Client Stopped Connection Before Send Mmap

Apr 5, 2007

I've got a one month stable setup running a cpanel + apache 1.3.x and suddenly starting yesterday i get these errors from time to time in the log from various IPs:

(104) Connection reset by peer: client stopped connection before send mmap completed

(32) Broken pipe: client stopped connection before send mmap completed

send mmap timed out

Googling shows people guessing at everything from mysql errors to the visitor clicking a link on a partially showing page before it's completed.

Anyone with more clear insight? Mysql shows no apparent errors.

Site is a heavily loaded wordpress setup with mod_gzip the only major addition to apache. Also running a firewall for a week now. Errors did not show up until yesterday.

Plesk 12.x / Linux :: FTP Stopped Connecting Via Client?

Apr 30, 2015

The FTP on my VPs running centos 6.6 and plesk 12.0.18 Update #44 has stopped allowing FTP conections via filezilla or dreamweaver. My tech knowledge with server management outside of the gui is minimal but i have done the following. Checked that the firwall is allowing ftp traffic through the GUI in plesk.

restarted xinetd and checked status
[root@367549 ~]# service xinetd status
xinetd (pid 11707) is running...
[root@367549 ~]# lsof -i tcp:21
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
xinetd 11707 root 5u IPv6 682472 0t0 TCP *:ftp (LISTEN)

Then tried the following
[root@367549 ~]# ftp localhost
-bash: ftp: command not found

But i can connect via telnet on port 21

when trying to use +dreamweaver or filezilla i get the following. This may be due to one or more of the following reasons: - The network cable is unplugged or the network is down. Please verify that the network cable is connected and that the network is up. - The FTP server is down. Please verify that you can connect to the FTP server using another FTP program. - The FTP host name is incorrect. Please verify that the host name is correct in the Site definition dialog box. - Accessing the server requires proxy settings that aren't properly set. Please verify that the proxy settings in the Site category of the Preferences dialog box are properly set, and that the Use Proxy option in the Site definition dialog box is selected. - You may need to connect to the server using a different port than the one provided. Please specify the correct port in the box provided.

Error: The data connection could not be established: ETIMEDOUT - Connection attempt timed out
Error: Connection timed out after 20 seconds of inactivity
Error: Failed to retrieve directory listin.

What to do and why after no change this just stopped working when ive been using ftp on this server previous.. the company that i brought the vps from have no intrest and tell me its unmanaged.

SMTP Connection Has Stopped Working

Jul 9, 2008

I have been having great trouble sending mails from my local Thunderbird/Windows client to my Debian/Exim-server via TLS/SMTP.

I am no expert on TLS and SMTP, but I managed to create a server certificate and set up a secure (TLS) connection more than a year ago, and it has been working fine until it suddenly stopped working a couple of weeks ago.

Sending to external addresses from web pages still works fine, the problem seems to be in the SMTP connection. If I try to "telnet xxx.xxx.xxx.xxx 25" I get no reply whatsoever (it seems to connect but it just gives me a blank screen with a blinking cursor) and I am wondering if there is a firewall issue or if I am simply not running the right daemon to listening for incoming SMTP connections...

POP continues to work fine with teapop/stunnel enabled.

I am running Exim 4.63-17 on Debian Etch. I configured Exim to be of the type "internet site; mail is sent and received directly using SMTP"

==============================
Firewall shouldn't be a problem (?):

debian:~# iptables -L
Chain INPUT (policy ACCEPT)
target prot opt source destination
Chain FORWARD (policy ACCEPT)
target prot opt source destination
Chain OUTPUT (policy ACCEPT)
target prot opt source destination
==============================

I really don't know what to do. I have tried running:
tail -f /var/log/daemon.log

Which responds when I access my mail using POP but not when I try to send using SMTP.

Apache Restarts After Client Send Request With No Header

Jul 14, 2008

I have a client who's Apache on a CPanel based VPS keep's restarting.

In the error log we recieve two of these lines

"client sent HTTP/1.1 request without hostname (see RFC2616 section 14.23): /w00tw00t.at.ISC.SANS.DFin "

Then the Apache will restart.

I have looked around and found some threads about this problem, but none explaining how to fix this.

Dec 31, 2013

i want to configure Apache so that it receives a client certificate, an passes it to another server.I'm using:

Plesk 12.x / Linux :: Client Intended To Send Too Large Body

May 11, 2015

I have been using Plesk for a while on my server, but this is the first time that I need to set up large files uploading for a client who requires to upload via a form files that are larger than 128MB (but less than 400).The issue I've been seeing is that whenever the user tries to upload a file greater than 128MB I see an error on the proxy_error_log that says:

2015/05/10 21:46:18 [error] 31224#0: *9 client intended to send too large body: 175420278 bytes, client: XX.XX.XX.XX, server: myserver.com , request: "POST /admin/products/1 HTTP/1.1", host: "myserver.com", referrer: "referrer"

I've been googling this issue and everything points to the nginx configuration (PHP parameters have already been set up). I proceeded to change the configuration of /etc/nginx/nginx.conf to include

http {
...
client_max_body_size 400M;
...
}

HOWEVER (and this is where I'm stuck) after restarting the nginx service, the fille /etc/nginx/plesk.conf.d/vhosts/myserver.com.conf continues to hold the value:

server {
...
client_max_body_size 128m;
...
}

Modifying this file to change the 128m to 400m does not make a difference.

Nsplayer Must Be Stopped

Sep 24, 2007

i have been around the internets trying to figure out how to stop this menacing problem and i really have come to just a lot of dead ends.

my issue is that i want to block people using something called nsplayer from ravaging my bandwidth. every day there are at least 300 or so entries from people using this piece of software which is causing me to blow through about 20 gigs a day instead of around 5-7 gigs. the fine support folks at imountain went out of their way and wrote a htaccess script but alas that isnt helping that much. so, what i have been doing is just banning each individual ip through htaccess and sometimes it works and sometimes it doesnt.

my site is in my profile.

is there anyway to block this completely?

here is an example of one of my log entries.

79-65-96-136.dynamic.dsl.as9105.com - - [23/Sep/2007:19:33:06 -0700] "GET /debaser/vol.%204/14%20Wish%20You%20Were%20Here.mp3 HTTP/1.1" 200 803868 "-" "NSPlayer/11.00.6000.6324 WMFSDK/11.00.6000.6324"

i dont know if it matters, but i am using h-sphere and indexing is turned off.

CPanel Stopped Working In Vista

Jan 4, 2008

Yesterday I could reach all of my cPanels on a Vista laptop; today they all time out. I can reach them with other computers. It doesn't matter if I go to mysite.com/cpanel or mysite.com:2082. I even added a port 2082 under Windows Firewall; no change. I'm not using any 3rd party firewalls. I did install a bittorrent client last night, then uninstalled it when it didn't work.

Email Stopped Working On Server

Apr 14, 2007

Recently I noticed that I was not getting any email on my server.
Server is running CentOS

When I send email to myself I am not getting anything and then it bounces back several days later saying the server is not responding.

When I check on Dnsstuff.com I get the following:
Trying to connect to all mailservers:

mail.webzila.com. - 216.32.77.68 [Could not connect: Could not receive data: Operation timed out.]

[Note that if your mailserver takes over 30 seconds to respond, our test will timeout, even though real mailservers will wait longer]

I tried turning mail services OFF and then ON again in Plesk but that didnt help.

Munin Stopped Reporting Eth0 After Reboot

Apr 30, 2008

I rebooted my server and now munin is not showing any eth0 traffic. All other graphs are fine. I can see there is a ton of apache accesses so there is definitely eth0 traffic. Munin logs report no errors. I restarted munin and munin-node. I even did 'yum remove munin munin-node' and reinstalled again but it still doesn't work for eth0.

Remote Desktop Suddenly Stopped Working

Jan 28, 2008

I have a server that I access through remote desktop. Suddenly I am getting the message "Remote Desktop Disconnected: The computer can't connect to the remote computer." when using Remote Desktop.

It was working a few minutes ago.

A while ago I suspected that someone knew the password for the box. I did change it at the time, and thought the issue was solved. Is it possible to turn off remote desktop remotely (whilst using remote desktop).

Power cycling the server isn't making any difference.

Any other options other than putting in a support request at the host?

Mailbox Allowance? My Incoming Emails Have Stopped Coming In

Sep 3, 2008

But with my current host, my incoming e-mails have stopped and have done quite a lot of times, If I send an e-mail to myself from another acount, it gets bounced back.

When I'm searching for hosts, I can't see any info on mailbox allowance.

I'm using Outlook to download all my e-mails.

I don't know why they are stopping and I can't find out from the person who got the host from me, in the past he said something about me having to delete e-mails. But this would come back to mailbox space which no hosts seem to advertise, unless it goes under webs space.

If my mailbox is full or ran out of space, does anybody have any recommendations for a host that offers a good amount of mailbox space.

Another question, am I limited to the amount of e-mails I can send with some hosts? I'll be sending out Newsletters to 600+ people each month.
