path issues

[Spacewalker2]

If the path parameter on cli is something like uftpd … Downloads and not uftpd … ~/Downloads I get a ls: Access failed: 550 No such file or directory. error message.

Sometimes I get error messages like below. But I'm not sure what it means and I'm not able to reproduce it with other paths. Besides everything in my $HOME is writable to uftpd. The only difference here is that I used a chattr +i on the files in the folder but when I cut the last element of the path I can access the folder and download the files.

7333> Initializing ...
7333> FTP root <path> writable, possible security violation!
7333> Failed initializing, exiting.

Thanks for this cool tool!

The first part of this report I cannot make heads or tails of. What do you do to get ls: Access failed ...?

The second part is an attempt at helping users not shooting themselves in the foot. I just noticed it's a little buggy ... but the intention is: If you really want to serve a folder that is writable to uftpd, then start it with uftpd -o writable PATH

[troglobit]

The latter part of your report is now fixed, it now always complains about security violation, unless -o writable.

[Spacewalker2]

Sorry for the misconceptions. The first part is that a relative path as parameter isn't working here. I guess the shell expands ~/Downloads to a full path and this works here all the time.

About the second part. Does it mean that the ftp root isn't writable except I use -o writable but sub-directories are writable every time?

[troglobit]

No worries, I just cannot reproduce the first part so anything you could assist with to help reproduce it would be greatly appreciated.

Second part: Yes. This to support an "upload/" sub-directory or similar.

I'm not sure if this helps. If I execute uftpd -l debug -n -o tftp=0,ftp=12345 ~/Pictures/eBay/ then it is working as expected.

Ah, thanks reproduced! :)

Looking into it ...

[troglobit]

There, pretty sure I fixed it! :-)

[Spacewalker2]

Thanks for the great work you have done now and before! If it isn't too much to ask then maybe you can create a new release please. It would allow me to use AUR for upgrading.

[troglobit]

Working on it! ;-)
