/root/.ssh/config line 2: Bad protocol 2 host key algorithms ‘+ssh-rsa‘.

1、问题

ssh访问工蜂报错：
[root@localhost .ssh]# ssh -T git@git.code.tencent.com
/root/.ssh/config line 2: Bad protocol 2 host key algorithms ‘+ssh-rsa’.

2、查看openssh版本

[root@localhost .ssh]# ssh -V
OpenSSH_6.6.1p1, OpenSSL 1.0.1e-fips 11 Feb 2013

版本是OpenSSH_6.6

3、解决问题

修改配置文件

vi ~/.ssh/config将 HostkeyAlgorithms +ssh-rsa PubkeyAcceptedalgorithms +ssh-rsa注释掉文件内容如下：Host *
# HostkeyAlgorithms +ssh-rsa
# PubkeyAcceptedalgorithms +ssh-rsa

保存

4、重新生成密钥

cd ~/.ssh
rm -rf id_rsa
rm -rf id_rsa.pub
ssh-keygen -t rsa -C "xiaoxiao.com"
cat ~/.ssh/id_rsa.pub
cat ~/.ssh/id_rsa

5、查看是否可连接工蜂

ssh -T git@git.code.tencent.com

连接成功截图
