Wanted: Translator

Description

We are in desperate need of a translator who understands the languages of varoius Indian tribes. We already know how to speak to the Apache tribe via HTTP but we have some stuff missing. We offer 5$ per successfully translated language.

(That means you can send us 7 solutions to this challenge and will receive 5 points for each.)

SMTP
GOPHER
POP3
FINGER
TFTP
IRC
NNTP

Solution

We realised that there was a tftp server running since it was possible to connect with the following command.

tftp wildwildweb.fluxfingers.net

Afterwards we used the default ports and programs to connect to the other protocols:

SMTP

• connect to port 25 with telnet
• send mail to fluxfingers@rub.de

3.2.2. GOPHER

• connection: telnet wildwildweb.fluxfingers.net gopher
• send \r\n
• reconnect
• send 0\r\n

3.2.3. POP3

• USER flux
• PASS flux
• LIST
• RETR 1

3.2.4. FINGER

• connected to port 79 using telnet
• send \r\n to get user list
• reconnect
• send r00t\r\n to get details for the user r00t

3.2.5. TFTP

The port was open but TFTP does not support a list command, so we wrote a script. Guessing the name of the file is another solution.

perl -MNet::TFTP -e '$tftp = Net::TFTP->new("wildwildweb.fluxfingers.net"); $tftp->get("flag", \*STDOUT);'

connection to tftp:

tftp wildwildweb.fluxfingers.net
tftp> get flag

Here is the file, including a bonus text adventure.

3.2.6. IRC

• connected to port 6667
• listed the channels with /list
• joined channel #flagchannel
• send a private message to flagbot.

3.2.7. NNTP

• connection: telnet wildwildweb.fluxfingers.net nntp
• GROUP apache.chitchat
• NEXT
• ARTICLE

5 points per challenge makes 35 points in total.
