Don't clear your terminal history 2

Previously, on terminal use...

The door accepted your input and slid open! Unfortunately, so did a trap door under your feet. You slide down and end up in another room. The only apparent exit is a ladder leading up to a locked hatch. Across the hatch in large, friendly letters are the words Don't Panic Gab Hero. Next to the ladder, you see another terminal that reads:

> emmrme arrate
Access granted. Door opened.
> higLss geeLeg
Access granted. Door opened.
> gnninn iiinaa
Access granted. Door opened.
> suMsma uuouoo
Access granted. Door opened.
> pfreTT mfpOlA
Access granted. Door opened.
ERROR: ENTRY MISSING! CONTINUING TO NEXT ENTRY

Looks like it is waiting for your input again...

Hint 1:

On the wall across from the terminal exists the following poem:
Wonder, wonder where they are? For wondrous things, you'll travel far.
Where, oh where could they be at? Their position, you know exact.

Hint 2:

In an attempt to gather more information from the terminal, you enter the following:
> sudo help
As if in response, the wall next to you slides up, revealing the following image:

• The intro reminds me of Zork or Dungeon, one of the first text adventure games. – Benjamin Spiegel Jul 23 '16 at 4:11

I think I know the method.

Since the picture is

Statue of Zeus at Olympia

and that is

one of the ancient wonders of the world

all of which together

have locations that spell gab hero:
Giza
Alexandria
Babylon
Halicarnassus
Ephesus
Rhodes
Olympia

And I'm pretty sure the ones that have been entered already correspond to

the first six in order, except Rhodes is skipped

Finally, the passwords are six letters followed by a space, followed by six more letters.

I wanted this to have to do with longitude and latitude, since Hint 1 tells us we know the "position exact". But I can't make those numbers correspond with the letters in the title of the Wonder, in order to make a password. I think I can now, although it makes little sense.

Here's an example:

#1 is the Great Pyramid of Giza
Its longitude and latitude is 29°58′45.03″N 31°08′03.69″E
If I translate this to decimal instead, but ignore the decimal part of the seconds, and then round, the longitude and latitude are 29.9792 N and 31.1342 E
2, 9, 9, 7, 9, 2 would be wrong, but add 1 to all of them (I guess we are supposed to skip the starting letter)
(That is 3, 10, 10, 8, 10, 3)
The 3rd letter of "Great Pyramid of Giza" is e
The 10th letter is m
The 8th letter is r
So 3, 10, 10, 8, 10, 3 --> e, m, m, r, m, e
and you get emmrme (the first half of the password)
same with 3, 1, 1, 3, 4, 2 -- add 1 and you get arrate (the second half of the password)

So for the one you actually need:

Statue of Zeus at Olympia longitude/latitude is 37°38′16.3″N 21°37′48″E
Decimalized as described above is 37.6378 N, 21.63 E
Per comment from OP, we need 13 letters, so I'll pad out with zeroes
I'm going to guess it's tfotfZ atotSS

So I'm (no longer) stuck.

• I found a different set of numbers at a different site, but I'm not sure which ones to use, so I won't edit yet. – Daphne B Jul 21 '16 at 23:53
• I'm a little confused. Can you clarify how adding one to each digit in 299792 gives the string of letters? – Dan Russell Jul 22 '16 at 1:13
• Aha! I had gotten stuck after figuring out the poem.. seconding Dan's comment though, I don't understand the numbers -> letters part you did here? – user812786 Jul 22 '16 at 1:20
• Ah, gotcha @DaphneB. You're basically using the numbers as 0-indexed coordinates to select a letter from the name of the wonder. – Dan Russell Jul 22 '16 at 15:36
• ERROR: PASSWORD MUST BE 13 CHARACTERS – David Starkey Jul 25 '16 at 13:25

I'm no good at ciphers, but I figured out the second hint, if that helps anyone else get started!

This a depiction of the Statue of Zeus at Olympia:

I didn't find any credits for the image, so the image itself must be the clue..

• TinEye knows what this is a picture of. And that makes me understand "gab hero" but unfortunately it doesn't get me further on the password. – Daphne B Jul 21 '16 at 23:14
