Closed Delete all ssh user in a linux vps

[Piaro]

Isang option pa, use the lock method rather than change shell method. Either way will work. Pero mas preferred ko ito.

while IFS=":" read -r users x uid x; do { [[ $uid -ge 1000 ]] && [[ $uid -lt 65534 ]]; } && usermod -L "$users"; done </etc/passwd
[/code

madadamay ba si nobody dito ?

 

[Bon-chan]

Alternatively, pwede baguhin nalang login shell into /usr/sbin/nologin para ma-disable only instead of delete.

In-adjust ko ng konti yung one-liner: a) para hindi madamay sa modification yung 'nobody' account sa Debian which is quite an important account; b) greater than or equal to 1000 yung UID.

while IFS=":" read -r users x uid x; do { [[ $uid -ge 1000 ]] && [[ $uid -lt 65534 ]]; } && chsh -s /usr/sbin/nologin "$users"; done </etc/passwd

aayuun kaya pala. hhihi

boss may script ka dyan na delete expired users mismo sa database ?

ang alam ko yung script mo auto delete yung expired users.

example.
expired users : driver

create ako new account na same username which is driver
User already registered naka lagay kahit expire na.

Try mo 'to. 3 lines yan. Copy-paste mo sa terminal one by one. May failsafe yan na ang made-delete lang yung expired accounts at hindi affected yung non-expired.

ACCOUNTS=( $(awk -F':' '$3>=1000 && $3<65534 { print $1; }' /etc/passwd) )
for i in ${ACCOUNTS[@]}; do FOR_DELETION+=( $(grep -f <(echo $i) /etc/shadow | grep -F '!' | cut -d':' -f1) ); done
for i in "${FOR_DELETION[@]}"; do echo "Deleting user: $i ..."; userdel -rf $i; done

Hindi, safe si nobody dito as per condition:

-lt 65534
