This question already has an answer here:



  • How can I replace a string in a file(s)?

    7 answers



I want to remove occurrence of a string from a given string. Like /hello: from a string like /yo:/sup:/hello:/yo:/hello:/yup.

And one thing for sure if string contains a colon in end then it must be removed.



There can be anything between /hello and colon (:) so I want to strip all from /hello to first colon (:).

  • Making the rules for one match different from the rules for the rest of the matches means you're no longer talking about a regular expression, which means it's rather difficult to do as a quick one-off.

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
