Oops, excuse my typo
Create /etc/systemd/system/cockpit.service.d/ssl.conf containing
[Service]
Environment=G_TLS_GNUTLS_PRIORITY=NORMAL:-VERS-SSL3.0:-VERS-TLS1.0:-VERS-TLS1.1
Then
systemctl daemon-reload
systemctl restart cockpit
To verify that TLS 1.1 is disabled,
echo test | openssl s_client -connect localhost:9090 -tls1_1 2>&1 | grep -e Protocol -e Cipher
The expected result is:
New, (NONE), Cipher is (NONE)
Protocol : TLSv1.1
Cipher : 0000
Cheers,
Phil

Try creating /etc/system/system/cockpit.service.d/ssl.conf and putting this in it:
[Service]
Environment=G_TLS_GNUTLS_PRIORITY=NORMAL:-VERS-SSL3.0:-VERS-TLS1.0:-VERS-TLS1.1
Then
systemctl daemon-reload
systemctl restart cockpit

Subject: [CentOS] Disabling TLS 1.1 in Centos 7 cockpit

Hi, I'm using cockpit in standard port 9090 in a Centos 7 system.
Due to a suggestion from management, they want TLS 1.1 disabled system-wide in all Linux boxes and TLS 1.2 enabled.
I have not found proper documentation on how to disable it for cockpit (version 195.1 ships with Centos 7)
So far I have tried (https://cockpit-project.org/guide/149/https.html):
/usr/lib/systemd/system/cockpit.service
[Service]
Environment=G_TLS_GNUTLS_PRIORITY=-VERS-ALL:+VERS-TLS1.2
And I also created the file /etc/systemd/system/cockpit.service.d/ssl.conf
and added:
[Service]
Environment=G_TLS_GNUTLS_PRIORITY=-VERS-ALL:+VERS-TLS1.2
after that, I systemctl restart cockpit
But if I do
#openssl s_client -connect localhost:9090 -tls1_1 I get a proper response (a certificate), so TLS 1.1 is being accepted.
Suggestions?
Thanks.
