zlib 1.2.3错误场景:
问题原因:
1、网络原因,主机不可达; 
2、服务没有启动; 
3、防火墙拦截; 
我遇到的就是这个问题。
解决方法:
添加入站规则:
[root@localhost svn]# /sbin/iptables -I INPUT -p tcp --dport 3690 -j ACCEPT
[root@localhost svn]# /etc/init.d/iptables save
iptables:将防火墙规则保存到 /etc/sysconfig/iptables:     [确定]
[root@localhost svn]# service iptables restart
iptables:将链设置为政策 ACCEPT:filter mangle nat         [确定]
iptables:清除防火墙规则:                                 [确定]
iptables:正在卸载模块:                                   [确定]
iptables:应用防火墙规则:                                 [确定]
