Tuning /etc/sysctl.conf

2013-10-14 Thread Carlos Jacobo Puga Medina 
Hi people,

I'm very interested to tuning /etc/sysctl.conf according to the
specifications of my PC. I've been reading some guides [1], tutorials
[2-3], QA [4] and the FreeBSD Handbook's related section 12.12 Tuning with
sysctl(8), but I think it's much more convenient if I contrast it with
other examples or experienced users.

Here is my relevant info outputs for help to improve the sysctl(8)
variables.

Hi Steve,

I use it as a paticular desktop PC. Well, if you need more details about
it, please, let me know.
What do you think about current tuning?

Thanks

iconv conversion fails

2013-09-04 Thread Carlos Jacobo Puga Medina 
Hi folks,

I have a problem with the iconv(1) conversion, despite it supporting the
encoding charset ISO-8859-1 it throws the following error:

unsupportedrsion from ISO-8859-1
iconv: try 'iconv -l' to get the list of supported encodings

iconv(1) on BSD has:
