geph4-vpn-helper我是搞不清楚这个到底该怎么用，目前就只看出来第一个参数是一个/etc/shells里面的壳。socks5还是没有tun device方便。
另外有没有可能通过geph4-client去实现账号注册、修改密码这一类操作？目前看来似乎必须使用GUI。
可以在cli上完成帳號的註冊（只是要借助curl那些工具還有steps有點多），但不能改密碼
# geph4-vpn-helper /bin/bash geph4-client connect --stdio-vpn --username x --password x

然后我把geph4-client的路径添加到/etc/shells里面：
$ sudo geph4-vpn-helper /bin/bash geph4-client connect --stdio-vpn --username x --password x

不知道这个到底如何解决
是不是要給個權限呢？？
已经是root了啊，还需要哪个权限？
Edit：哦nobody啊，我试试
試試ls -l `which geph4-client`
-rwxr-xr-x 1 root root /sbin/geph4-client
sudo /path/to/geph4-vpn-helper /path/to/geph4-client connect --username xxxx --password xxxx --exit-server xxxx --stdio-vpn --dns-listen 127.0.0.1:15353 --credential-cache /tmp/geph4-credentials.db
我用這個去連是沒有問題的，至於你那個為什麼出問題，我等下去裝個linux（話說你是什麼系統）測試一下，或者等晚點開發者來解決
我遲點去裝一個測試一下，或者等今晚開發者解決
干我忘记给geph-client用完整路径了，目前提示credentials的权限问题，应该能搞定了
你再試試，如果能用的話我就不裝那個系統了
試一下加個 --credential-cache /tmp/geph4-credentials.db
试了下面这个，能用
sudo geph4-vpn-helper `which geph4-client` connect --stdio-vpn --username x --password x --credential-cache /tmp/geph4-credentials.db --dns-listen 127.0.0.1:15353
回头我去编辑一下AUR

問個題外話，是不是你用的linux不用寫./xxx直接寫xxx就能用當前目錄下的xxx呀，如果是的話我覺得可能是當前目錄也有個xxx才出現權限問題的
用AUR直接装到/sbin里面了，属于$PATH
之前沒看到你這裡寫錯了，多了一個/bin/bash
