Hi, I recognized recently that while running dhcp-client, it sends out quite precisely e.g. the version of the kernel I use. I visualized it via displaying the respective line of any of the "/var/lib/dhcpcd/*.info" files: CLASSID='Linux 2.6.5-7.252-default i686' , but I'm sure that something like ethereal would also find it. So I attempted to change this, simply by setting in the file "/etc/sysconfig/network/dhcp" this string as it is shortly documented in that file: DHCLIENT_VENDOR_CLASS_ID="Linux 2.6.x i586" After that my client didn't run anymore and in fact have no idea, which kind of error I could make there. Please would you give me an advice, how to further modify that string that my client should send out this one?! I also tried the same separated by commas, use a single word there, etc. Thanks a lot, Pelibali
