So, I often connect to my computer from outside via ssh, and normally there is no problem. But from time to time, I get 'Connection to (my host name) closed by remote host' suddenly after 10 minutes or longer without any apparent reasons.



Since I have firewall both in host network and client network, I am using another ssh server and establish ssh tunnel, and then connect to my remote host like below.



[remote] -reversed ssh tunnel- [server] -ssh tunnel- [client]



I have tried setting 'TCPKeepAlive' to 'no' and it improved the connection stability a bit, but still I get the sudden disconnect.



There is no such problem when the client is in the same network as the remote host, where I can connect to the remote directly without using ssh tunnel.



Is there any idea to make the connection more stable?



Thank you

          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
