can't access extra-packages list preseeding PXE install
Hello everybody, I'm trying to install Debian over PXE. I want to include extra packages in preseed conf with "d -i pkgsel/include". Extra packages are listed in /PACKAGES, and that list is generated by a debconf question included in early_command. My preseed file contains: [code]d-i preseed/early_command string tftp -g -r PACKAGES.tar TFTP_SERVER; tar -x PACKAGES.tar d -i pkgsel/include string $(for i in $(cat PACKAGES/debconf_answer.txt); do for l in $(ls PACKAGES/$i/*); do cat $l ; done ; done)[/code] But installer does not have access to /PACKAGES at the moment pkgsel/include is called (installer might use /target as root?) If I modify preseed : [code]d-i preseed/early_command string tftp -g -r PACKAGES.tar TFTP_SERVER; tar -x PACKAGES.tar ; mkdir /target ; cp -R /PACKAGES /target d -i pkgsel/include string $(for i in $(cat PACKAGES/debconf_answer.txt); do for l in $(ls PACKAGES/$i/*); do cat $l ; done ; done)[/code] it doesn't get better, because installer overwrites /PACKAGES when /target is created. I also tried to access /PACKAGES located on the server but of course it didn't work either: [code]d -i pkgsel/include string $(for i in $(cat http://APACHE-SERVER/PACKAGES/debconf_answer.txt); do for l in $(ls http://APACHE-SERVER/PACKAGES/$i/*); do cat $l ; done ; done) [/code] How can I do it? Thanks all for your help!!

Please back up a bit and tell us what exactly you're trying to do, what works and what doesn't. You seem to have attached a dhclient config file but that isn't correct for doing PXE boot. To do PXE boot you would normally add an entry to your local network's DHCP server, and run a tftp server that serves the netboot archive. So, how far in doing that did you get?

PXE install
Dear List -
After a little bit of searching the problem causing the "no boot filename found" error is the lack
of a PXE server. I tried to modify a template for a server
https://wiki.debian.org/PXEBootInstall. The modified file is attached.
Running Debian 8.4..
Whatismyip gives 67.83.96.189
The Arris modem is 192.168.1.145
This feeds into a Cisco wireless switch 192.168.1.1

Try:- /etc/dhcp/dhcpd.conf ensure authoritative; and ddns-update-style none; are un-commented (if you haven't done so already) # grep dhcp /var/log/syslog | tail -n 32 To see current leases and compare against configured number of leases (lease address range) in order to determine how many free addresses are available, consult:- /var/lib/dhcp/dhcpd.leases Also just wanted to say that the guys at our college has something called cyberoam filter, which also acts as a dhcp server, but now the dhcp server is disabled. I assume you mean the dhcp server on the cyberoam device has been disabled.. . and yes, more than one dhcp server on the LAN can cause problems. If you the cyberoam device is the LAN DNS server I'm not sure what the best solution would be (Cyberoam is non-user user-friendly, otherwise not so much). Temporarily isolate the LAN segment you are working with from the DNS server? Perhaps the administrators will add a directive for the pxe server and tftp server. From what limitations I recall of the web interface they'd need to use a serial console and edit dhcpd.conf (based on what you already have on your DNS) to add:- next-server yourTftpServer file name pxelinux.0 I'm not certain about how you'd modify dnsmasq on it. I'd also try starting an install with just two boxes, one that previously failed and one that previously succeeded - starting the previously failed one first. For starters I installed the server packages from this guide. http://www.howtoforge.com/perfect-server-debian-wheezy-apache2-bind-dovecot-ispconfig-3 And the dns and tftp configurations was done using this guide. http://www.howtoforge.com/setting-up-a-pxe-install-server-for-multiple-linux-distributions-on-debian-lenny And finally placed the tftp boot files in the directory as specified in the official debian guide. https://wiki.debian.org/PXEBootInstall#Set_up_TFTP_server The last reference looks good, and refers to the following.

Re: PXE install, without internet?
In case it's an issue with insufficient free dhcp leases, on the box with the dhcp server try:- (for isc-dhcp-server) cat /var/lib/dhcpd.leases and compare that against the number available in your settings No such file or directory. Maybe because I am using isc-dhcp-server, not dhcp3? also:- service dhcpd restart It was service isc-dhcp-service on my box, it restarted, but the other clients were not able to Then try booting the PXE clients again. Same result, unable to find the PXE server. At the DHCP server (first)? Please post:- /etc/dhcpd.conf /etc/default/dhcp3-server Right now away from my colleges, but I feel the requested files wont be available on the server since I am using isc-dhcp-server and not dhcp3. Just a thought.

No. Probably a DNS problem, alt+f4 in the affected installation to see where the error is. I've seen the problem but don't recall a specific cause - I also don't know your DNS, PXE and TFTP server setup. I generally use an IPCop Firewall and DNS, with PXE and TFTP on a separate (VirtualBox) machine, so my experience may not translate. I will be back next monday or tuesday.

Incidentally, I've now had time and tried two different netinstall

during the installation when the installer asks about any proxy, it
makes no difference whether or not I add the trailing slash:
http://192.168.0.127:3142 and
http://192.168.0.127:3142/
both work fine. In other words, I can't reproduce the original error
described in Anubhav's original question (24/01/14)
When I get on the network mirror page on the installation of client, I
try the following
http://{PXE_IP_Address}:3142
but it just won't work.
Could it just be that the OP typed this in when asked for a mirror
rather than for the proxy?

Only a few computers are able to find the PXE server Not all. Is there a limit on the number of machines that can be installed at a time using a PXE server? Yes, sort of. If they all boot simultaneously e.g. you're using WOL to start the install then you may encounter problems with DNS. Try extending timeouts or staggering the boots. TFTP doesn't handle more than about 100 simultaneous installations - the solution there is to use GPXE (which also allows greater flexibility with the location of the server) - and use http instead of tftp. For more than 1000 simultaneous installs I'd suggest GPXE with http via slamd. Thanks for all your support! I finally got the apt-cacher-ng part working. I love apt-cacher-ng (we're just good friends, 'really'). Apt-cacher and squid are also good for the same thing - but apt-cacher-ng has much lower resource requirements.

Fwd: PXE install, without internet?
[frwding to the liist, sent by mistake only to Scott] Thanks for everything. I have observed that a few packages are being downloaded from the internet. They maybe the security packages and updates released after package the iso.

It can't work as the snippet name is in the wrong format The correct snippet name is /etc/apt/apt.conf.d/NNproxy where NN is a number e.g.:- /etc/apt/apt.conf.d/90proxy Make sure you use the ip address not the server name I did the above.

Re: PXE install, without internet?
Okay, Thanks for everything guys!! But still I am not able to get this work.
So is what I am trying to do:
Case I : Without Preseed:
I boot from the PXE server. I go to the mirror selection page on the
debian installer.
I execute a shell. I create the directories
#mkdir -p /etc/apt/apt.conf.d
then using the nano editor: I write the following line.
Acquire::http { Proxy http://172.16.4.104:3142/;; };
I have also tried this syntax ( as suggested by Klaus)
Acquire::http::Proxy http://172.16.4.104:3142/;;
Still it downloads all the packages and the release files from the internet.
Yes on my server where apt-cacher-ng is installed, all packages have
been successfully imported from the iso.
I can confirm it as I have installed many packages from cacher from an
pre installed debian client. Works like a charm.
Now Case II:- With preseed:
1) I got the example pressed file from debian.org.Here is a link to
it. http://paste.debian.net/78953/
More specifically I have this as my repositories in preseed:
### Mirror settings
# If you select ftp, the mirror/country string does not need to be set.
#d-i mirror/protocol string ftp
d-i mirror/country string manual
d-i mirror/http/hostname string http.us.debian.org
d-i mirror/http/directory string /debian
d-i mirror/http/proxy http://172.16.4.104:3142
Now I have saved the above in /var/www/ and this is my entry in
/srv/tftp/pxelinux.cfg/default file
# D-I config version 2.0
include debian-installer/amd64/boot-screens/menu.cfg
default debian-installer/amd64/boot-screens/vesamenu.c32
prompt 0
timeout 0
label amd64
kernel debian-installer/amd64/linux
append vga=normal initrd=debian-installer/amd64/initrd.gz
netcfg/choose_interface=eth0 domain=WORKGROUP
debian-installer/country=IN debian-installer/language=en
auto-install/enable=false preseed/url=http://172.16.4.104/preseed.cfg
DEBCONF_DEBUG=5 -- quiet
When I boot a client from tftp, and I select the amd64 label on the
installer, many pages on the installer are skipped. Yet the packages
are downloaded from the internet.
I know I am little persistent, maybe I am missing something, but I
feel I am almost there. I apologize if you guys feel that I am doing
my research properly, or I am asking too noob questions. I just don't
know why I am doing this, this thing is not in my syllabus, I am not
supposed to do this, I am not getting paid for this, but still, I just
want to get it to work!
Please help!

The correct snippet name is /etc/apt/apt.conf.d/NNproxy
where NN is a number e.g.:-

Make sure you use the ip address not the server name
You can just preseed the creation of 90proxy, but it's kind of redundant
as you can preseed the proxy.

Re: PXE install, without internet?
set the proxy on the pxe server to localhost:3142 using
/etc/apt/apt.conf.d/90proxy or (/etc/apt/apt.conf)
I did the above and now on my PXE server I have 12 gb of packages cached.
What I want to do is when I boot the other computers via network, (ie
the boot from tftp on my PXE server) I want them to download all
packages from the apt-cacher-ng, instead of downloading from the
internet repositories.
When I get on the network mirror page on the installation of client, I
try the following
http://{PXE_IP_Address}:3142
but it just won't work.
I have also been advised to use a proxy in the preseed.cfg. However I
am not using any preseed file. My directory listing of tftp folder is
drwxrwxr-x 3 root root 4096 Dec 12 11:48 debian-installer
lrwxrwxrwx 1 root root 33 Dec 12 11:48 pxelinux.0 -

Just a question. Will this work now for both bootable USB and PXEA server
methods.

Re: Re: PXE install, without internet?
I installed apt-cacher-ng: I did the following: 1) Mounted my debian iso on /media/iso1/ 2) Tweaked my sources.list as deb file:/media/iso1/ wheezy main contrib (just in case) 3) And made changes in fstab to auto mount the iso. 4) created a symlynk to the pool folder in the iso to /var/cache/apt-cacher-ng/_import/ I did all the above on a 32 bit debian 7 box, pre configured with PXE server. Now, when I run import from apt-cacher-ng web interface I get the following errors: No index files detected. Unable to continue, cannot map files to internal locations. Apparantly I thought running apt-get update from the iso should solve problems, but apt-get update fails as I have 64bit repository and the server has 32 bit debian installed on the server.

PXE install, without internet?
Hey folks, I managed to convince my staff to switch to debian from windoze, and they agreed. So I managed to install a PXE server and successfully booted debian installer simultaneously on 20 machines using dhcp server. But they required an active internet connection to fetch packages over a mirror, and the bandwidth was very low, so at then end of the day, only one PC was able to set up. So is there a way to boot an entire 4gb dvd-iso from a server, so that I can install it on PC connected on a network??

You can create local mirror of repos.
http://www.debian.org/mirror/ftpmirror
Yes, with 20 machines to install via PXE boot, setting up a local mirror
is the best method by far.
Mirror means even packages *not* required, apt-caching allows a local
repository of only the packages that are actually required, with the
additional benefits of handling multiple releases and repostories.
Presuming that at least one box will be built before building all:-
If time and bandwidth are concerns just apt-cdrom add then install
packages on one box (gateway?) then apt-get install apt-cacher-ng,
followed by cp /var/cache/apt/archives/*.deb
/var/cache/apt-cacher-ng/_import, then go to
http://localhost:3142/acng-report.html and click on Start Import.
on that box # echo Acquire::http { Proxy http://localhost:3142;; };
/etc/apt/apt.conf.d/90proxy
Now when you install packages on that box it'll check apt-cacher-ng first.
You can add then add all the contents of the DVD/s to apt-cacher-ng:-
http://www.unix-ag.uni-kl.de/~bloch/acng/html/howtos.html#howto-importiso
In the preseed.cfg for the pxe set the repositories as normal and the
proxy as $apt-cacher:3142
If all the boxes are identical then simply copying or networkmounting
/var/cache/apt/archives/*.deb and, dpkg --set-selections might save some
time and bandwidth also.
Kind regards

Re: Re: PXE install, without internet?
Yes, it should be a perfect option, given the fact that students can later install any package from the mirror. I'll try this and the apt-cacher solution too. Only one question. Suppose I want to update my packages, then should I update my ftp mirror once a week, or should I update it from an official debian mirror? -- Regards, Anubhav Yadav Imperial College of Engineering and Research, Pune. -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of unsubscribe.

Re: Re: PXE install, without internet?
Thanks for replying Scott,appreciated your time and effort. If I do apt-cdrom add, It will look for the cd-rom right, not the iso. So I'll first need to mount the iso somewhere and tweak the sources.list to point to a file, rather than a dvd. And yes, one box is already ready with debian 7 32 bits, which is also a PXE server and I'll be now using the same server to install 64 bit version of debian on 20 PCs.

Re: PXE install, without internet?
So is there a way to boot an entire 4gb dvd-iso from a server, so that I can install it on PC connected on a network?? Thanks! If the machines are all the same hardware, you might additionally try other ways. Just ideas: 1. FAI (see http://fai-project.org) - just create a FAI-DVD and you can install every machine with it. More DVD's mean faster installation. 2. Try clonezilla, once you setup the first PC, you can create more images and install via multicasting. 3. You might also try to run rsync in combination with a livefilesystem to get access to the harddrive of the target. 4. And of course, try DRBL, which sets up a cloneserver. As I said, just ideas Have fun! Hans -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of unsubscribe. Trouble?

Only if you want it to actually work :)
I probably should have mentioned that /etc/apt/apt.conf is also an
option, and should be checked for anyway.

PXE install issues
Good day all. I am trying to install debian (woody) on a system in which the only bootable devices is a HDD, and a network boot ROM. I have got the tftpboot image booted using the PXE boot rom, and the installer runs fine until it gets to Install Kernel and Driver Modules. The only options i have for getting the kernel and drivers to the system is over the network (preferred), or USB (would have done that already if the install image had USB mass storage driver available). Any advice welcome. another (somewhat related) question. Is it possible to install debian directly onto a NFS filesystem?
