Feb 24 13:02:39 soekris apcupsd[1369]: Power failure.
Feb 24 13:02:45 soekris apcupsd[1369]: Running on UPS batteries.
Feb 24 13:41:27 soekris apcupsd[1369]: Mains returned. No longer on UPS batteries.
Feb 24 13:41:27 soekris apcupsd[1369]: Power is back. UPS running on mains.

I must say the UPS with my OpenSolaris laptop and 2 external ZFS disks  on came close to a shutdown because the battery was almost empty.

I will try to post some more soon..

I wanted some backup in case the power went down at home, not that it happens every day or even month but it happens. there was always a problem after such an event, not all the discs were found on my opensolaris (usb disk with a very low spin up time) or it was stuck on the boot archive. So I bought me two of these UPS’es, each for about €80 and they have a usb cable to monitor them! I hooked one to my soekris downstairs wich runs openbsd and one to my backup/media server running opensolaris. here is what I did to configure them from the source on http://www.apcupsd.org/

Installation on OpenSolaris:
First of all, when you plug it in you’ll see this on opensolaris:
Jul  2 20:56:34 OpenSolaris usba: [ID 349649 kern.info]         APC Back-UPS ES 550 FW:828.D3 .I USB FW:D3  3B0???X?????
Now you need to install SUNWgmake and download the usb.h header file

# pkg install SUNWgmake
# cd /usr/sfw/include
# wget http://src.opensolaris.org/source/raw/sfw/usr/src/lib/libusb/inc/usb.h
-> unpack the apcupsd tarball and cd into it.
# ./configure –enable-usb
# gmake
# gmake install
-> cd to the config files in /etc/opt/apcupsd

Installation on OpenBSD:
You’ll get this when you plug it in
ugen0 at uhub0 port 1 “APC Back-UPS ES 550 FW:828.D3 .I USB FW:D3″ rev 1.10/1.06 addr 2

-> unpack the apcupsd tarball and cd into it.
# ./configure –enable-usb
# gmake
# gmake install
-> cd to the config files in /etc/apcupsd

On both operating systems you need to at least have these settings:
UPSCABLE usb
UPSTYPE usb
DEVICE

On OpenSolaris you need to reconfigure before starting apcupsd so do:
# touch /reconfigure && init 6
-> apcupsd will start automatic now, check the status with:
# /etc/opt/apcupsd/sbin/apcaccess status

On OpenBSD you need to edit /etc/rc.local so apcupsd will start automaticly then check the status with:
# /sbin/apcaccess status

Don’t forget to read the manual! a point of intrest:
*BSD: http://www.apcupsd.org/manual/manual.html#known-bsd-usb-issues

What do you think of the result?

We need a few ingredients to get this running, here are my steps:

• First of al the SUNW packages for vscan (you should be able to install them if you haven’t got them)

# pkginfo |grep -i vscan
system      SUNWvscankr                     Virus Scan Service Kernel (Root)
system      SUNWvscanr                      Virus Scan Service (Root)
system      SUNWvscanu                      Virus Scan Service (Usr)

• Install an antivirus daemon, I chose for clamav available from blastwave (i’m not gonna explain how to install this, but in the end you should have a running daemon)

• We need to download c-icap from sourceforge and extract it and then compile it

# export LDFLAGS=”-L/opt/csw/lib -R/opt/csw/lib -lclamav”
# export CC=gcc
# export CXX=g++

# ./configure –prefix=/opt/icap –with-clamav=/opt/csw –with-perl=/bin/perl –with-zlib=/usr/lib –enable-large-files

# make
# make install

• Before we start it we need to configure /opt/icap/etc/c-icap.conf (changes only)

CommandsSocket /tmp/c-icap.socket
User nobody
Logger sys_logger
acl localnet src 192.168.1.0/255.255.255.0
icap_access allow localnet
srv_clamav.MaxObjectSize 100M

And commented out the Viralator portions, since I’m not going to use that.
# And here the viralator-like mode.
# where to save documents
# srv_clamav.VirSaveDir /srv/www/htdocs/downloads/
# from where the documents can be retrieved (you can find the get_file.pl script in contrib dir)
# srv_clamav.VirHTTPServer “http://fortune/cgi-bin/get_file.pl?usename=%f&remove=1&file=”
# The refresh rate….
# srv_clamav.VirUpdateTime 15
# For which filetypes the “virelator like mode” will be used.
# srv_clamav.VirScanFileTypes ARCHIVE EXECUTABLE

• Now we need to make sure this service starts by itself, for this I modified the clamav smf manifest to my own c-icap.xml and startup script

# cp svc-c-icap /var/opt/csw/svc/method/
# chmod +x /var/opt/csw/svc/method/svc-c-icap
# svccfg import c-icap.xml
# svcadm enable c-icap

• Now we can start with the ZFS stuff

# svcadm enable vscan
# zfs set vscan=on Maxtor1T/Data
# vscanadm add-engine datacapsule         (replace datacapsule by the hostname of your server with c-icap (in my case I choose the hostname of the same server!)
# vscanadm get-engine datacapsule
# vscanadm set -p max-size=100M
# vscanadm show
max-size=100M
max-size-action=allow
types=+*

datacapsule:enable=on
datacapsule:host=localhost
datacapsule:port=1344
datacapsule:max-connection=32

• Now we need to test! download the eicar test virus and put it on that zfs volume

# cp /tmp/eicar.com /Maxtor1T/Data/pom

# tail /var/adm/messages
…

vncpasswd /etc/X11/.vncpasswd
chown root:root /etc/X11/.vncpasswd
chmod 400 /etc/X11/.vncpasswd

svcadm restart gdm

I found out gdm will go into maintenance mode after a while, so just do this when this happens

svcadm clear gdm

Now you want bonjour to pick this service up so add this to /etc/avahi/services/rfb.service

<?xml version=”1.0″ standalone=’no’?><!–*-nxml-*–>
<!DOCTYPE service-group SYSTEM “avahi-service.dtd”>
<service-group>
<name replace-wildcards=”yes”>%h</name>
<service>
<type>_rfb._tcp</type>
<port>5900</port>
</service>
</service-group>

and then restart the avahi daemon

svcadm restart avahi-bridge-dsd

and then you should have something like this

here is the list:

Commands
apptrace – for trace of library calls
dtrace – debugger, new in version 10
pargs – get list of arguments and environment variables with which process was started
pfiles – list of file descriptors, associated with process
pgrep – get the PID’s of processes by name i.e. Something like ps -efl|grep -v grep|grep process_name
pkill – send signal to process. For example pkill -9 init
pldd – list dynamic libraries, associated with process, similar to ldd for executable
plockstat – see list of locked by process files. Lock can be mutex i.e. exclusive and reader/writer for shared access
pmap – get memory map (segments) of process
preap – try to kick-off zombie process
prstat – fullscreen view of processes sorted by different criteria, similar to Linux top command
prun – continue hold with pstop process
ps – print process information and status. In Solaris exist SYSV and BSD variants, respectively /usr/bin/ps and /usr/ucb/ps
psig – list signals that can be handled by process
pstack – get backtrace stack of process for debugging purposes
pstop – temporary hold process
ptree – print the tree of processes
pwait – wait till process finish
pwdx – list working directory for process, like pwd command
truss – for trace system calls and signals

Examples

in the above example you can see very clear functions as fprintf(), strcmp(), getenv(), etc.

pargs
# pargs 558
558:    /usr/lib/sendmail -Ac -q15m
argv[0]: sendmail: Queue runner@00:15:00 for /var/spool/clientmqueue

argv[1]: <NULL>
argv[2]: @00:15:00 for /var/spool/clientmqueue
in above example you see arguments for start sendmail as daemon

pfiles
# pfiles 558
558:    /usr/lib/sendmail -Ac -q15m

/var/spool/clientmqueue/sm-client.pid
Here you see list of files as NULL, console log, some PID file. On the top you can see the maximum number of file handlers for this process, with info can be helpful for troubleshooting of application

pgrep
# pgrep named
586
Something like ps -efl|grep -v grep|grep process_name|awk ‘{print $1}’
# ps -e|grep -v grep|grep named|awk ‘{print $1}’
586
pkill
# pgrep named
628
# pkill named
# pgrep named
636
#
As you see named daemon was killed and respawned (with new PID)

Show you system calls done by command and you can see parameters of the function, very good for program execution traces
