====== RNSanchez's notes and plans ======

I'm Ricardo Nabinger Sanchez, a Computer Scientist living in south-Brasil {flag-br} (GMT -0300 timezone).  Feel free to contact me even if it's not related to %%FreeBSD%%.

Email/Jabber: <rnsanchez@gmail.com>, and <rnsanchez@wait4.org>\\

PGP key: [[http://rnsanchez.wait4.org/pubkey.asc]]

Interests:

  * Operating Systems Design and Implementation
  * Network monitoring (RMON2) and management (SNMP)
  * Optimizations (reducing overhead)
  * (Low-level) Code generation and improvement
  * MIPS architecture

===== SNMP =====

Currently using, learning and trying to help with [[http://people.freebsd.org/~harti/bsnmp/|BSNMPD]] development,
in contact with ShteryanaShopova, HartiBrandt and VictorCruceru.

My plans are to implement:
  * [[EtherLike-MIB]] ([[http://www.ietf.org/rfc/rfc3635.txt|RFC-3635]])
  * DISKSTORAGE-MIB

DISKSTORAGE-MIB should provide information with greater detail than what is available through
[[http://www.ietf.org/rfc/rfc2790.txt|HOSTRESOURCES-MIB]],
specifically to UNIX environments (perhaps BSD or even %%FreeBSD%% specific).  It was not created yet, btw.

More details to come, and also at [[http://rnsanchez.wait4.org/soc/proposta.txt]], which is my original
(and not selected) proposal for Google's Summer of Code 2006.

You can check [[BsnmpTODO]] for further info on what's coming next in BSNMPD.

==== BSNMPD Patches ====

| [[http://rnsanchez.wait4.org/FreeBSD/bsnmpd/fix_some_segfaults.diff|contrib/bsnmp/gensnmpdef]] (2006-05-30) | Fix some segfaults that occur when a required module is not found while processing user-requested modules.  Others segfaults remain, as libsmi sometimes does not return NULL when some required module was not found.  Perhaps a complete fix depends on a libsmi fix too. |
| [[http://rnsanchez.wait4.org/FreeBSD/bsnmpd/remove_-MIB.diff|ATM and NETGRAPH MIBs]] (2006-05-30) | Fix "module BEGEMOT-{ATM,NETGRAPH}-MIB not found" for BEGEMOT-ATM-FREEBSD-MIB.  HartiBrandt or VictorCruceru probably will come up with a better solution. :) |

===== Miscellaneous Areas of Interest in FreeBSD =====

These are topics I plan to investigate:

  * BSD-licensed ELF tools: because of my final project, I'm getting very used to ELF files, and feel able to help implement BSD-licensed tools for ELF files, like ''%%readelf%%'', (multi-archicteture capable) ''%%objdump%%'', and much others, using JosephKoshy's libelf.
  * CPU accounting and ''%%top%%''(1) + ''%%ps%%''(1): I can't find what processes are eating CPU, and don't understand why (UP machine with UP kernel).
  * ''%%re%%''(4): my RTL8029S giga-ethernet NIC doesn't work on 6.1-RELEASE.  There were lots of commits for it, but I couldn't test it yet, and if I try to use it, sometimes it doesn't work.  6.1 is "old" right now, but...

The list is much longer, but these are the ones I'm //definitely// going to investigate.
