Introduction
This script automatically rotates IP addresses for a cPanel account at regular intervals (e.g., every 5 or 10 minutes). It reads IPs from a file and updates the account IP sequentially.
Prerequisites
- Root SSH access
- cPanel server
- Multiple IP addresses are configured on the server
- IP list file created
Implementation
Script:
#!/bin/bash
#List of IP’s in file /root/mydomain/iplist.txt
CHANGEIP=/usr/local/cpanel/bin/setsiteip
#This is a cPanel user account
USERNAME=mail23
IPLIST=/root/mydomain/iplist_123mail.txt
CUR_IP=/root/mydomain/current_ip_123mail.txt
##REMOVE EMPTY LINES FROM FILE
sed -i “/^$/d” iplist_123mail.txt
#Current IP
CIP=$(cat ${CUR_IP})
#Total line count
TLN=$(wc -l ${IPLIST}|cut -d” ” -f1)
#Current line number
CLN=$(grep -n ${CIP} ${IPLIST}|cut -d: -f1)
echo -e “$CLN\n$TLN\n$CIP”
if [ $CLN -eq $TLN ]; then
CLN=1
echo ${CLN} > ${CUR_IP}
sed -n 1p ${IPLIST} > ${CUR_IP}
CIP=$(cat ${CUR_IP})
$CHANGEIP -u ${USERNAME} ${CIP} > ~/report_emailexp.txt
ret=$?
echo -e “CLN=1\nRET=${ret}”
else
CLN=$((CLN+1))
echo ${CLN} > ${CUR_IP}
sed -n “${CLN}”p ${IPLIST} > ${CUR_IP}
CIP=$(cat ${CUR_IP})
$CHANGEIP -u ${USERNAME} ${CIP} > ~/report_emailexp.txt
ret=$?
echo -e “CLN=${CLN}\nRET=${ret}”
fi
####SEND ALERT####
EMAIL_=rrrrrrrrrrrrttttttttttt@hotmail.com
if [ $ret -eq 0 ];then
exit 0
#msg=”IP CHANGED SUCCESSFULLY NEW IP=${CIP}”
#echo “NOTIFICATION FROM hostname”| mail -s “${msg}” ${EMAIL_}
else
msg=”IP CHANGED FAILURE IP TRIED=${CIP}”
content=$(cat ~/report.txt)
echo “$content” |mail -s “${msg}” ${EMAIL_}
fi

Conclusion
By using this script on a cPanel server, you can automatically rotate IP addresses for a specific account. Ensure all IPs are listed in /root/mydomain/iplist.txt and schedule the script via cron for periodic execution.
