Top Forums UNIX for Beginners Questions & Answers Cannot ftp from EXTERNAL sender Post 303042723 by jim mcnamara on Saturday 4th of January 2020 10:05:56 AM

The ftpaccess file is probably blocking the user, as a guess, something is not configured correctly in there.

Reference: Controlling FTP Server Access - System Administration Guide: Network Services

First thing to check:
Usually there is a line in the file to allow access based on network ipv4 address, example: 10.192.*
Work through all of the settings carefully one by one because there are other kinds of settings to check. ftp is a security risk, so this file exists to control access.

FWIW: We disabled ftp in favor of sftp, with Putty (free) on all of the windows desktops that needed sftp access to files.

NAME
ftphosts - FTP Server individual user host access file SYNOPSIS
/etc/ftpd/ftphosts DESCRIPTION
The ftphosts file is used to allow or deny access to accounts from specified hosts. The following access capabilities are supported: allow username addrglob [addrglob...] Only allow users to login as username from host(s) that match addrglob. deny username addrglob [addrglob...] Do not allow users to login as username from host(s) that match addrglob. A username of * matches all users. A username of anonymous or ftp specifies the anonymous user. addrglob is a regular expression that is matched against hostnames or IP addresses. addrglob may also be in the form address:netmask or address/CIDR, or be the name of a file that starts with a slash ('/') and contains additional address globs. An exclamation mark (`!') placed before the addrglob negates the test. The first allow or deny entry in the ftphosts file that matches a username and host is used. If no entry exists for a username, then access is allowed. Otherwise, a matching allow entry is required to permit access. EXAMPLES
You can use the following ftphosts file to allow anonymous access from any host except those on the class A network 10, with the exception of 10.0.0.* IP addresses, which are allowed access: allow ftp 10.0.0.* deny ftp 10.*.*.* allow ftp * 10.0.0.* can be written as 10.0.0.0:255.255.255.0 or 10.0.0.0/24.
