небольшой патч для увеличения коннектов до 128 ( по дефолту 16)patch-uopt
положить в /usr/ports/net/udpxy/files/patch-uopt.h

итак понадобилось мне на стареньком сервере добавить модуль php

но вот ведь незадача порты уже свежие =(

немного погуглив нашел решение: Portdowngrade

итак приступим…

cd /usr/ports/ports-mgmt/portdowngrade/

make DEFAULT_CVS_SERVER=»:pserver:anoncvs@anoncvs.manov.su:/home/ncvs» install clean

rehash

сервер anoncvs можно выбрать другой

ps: надо будет зеркало сделать ибо cvsup есть уже

теперь запустив portdowngrade lang/php5 увидим

portdowngrade 0.6 by Heiner Eichmann
Please note, that nothing is changed in the ports tree
unless it is explicitly permitted in step 6!

Seeking port lang/php5 …

Found several matches:
1: lang/php5
2: lang/php5-extensions

Please choose one: 1

Downgrading port: lang/php5

Step 1: Checking out port from CVS repository
CVS root directory: :pserver:anoncvs@anoncvs.manov.su:/home/ncvs

Step 2: Reading the port history from the CVS repository

Step 3: Analyzing the port history from the CVS repository

Step 4: Load port version numbers and present results
