尝试在Ubuntu上运行Minecraft服务器。我只有终端,没有GNOME。不知何故,我失去了网络。 func reverse(_ x : Int) -> Int {
var stringConversion = String(x)
var negativeCharacter = false
var finalreversedString = String()
let signedInt = 2147483647 //Max for Int 32
let unSignedInt = -2147483647 // Min for Int 32
if stringConversion.contains("-"){
stringConversion.removeFirst()
negativeCharacter = true
}
var reversedString = String(stringConversion.reversed())
if reversedString.first == "0" {
reversedString.removeFirst()
}
if negativeCharacter {
finalreversedString = "-\(reversedString)"
} else {
finalreversedString = reversedString
}
return (x == 0 || Int(finalreversedString)! > signedInt || Int(finalreversedString)! < unSignedInt) ? 0 : Int(finalreversedString)!
}
仅显示环回。
ifconfig
所示:
/etc/udev/rules.d/70-persistent-net.rules
# PCI device 0x8086:0x1050 (e100)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*",
ATTR{address}=="00:0c:f1:85:4f:f2", ATTR{dev_id}=="0x0", ATTR{type}=="1",
KERNEL=="eth*", NAME="eth0"
所示:
/etc/network/interfaces
当我运行auto lo
iface lo inet loopback
auto eth0
iface eth0 inet dhcp
时
我明白了:
sudo ifup eth0
答案 0 :(得分:0)
您是否尝试重新启动并在内核消息中查找接口?
这些来自几年前我对CentOS的说明(我意识到你说过Ubuntu)(但70-persistent-net.rules部分让我觉得这可能会有所帮助):
