I am writing a bash script and I need to filter out some hexadecimal value from a return string of a command in bash for example:



hexVal=`mmc extcsd read /dev/mmcblk1 | grep 'Max Enhanced Area Size'`


Will return the value of hexVal as:



Max Enhanced Are Size [MAX_ENH_SIZE_MULT]: 0x000bd8


Now, I want the value of hexVal to be returned as:



0x000bd8





bash hex

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
