I'm trying to connect nagstamon 3.8 to old nagios server 3.2.2.
When i trying to connect i get error
'[SSL: UNSUPPORTED_PROTOCOL] unsupported protocol (_ssl.c:997)'
Two years above i haved the same problem. But then i find solution: Ubuntu 20.04 - how to set lower SSL security level?
Official release notes says "SSL 3, TLS 1.0, TLS 1.1, and DTLS 1.0 only work at security level 0, except when RSA key exchange without SHA1 is used"
Now editing /etc/ssl/openssl.cnf don't have result. openssl.cnf looks like that:
openssl_conf = openssl_init
[openssl_init]
providers = provider_sect
ssl_conf = ssl_sect
[provider_sect]
default = default_sect
legacy = legacy_sect
[default_sect]
activate = 1
[legacy_sect]
activate = 1
[ssl_sect]
system_default = system_default_sect
[system_default_sect]
CipherString = ALL:@SECLEVEL=0
Output from openssl ciphers -s -v -tls1 looks the same in my ubuntu 20.04 and 22.04 but in 20.04 all works fine unlike 22.04.
How do i can enable TLSv1 support for nagstamon or any other application in ubuntu 22.04?
