A bit clunky but perhaps you could find another command.
https://packages.debian.org/stretch/netmask
$ IP=172.11.0.28 $ if [ "$(netmask -n $IP/24)" == " 172.11.0.0/24" ]; then echo OK; fi OK $ IP=172.12.0.11 $ if [ "$(netmask -n $IP/24)" == " 172.11.0.0/24" ]; then echo OK; fi $
Range:
https://packages.debian.org/stretch/prips
$ IP=172.11.0.28 $ if prips 172.11.0.11 172.11.0.55 | grep $IP; then echo OK; fi 172.11.0.28 OK $ IP=172.11.0.66 $ if prips 172.11.0.11 172.11.0.55 | grep $IP; then echo OK; fi

Hi, I would like to prepare postlogin a script that allow imap connection to roundcube for all but restrict imap access for selected users.
My question is that:
Is possible in condition IF use IP addresses as range or with mask (because I've more than one web servers) ?
My script:
#!/bin/sh if [ "$IP" = "172.11.0.28" ] ; then printf "* [ALERT] Access allowed from that IP\r\n" exec "$@" fi
CHECK_USER=
PGPASSWORD="somepass" /usr/local/pg950/bin/psql -q -t -U someuser -d maildb -c "select imap_allowed from __users where name = '$USER' LIMIT 1"if [ $CHECK_USER == "f" ] ; then exit 0 fi
if [ $CHECK_USER == "t" ] ; then exec "$@" fi
