these terms mean you should probably contact your host.

I want to know what is my ram site and why that all errors?
We are hosting a Git server (using Gitolite v3). Our users are interacting with git over an https connection. Here's the relevant versions of software:
Apache 2.4.6
OpenSSL 1.0.1e-fips
Red Hat Enterprise Linux Server release 6.5 (Santiago)
git version 1.8.5.3 (Server Side)
git version 1.9.2.msysgit.0 (Client Side)
Users sometimes encounter an SSL error message when attempting to run git commands that talk to the server (e.g. clone, push, pull). The error message is "Unknown SSL protocol error in connection to servername:443". Users can usually simply try the command again, and it will then work successfully.
I've managed to capture a bit more output by setting the GIT_CURL_VERBOSE flag, see output below.
Code:
* Couldn't find host servername in the _netrc file; using defaults
* Adding handle: conn: 0x2587c40
* Adding handle: send: 0
* Adding handle: recv: 0
* Curl_addHandleToPipeline: length: 1

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 got this error :

I have a client with a dedicated server running. Spec below.
The problem I am having is with incoming email. When I set up a new email account it can take about 10 attempts to log on to the incoming mail server. Once it has connected it will be ok for a short while then I will get a connection error and no emails will come through.
This is happening across all platforms, PC / MAC / iPhone and iPad.
I am a web designer with limited knowledge of the setting up of the server and was looking to set up email server within plesk.

View 13 Replies View RelatedI am on a VPS server and want to know in high traffic conditions how many connections per IP address can come... because on my site connections per IP going to 300 and mostly around 100.
But these are fluctuating and from different locations... everytime.. so dont think as a Dos but so many connections per IP makes my server down for few minutes until connections dont go down.
how many maximum connections per IP will be fine... for a little popular site.
I have a directory, named downloads/
I have some huge files for download in this directory.
now, when our users trying to download files from this folder with flashget (or dap or ...) this programs create 5 connection to that files! so If a user trying to download 5 files , he have 25 connection to my server!
How can I limit connection per Ip on file in this folder ?
Today i get alert from server provider saying my server is under attack, i check netstat and found too many connections.

I have rebooted the server and now server is normal.
I disabled yum on the server. Some days back, i have same problem with another server, server have too many connection to one of the yum respositry IP. The OS is CentOS 5.1
This is an error that dns report spat out to me. I have the firewall disabled as of now so I don't understand why packets would be blocked..if they are being blocked. From what I can tell, I can get to the server and resolve no problem...but could that stop other dns servers from connecting to it? I recently moved my cpanel box to another location in the LT datacenter in order to get on a different subnet - the previous one was a spam list nightmare. All IP's have been changed over and such...is this just cached from like the 14 hours I was down (ouch!) or is this still happening? I mean...its able to look up a records and it can get the mx servers...
error: Our local DNS server was unable to get your MX record. This usually means that a firewall in front of your DNS server is interfering. For example, it may be blocking DNS packets from low source port numbers (ours is often in the 1024-1030 range). Firewalls should never block DNS queries based on the source IP address; otherwise, it is guaranteed that legitimate queries will be blocked. This specific lookup must be cached, so a recent change may not be reflected.
