A call is being made in a c++ program (that is being started by a shell script)



System("shutdown -r now")


On just one embedded processor I am getting 



sh: shutdown: not found


On this same processor I am able to call shutdown from the shell. It resides in /sbin/shutdown and this is in PATH.



If I change the c++ call to



System("/sbin/shutdown -r now")


it works fine. However I am trying to understand what factors would cause this to only happen on ONE processor, if everything is the same.






linux path embedded c++ yocto

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
