Is this segment fault raised when running `shuf`?

I have a script, where there is a line:



eval for i in "$1".."$2"; do [ ! -e "$3"/$i.* ] && echo "$i" ; done | shuf | mycommand "$3"


which means: first create a sequence of numbers, pipe them to shuf, and then pipe them to mycommand.



Most of time the script runs fine, but sometimes it gets segment fault error



/home/tim/bin/myscript: line 25: 10170 Exit 1 for i in 0001..734;
do
 [ ! -e XMJ/$i.* ] && echo "$i";
done
 10171 Done | shuf
 10172 Segmentation fault (core dumped) | mycommand XMJ


Does that mean that the segment fault is raised when running shuf?



What can we deduce from the error message and possibly correct it?



Thanks.

          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
