Usage and functionality of new "/tool fetch" command

RouterOS General
1

I was tinkering around with the “fetch” command, and could not get it to work.

Typing this

/tool fetch address=192.168.1.13 file=webtest port=8888 mode=http path=/

does only create a zero-byte file named “webtest.txt” on the router, no error was given.

If called in a browser I verified the request will be answered by a correct output (html page or whatever, doesn’t matter in this case).

A packet sniff on the webserver gave that the fetch command issued the following HTTP request:

GET // HTTP/1.1
Host: 192.168.1.13
Connection: close

Trying this

/tool fetch address=192.168.1.13 file=webtest port=8888 mode=http path=admin/index.html

the packet sniff on the webserver gave that the fetch command issued the following HTTP request:

GET /admin/index.html HTTP/1.1
Host: 192.168.1.13
Connection: close

So it looks like the fetch command is always prepending a “/” to the path. This could prevent us from fetching content from the root directory of a webserver, if there are some security filters installed (which could be triggered by the double slash in the URL).

But the bigger problem is that there’s no content saved to the file. Anybody succeeded with that?

Best regards,

I haven’t experimented much with the http mode yet but I did manage to get ftp working.. sort of.. It would fail to login almost every other time I tried it..

I was going to try http mode earlier but as soon as I realized it didn’t support name based virtual hosts I gave up..

Hopefully they will improve the functionality of it soon..

Have been trying to get this function to work but it does not support http correctly. Seems that it will only connect to the default web site on the server at the ip address. Any feedback from MT would be appreciated as there is no proper reference manual for their product and it is expected of the user to wade through tons of forum posts to get answers from other users that also dont have access to a manual.

This has been a frustration of mine a while now it is taking me ages to get to answers and in some cases i have simply given up. Publishing a PROPER reference manual detailing EVERY command will go a long way towards making the product useful. Just adding functionallity to the product without the user being able to use it is like putting a ashtray on a motorbike.

if you are entering the domain name as the IP address that’s to be expected, the webserver needs the host header information to direct you to the right site, however if you are entering the domain name, then my guess is that it is looking up the host ip, and not passing the host header value.
