Replacement in iptables?

Question

linux

It is necessary to replace "AAA(random number)AAA" with "AAAA(desired number)AAA" in iptables, is it possible to implement? And if so, how? as a string, as I know, you can only drop it?

Answer 1

iptables-save > tmp.save
sed -i 's/AAA(рандомное число)AAA/AAAA(нужное число)AAA/g' tmp.save
iptables-restore < tmp.save

Bootstrap 4 has a class dropdown-menu-rightthat needs to be added to the dropdown-menu.
In your case this is not enough. You now have the following menu structure:

<nav class="navbar">
    ...
    <div class="navbar-collapse">
        <ul class="navbar ml-auto">
            <li>...</li>
        </ul>
        <div class="user-actions">
            <div class="dropdown">
                ...
            </div>
        </div>
    </div>
</nav>

And it should be:

<nav class="navbar">
    ...
    <div class="navbar-collapse">
        <ul class="navbar mr-auto">
            <li>...</li>
        </ul>
        <ul class="navbar mr-auto user-actions">
            <li class="dropdown">
                ...
            </li>
        </ul>
    </div>
</nav>

You don't have to use the UL listing, but you do need to use the .navbar-nav.

.navbar-nav for a full-height and lightweight navigation (including support for dropdowns).
