FreeBSD View Memory Usage

November 17, 2014 Leave a comment

Get memory from dmesg:

[root@freebitch10 /]# dmesg | grep memory
real memory = 134152192 (127 MB)
avail memory = 102039552 (97 MB)

To see swap memory only

[root@freebitch10 /]# swapinfo
Device          1K-blocks     Used    Avail Capacity
/dev/ada0p3        314368    13052   301316     4%

Total physical memory in the system (with sysctl):

[root@freebitch10 /]# sysctl hw.physmem
hw.physmem: 110563328

Another way is to use top command

[root@freebitch10 /]# top -n | grep Mem
Mem: 3704K Active, 35M Inact, 41M Wired, 940K Cache, 20M Buf, 20M Free

Just to see free memory

[root@freebitch10 /]# top -d 1|grep '^Mem:'|cut -d ',' -f 6
 20M Free

You can also install sysinfo (utility used to gather system configuration information)

[root@freebitch10 /]# pkg install sysinfo

The following 1 packages will be affected (of 0 checked):

And get the memory information:

[root@freebitch10 /]# sysinfo mem

Freebsd 10 pkg manager

With the fresh install when you try to install any package you will get something like: No package found

To solve this issue:

# cp /usr/local/etc/pkg.conf.sample /usr/local/etc/pkg.conf
# pkg update

or

/etc/pkg/FreeBSD.conf

replace -> url: “pkg+http://pkg.FreeBSD.org/${ABI}/latest”
with      -> url: “pkg+http://pkg.FreeBSD.org/${ABI}/release_1”

Freebsd Installing ports via distcc

September 5, 2011 Leave a comment

Our main machine is freebsd 8.2 on ibm t22 which sucks at compiling anything:

CPU: Intel Pentium III (696.97-MHz 686-class CPU)
Origin = "GenuineIntel"  Id = 0x68a  Family = 6  Model = 8  Stepping = 10
Features=0x383f9ff<FPU,VME,DE,PSE,TSC,MSR,PAE,MCE,CX8,SEP,MTRR,PGE,MCA,CMOV,PAT,PSE36,MMX,FXSR,SSE>
real memory  = 402653184 (384 MB)
avail memory = 379080704 (361 MB)

So what we’ll do is;

Use distcc and compile ports with couple of machines (kind of clustering) in our network and hope it will be much more faster…..

Distcc lets you to compile any source across the network with as many machines as you want. Distcc has 2 modes pump and plain.

Plain mode:

With plain distcc, the preprocessor must always run locally because it needs to access various header files on the local machine
which may not be present, or  may  not be  the  same, on the volunteer.

Pump Mode:

In pump mode, distcc runs the preprocessor remotely too.  To do so, the preprocessor must have access  to  all  the files  that it would have accessed if had been running locally.  In pump mode, therefore, distcc gathers all of the recursively included headers, except the ones that are default system headers, and sends them along with the source file to the compilation server

We will use plain mode. Main machine freebsd other machines various linux servers. Mix and match……

Under freebsd we will also use bsdadminscripts which makes life a lot of easier when dealing with distcc with ports compile

If you do not have port tree installed than:

[root@freeslut ~]# portsnap fetch
[root@freeslut ~]# portsnap extract

if you already have ports:

[root@freeslut ~]# portsnap fetch update

install distcc:

[root@freeslut ~]# cd /usr/ports/devel/distcc
[root@freeslut ~]# make install clean

install ccache:

[root@freeslut distcc]# cd ../ccache/
[root@freeslut distcc]# make install clean

install bsdadminscripts:

[root@freeslut ccache]# cd ../../sysutils/bsdadminscripts/
[root@freeslut ccache]# make install clean

create buildflags.conf file

[root@freeslut ccache]# cp /usr/local/etc/buildflags.conf.sample /usr/local/etc/buildflags.conf

Add fallowing to /etc/make.conf (this tells make to use bsdscripts directives)

[root@freeslut ccache]# cat /etc/make.conf
# /usr/local/etc/buildflags.conf
BUILDFLAGS= /usr/local/share/bsdadminscripts/buildflags.mk
.if exists(${BUILDFLAGS})
.include "${BUILDFLAGS}"
.endif

distcc is looking 3 places before it connects to any servers these are in order of:

A “host list” tells distcc which machines to use for  compilation. In order,  distcc  looks  in  the  $DISTCC_HOSTS environment variable, the user’s $DISTCC_DIR/hosts file, and the system-wide host  file.   If  no host list can be found, distcc emits a warning and compiles locally.

freebsd 8.2 does not create distcc hosts file and folder so we will create it:

[root@freeslut ccache]# mkdir /usr/local/etc/distcc/
[root@freeslut ccache]# touch /usr/local/etc/distcc/hosts

Define hosts 1:

Lets add some hosts to connect:

[root@freeslut ccache]# echo 192.168.1.129/24 > /usr/local/etc/distcc/hosts
[root@freeslut ccache]# echo 192.168.1.127/24 >> /usr/local/etc/distcc/hosts

Add check hosts:

[root@freeslut ccache]# distcc --show-hosts
192.168.1.129/24
192.168.1.127/24

Define hosts 2:

Also if you have your hosts links in your /etc/hosts file

[root@freeslut ccache]#cat /etc/hosts
----------
192.168.1.129    kuku kuku.xxx-xx.com
192.168.1.127    tirtil tirtil.xxx-xx.com
192.168.1.109    sales sales.xxx-xx.com
----------

You can define your hosts with fallowing command (within bash shell)

[root@freeslut ccache]# export DISTCC_HOSTS="tirtil sales kuku"

I prefer this way because somehow other one is not working for me (Define host 1 system)

[root@freeslut ccache]# distcc --show-hosts
tirtil
sales
kuku

ok under linux machines distcc is seperated to 2 files server and client (im using fedora)

so install them by:

[root@tirtil ~]# yum install distcc distcc-server ccache

Edit server conf file to allow clients to connect

[root@tirtil ~]# vim /etc/rc.d/init.d/distccd

i’ll allow full 192.168.1 network so i add  “–allow 192.168.1.0/24” under options:

distccd editing

save it and start the service:

[root@tirtil ~]# service distccd start
Starting distccd (via systemctl):                          [  OK  ]

Repeat this step on every machine you want to use for compiling ports.

We are done with setup so lets start to compile something, on freebsd machine :

[root@freeslut ccache]# cd ../../www/apache22/
[root@freeslut ccache]# make

And in another console run fallowing command to see distrubution list:

[root@freeslut ~]# distccmon-text 5

77701  Compile     listnode.tmp.freeslut.xxx-x                   tirtil[0]
77745  Compile     abstract.tmp.freeslut.xxx-x                localhost[0]
77759  Compile     bufferobje.tmp.freeslut.xxx-x                   kuku[0]
77811  Compile     floatobjec.tmp.freeslut.xxx-x                 kaypak[0]

so thats all folks……………

More about ports

September 3, 2011 Leave a comment

i was thinking to write about distcc before i got this new computer w i5 processor…..When i was running my ibm t22 distcc really seamed like decent solution but now….unless you have a bluefire (http://www2.cisl.ucar.edu/docs/bluefire/system-information-overview) in your network distcc is useless against ports system…

Did i mention “Fuck port system!!!!!!!!!”

Update: Probably you’ll need couple of bluefire systems in your network to make this fat bitch compile faster…..

Port system sucks

September 3, 2011 Leave a comment

This port system is really fucked up situation…What ever people say its useless….

intel icore 5 2.3 Ghz 8 gb ram

CPU: Intel(R) Core(TM) i5-2410M CPU @ 2.30GHz (2294.80-MHz 686-class CPU)

make vim takes longer than 2 hours…i know it has depencies and such but seriously fuck it..
