Simple Check Query

[rhyse]

Hi

I am trying to figure out the difference betwen the following 2 simple checks

net.tcp.service[https] and net.tcp.service[tcp,,443]

The first one doesnt work for one website of ours, it works for the others, this website has an "odd" cipher.

This cipher is not enabled by default in curl (on centos 7) but if you specify the cipher in a curl command (eg curl --ciphers ecdhe_rsa_aes_128_gcm_sha_256 -v https://website) the connection does work.

So does net.tcp.service[https] use the curl / nss libriaries , while the net.tcp.service[tcp,,443] command is effectively just a port check (telnet equivalent) ?

Any help appreciated

PS: I have seen post regarding issues with dual stack systems, the system im using is only IPv4 and as mentioned other sites using the test are fine

Thanks

I faced with same problem. Curl work fine when cipher specified in command line, but simple check of https service does not work. I looked via wireshark and found that connection can't be established because of handshake failure.
