This is not covered here, though we might add a separate howto for that some time later on. * Note that whoever manages to spoof this server name can deploy rogue images to your ThinClients. If this is a serious issue for you, consider using local storage media and the autoupdater instead. * It **might** be possible to already use HTTPS in this early stage when using iPXE. This is untested and requires building your own iPXE image. see http://ipxe.org/crypto for details. Alternatively, use ipxe.lkrn (from [[http://boot.ipxe.org/ipxe.lkrn]]) and pxelinux.0 in combination with scripted ipxe commands in the pxelinux.cfg. * You will also need an HTTP/HTTPS/FTP server with a dedicated IP (no name-based virtual hosts) for the squashfs image. - **Note:** set LBX2GO_NOSQUASHFS=true and use iPXE (e.g. with ipxe.lkrn + pxelinux.0) if you cannot use an IP for your host. Another option (untested) is explained [[https://blog.jacekk.info/2016/01/debian-live-webboot-dns/|here]] - * This image cannot be deployed via TFTP as it is too large - some TFTP servers refuse to serve files lager than 32MB, and some TFTP clients have problems with that as well. + * This image cannot be deployed via TFTP as it is too large - some TFTP servers (atftpd in particular) refuse to serve files lager than 32MB, and some TFTP clients have problems with that as well. * Also, even if you have a TFTP server/client combination that handles files larger than 32 MB, it will still be waaaay slower than the HTTP/FTP transfer. * Note that whoever manages to spoof this server name can deploy rogue images to your ThinClients. If this is a serious issue for you, consider using local storage media and the autoupdater instead. * It **might** be possible to use HTTPS with the ''fetch='' command. This is untested. * Once your setup fulfills all the requirements listed above, go ahead and build the image using the scripts listed in [[doc:howto:tce#configuring_the_build|Configuring the Build]] - make sure to choose ''export LBX2GO_IMAGETYPE='netboot''' (this should be the default) -- This mail was generated by DokuWiki at https://wiki.x2go.org/ _______________________________________________ x2go-commits mailing list [email protected] https://lists.x2go.org/listinfo/x2go-commits
