To replace stock Vodafone Gigabox modem/router with a new device you need to make sure that your new device uses same settings as the original router. Vodafone enforces PPPoE protocol for encapsulating frames, enther the following details on your new router:
Username: vodafone@vodafone.ie
Password: broadband
The above works fine on ASUS RT-AX88U router and works fine.
For Netgear devices you might have to set VLAN to 10 on the WAN interface.
To create cron jobs in Linux:
Just remember the following syntax
.—————- minute (0 – 59)
| .————- hour (0 – 23)
| | .———- day of month (1 – 31)
| | | .——- month (1 – 12) OR jan,feb,mar,apr …
| | | | .—- day of week (0 – 6) (Sunday=0 or 7) OR sun,mon,tue,wed,thu,fri,sat
| | | | |
* * * * * user-name command to be executed
1. run crontab -e
and append your command/tasks as following
i.e.
* * * * * python /etc/script.py
2. can also edit crontact file directly
vim /etc/crontab and append your tasks
i.e.
* * * * * root touch filename
To view view cron jobs in Linux:
$ crontab -l
$ cat /etc/crontab
Using simple dd command we can copy ISO file directly USB drive
# dd if=input_file.ISO of=usb_drive_path
To speed up transfer we can increase block size
# dd bs=8192 if=input_file.ISO of=usb_drive_path
To view progress of the transfer
Method 1 (requires GNU Coreutils 8.24+ – Ubuntu 16.04+ ):
# dd bs=8192 if=input_file.ISO of=usb_drive_path status=progress
Method 2 – using pipe viewer
# dd bs=8192 if=input_file.ISO | pv | ds of=usb_drive_path status=progress
To get time estimation based on a file size
# dd bs=8192 if=input_file.ISO | pv -s 4G| ds of=usb_drive_path status=progress
TO DO
using ‘watch’
Sometimes you only want to update packages without upgrading kernel, there are two ways of doing this:
1. Temporarily
# yum update –exclude=<package_name>
# yum update –exclude=kernel*
2. To make it more permanent edit /etc/yum.conf file and append “exclude” keyword
[main]
cachedir=/var/cache/yum/$basesearch/$releasever
keepcache=0
debuglevel=2
logfile=/var/log/yum.log
exclude=kernel* redhat-release*
mount -t cifs -o username<username>,password=<password>,domain=<domain_name> //fqdn.com:/directory /<local_mount_point>
In order to view the full column output in PowerCLI we need to format table appropriately e.x.
PS C:\> Get-VM | Format-Table -AutoSize -Wrap
Format-Table
Formats the output as a table.
-AutoSize [<SwitchParameter>]
Adjusts the column size and number of columns based on the width of the data. By default, the column size and number are determined by the view.
-Wrap [<SwitchParameter>]
Displays text that exceeds the column width on the next line. By default, text that exceeds the column width is truncated.
After adding a separate disk run to verify if the space was added:
You do not have a valid subscription for this server. Please visit www.proxmox.com to get a list of available options.
While restoring database from DB2 9.7 to DB2 10.5 I encountered the following error:
PROBLEM
SQL2547N
The database was not restored because the backup image is from a previous release and requires rollforward recovery.
TAKEN ACTION:
I ran the DB2 check backup command db2ckbkp -h <backup_file_name>.001
And resulted with:
[1] Buffers processed: #################
Image Verification Complete – successful.
SOLUTION:
To resolve the problem a new OFFLINE backup is needed, power down your db instance and take a new backup.
