从文件系统中查找路由器固件的 linux 内核版本

Question

我已经下载了文件DAP2690-firmware-v101-rc019.bin（链接），它是一些 D-Link 路由器的固件更新。

我已经使用binwalk -e DAP2690-firmware-v101-rc019.bin(Binwalk v1.2b)提取了它，现在我在文件夹中拥有了根文件系统squashfs-root。

我想仅从提取的文件（最好仅从文件夹中squashfs-root）了解该固件的 linux 内核版本。

我怎样才能做到这一点？

Answer 1

文件夹旁边squashfs-root有一个A0文件。

binwalk A0透露：
