Fwd: switching to dnsmasq when using grml-terminalserver
by 洪朝貴 17 Nov '20

Sorry, only just now after finishing an article about grml customization did I realize that I didn't reply to the list... My customized version with dnsmasq, etc. is here: http://fs.cyut.edu.tw/gregslab/20/ (grml64-small-g20?.iso) The customization process is documented here in zh_TW: https://newtoypia.blogspot.com/2020/11/grml.html -- 顧好自己的隱私，快停止網路裸奔！請搜尋『貴哥的節慾手機』 Greg Chao-Kuei Hung 洪朝貴 PGP Key ID: 4096R/5828A7A7 Fingerprint: 67AF B5AB 5242 3E99 16D7 EAF8 A94D 2C92 5828 A7A7 ---------- Forwarded message --------- 寄件者：洪朝貴 <ckhung(a)cyut.edu.tw> Date: 2020年10月29日週四下午10:56 Subject: Re: [Grml] switching to dnsmasq when using grml-terminalserver To: gilberto dos santos alves <gsavix(a)gmail.com> Thanks to mika for the detailed response. Here is my detailed use case. I plan to install linux to two partitions of each computer in a Univ. computer classroom using only one usb flash drive containing a customized grml and a customized linux mint 20 ulyana. 1. Boot one computer into ulyana, with a grml kvm running inside but bridged to the host's network as the pxe server. 2. Start pxe service serving grml image, with the "netscript=http://..." option pointing to a pdmenu script full of admin options (details below). 3. Boot all other computers using pxe into grml and into the pdmenu script. 4. For each computer, choose from pdmenu the option to prepare the partitions, one EFI and the other LVM with all required volumes. Also install grml using extlinux into the EFI partition, with an additional (not-yet usable) ulyana entry. 5. For each computer, choose from pdmenu the option to receive, in parallel, the rather large ulyana image using udp-receiver. 6. From the pxe server use udp-sender to start broadcasting the ulyana image. 7. For each computer, choose from pdmenu the option to mount the ulyana image and copy files inside into an LVM volume, completing the ulyana installation. Some computers may go wrong after some use. A student should be able to choose to boot the computer using pxe and repair/re-initialize his own computer using options in the pdmenu (this time using wget instead of udp-receive). This may happen without requiring the teacher to pay attention while he (me) gives the lecture and while other students are using their ulyana in the classroom. This computer classroom may boot into windows in other class hours. There is already an existing DHCP service running all the time, and It is best not to disrupt this service. So my pxe server should be a proxy server, which only provides boot-related files but does not hand out IP's. Actually I have created a customized version of grml with manually installed pxelinux, dnsmasq, udpcast, pdmenu, gdisk, ntfs-3g, apache2, ... and have tested individual steps separately. So my problem is kind of solved now. Still it would be nice if grml comes with all of these pre-installed and even with some sample pdmenu script so that computer lab admins (in Taiwan's high schools and primary schools these are mainly busy computer teachers) can see that GNU/Linux and in particular grml can save a lot of work for them. Maybe even helping them distributing windows images (yuk). I would also like to take this opportunity to thank you all contributors for your great work on grml! It has saved me on several occasions since I started using it around 2017. I have it in each and every one of my bootable usb flash drive. I carry 3 of them with me all the time. They give me great peace of mind :-) -- 顧好自己的隱私，快停止網路裸奔！請搜尋『貴哥的節慾手機』 Greg Chao-Kuei Hung 洪朝貴 PGP Key ID: 4096R/5828A7A7 Fingerprint: 67AF B5AB 5242 3E99 16D7 EAF8 A94D 2C92 5828 A7A7 gilberto dos santos alves <gsavix(a)gmail.com> 於 2020年10月29日週四上午7:05寫道： > if we could see a use case explained with details, it will be more easy > for opinions. regards. > > Em qua, 28 de out de 2020 14:25, Michael Prokop <mika(a)grml.org> escreveu: > >> Hi, >> >> * 洪朝貴 [Sat Oct 24, 2020 at 04:00:59PM +0800]: >> >> > Is it possible to replace isc dhcp server with dnsmasq for use with >> > grml-terminalserver? >> > There is an existing dhcp server in my environment that I cannot touch >> > and therefore I need to set up a proxy dhcp server for >> > distributing only pxe-related files but not ip addresses like this: >> > https://www.theurbanpenguin.com/pxelinux-using-proxy-dhcp/ >> > Dnsmasq can do it but isc-dhcp-server does not seem to have this option. >> > Thanks! >> >> Well, you can of course use dnsmasq instead of isc-dhcp-server in >> your environment.

Hard drive partitions not seen
by david.renstrom＠gmail.com 10 Nov '20

10 Nov '20

Hi list, I've booted up my Dell laptop using a USB flash drive with GRML on it. However, I cannot see any block devices for the hard drive partitions. The only sdX devices I can see are sda1 and sda2, both for the bootable USB drive itself. To be clear, lsblk -a doesn't show any other sdX devices than sda. I would appreciate any tips regarding how I can make GRML see these partitions since I would like to make backups of them using gparted. Thanks, /David R.

switching to dnsmasq when using grml-terminalserver
by 洪朝貴 29 Okt '20

29 Okt '20

Dear All, Is it possible to replace isc dhcp server with dnsmasq for use with grml-terminalserver? There is an existing dhcp server in my environment that I cannot touch and therefore I need to set up a proxy dhcp server for distributing only pxe-related files but not ip addresses like this: https://www.theurbanpenguin.com/pxelinux-using-proxy-dhcp/ Dnsmasq can do it but isc-dhcp-server does not seem to have this option.

Start vom RAID?
by Paul S 12 Okt '20

12 Okt '20

Guten Tag, Auf einem Server hat mein Kollege einen RAID 1 Verbund mit Superblock 1.2 eingerichtet, Grub startet auf diesem RAID problemlos, aber beim Abrufen der grml iso aus Grub heraus tritt ein Fehler auf und ich lande in der BusyBox. Mit der swraid Option werden die RAIDs auch nicht richtig zusammengefügt, das funktioniert erst mit mdadm -A -s. Die dadurch entstandenen RAIDs haben jedoch andere Bezeichnungen als im Debian welches normalerweise auf dem Server läuft und es wird das falsche Gerät herangezogen um die grml iso zu laden. Der Debug Modus hat auch nicht geholfen, gleiches Problem und kein Mehrwert an Informationen betreffend des Problems. Gibt es einen fix dafür oder kann grml einfach nicht über ein derartiges RAID gestartet werden? mit freundlichen Grüßen Paul S

zfs
by John Covici 09 Jun '20

09 Jun '20

Any chance of getting sujpport for zfs in this release? I have been using it for years, but grml does not currently support it, so I have had to find something else, but it would sure be nice to use grml again. -- Your life is like a penny.

APFS ?
by Gregory Heytings 13 Mai '20

13 Mai '20

Hi list, As far as I can see, there is no easy way to mount APFS (default filesystem for macOS >= 10.13) with GRML. Am I wrong? If not, I would suggest to add fuse-apfs in its next releases, it uses only 2 MB. Thanks, Gregory

configuring grml
by gideon425xx＠gmail.com 12 Mai '20

12 Mai '20

I am booting grml using grub and using loop-booting. This works fine. I would, however, like to know if there are grub options I can use, to change how grml works. For example, can I change things so that persistence mode is enabled and X is run automatically? Currently I have to select those by hand. Regards Gideon
