I have searched for a similar question here, but found nothing related.



In Linux, the dot (.) refers to the directory itself. The touch command creates a file, if it does not exist.



But what does touch . (dot as argument) do?



I have checked the GNU touch documentation and the LINFO information about dot, but found nothing related.



I have tried this command in my Fedora and it seems that nothing is changed.






linux shell touch

            Postfix configuration issue with fips on centos 7; mailgun relay

            Image
            Clash Royale CLAN TAG #URR8PPP up vote 0 down vote favorite I am trying to setup postfix to relay all mail generated on the local machine via SMTP to a mailgun relay. I have used the mailgun relay before with success on an ubuntu server, but I am migrating to a Centos 7 server which I will be running in FIPS mode. There error log is below, slightly sanitized. I have a small enough network that I choose to have each machine reach out to mailgun individually (this the loopback-only, 127.0.0.0/8 restrictions) and no firewall open port allowing smtp in to the machine. I assume the FIPS mode (and with it disabling of MD5) is causing problems, but I don't know how to overcome it or if it is even possible for tls_fprint to use some supported hash such as sha256 or sha512. However, the relay=none is slightly concerning since I have relayhost set, but perhaps that is because the smtp process is failing? Any help would be appreciated! postconf -n: alias_database = hash:/etc/alia
