linux - 如何使用linux Expect脚本连接到forticlient vpn

Question

我有这段代码将我的网络连接到外部 VPN，但有时此连接会丢失。我需要我的代码来检测错误并尝试再次连接。

set force_conservative 0
if {$force_conservative} {
    set send_slow {1 .1}
    proc send {ignore arg} {
            sleep .1
            exp_send -s -- $arg
    }
}
set timeout -1
spawn $env(SHELL)
match_max 100000
proc tryconnection {} {
send -- "./forticlientsslvpn_cli --server SERVER:PORT --vpnuser USER"
 expect -exact "./forticlientsslvpn_cli --server SERVER:PORT --vpnuser USER"
        send -- "\r"
        expect -exact "\r\nPassword for VPN:"
        send -- "PASSWORD\r"
        expect -exact "\r\nSTATUS::Setting up the tunnel\r\nSTATUS::Connecting...\r"
        send -- "Y\r"
        expect -exact "\r\nSSLVPN down unexpectedly with error:6\r" {
                puts "Send Ctrl+C"
                send \003
                tryconnection
        }
        expect eof
}
tryconnection

Answer 1

我会删除 -exact 选项:

expect "*SSLVPN down unexpectedly with error:6*" { ...

尝试使用 expect -d 运行，看看为什么在失去连接时模式不匹配。
