I have a textfile with the following strings with a comma in them:



John,Smith
Jane,Doe


How can I grep * using this textfile? I've tried to use grep -xFf textfile * but I don't get any results even if there are files that contain these strings.



a sample datafile within * contains this line:
1231920383939,'unix:///run/John,Smith',''



input: grep -xFf textfile *



output: (blank)






grep

    Can't reproduce here; when I create a sample text file and sample input files, grep -xFf samplefile *, I get back all the files I'm expecting. Do the data files contain one of those textfile strings on their own line? (That's what -x requires)

  • The data files contain text in this format: 1539198827392,'John,Smith','' if I use grep -xFf samplefile * I can't get that line for some reason

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
