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 Cheers, Phil -----Original Message----- From: CentOS <centos-bounces at centos.org> On Behalf Of Erick Perez - Quadrian Enterprises Sent: 27 December 2019 03:26 To: centos at centos.org Subject: [CentOS] Disabling TLS 1.1 in Centos 7 cockpit CAUTION: This email originated from outside of the organisation. Do not click links or open attachments unless you recognise the sender and know the content is safe. 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. -- --------------------- Erick Perez --------------------- _______________________________________________ CentOS mailing list CentOS at centos.org https://lists.centos.org/mailman/listinfo/centos Hoople Ltd, Registered in England and Wales No. 7556595 Registered office: Plough Lane, Hereford, HR4 0LE "Any opinion expressed in this e-mail or any attached files are those of the individual and not necessarily those of Hoople Ltd.
