Exim, refused: too many connections

Paul Ooi — Wed, 21 Jun 2006 03:02:18 +0000

One of our mailserver having problem last week. It’s caused by the massive connections connected into the server sending out newsletter(large database unstoppable loops) from one host.

2006-06-15 08:50:06 Connection from [201.xx.xx.xx] refused: too many connections
2006-06-15 08:50:20 Connection from [201.xx.xx.xx] refused: too many connections
2006-06-15 08:50:24 Connection from [201.xx.xx.xx] refused: too many connections
2006-06-15 08:50:28 Connection from [201.xx.xx.xx] refused: too many connections
2006-06-15 08:50:32 Connection from [201.xx.xx.xx] refused: too many connections

Exim default allow maximum 20 connections from a host. You can increase the connection in the main configuration file by adding in this line;

smtp_accept_max = 50

Pure-ftpd: account disabled

Paul Ooi — Mon, 19 Dec 2005 09:08:36 +0000

I have configured pure-ftpd using FreeBSD ports(usually compiled from source). After everything have setup, postgresql, db, table, users and etc, it seem like cannot connect into the server with the below message…

Dec 19 16:34:14 server pure-ftpd: (?@60.48.150.26) [WARNING] Can’t login as [takizo]: account disabled

After few hours of checking, I found the cause of the problem is the UID and GID I set was low than 1000, if you have the similar problem, try to set a higer UID and GID. Better in the range of 5000(my own opinion).

All the best

VMWare Network on Mac OS X x86

Paul Ooi — Sat, 15 Oct 2005 01:40:55 +0000

How to make your Mac OS X x86 network works with VMWare Workstation???

After Mac OS X has been installed on VMWare Workstation, you will found that the network is not working or the network card it’s not recognize by Mac OS X. You can get the network driver here and follow the instruction below.

Select the ISO file you have downloaded as your CDROM drive

Create a new folder on Desktop(for example network), copy the files from the “CDROM” into the new folder.

Open up the terminal, navigate the to driver folder, run install.sh file and reboot

After reboot, I _think_ your network is working now.(bridge,nat or host also work). Hope it helps. For more information and support please visit the driver’s website
