How will you add a virtual IP address to a server. Given the interface
qe0 and IP 10.10.1.150
# ifconfig qe0:1 10.10.1.150 up
where “qe0″ is an interface (e.g., le0) and N is a number between 1 and

with “ifconfig qe0:1 10.10.1.150 down”.
As with physical interfaces, all you need to do is make the
appropriate /etc/hostname.qe0:X file.

$ssh -T user@hostname

If you connect to a host this way, it will disable pseudo-tty allocation
and a command like w will not show your connection. Better add
`bash -i’ , as below.
$ssh -T user@hostname /bin/bash -i

With the below command the IP address of the system you connect to wont be
logged into known_hosts file, usually its in /root/.ssh/known_hosts.

$ssh -o UserknownHostsFile=/dev/null -T user@hostname /bin/bash -i

You can download it from this link – a 1.7GB single zip file.

See man system for more information:

[root@linuxbox C_Programs]# cat test.c
#include
main()
{
printf (“Files More than 10 MB !!\n”);
system(“find . -size +10000k”);
return 0;
}

[root@linuxbox C_Programs]# gcc test.c

[root@linuxbox C_Programs]# ./a.out
Files More than 10 MB !!
./xemacs-packages-extra-20061221-1.fc7.noarch.rpm

printf (“Hello Sriram!!\n”);

return 0;

}

Executing the above :
=====================
[root@linuxbox C_Programs]# gcc test.c

[root@linuxbox C_Programs]# ls
a.out test.c

[root@linuxbox C_Programs]# ./a.out
Hello Sriram!!

Finding files which are more than 10 MB:
========================================

find /tmp -name “*” -size +10000k

Finding files modified 3 days ago but less than 5 days:
========================================================

find /tmp -type f -mtime +2 -mtime -5

Find files that were accessed exactly 3 days a go
==================================================
find /tmp -type f -atime 3

-atime +7: All files that were last accessed more than 7 days ago
-atime 7: All files that were last accessed exactly 7 days ago
-atime -7: All files that were last accessed less than7 days ago

To replace recursive in *.html files, with multiline support:
=============================================================
find ./dir/ -name *.html -exec perl -pi -e ‘undef $/;
s/REPLACE-THIS/WITH-THAT/s’ {} \;

Update the modification date for all files in the
current directory and below:
=================================================
find . -exec touch {} \;

Remove files in a directory that were created more
than x number of days ago (great for managing Maildir).
======================================================
find ./ -ctime +x | xargs | rm -f -r

This should delete files older than 7 days, and
print the name of each file it deletes.
=================================================
find ./ -ctime +7 -name “*.zip” -exec rm -f {} \; -ls

# If you want to be prompted before it deletes a file:
find ./ -ctime +7 -name “*.zip” -exec rm -i {} \; -ls

This will list the files with names ending in .c
and containing the word hello:
=================================================

find . -type f -name ‘*.c’ -exec grep -l hello {} /dev/null \;

Find all the files recursively that contain foo:
================================================
find . | xargs grep foo
./a:foo
./c:foo
./d:ifoo

a,c,d are the file names that contain foo

When I tried mounting the NTFS Partition

# mount /dev/hda1 /mnt/win
mount: unknown filesystem type ‘ntfs’

I got the above message.

Then this is what I did to Mount windows NTFS partition

Install the below packages from Fedora core 7 DVD

rpm -ivh fuse-2.6.5-1.fc7.i386.rpm
rpm -ivh fuse-libs-2.6.5-1.fc7.i386.rpm
rpm -ivh ntfs-3g-1.516-1.fc7.i386.rpm

I create a directory

Ebooks Program Files

1) swinstall – installs software selections from a software source to either
the local host or to one or more target selections.

2) swremove – unconfigure and remove software products that has had software
loaded with software distributor.

3) swlist – display information about software products
The swlist command has a Graphical User Interface invoked by the swlist -i option.

4) swconfig – configure, unconfigure, or reconfigure installed software.

5) swverify – verify software products.

6) swpackage — Package a software distribution.

7) swacl – view or modify the Access Control Lists (ACLs) which protect
software products.

swjob – display and monitor job information and create and remove jobs.

The graphical user interface version of this command can be invoked with sd
or swjob -i

9) swcopy – The swcopy command copies software between depots.
Software that is copied into a depot cannot be used directly;
it is placed there only to act as a source for installation and other SD-UX operations.

10) swreg – Register/unregister depots and roots.

11) Updating Kernel in HP-UX 11i :

#cd /stand/build
#/usr/lbin/sysadm/system_prep -s system

This extracts the kernel file from currently running system.

#mk_kernel -s system

Makes new kernel in /stand/build directory called vmunix_test.
DLKM files are produced as /dlkm.vmunix.prev

At this point, the new kernel exists in the /stand/build directory.

It is recommended that you rename the existing kernel

#mv /stand/system /stand/system.prev

Now update the new kernel with :
#kmupdate /stand/build/vmunix_test

Kmupdate will automatically create backup copies of
/stand/vmunix and /stand/dlkm

as vmunix.prev and dlkm.prev under /stand

You can shutdown and boot from new kernel.
cd /; shutdown -r 0

Shuts the system so it comes with new kernel.

12) sam – starts the menu driven system Administration Manager.

Extras:
*) /stand : This contains kernel configuration and binary file that are required to
bring up a system. The important files in this dir is system, cmunix and dlkm files.

*) Default File System used in HP-UX 11i is Journal File System(JFS).
