What is GNU ntpd? Your OpenWrt is unsupported, why dont you just make a new image in firmware selector (or install luci-app-attendedsysupgrade) and upgrade to a current version?

Just make sure you "sandwich" your text between two rows of backtick characters ` (which themselves will be invisible in the preview) looking like this in the editor:
```
Your Pasted Text as preformatted text with fixed width font
1
1111 (note with fixed-width fonts the numbers are right-aligned)
```
but looking like this in the rendered forum:

Your Pasted Text as preformatted text with fixed width font
   1
1111 (note with fixed-width fonts the numbers are right-aligned)
