如果很不顺,得大胆的查官方documentation和faq

安装个cvsnt也会被绊的跌跌撞撞.如果以前的安装都是顺利的,那么现在就会怀疑自己是不是忘记正确的操作方法了,是不是哪里搞错了,良久才到cvsnt.org的faq里面去看看才发现:
3.6. Error reading from server <whatever>: -1: Unknown error

This means that the client was able to connect to the server, but something disconnected it before authentication could take place.
...
In particular the Nod32 av exhibits this behaviour. The current workaround is to disable the 'IMON' service and reboot. Eset have been contacted about this problem. Until it is fixed it is recommended that Nod32 is not used on a machine running cvsnt.

3.7. Can't authenticate - server and client cannot agree on an authentication scheme (got '')

This is the same as the -1 error above.

我的nod32 imon监控才启动不到1周呢,因为家里没有用路由器害怕中毒才开的,没想到现在就撞大运撞上了.
