Whenever you do a ping or traceroute in Cisco IOS it tells you to “Type escape sequence to abort”. It would be handy if the IOS actually told you what the escape sequence is. To abort type CTRL-SHIFT-6 twice.
I’ve been using GnuCash for some time and have found it to be a great product. Where GnuCash falls short, in my opinion, is it doesn’t provide for scheduled automatic invoice generation. Additionally creating custom invoices involves learning Scheme which personally I don’t have time to get my head around. So I set out to fix these 2 issues using the tools I know well, namely MySQL, perl, and good old HTML. This post will cover custom invoice generation to html and pdf, and emailing the results to the customer using a template. GnuCash scheduled automatic invoice creation will be covered in another post in the near future.

For quite some time I’ve been getting duplicate sources.list entry errors when performing software updates/installs on our Ubuntu server. The reason I hadn’t done anything about it was this error is just an annoyance and wasn’t impacting on the servers performance. The problem stems from this server being used for development and testing, so it is always being upgraded to the latest Ubuntu release. This even includes beta releases. The server started out life on Ubuntu 9.04 release and now is sitting on Ubuntu 12.04. Read more about The simple way to fix Ubuntu duplicate sources.list entry errors …
If you intend to run an internet facing FTP server you have 2 options for FTP, active or passive. The easiest option for an FTP server administrator is the active mode. In active mode the client makes a connection to the server on port 21. The server then makes an outbound connection on port 20 to the client on a random port (>1023) for data transfer. So for the FTP server administrator the only port redirection required is port 21, and firewall access required is port 21 inbound and 20 outbound. While this is great for the FTP Server admin your clients will most likely fail to achieve any data transfer. This is because most clients will have some form of firewall in place which will prevent the server from making the connection to the random port.
