So you installed the wrong package named yast2-tftp-server instead of yast2-
ftp-server which would have been the right one.

Are these “virtual users”? If so does the following return the expected
values


su -
pure-pw show <user_name>
exit

This HowTo is “long in the tooth” but should still be helpful:

Doh. Apparently I need to increase the font size, I didn’t even see the t in there. Got the correct one installed now.

Have it set to only allow authenticated users, and that’s working in that I can’t login as anonymous anymore, however, I still can’t login as a real user. Using the information in the link you provided, I also created a virtual user, and can’t login as the virtual user, either.

For the virtual user, I get the following results to the pure-pw show command:

Alright, I went back to 11.3, installed pure-ftpd and yast2-ftp-server, and everything worked fine. Then I upgraded to 11.4, and now it’s broken again.

If I set the authentication option to Anonymous, then I can login as anonymous and upload/download files in the default directory, but I can’t get to other directories, which is fine for anonymous, but I’m trying to get a login setup so that I can get to other directories, 'cuz being caged in the generic ftp directory isn’t real useful to me.

If I set the authentication to Authenticated users, I can’t login at all, it tells me that the username is OK, but I always get an error when it tries to validate the password. Also, it seems to be doing something funky which may or may not be related. When I have the authentication set to allow anonymous, the Min and Max port values for passive mode are 40000 and 40500, respectively. When I change the authentication setting to allow authenticated users only, the min port value stays at 40000, but the max port value changes to 1024. If I go to the “expert settings” page in the Yast ftp manager, it’ll give me an error when it notices this, saying that the max port has to be greater than the min port. Changing the max port back to 40500 has no effect on whether I can login, and changing the min port to 1024 also has no effect on whether I can login.

Any other thoughts on how to fix this?

You have “PAMAuthentication” set to yes. This will allows FTP access to system accounts, is this what you want?
According to post #23 you have virtual users.

Are you you using PAM or virtual users?

Hiatt

#28

I don’t have any virtual users set up anymore, since the re-installation. I’d prefer to use the system accounts for FTP access instead, I just setup some virtual users in an attempt to follow that How To and see if I could get it working that way.

#29

Which system account(s) are you using?

Let’s also turn on debugging, this will involve editing the init script a little


vi /etc/init.d/pure-ftpd

Change the following line


startproc $FTPD_BIN $FTPD_ARGS

To this


startproc $FTPD_BIN -d $FTPD_ARGS

Then restart pure-ftpd


/etc/init.d/pure-ftpd restart

Then try logging in again, after the login fails please post the debug info that is in the /var/log/messages file.

Thanks,
Hiatt

#30

Hiatt, thanks for the help, I’ve got it working now. An acquaintance was back in town not too long ago and took a look at the config file, and he suggested commenting out the PAM authentication line and uncommenting the UNIX authentication line and using that, and this change allows me to login using the system accounts.

If there are any concerns with these changes to the config file, please let me know, as I’m obviously on unfamiliar ground here.

#31

Hi,
Try this:

  • Open Yast -> Software -> Software Management
  • Change the view to patterns
  • Scroll down to “Server Functions”
  • Enable “File Server” (you might want to unmark tftp on the right hand side as it is not safe)
  • Close and reopen Yast.
  • FTP Server should now appear under Network Services.

I use vsftpd and find it a much more manageable beast
