Solaris 10 SNMP v3 Konfigürasyonu

Admin - Emre Yasar — Mon, 28 Dec 2009 07:56:52 +0000

Solaris 10 işletim sisteminde SNMPv3 konfigürasyonu yapmak için aşağıdaki 3 adımın tamamlanması gerekiyor:

1. /etc/sma/snmp/snmpd.conf dosyasının düzenlenmesi

vi /etc/sma/snmp/snmpd.conf

syscontact, syslocation bilgilerini düzenleyin

rocommunity ve rwcommunity satırlarını #‘leyin

Dosyanın sonuna master agentx satırını ekleyin

2. SNMPv3 kullanıcısının oluşturulması

Aşağıdaki komut kullanılarak snmp kullanıcısı oluşturulur:

/usr/sfw/bin/net-snmp-config –create-snmpv3-user -a “Ş İ F R E” KULLANICI_ADI

3. SNMP serivisinin başlatılması

/usr/sbin/svcadm disable -t svc:/application/management/sma:default

/usr/sbin/svcadm enable -t svc:/application/management/sma:default

SNMP agent’ının çalışdığından emin olmak için /var/agentx konumunda master dosyası mevcut olmalı.

Kontrol etmek için:

ls -al /var/agentx/

total 4
drwx——   2 root     root         512 Dec 24 04:50 .
drwxr-xr-x 54 root     sys         1024 Dec 24 04:28 ..
srwxr-xr-x   1 root     root           0 Dec 24 04:50 master

Unix Tips – How to Find Hardware Information on Solaris

Admin - Emre Yasar — Thu, 10 Dec 2009 18:39:39 +0000

You can find hardware information by typing the command below:

/usr/platform/`uname -i`/sbin/prtdiag -v

For processor information run this command:

/usr/sbin/psrinfo -v

Basic Linux Tips #1 – Argument list too long -

Admin - Emre Yasar — Fri, 20 Nov 2009 11:14:18 +0000

If you are getting an error message as “Argument list too long” while attempting to run a command at Linux shell “find” command will be your lifeguard.

This error message tells you, the directory you are trying to work contains a huge number of files. That’s why the shell can not handle this operation.

Solution is simple. Try taking to pieces your batch. For instance try running cp conf*.txt /tmp instead of using cp * /tmp

If you can’t group the files as above you may use find command with exec option.

emreyasar@testserver:~> cp /srv/www/htdocs/cacti/rra/* /tmp/
-bash: /bin/cp: Argument list too long

At this situation this command will do what you are trying to do:

emreyasar@testserver:~> find /srv/www/htdocs/cacti/rra -name “*” -exec cp {} /tmp \;

You will like using find command with exec option.

It may simplify your works so many times.

Unable to Install VMware Tools for Solaris 8 VM on ESX Server

Admin - Emre Yasar — Thu, 19 Nov 2009 06:54:50 +0000

If you need a Solaris 8 (5.8) running on ESX server you may install OS without any error. But when you try to install VMware Tools after OS installation, strongly probable, you will get an error like this:

./vmware-install.pl

Setup is unable to find the “update_drv” program on your machine. Please make sure it is installed. Do you want to specify the location of this program by hand? [yes]

At this point do not try to locate update_drv on your disk “by hand”. Because you won’t find this at your Solaris 8.

update_drv was released with Solaris 9 included in SUNWcsu package.

But we know that Solaris 8 VM is being supported by vSphere 4.

So we opened a ticket to VMware about this issue. This is the answer of support request:

…according to this links as the guest os guide at the page 160, there is no VMware tools version supported under this version of Solaris 8 then unfortunately you won’t be able to install this package inside this VM.

http://www.vmware.com/pdf/GuestOS_guide.pdf

Solaris 8 is being supported within “experimental” logic yet. That’s why we can’t use VMware tools for Solaris 8.
