fedora28/29/32/centos ipmi 登录解决

ipmi 登录时会报:

The viewer has terminated.

Reason: The network connection has been dropped.

解决方案:

(1) centos

sed -i 's/ 3DES_EDE_CBC,//g' /usr/lib/jvm/jre/lib/security/java.security

(2) fedora 28

sed -i 's/ 3DES_EDE_CBC,//g' /etc/crypto-policies/back-ends/java.config

(3) fedora 29/32

sed -i 's/ 3DES_EDE_CBC,//g' /etc/crypto-policies/back-ends/java.config

sed -i 's/, RSA keySize < 2048//g' /etc/crypto-policies/back-ends/java.config

出现这个问题，初步发现与 fedora 28 上的 openssl cipehrs 有关:
