lsof alternative in Solaris

User creations in Solaris 11

To my surprise Solaris 11 does not create new user's home directory by default.


[email protected]:~# su - testuser
su: No directory!
[email protected]:~# pwck
Login directory not found


[email protected]:~# useradd -m testuser
80 blocks

In the process, I learned something new about the su command. In Linux, when switching from root to a limited user, I used to do the following:

[[email protected] ~]# su tony -

What I did not know was that the above command will indeed load up the PATH of tony, but it will also append root's PATH at end of it which is kind of scary. In theory the command that I wanted to use was `su - username`, luckily this feature is not supported in Solaris 11.

[email protected]:/# su testuser -
bash: /root/.bashrc: Permission denied


Installing Nagios Remote Plugin Executor in Solaris 11

Install gcc

pkg install pkg://sfe/runtime/gcc pkg://sfe/sfe/developer/gcc

Install system headers (not really sure if all listed were necessary):

pkg install SUNWhea SUNWbinutils SUNWarc SUNWgcc SUNWgccruntime SUNWlibsigsegv SUNWgm4 SUNWgnu-automake-110 SUNWaconf

Update your PATH:

export PATH

Manually create nagios user account, home directory, group, and assigned him a password.

mkdir -p /usr/local/nagios
useradd -d /usr/local/nagios -m nagios
groupadd nagios
usermod -G nagios nagios
passwd nagios

Download, extract, compile and install nrpe.

tar -xvf
cd /opt/nrpe-2.13
./configure --with-nagios-user=nagios --with-nagios-group=nagios
make install
make install-daemon-config
cp src/check_nrpe /usr/local/nagios/libexec

Update permissions.

chown -R nagios:nagios /usr/local/nagios/

Add the following entry to /etc/services

nrpe 5666/tcp # NRPE

Add the following entry to /etc/inetd.conf

nrpe stream tcp nowait nagios /usr/sbin/tcpd /usr/local/nagios/bin/nrpe -c /usr/local/nagios/etc/nrpe.cfg -i

Convert and add the new legacy inetd entry to SMF.

inetconv -e

Creating large files in Solaris for testing purposes

In the Linux world, I use the dd utility to create files that need to be a certain size. Even though it works perfectly fine, its kind of annoying figuring out the output file's size of the file. This is because the size is based on the "bs" (block size) value and the total number of block size "count" together.

For example, the following dd command creates a 300 mb file called 300mb-test-fil. Each block size will be 1000 bytes, and I want of a total of 300,000 blocks.
Formula: ( (1000 x 300000) / 1000000 )

[[email protected] ~]$ dd if=/dev/zero of=300mb-test-file bs=1000 count=300000
300000+0 records in
300000+0 records out
300000000 bytes (300 MB) copied, 2.0363 s, 147 MB/s

Luckily in the Solaris world this can be easily accomplished using the mkfile utility, without doing any conversion.
I used the mkfile utility to easily create test disk files to experiment with ZFS.

[email protected]:~# mkfile 300m testdisk1
[email protected]:~# mkfile 300m testdisk2
[email protected]:~# ln -s /root/testdisk1 /dev/dsk/testdisk1
[email protected]:~# ln -s /root/testdisk2 /dev/dsk/testdisk2
[email protected]:~# zpool create tonytestpool mirror testdisk1 testdisk2
[email protected]:~# zpool status tonytestpool
pool: tonytestpool
state: ONLINE
scan: none requested

tonytestpool ONLINE 0 0 0
mirror-0 ONLINE 0 0 0
testdisk1 ONLINE 0 0 0
testdisk2 ONLINE 0 0 0
