Hiyas,

I installed the wu-ftp, and it works with anonymous users fine, but it wont accept any users with an account in the system (no matter what group they are in). Just says 'login incorrect'.
Am I forgetting something really general here?
/etc/ftpaccess is untouched, wu-ftp manuals wont say anything that help me in this.

Thanks in advance,

Do you have a /etc/shells file? The user's shell must be listed in the file and typically it looks something like:

/bin/bash
/bin/sh
/bin/tcsh
/bin/csh
/bin/ash
/bin/bsh
/bin/bash2

Yes, the file looks quite like the same. The users are using bash and it's there.

You didn't add the users to /etc/ftpusers, did you? A username in ftpusers is specifically denied.

An important part of learning any new piece of software is understanding the terminology it uses. Thankfully WordPress uses fairly simple names for everything that make it easy to start using the software.

No, I expecially checked the file, and tried with multiple users (with no groups etc..)

Are your usernames "normal" (8 chars or less and all lower case)? Also is there anything in the logs?

Do you get any additional error messages other than "login incorrect" ? It is quite likely there is a permission problem with one of the / dev files. Also, are you using "rftp" or "regular ftp" ?

RedHat uses pam for authentication. Did you install a pam-aware wu-ftpd? What is in the file "/etc/pam.d/ftp"?

There is no such file as /etc/pam.d/ftp, the usernames i've used are normal, and I'm using normal ftp.
What logs could I check for helping info?

If you are using RedHat then get the latest and greatest wu-ftpd-2.6.0-0.5.x from the RedHat Errata area: http://www.redhat.com/support/errata/index.html

The logs you could check are /var/log/secure, /var/log/xferlog and /var/log/messages.

Which Linux are you using? Does it use pam? As has been pointed out if pam is in use there has to be a /etc/pamd.ftp to find passwords.

This is for wu-ftpd-2.6.0-0.5.x.

/etc/pam.d/ftp:

#%PAM-1.0
auth       required /lib/security/pam_listfile.so item=user sense=deny file=/etc/ftpusers onerr=succeed
auth       required     /lib/security/pam_pwdb.so shadow nullok
auth       required     /lib/security/pam_shells.so
account    required     /lib/security/pam_pwdb.so
session    required     /lib/security/pam_pwdb.so

But again, if you use a distro that uses pam for authentication you must install a ftpd compiled with pam-support. Just putting this file in place probabely won't help.

Hih, I just copy/pasted that text to /etc/pam.d/ftp and it started working immediately. Thanks a bunch :)
