Re: [Server-devel] Root fs on XO1
Just to clarify a comment that James made: On XO-1, the qualification of the SD card interface was done by Quanta. They seemed to think it worked fine. When I started doing extensive testing of SD cards in preparation for using them in XO-1.5, I discovered that some XO-1s did not have a reliable SD card interface.Bit error rates aren't high (maybe an error every few days when continuously exercising the card), but unacceptable from my point of view. So as James said, it might work for you, but not work so well on an arbitrary XO-1. On later XO models, I personally tested the SD interface(s) with a wide variety of SD cards to avoid repeating the same mistake.

Re: [Server-devel] School networks and electrical equipment damage
On Jun 6, 2013, at 3:58 PM, Daniel Drake wrote: Those of us familiar with setting up school networks (server + switch + APs) in some of our deployments will be familiar with the occasional loss of hardware, due to surges in the low quality electrical supply or whatever, even when the system is protected by a cheap UPS which supposedly offers some protection. This has often been the case in Nicaragua, so the group is now buying more expensive UPSes, PoE switches, and PoE access points for new schools. This means that the server and switch are connected to mains power via a UPS which hopefully protects them, and none of the APs are connected directly to the mains (instead they get Power over Ethernet) which hopefully offers some isolation from bad electrical conditions. This equipment is expensive, especially in places like Nicaragua where lots of import taxes are applied. But the hope is that the investment pays off in that the equipment doesn't get zapped. However, one week after deploying this equipment in the first school, we are left with a server that doesn't boot, 3 out of 4 access points broken with a nice burning electronics smell, and a broken switch with a lot of visible damage to the electronics. And the most surprising thing - we had not even turned on the network yet, pending some electrical work. Everything was connected up except one crucial link - the UPS was not plugged into mains power. So all of this damage happened without any of the devices having a connection to the mains. Connectivity-wise, the setup was: WAN: Phone line - ADSL modem - XS LAN: XS - Switch - 4 APs And power connections: the XS, ADSL modem and switch were connected to the UPS. The APs were connected to the switch over ethernet for both power and data. Again, since the battery was not connected to mains power, none of the devices had a power source. The connectivity engineer's best bet is that a lightening bolt landed at the school or nearby, and that this caused a power surge on the phone line. This surge passed through the ADSL modem, server, switch, and 4 APs, destroying everything in its path (except 1 AP that was connected over a longer cable than the rest). This was my most likely hypothesis as well. I believe the damage would have been less had the UPS actually been plugged in, but most probably have their input protected, not their outputs! I figured this is a story worth sharing, for any other projects considering splashing out on more expensive equipment... Also, I'm wondering if anyone has any advice/experience here. Would others expect this more expensive setup to be more resilient to bad electrical conditions than a cheaper setup - will the investment pay off? Cat5 Ethernet transformers generally provide 1.5 kV of isolation (at each end) but PoE breaks that. I believe the actual protection provided by the UPS can vary widely. They are usually required in situations like yours to protect the hard drivers, not as much for power line protection. I would use a periodically replaced surge protector before it and maybe a surge protected power strip after it. I figure that the case of a lightening bolt might be a bit extreme, but electrical storms are a nightly occurance here almost daily during the 6 month rainy season. Nothing will protect against a direct lightning strike of the wire. The more common case is a strike near the wire or the central office which can induce still induce many kV of surge on the lines. If electrical storms are common you need to take precautions. I hope all the network cabling is indoors ? If it is only partially so, consider something like: http://www.l-com.com/surge-protector-indoor-4-port-med-power-10-100-base-t-cat5-lightning-surge-protector I have seen that some UPSs (unfortunately not these ones) allow a phone line to be passed through them, supposedly offering some protection. Would such a system protect against a lightening bolt, assuming thats what happened here? Probably not. Primary protection on the phone line should be an gapped carbon block or gas tube protector at the entrance to the building between each line of the phone pair and a good ground.These protect against higher energy surges, and generally kick in at over 1 kV. I would suggest using primary protection that includes secondary protection, such as you see in: http://www.l-com.com/surge-protector-outdoor-high-power-telephone-dsl-lightning-surge-protector-screw-terminals You could also loop it through the UPS at this point for redundancy (but it MUST remain plugged in to provide protection --- it not, it makes things worse!) Then there is the protection in the modem itself, which should be able to handle the remaining surge. They are so common in telephony as to be required --- but primary protection and proper grounding is always assumed. Sorry to hear about your misfortunes, wad

Looking at your Future list at http://wiki.laptop.org/go/XS_Install_Server#Future: * Create two separate distros, one for FC and the other for XS and declare them in the kickstart file to separate the XS packages from Fedora The XS-AU is a modular set of packages on top of Fedora 11: http://dev.laptop.org.au/projects/xs-au/wiki/Install_on_an_existing_Fedora_installation * Upgrade Fedora to latest version Once we release our version 1.0 (based on Fedora 11), we can probably move to Fedora 13 with minimal effort. Fedora 14 will be trickier, as it has been upgraded to Python 2.7. * Create separate kickstart files for full install, networking/gateway only install, services only install Our installation is completely kickstart-driven, so we are most of the way there. We have other improvements in the pipeline as well. We'd be happy to work with anyone interested in getting involved.

There is spectrum overlap between channel 1 and 5, 5 and 9, and 9 and 11. Transmissions in channel 1 will interfere with those in channel 5. Not completely, thanks to the design of the 802.11 wireless layer, but enough to significantly degrade the bandwidth available if they are physically coexistant. We instead recommend working with channels 1, 6, and 11, which theoretically have no overlap with one another. Given the consumer nature of the RF filters in WiFi units, you are best using only channels 1 and 11 if using two frequencies, to avoid cross channel interference.When testing in a dense environment (a classroom), I've seen WiFi units tuned to channel 1 receive packets transmitted on channel 6.

Re: [Server-devel] XS on XO Setup as Contingency for Main Power Outage

Also, any suggestions to make this more efficient are more than welcome. How I set up an emergency use XS on an XO-1 Since I run a public XS on a big old Dell in my house, I needed a solid contingency plan should the power go out. While I have my XS on a UPS, it's small and cheap and only keeps it up about half an hour. I do have a power inverter that we hook up to a car battery, which keeps the DSL modem, and thus our internet, up for many hours so we can use our netbooks. Charging an XO shouldn't add that much more drain. So to keep my users happy and chatting while I surf the web in the dark, I set up the XS on an XO-1. This will also be useful in the summer should my A/C unit go out when it's 100 degrees and I don't want my regular equipment to overheat. I followed the instructions here to set up an 8 GB SD card: http://wiki.laptop.org/go/XS-on-XO It takes forever for the first boot, of course, while moodle initializes. I would recommend that you use a class 6 or class 10 full size SD card for this purpose. One of the Sandisk Extreme III cards, for example. The extra cost is worth it for the server. There is a huge difference in card performance, especially for small file writes, and the new larger sized (8+GB) microSD cards tend to be especially bad. Great write-up, by the way.

Re: [Server-devel] How to setup wireless mesh network for School server
School server installations using active antennas are currently non-existant. As the school server really wants to be a gateway, you will need two network interfaces on your laptop. You will need to connect one of those to a WiFi AP for the XO(s) to connect to. Theoretically, you should be able to turn your laptop's wireless interface into that WiFi AP, but the appropriate software for doing so is not part of the school server installation. I suggest disabling the WiFi on the laptop and using two USB dongles.

Re: [Server-devel] Serving 400+ students w/ a single central XS - ejabberd nightmare?
If you aren't going to place school servers in the actual schools, and insist on centralizing them, the hardware recommended by Sameer is a good idea. My argument has always been that you want local web caching and content, and that an XS shouldn't be that much more expensive than the above hardware.

The Soekris unit (say Soekris 4501 http://www.soekris.com/net4501.htm) would sit at the school location talking to the APs via a switch on one end and create a tunnel on the other end to your XS farm. The tunnel runs over a VPN from school to XS farm. Both Soekris and Routerboard have miniPCI slots that will take hardware accelerators for VPN such as this one: http://www.soekris.com/vpn1401.htm so it is possible to run VPNs on these boards. Soekris units are almost zero maintenance (no moving parts etc.) and can also double up as APs. One thing to note: the hw VPN accelerator support under Linux isn't very robust. I've used it with BSD (http://m0n0.ch/wall/) and it works well. It will do IPSec VPN tunnels. http://m0n0.ch/wall/features.php With a zero maintenance small footprint unit at the school (will run with 12 V as well) and XS units at your school server farm you can maintain the XS units locally and keep the school network running via the VPN.

Re: [Server-devel] Debian help needed
Thanks for the offers, but after more discussion with the Uruguay team, their network architecture is different enough from that on the XS (all their schools are a single DNS domain!) that the Identity Server would not work. They will be developing a simple solution that provides the functionality of the Identity Server as far as the Presence Service is concerned, and deploying it in their laptop builds. A longer term solution will require them to rethink how they find the local school server (right now, they assume that the gateway supplied by DHCP is the school server.)

On May 30, 2008, at 5:34 PM, Anna wrote: The other weird device thing involved the second NIC. The first one gets recognized as eth0 just fine. However, the second one is seen as dummy0. I put the hardware address for the second NIC in both /etc/sysconfig/olpc-scripts/ifcfg-eth1 and /etc/sysconfig/ network-scripts/ifcfg-eth1, but service network restart still brought up dummy0. As this was late Friday afternoon before a holiday weekend, the library staff was anxious to leave and needed to lock up, so I couldn't play around with it anymore and halted the system. So here's another question - any thoughts on why it wants to see the second NIC as dummy0 and how can I make it be eth1? What hw and drivers are loaded? I saved off the outputs of lsmod, lspci, dmesg, and /var/log/ messages if you're still interested, but I did get eth1 working. It wasn't being recognized according to lspci, so I popped open the case and moved it to another slot. Eth1 then initialized on boot, but dummy0 kept getting assigned 172.18.0.1. So, here's what I did: ifdown dummy0 ifconfig eth1 172.18.0.1 netmask 255.255.240.0 service dhcpd restart You've already diagnosed and fixed the problem, but here are some more details. The XS networking setup expects the gateway to be at 172.18.0.1, which is normally assigned to the second wired interface. If no second wired interface can be found (because the second NIC wasn't being seen), then a dummy0 interface is created with that IP address. Once you moved the NIC, and it was being discovered correctly, you should have been able to run `/etc/sysconfig/olpc-scripts/network-config 0` (which is run at first boot) and it should have set things up correctly. That script, however, is not well tested for this case (it expects an unconfigured system). The two test XOs were able to pull IPs from the XS after that. Like last Friday, I didn't have time to fool around with it anymore or test registration cause they were closing up the school. On my way out, I discovered there's another issue that I'm going to have to find some way to deal with. The school IT personnel is dead set on finding some way to integrate all the wireless access points and the XS/XO into their existing network. Why? I wish I knew. Anyway, they're on their own IP scheme and they're pitching a fit that the XS isn't in line with that. 172.18 stuff is all over the XS and I can't even fathom changing it. Until they are willing to take over the server installation and maintenance, they shouldn't try to change this. It isn't hardwired into the XS/XO system per se --- you CAN configure a server to work with other IP ranges inside a school with pre-existing networking services --- but it is hardwired into the XS network subsystem. I have a real problem with their mentality. First of all, the existing school infrastructure requires an outside connection, even for basic LAN functionality. As in, if the connection to the (Windows, naturally) server room downtown goes down, school staff can't even print. That happens on an appallingly frequent basis. Unless I hear specific, concrete reasons exactly why the XS/XO stuff needs to be integrated into the existing network, I'm going to assume there aren't any and try solidify specific, compelling reasons to not do that. We will back you up on that. My vision, and this is obviously not shared by the school system IT staff (all Windows guys who hate Linux, but don't get me started), is that the XS/XO LANs will be fully independent, self contained ecosystems that doesn't necessarily require outside access to function. Sure, it'd be nice for the different schools to talk to each other, but it's not vital and if it requires messing around with their existing, unreliable Windows network to get that done, I'd just as soon not have to deal with that headache. Goodness knows I have an annoying enough time setting up Samba to share files with the XP machine (not mine) on my home LAN. They hate it because it is unknown and invalidates all their MSCE certification. Sorry. Kinda venting here. No problem.

(btw we already brought up a box w/MySQL, so hopefully it will be easy to copy tables and queries over). 2 - Should we have our own table in a single DB that is shared by Moodle and all other apps or do need our own DB. I think the DB will be used for storing who posted what blog where, pending blogs and all that kid of persistent data. Tarun may have other comments on what he needs in the DB.

We have several issues with ejabberd, and in the long term are seeking a replacement instead of finding work-arounds. -Original Message- From: Martin Langhoff [mailto:[EMAIL PROTECTED] Sent: Wednesday, May 14, 2008 12:30 AM To: Berkowitz Andrew (Project Connect) Cc: Server-devel@lists.laptop.org Subject: Re: [Server-devel] Possible Jabber Problem on Server On Wed, May 14, 2008 at 5:36 AM, Berkowitz Andrew (Project Connect) [EMAIL PROTECTED] wrote: Martin had suggested that we can just wipe out the database without reinstalling the package.

Re: [Server-devel] Possible Jabber Problem on Server
I was very explicit in my instructions: 1) Remove the package. 2) Remove the database. 3) Install the package. Installing the package probably rebuilds the database. If you re-install without removing the old database, the re-install seems to re-use the old database.

[Server-devel] Build 163
Build 163 has finally been smoke tested on a few platforms and released. This should be used for any new installations. This is a bug fix release of build 160, to ensure that ejabberd collaboration works properly when the school server can't be resolved using the DNS root servers (most cases !) http://wiki.laptop.org/go/XS_Installing_Software#OLPC_XS_161 or download directly from: http://xs-dev.laptop.org/xs/OLPC_XS_163.iso Build 161 had libertas driver problems, and an improper fix to the above problem. I will push these packages (currently in the testing repo) into the stable repo sometime in the next week, probably incorporating a few more of Martin's bug fixes.. We of course eagerly await Martin's first official release! A note about Active Antennas: I was unable to test collaboration using a mesh at 1CC. Laptops could DHCP, and register, but failed to connect with the ejabberd server (eventually dropping to using salut, or link-local XMPP). This was probably due to the large number (over twenty) of other laptops in the area on the same channel, which weren't registered to this new, test server. The same server worked fine when moved to an environment with only three laptops and tested. The moral is to always keep your laptops registered with the server, to avoid problems... Time to automate this ? Cheers, wad ___ Server-devel mailing list Server-devel@lists.laptop.org http://lists.laptop.org/listinfo/server-devel

Although the short hostname, schoolserver, has stayed the same, the domain has changed from 00b000.nycboe.org to 00b001.nycboe.org and back to 00b000.nycboe.org. When I changed the domain address, I changed the H. That's unsupported at the moment. Wad might have more experience changing the FQDN... I've only recovered from that by nuking the ejabberd installation (rpm -e ejabberd; rm -r /var/lib/ejabberd/; yum install ejabberd) Jabber servers are notoriously finicky and frequently return the nodedown message if a server's hostname changes. Exactly, and we haven't yet done the legwork to make sure that this works end-to-end. We've done enough to know that changing the host/domain name is a big problem with the current presence server. The normal resolution is to export the database, convert it and import it. I tried this conversion using the Erlang conversion utility. I also reimported the original database. Some people report that just exporting and importing, without conversion, fixes the problem. This process also did not resolve the issue. I found at least one recipe which claimed to fix this problem a while back, but didn't test it. Hm. What happens if you wipe out the mnesia database and start from scratch. Fixes the problem. Also, I have another concern. The jabber database is kept in text files. This configuration is fine for small sites. But with many users, it is better to keep the database in MySQL for better performance and better reliability. If I can get mnesia to use PostgreSQL as a backend, I'll do it. There are configuration file option for ejabberd to use postgreSQL, etc. for the database. Perhaps some volunteers can play with these ? Another question: You've reported a bug where If an XO is reimaged and then needs to re-register with the server, it cannot. In this case, is it okay to export the database as text, manually delete the entry, and then import the database. For a quick fix, you can delete the entries in the SQLite db in /home/idmgr . We'll have a UI for this later. Wrong database. If that bug is due to a database, it is the ejabberd database. But if you are referring to #6919, it is harder to replicate than Giannis indicated at first. I do this all the time, when testing builds/servers, and hadn't seen it. It was easier to replicate for a while, when the presence server in the local area was misconfigured. All these ad-hoc DBs need to be under some control, and the UI will probably be handled as an extension of Moodle's user mgmt facilities. Darn right...

that's great to hear - though I have to confess that I'd like to see
the build process (and to be able to repro it). I had forgotten that
161 had a different kernel from 160 with the ViaC3 changes.
Build process for 162:
I went into the xs/testing/updates/7/i386 repo, restored the 686
versions of the
kernel, and did a createrepo
I made the changes I wanted to xs-config, pushed them back onto git.l.o,
built the package on xs-dev, copied it into xs/testing/olpc/7/i386
repo and did a createrepo.
http://dev.laptop.org/git?p=projects/xs-config;a=summary
On duplicator.l.o, I built the livecd. I rebooted duplicator on
noticing that /dev was munged,
then copied the ISO back onto xs-dev for distribution and burned it
onto a USB key for local testing.
I'm building 162 right now, which should fix this problem.
I became aware of it last night. I guess all the build 161
installs I did were AP based...
H. Perhaps at 1CC I was testing mainly with 160? I'm sure I got
161 working at some point, or perhaps I had 160 + new packages. In any
case, I think I pushed out some xs-config changes.
Umm, yes. git.l.o doesn't show any check-ins by you (and I pulled
before starting
my changes). I built release 2, copied it into the repo, not knowing
that you had
already bumped up to release 3... I'm rebuilding 163 w. release 4,
and will rebuild
with release 5 when you merge and commit your changes...
I've installed and used build 161 on at least four servers (AMD and
Intel), and they
all worked fine through various loopholes in the problems
(domain_config worked
OK if the machine hadn't DHCP'ed, if using APs the libertas driver
wasn't loaded, etc..)
QA !I already know to test on at least two wired network
configurations, now we need
to start ensuring tests in both AP and mesh mode.
(Already checked into xs-config 2.7.1r2) I had a script which
over-wrote /etc/resolv.conf after dhclient wrote it, but it was
erroneously keeping some of the DNS servers. Instead of
fixing it, in build 161 I deleted it...
I'll look into that one. Once dhclient writes its resolv.conf, we need
to write a forwarders { $dnsservers }; forwarders only; config for
BIND.
I would suggest not using forwarders only unless necessary (the
VSAT case for this in Peru was static IP assignment.) If the
upstream DNS
goes down, the school server is perfectly capable of working down
from the roots.
Debian has the resolvconf package, which does this, or we can cook
our own.
We also want to update the provided external address in the
nameserver, and
provide the update to an upstream nameserver...
I'll do some smoke testing of 162 this morning.
Cool. I'm on IRC.
cheers,
