svcs
___________________________

Reports status of service(s); useful for debugging service issues

svcs with -x option, displays the states of services which:

• are enabled, but not running
  
• are preventing another enabled service from running

-v option along with -x, displays verbose information

eg.,

% svcs -x
svc:/application/print/server:default (LP print server)
 State: disabled since Tue Mar 22 01:51:18 2005
Reason: Disabled by an administrator.
   See: http://sun.com/msg/SMF-8000-05
   See: lpsched(1M)
Impact: 2 dependent services are not running.  (Use -v for list.)

% svcs -xv
svc:/application/print/server:default (LP print server)
 State: disabled since Tue Mar 22 01:51:18 2005
Reason: Disabled by an administrator.
   See: http://sun.com/msg/SMF-8000-05
   See: man -M /usr/share/man -s 1M lpsched
Impact: 2 dependent services are not running:
        svc:/application/print/rfc1179:default
        svc:/application/print/ipp-listener:default

-a option, displays all services including the offline/disabled ones

eg.,

% svcs -a
STATE          STIME    FMRI
legacy_run     Mar_22   lrc:/etc/rcS_d/S50sk98sol
legacy_run     Mar_22   lrc:/etc/rc2_d/S20sysetup
legacy_run     Mar_22   lrc:/etc/rc2_d/S40llc2
disabled       Mar_22   svc:/network/dhcp-server:default
disabled       Mar_22   svc:/network/ipfilter:default
disabled       Mar_22   svc:/network/security/kadmin:default
online         Mar_22   svc:/system/filesystem/minimal:default
online         Mar_22   svc:/system/rmtmpfiles:default
online         Mar_22   svc:/system/keymap:default
online         Mar_22   svc:/system/name-service-cache:default
offline        Mar_22   svc:/application/print/ipp-listener:default
offline        Mar_22   svc:/application/print/rfc1179:default

-p option lists processes associated with each service instance

eg.,

% svcs -p network/telnet:default
STATE          STIME    FMRI
online         Mar_22   svc:/network/telnet:default

svcadm
___________________________

Services can be enabled/disabled with svcadm

Lets check the state of ftp server, and enable/disable it depending on its current state

% svcs -p network/ftp:default
STATE          STIME    FMRI
online         Mar_22   svc:/network/ftp:default

% ftp localhost
Connected to localhost.
220 unknown FTP server ready.
Name (localhost:techno): techno
331 Password required for techno.
Password:
^C

Since FTP server is up, let's disable the service using svcadm command

eg.,

% svcadm disable /network/ftp

% svcs -p network/ftp:default
STATE          STIME    FMRI
disabled        2:12:04 svc:/network/ftp:default

% ftp localhost
ftp: connect to address 127.0.0.1: Connection refused
Trying ::1...
ftp: connect: Network is unreachable
ftp> bye

It is very easy to enable the service again with svcadm

% svcadm enable /network/ftp

% svcs -p network/ftp:default
STATE          STIME    FMRI
online          2:14:08 svc:/network/ftp:default

At this point, though the ftp service is available, no processes are associated with the service instance. If we "ftp localhost" from another window, we can then see the ftp daemon:

% svcs -p network/ftp:default
STATE          STIME    FMRI
online          2:14:08 svc:/network/ftp:default
                2:16:27    11976 in.ftpd

pfiles
___________________________

Reports fstat() & fcntl() information for all open files in a process, including their paths

eg.,

% ps -eaf | grep xchat

    root 12022 11958   0 02:31:05 pts/4       0:00 grep xchat

isainfo
___________________________

Describes the underlying instruction set architecture

isainfo prints the name(s) of the native instruction sets for applications supported by the current version of the operating system.

With -v option, we can find out whether 64-bit applications are supported, or whether the running kernel uses 32-bit or 64-bit device drivers

eg.,

% isainfo
i386

% isainfo -v
32-bit i386 applications
        sse2 sse fxsr mmx cmov sep cx8 tsc fpu

who
___________________________

-b option, shows the time and date of the last reboot

eg.,

% who -b
   .       system boot  Mar 22 01:51

-r can be used to get the current run level of the init process

% who -r
   .       run-level 3  Mar 22 01:51     3      0  S

with -d option, who displays all processes that have expired and not been respawned by init. The exit field appears for dead processes and contains the termination and exit values of the dead process. This can be useful in determining why a process terminated.

# who -dH
NAME       LINE         TIME
techno     pts/5        Mar 25 00:58
techno     pts/7        Mar 28 00:05
techno     pts/8        Mar 27 19:19
techno     pts/6        Apr  2 02:08    (localhost)

uptime
___________________________

Shows how long the system has been up

uptime command prints the current time, the length of time the system has been up, and the average number of jobs in the run queue over the last 1, 5 and 15 minutes

eg.,

% uptime
  2:47am  up 11 day(s), 57 min(s),  1 user,  load average: 0.14, 0.15, 0.17
