Previously I was able to telnet to a server , but now I am facing timeout error 28.
I tried for traceroute it works and shows hopes .
I tried below command 



curl -v -m 5 telnet://ip:portnum


I am getting below error 



curl -v -m 5 telnet://ip:portnum
* About to connect() to ip port portnum (#0)
* Trying ip...
* Connection timed out after 5001 milliseconds
* Closing connection 0
curl: (28) Connection timed out after 5001 milliseconds


but for trace route , it started getting below output .

 2 * * *
 3 * * *

 5 * * *

I checked for 



route -n


and I am able to see right entries in route table .
Please let me know how I can troubleshoot ahead.



Thanks,

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
