试了好几次现在根本就连不上了 about kcptun HOT 20 CLOSED

我只能猜测，校园网对udp非常不友好， 你可以尝试把服务器端口换为8000/4000/53/554/443/80这几个端口试试，另外client的 -sndwnd 256就够了，mtu用默认的1350

from kcptun.

试了默认的端口29900,554,1755都用不了，近乎绝望时试了一下443豁然开朗！
忘了说了，0701版，魔都电信。。。

最好分别提供服务端、客户端的参数以及提示的信息

from kcptun.

服务端 ./server_linux_386 -l ":29912" -t "23.83.240.35:8883" --key "123" -mtu 1400 -sndwnd 2048 -rcvwnd 2048 --mode "fast2" > log 2>&1 &
客户端 start /b client_windows_amd64.exe -l ":2000" -r "23.83.240.35:29912" --key "123" -mtu 1400 -sndwnd 256 -rcvwnd 2048 --mode "fast2" > log 2>&1

看着像是udp 被封了

from kcptun.

你先把 -sndwnd -rcvwnd 都降到128， 稳定后，再慢慢往上加，极大可能是限流

from kcptun.

和你的问题一样，换成SNMP Millstone Version就好了，6月15号的新版本好像有问题。

from kcptun.

SNMP Millstone Version 在哪下载
换了机房 换了端口 还是不行 已累了

from kcptun.

点开release 最底下那个

from kcptun.

校验过md5么？ 是官方release么？

from kcptun.

嗯，review了一下，确实发现了一个问题，这个问题和-conn参数有关，15号的版本，一定有问题。

from kcptun.

对了，xtaci大大，服务器和客户端的版本必须要一致么？

from kcptun.

SNMP milestone之后的，都可以兼容， 等下提交新的release

from kcptun.

包括SNMP milestone吧？

from kcptun.

包括， 但还是建议两端都更新到最新版本。

from kcptun.

嗯，谢谢你的程序，很好用。

from kcptun.

还是依旧连上不，整了一天该干工作了 等等后面版本再说吧 很期待后面的版本好整 效果还是很好的

from kcptun.

@voq 可以试一下我刚修正的0616版本

from kcptun.

thank you all!
