FIND FILES BETWEEN TIME FRAMES

November 13th, 2021, posted in Solaris

Example 1:
You want to find files between specific time frame and move them to different directory. You can use the -newer or -newmt option with find command.

In this below example I am creating 2 dummy files with different timestamp and moving any files found between those time frames are moved to directory /var/tmp/Archive.

touch -t 201310040000 first
touch -t 201410040000 last
# find . -newer first ! -newer last -type f -exec mv {} /var/tmp/Archive;

Example 2:
In this example, I am listing files between Oct 04 2013 and Oct 04 2014.
Sed command is for replacing dot ‘.’ with blank space before the file name.

#find . -newermt “2013-10-04 00:00:00” ! -newermt “2014-10-04 00:00:00” | sed ‘s/.///g’|xargs ls -l


If you require more information or any questions on the above commands please comment below.

1) Get the interface name

#ifconfig -a

2)You have number of ways to find the duplex of a NIC card and here are some of them,

The network interface I am using here is bge1

#cat /platform/sun4u/kernel/drv/bge.conf
name=”bge” parent=”/pci@780/pci@0/pci@1″ unit-address=”0,1″
adv_autoneg_cap=0 adv_1000fdx_cap=1 adv_1000hdx_cap=0 adv_100fdx_cap=1
adv_100hdx_cap=0 adv_10fdx_cap=0 adv_10hdx_cap=0;

or

#kstat bge:1 | grep adv
adv_cap_1000fdx 1
adv_cap_1000hdx 0
adv_cap_100fdx 1
adv_cap_100hdx 0
adv_cap_100T4 0
adv_cap_10fdx 0
adv_cap_asmpause 0
adv_cap_autoneg 0
adv_cap_pause 0

or

dmesg|grep -i bge

or

#dladm show-dev

or

ndd -get /dev/bge1 adv_100fdx_cap

ENABLE HTTPS ON ORACLE M SERIES SERVERS(XSCF)

If you have not enabled https on your M series servers, this is how you enable it.

 

Description From Oracle :
Hypertext Transfer Protocol (HTTP) over an authenticated/encrypted connection allows you to use the XSCF web browser securely. This is called the HTTPS service. Authentication is provided with a certificate authority and private keys. To use the HTTPS service, you must enable it, and provide an optional port number. The default port is 443. To enable HTTPS service, use the sethttps command”


1) Login to your xscf of the server through ssh
Assuming you have already configured network on xscf and enable ssh. If not, you can login through console/console server, configure network interface on xscf and then you can proceed with further steps.


2) Once you are in xscf, check the status of https
XSCF> showhttps
HTTPS status: disabled
 


3) Generate a self signed certificate.
XSCF> sethttps -c selfsign US California Irvine mycompany myemail@myemail.com
CA key and CA cert already exist. Do you still wish to update? [y|n] :y
Enter passphrase:
Verifying – Enter passphrase:


4) Check the HTTPS Status
XSCF> showhttps
HTTPS status: disabled
