LINUX AND VMWARE STUFF

Net Backup Activity Monitor shows backup jobs are in Queued state 

Login to the backup server and check the queue status

[root@Backupmaster ~]#  bpdbjobs | grep -i Queued
4097609         Backup           Queued            TEST-P-DB-PMTNGS1       Full-Weekly      testserver1.local.com
4097588         Backup           Queued                TEST-P-FS-WIN                Full-Weekly      testserver2.local.com
4097587         Backup           Queued                TEST-P-FS-WIN                Full-Weekly      testserver3-bkp.local.com

Queued process are getting increased 

[root@Backupmaster ~]#  bpdbjobs | grep -i Queued | wc -l
136
[root@Backupmaster ~]#  bpdbjobs | grep -i Queued | wc -l
151

Cause : nbrb process has stopped, terminated  or hung state. So there is no resource allocation for new backup jobs.

Solution : In Linux Backup Master server, run the below command.

#/usr/openv/netbackup/bin/nbrb

Now queued process are changed to Active state also in  job-details, can see the backup jobs are started.

Set up password non-expiry for user in linux

NAME

       chage - change user password expiry information    

The chage command changes the number of days between password changes and the date of the last password change. This information is used by the system to determine when a user must change their password.

Below command is used to set non-expiry for testuser
   
#chage -I -1 -m 0 -M 4294967295 -E -1 testuser

[root@nsk-linux home]# chage -I -1 -m 0 -M 4294967295 -E -1 testuser1
[root@nsk-linux home]#
[root@nsk-linux home]# chage -l testuser1
Last password change                                    : Dec 10, 2017
Password expires                                        : never
Password inactive                                       : never
Account expires                                         : never
Minimum number of days between password change          : 0
Maximum number of days between password change          : 4294967295
Number of days of warning before password expires       : 7

Here
-I  Set the number of days of inactivity after a password has expired before the account is locked
-m  --mindays. Minimum number of days between password changes. A value of zero for this field indicates that the user may change their pssword at any time
-M  --maxdays. Maximum number of days during which a password is valid
-E  --expiredate. Set the date

Tree command is used to recursively check the number of files in folder.

tree - list contents of directories in a tree-like format

Tree is a recursive directory listing program that produces a depth indented listing of files. With no arguments, tree lists the files in the current directory.  When directory arguments are given, tree lists all the files and/or directories found in the given directories each in turn.  Upon completion of  listing all files/directories found, tree returns the total number of files and/or directories listed.

[root@testserver nsk]# tree -iLf 1 /home/nsk/
/home/nsk/
/home/nsk//audit.txt
/home/nsk//audit1.txt
/home/nsk//auditprod.txt
/home/nsk//auditprod1.txt
/home/nsk//dom
/home/nsk//ser.txt
/home/nsk//serv.txt
/home/nsk//serv1.txt
/home/nsk//server.txt
/home/nsk//umount
/home/nsk//umount-ser
/home/nsk//umount-ser1

0 directories, 12 files

Where:
    -i   Makes tree not print the indentation lines, useful when used in conjunction with the -f option.
    -L level Max display depth of the directory tree.

Situation:

              Openldap user is having issue while login to the server, it is asking password again and again.

Solution:

             Restart nslcd service. 

[root@testserver~]# /etc/init.d/nslcd restart

Home directory Error oddjob-mkhomedir not working

Situation:
While login as user, getting Error  oddjob-mkhomedir not working 

Solution:
1. yum install dbus oddjob oddjob-mkhomedir
2. service restart messagebus
3. service restart oddjob
4. Add the line "session required pam_oddjob_mkhomedir.so" to /etc/pam.d/sshd  file
5. Delete a users home directory (rm -rf /home/nskselvan)
6. Disable and enable the "Use LDAP Authentication" in authconfig-tui (authconfig-tui - an interface for configuring system authentication resources)
7. Log in using ssh as this user.
