I cannot access a directory and I don't understand why:



The user 'exchange' is in the right group and can access on non mounted dir application1_exchange_test but not application1_exchange. The only difference is that application1_exchange is a nfs mount.

  • The issue will most probably be to do with the nfs root_squash option that is implemented by default. I would suggest that you take a look at the man pages for "exports"

  • Can you unmount that filesystem and check the output of ls -dl application1_exchange ? On some operating systems, the permissions on the underlying mount point matter.

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
