Getting started using Solaris part 3

Examples

    Let's login in to the system:

$ ssh root@192.168.8.128 
Password: 
Last login: Mon Mar 31 11:39:29 2008 Sun Microsystems Inc. SunOS 5.11 snv_70b October 2007
#

    Next will be interest to check the user we are:

# id 
uid=0(root) gid=0(root)

    See where we are (path)

# pwd 
/

    Check the values of some variables

# echo $PATH "\n" $TERM 
/usr/sbin:/usr/bin 
cygwin

    set the value of variable TERM

# TERM=vt100;export TERM

    List the content of current directory

# ls -l 
total 346 
lrwxrwxrwx 1 root root 9 Nov 1 12:20 bin -> ./usr/bin 
drwxr-xr-x 6 root sys 512 Nov 1 13:00 boot 
drwxr-xr-x 2 root root 512 Nov 6 11:07 cdrom 
drwxr-xr-x 67 root sys 4096 Nov 1 13:31 dev 
drwxr-xr-x 2 root sys 512 Mar 31 11:38 devices 
drwxr-xr-x 91 root sys 4608 Mar 31 11:40 etc 
<SNIP> 
drwxr-xr-x 4 root root 512 Nov 1 12:20 system 
drwxrwxrwt 6 root sys 299 Mar 31 11:39 tmp 
drwxr-xr-x 38 root sys 1024 Nov 1 13:07 usr 
drwxr-xr-x 44 root sys 1024 Nov 5 14:35 var

    go to directory using absolute path and the relative path

# cd /var/adm 
# cd ../tmp 
# pwd 
/var/tmp

    examine the content of file

# cat /etc/nsswitch.conf
# CDDL HEADER START
#
# The contents of this file are subject to the terms of the
# Common Development and Distribution License (the "License").
# You may not use this file except in compliance with the License.
<SNIP>
passwd: files
group: files
hosts: files
dns # Added by DHCP
ipnodes: files
networks: files
protocols: files
netmasks: files
bootparams: files

    Let see the IP settings

# ifconfig -a
lo0: flags=2001000849<UP,LOOPBACK,RUNNING,MULTICAST,IPv4,VIRTUAL> mtu 8232 index 1
        inet 127.0.0.1 netmask ff000000
e1000g0: flags=1000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4> mtu 1500 index 2
        inet 10.0.2.10 netmask ffffff00 broadcast 10.0.2.255
        ether 8:0:27:13:f7:38


    and routing table

# netstat -rn

Routing Table: IPv4
  Destination           Gateway           Flags  Ref     Use     Interface
-------------------- -------------------- ----- ----- ---------- ---------
default              10.0.2.2             UG        1          0
10.0.2.0             10.0.2.10            U         1          0 e1000g0
224.0.0.0            10.0.2.10            U         1          0 e1000g0
127.0.0.1            127.0.0.1            UH        1         40 lo0


    Get the list of opened ports

# netstat -a |grep LISTEN
      *.sunrpc             *.*                0      0 49152      0 LISTEN
      *.ssh                *.*                0      0 49152      0 LISTEN
<SNIP>
localhost.32807            *.*                0      0 49152      0 LISTEN
localhost.32808            *.*                0      0 49152      0 LISTEN
localhost.32809            *.*                0      0 49152      0 LISTEN
localhost.32810            *.*                0      0 49152      0 LISTEN
      *.ssh                             *.*                             0      0 49152      0 LISTEN
      *.32794                           *.*                             0      0 49152      0 LISTEN


    stop the sendmail (because we will not use this server for this purpose)

# svcadm disable sendmail

    and check again for daemon listening on port 25

# netstat -an|grep 25|grep tcp
#



Conclusion

Above you see only very brief overview of the functions, commands and details of Solaris operating system. If you need more indeep knowledge go to SUN doc site Solaris 10 Operating System, search for information, spread in Internet. check and apply for courses in your area, play with x86 version, using virtual machine, ask questions.
