Description Apurbita Mukherjee 2020-11-02 09:07:57 UTC

Description of problem:

When vsftpd is configured to listen on a specific ip address (instead of any address) by using the listen_address statement in vsftpd.conf, it fails to start at boot because the network is not yet configured when the service tries to start. The problem only occurs when using the listen_address (or listen_address6) statement.

Starting the service manually with "systemctl start vsftpd" after logging in via ssh works fine, since the at this point, the network is fully configured.

The root cause is that the systemd unit file (/usr/lib/systemd/system/vsftpd.service) has "After=network.target" instead of "After=network-online.target".


Version-Release number of selected component (if applicable):
vsftpd-3.0.3-31.el8

How reproducible:
Always

Steps to Reproduce:
1. cat /usr/lib/systemd/system/vsftpd.service
[Unit]
Description=Vsftpd ftp daemon
After=network.target

[Service]
Type=forking
ExecStart=/usr/sbin/vsftpd /etc/vsftpd/vsftpd.conf

[Install]
WantedBy=multi-user.target

2. Restart vsftpd service. Due to above configuration, vsftpd service starts before network is up as explained above in description.


Actual results:
vsftpd service starts before network is up as explained above in description.


Expected results:
vsftpd service should start after the network is online.

Additional info:
Every time vsftpd starts at boot and trying to listen to only a specific address
