Top Forums Shell Programming and Scripting Allow only particular machines to access Post 302259379 by nua7 on Tuesday 18th of November 2008 01:27:05 AM

I need to give access to port 1521 to only one machine. I found out a way by having two iptable rules.

Code:
iptables -A INPUT -s 148.147.172.226 -p tcp --dport 1521 -j ACCEPT
iptables -A INPUT -p tcp --dport 1521 -j DROP

Can anyone find any disadvantages using these rules.

Thanks!

NAME
subscription-manager-gui - Launches the UI client of the Subscription Manager. SYNOPSIS
subscription-manager-gui [--register] DESCRIPTION
subscription-manager-gui opens the local client tool to manage subscriptions and installed products on Red Hat Enterprise Linux systems. The same tasks that can be performed by invoking subscription-manager can be performed in the GUI, including registering systems with a subscription management service, applying and removing subscriptions, and viewing the subscription status of installed products. The Subscription Manager UI can also be opened by selecting the Red Hat Subscription Manager item from the Applications > System Tools menu in RHEL 5.x or the System > Administration menu in RHEL 6.x. OPTIONS
--register If a system has not yet been registered, then the GUI registration page can be opened immediately, as the Subscription Manager GUI comes up. This is only relevant for unregistered systems; if this is used after a system is registered, the option is ignored. REFERENCES
For procedures and tasks that can be performed in the Subscription Manager UI, check the Gnome help files (by pressing <F1>) or refer to the RHEL Subscription Management Guide at <https://access.redhat.com/knowledge/docs/en-US/Red_Hat_Subscription_Management/1.0/html/Sub- scription_Management_Guide/index.html>. ASSOCIATED FILES
