Detect if a remote computer is Windows or Linux OS

Question

I have IP Address and Server name of a remote computer. I am able to query WMI to get the OS version if the computer is running Windows but is there a way i can query the remote computer and get the OS version if the computer is not running Windows ( Linux , Solaris )?

Answer 1

I guess Active Directory is going to give me what i need. This is what i have so far. Looks promising.

    using (PrincipalContext ctx = new PrincipalContext(ContextType.Domain))
    {
        ComputerPrincipal computer = ComputerPrincipal.FindByIdentity(ctx, "mylinuxservername");

        if (computer != null)
        {
            var unObject = computer.GetUnderlyingObject() as System.DirectoryServices.DirectoryEntry;
            if(null != unObject)
            {
                var osProperty = unObject.Properties.Cast<System.DirectoryServices.PropertyValueCollection>().Where(p => p.PropertyName == "operatingSystem");

                if(null != osProperty.FirstOrDefault())
                {
                    Console.WriteLine(osProperty.FirstOrDefault().Value);
                }
            }
        }
    }

There are many ways to detect that the remote computer is using Windows OS or Linux . Information gathering consist that part under penetration testing . Basically after scanning number of ports on the remote computer and the running services on these ports , we can decide that what OS is installed on the remote computer. There are one more way to check it , you can use SNMP Protocol for that purpose.

user@host $ snmpget -v2c -c <community string> <computer> <mib / oid >

eq.

user@host $ snmpget -v2c -c public x.x.x.x sysDescr.0 

will gives you the information related to the remote computer . By default <community string> is public .

从Windows PC知道远程PC的Windows版本是什么，可以运行Windows命令“ systeminfo / s [PCname]”，也可以使用
