How to disconnect a user when request system logout user doesn't work

 

When request system logout user can't clear a login session, we can still find the PID of that session and kill that process from the shell.

root@R1> show system users
2:13PM  up 5:13, 2 users, load averages: 0.00, 0.00, 0.00
USER     TTY      FROM                              LOGIN@  IDLE WHAT
root     d0       -                                9:01AM      - cli
lab      p0       w.x.y.z                          2:13PM      - -cli (cli)

root@R1> show system processes extensive | match lab
3236 lab        2   0  9540K  4924K select   0:00  0.00%  0.00% cli

root@R1> start shell user root

root@R1% ps -aux | grep lab

How to ensure current configuration was deleted

Problem or Goal:

NetScreen-204 ScreenOS 3.1.0r8

Solution:

The current saved configuration is in "ns_sys_config" file on the flash. To determine what files are used on flash:

ns204-> get file
device   filename               size cksum    location/sec op
flash    dnstb.rec                 1 00000000 bf40c000/029  0
flash    dhcpservl.txt             0 00000000 bf410000/029  0
flash    ns_sys_config          2067 00000000 bf440000/031  0

And in order to delete the current saved configuration file (ns_sys_config), use  "unset all" command on the CLI.

ns204-> unset all
Erase all system config, are you sure y/[n] ? y

After that, verify the ns_sys_config file was deleted.

ns204-> get file
device   filename               size cksum    location/sec op
flash    dnstb.rec                 1 00000000 bf40c000/029  0
flash    dhcpservl.txt             0 00000000 bf410000/029  0

Then reset the NetScreen device to load the default configuration.

ns204-> reset
Configuration modified, save? [y]/n n  <-- If enter "y", it will copy current running-config in memory to flash.
System reset, are you sure? y/[n] y
In reset ...
