I have a few processes that for some reason end when they shouldn't. How can I know from the process ID if it was killed automatically by the kernel or even by some other user?




python process-management

you should trace your process by Strace Commande :



strace -p <PID> -o <OUTPUT_FILE>


or 



sudo strace -p <PID> -o <OUTPUT_FILE>


in OUTPUT_FILE you will find all Informations about the execution of your Python Script and you can have some information about what causes their ends.

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
