1 Dear reader, in this document we will see differents command line |
|
|
|
2 software which can be used to connect to a gopher server. |
|
|
|
3 |
|
|
|
4 |
|
|
|
5 Printf + netcat |
|
|
|
6 =============== |
|
|
|
7 |
|
|
|
8 It's possible to write request "by hand" using printf to format the |
|
|
|
9 request string and then netcat to send it to the remote server. |
|
|
|
10 |
|
|
|
11 A request of the file "/tutorials/cmdline.txt" will looks like this : |
|
|
|
12 |
|
|
|
13 printf "/tutorials/cmdline.txt\r\n" | nc somedomain.com 70 |
|
|
|
14 |
|
|
|
15 You will get the server answer directly into your output. Be careful |
|
|
|
16 if you ask binary files, it will be displayed on your screen, this is |
|
|
|
17 not something a regular user want. If you want to download a binary |
|
|
|
18 file, you can redirect the output to a file using ">" or pipe it to |
|
|
|
19 another software (or using tee for both at the same time). |
|
|
|
20 |
|
|
|
21 The following example will download a music file, save it on the |
|
|
|
22 filesystem and play it with mpv while downloading. |
|
|
|
23 |
|
|
|
24 printf "/some_music.ogg\r\n" | nc somedomain.com 70 \ |
|
|
|
25 | tee saved_music.ogg | mpv - |
|
|
|
26 |
|
|
|
27 You may have seen that the data type is not part of the request |
|
|
|
28 string, this is because it is only useful for the client to decide how |
|
|
|
29 to handle the content. In the current case, the client is YOU, so if |
|
|
|
30 you ask a menu and you want to download a file which has been tagged |
|
|
|
31 with type "I" then you should use the right process to deal with an |
|
|
|
32 image file. |
|

35 Curl |
|
|
|
36 ==== |
|
|
|
37 |
|
|
|
38 It is possible to use curl to connect to a gopher server, most of its |
|
|
|
39 options are supported, like timeout or traffic shaping. You need to |
|
|
|
40 pass a full url with "gopher://" at the start to curl to tell it you |
|
|
|
41 want to request a gopher server. |
|
|
|
42 |
|
|
|
43 By default, curl will output the server result to stdout. Explanations |
|
|
|
44 can be found in the previous section about this. |
