How to change date & time in Solaris, Linux, HP-UX and Netapp?

Changing date/time in Solaris, Linux, HP-UX and Netapp is one command step as long as used with correct syntax.

For Solaris:

# date
Thu Aug 27 00:22:37 SGT 2009
# date 0827002509
Thu Aug 27 00:25:00 SGT 2009
# date
Thu Aug 27 00:25:02 SGT 2009

For Netapp:

# ssh filer01 date
Thu Aug 27 00:20:11 SGT 2009

# ssh filer01 date 0827002509
Error: 27 is not a valid month of the year. Range is 01-12.
usage: date [-u] [[[[CC]yy]mm]dd]hhmm[.ss]]
       date [-u] -c
       date [-f] -c initialize

# ssh filer01 date 0908270026
Thu Aug 27 00:26:00 SGT 2009

# ssh filer01 date
Thu Aug 27 00:26:03 SGT 2009

How to find server hardware model?

In Linux:

# /usr/sbin/dmidecode | grep "Product Name" | head -1
                Product Name: Sun Fire V20z

In Solaris:

# /usr/sbin/prtdiag | grep "System Configuration"
System Configuration: Sun Microsystems Sun Fire V20z

In HP-UX:

# /usr/bin/model
9000/785/C3600

Xterm - tips and tricks

xterm terminal is a powerful, programmable and full with options. It is available with almost all variants of Unix OS.

The following reference is good for at least Solaris operating system.

Explanation of switches available for xterm:
======================================================================
-T "Title name" : Used for displaying title
-bg : For background color
-fg : For foreground color
-fn : For font name (it can be name as well as size also)
-e : This x-application will open in xterm window
-geometry 180x60 : To define xterm's window size and location (optional)
-display : To send the xterm's display on "Hostname" (i.e. for remote display)

How to open Xterm on local system:
======================================================================
xterm -T "This xterm is from: `whoami`@`hostname`" -bg black -fg white -fn fixed -geometry 180x60
xterm -T "This xterm is from: `whoami`@`hostname`" -bg black -fg white -fn "*-fixed-*-*-*-20-*" -geometry 180x60


How to open Xterm on remote system:
======================================================================
xterm -T "This xterm is from: `whoami`@`hostname`" -bg black -fg white -fn fixed -display 10.10.10.230:6.0
xterm -T "This xterm is from: `whoami`@`hostname`" -bg black -fg white -fn "*-fixed-*-*-*-20-*" -display 10.10.10.230:6.0
xterm -T "This xterm is from: `whoami`@`hostname`" -bg black -fg white -fn fixed -display 10.10.10.230:6.0 -e xclock

How to enable FTP in HP-UX?

Most of the time, FTP is enabled in HP-UX systems. For some reason, if it is not enabled, here is how to enable it:

1. Login to system as root
2. Look for a file called "/etc/shells"
3. If /etc/shells is not present, then create this file and put "/bin/tcsh" in this file.
4. FTP should work now. :-)

% cat /etc/shells
/bin/tcsh

How to find HP-UX system details?

Here is the coolest thing about HP-UX b11.11. With this script/utililty, we can find lots of information about the system.. like:

1. Installed softwares
2. Installed hardware
3. System parameters (kernel)
4. Disk layout
5. filesystem and volume information
6. LVM/JFS information
7. RAM/swap and other details.

The only thing is it doesn't come with all versions/releases of HP-UX. But if it is available, then it is extremely useful utility.

# /opt/ignite/bin/print_manifest

# rdate -s serverA

"rdate" sync the date/time with NTP server keeping the local timezone of the client node in mind.
