Lenny-to-Squeeze Upgrade Plan - 2nd opinions sought!

by Mathew Newton

Hi everyone, I have decided to venture down what I hope is a well trodden path by now; upgrading my VPS from Debian Lenny to Squeeze. I have scoured the list archives and tried to make the most of http://www.debian.org/releases/squeeze/i386/release-notes/ch-upgrading.en.h… however I'm not ashamed to admit that I'm no expert in this regard and very much still learning so would appreciate a critique of my plan of action: - Ask Support kindly to perform a temporary disk snapshot - Login via Xen console - Verify no pending actions required for currently installed packages: aptitude (Then hit 'g' once in 'visual mode') - Verify that all packages are in an upgradable state: dpkg --audit - Show currently installed kernel(s): dpkg -l | grep linux-image Mine currently shows: ii linux-image-2.6-xen-686 2.6.26+17+lenny1 Linux 2.6 image on i686, oldstyle Xen suppor ii linux-image-2.6.26-1-xen-686 2.6.26-13lenny2 Linux 2.6.26 image on i686, oldstyle Xen sup ii linux-image-2.6.26-2-xen-686 2.6.26-26lenny2 Linux 2.6.26 image on i686, oldstyle Xen sup - Confirm non-usage of grub2: dpkg -l | grep grub Mine currently shows: ii grub 0.97-47lenny2 GRand Unified Bootloader (Legacy version) ii grub-common 1.96+20080724-16 GRand Unified Bootloader, version 2 (common - Updates apt sources lists from lenny to squeeze: sed -i s/lenny/squeeze/g /etc/apt/sources.list - Manually edit /etc/apt/source.list to confirm success of the above step and comment out any other repositories (non-Debian, backports etc) ? - Upgrade the kernel: (*** Am I aiming for the right one here? ***) aptitude install linux-image-2.6-686-bigmem - Update grub configuration: update-grub - Remove clocksource=jiffies from kopt directive in /boot/grub/menu.lst and confirm correct kernel will be loaded (i.e. default # matches new kernel position) - Upgrade udev (to minimise the risk of running the old udev with the new kernel): apt-get install udev - Reboot - Record a transcript of the upgrade session: script -t 2>~/upgrade-squeeze.time -a ~/upgrade-squeeze.script (This can be reviewed at a later date with scriptreplay ~/upgrade-squeeze.time ~/upgrade-squeeze.script) - Update the package list: apt-get update - Perform a minimal upgrade (i.e. upgrade those packages that don't require installation/removal of any other package(s)): apt-get upgrade - Complete the rest of the upgrade: apt-get dist-upgrade - Remove old/obsolete packages no longer required: apt-get autoremove - (Hopefully:) After the dust settles, advise Support that the snapshot of the old system can be removed Hope does that all look? Please don't hold back... Regards, Mathew

Ubuntu vs. Debian (was Re: Ubuntu release party tonight - London)

Based on about 8 years of running 1-3 low-usage personal servers on Debian and 6 months running ~150 Ubuntu server hosts professionally: Ubuntu Pros: - Hardware certification. I can buy hardware with a reasonable expectation that it'll work with a specific release without spending hours attempting to find out how well individual hardware components work. It's not a perfect scheme, but it's a start. - Vendor support. Dell, VMware and others package various useful bits of software and put them in their own repos. They don't all do a brilliant job at it (e.g. VMware's kernel modules are often several ABI versions behind the latest kernel security release) but they do it. [1] Ubuntu Cons: - Security releases. The Debian security team seem to ship patches first and the Ubuntu ones lag a bit. I don't think there's a hugely compelling reason to migrate between them. G [1] Whether or not you trust an organisation enough to add their repos to your apt sources is another matter. I tend to download the debs and stick them in a local apt repo, but this is significantly less work than packaging the software myself.

Ubuntu release party tonight - London

by Andy Smith

Hello, If you're going to the Ubuntu release party in London tonight: http://loco.ubuntu.com/events/ubuntu-uk/1283/detail/ Then do track me down and say hello. :) And no you can't yet use an official installer to put Oneiric Ocelot (11.10) on a BitFolk VPS, but I hope to have that available this weekend. With the usual warnings about not rushing into upgrades.

entropy.lon.bitfolk.com renumbered; old IP address will stop responding on Sunday 30th October 2011

by Andy Smith

Hi, entropy.lon.bitfolk.com [212.13.194.102] has been renumbered to 85.119.80.215. If you're making use of our free entropy service[1] then you may be referring to this host by IP address in your configuration[2]. Use of the entropy service is not configured by default, so if you don't know what I'm talking about then you most likely don't have anything to change. The old IP address will continue to respond until Sunday 30th October 2011, at which point we will be taking it out of service. If you're currently referring to it by IP address then you should change to the host name now. A summary of all renumberings currently in progress can be found here: https://tools.bitfolk.com/wiki/Renumbering_out_of_212.13.194.0/23 If you have any questions, please reply to the list or to support(a)bitfolk.com.

Some feedback about IP renumbering needed

by Andy Smith

Hello, We're now very close to the point when we need to begin getting you all to renumber your IP addresses. We are not there yet, but here is some more info: https://tools.bitfolk.com/wiki/Renumbering_out_of_212.13.194.0/23 Before finalising the procedure and sending out instructions I could use some feedback from you on a couple of points. These involve situations where BitFolk is contacting you by IP address. - BitFolk Backups Our backup servers are doing rsync-over-SSH by IP address. If we change the IP addresses our side then your backups stop working until you make your change. If we don't change the IP addresses our side then your backups will break when you make your change, and then you would need to contact support to get the change done. Which would be preferred? - Nagios checks Many of you have Nagios checks. These are done by IP address. If we immediately make the change on our side then alerts will start to fire for you, and will not right themselves until you complete the IP address change on your side. If we don't make the change on our side then as soon as you make your change, alerts will start to fire and then you'd have to contact support to ask for the monitoring to be fixed. I have a strong preference for us making the change as soon as you have the info to make the change your side, so that the monitoring fixes itself as you do the work. Any other ideas how to do it? - Old rsync-style zone transfers Some of you still have DNS secondary services driven by zone files that we are rsyncing from you. This is happening by IP address. This service was deprecated years ago, since everyone got enough RAM to run a proper DNS server for this purpose. I would like to finally retire this service. How much time would people like to stop relying on it and switch to running a real DNS server? - DNS slaves Those of you who have secondary DNS services will be running your own DNS server on your VPS and we'll be doing AXFR to that IP address. The DNS secondary service comes with Nagios monitoring, so as soon as we switch the IP configured on our side then monitoring as mentioned above will begin to alert. There can be multiple masters, so what we could do is set both old and new IP addresses so that zone transfers can continue to take place, but our monitoring can only have one IP address. With that in mind I think I would prefer to set both old and new IPs as masters, let monitoring alert for your TCP/53 and that will fix itself as your sort out your new IP address. Any other ideas how to do it? As far as possible in all cases above I would like to avoid the situation where we have to chase individual customers one-on-one about things that suddenly stopped working. I can imagine this might not be avoidable—particularly in the case of the backups—so if we have to do it, we have to do it.

spamd.lon.bitfolk.com renumbered; old IP address will stop responding on Tuesday 18th October 2011

by Andy Smith

Hi, spamd.lon.bitfolk.com [212.13.194.5] has been renumbered to 85.119.80.248. If you're making use of our free spamd service then you may be referring to this host by IP address in your mail server (or similar) config. The old IP address will continue to respond until Tuesday 18th October 2011, at which point we will be taking it out of service. You should start using the new IP address now. If you have any questions, please reply to the list or to support(a)bitfolk.com. Cheers, Andy -- http://bitfolk.com/ -- No-nonsense VPS hosting > The optimum programming team size is 1.

does bitfolk block smtp from t-mobile ip addresses?

by Joseph Heenan

Hi all, T-mobile are being quite insistent that the problems I have sending emails with 4 different providers to port 587 whilst on 3G are not at their end. I believe I already know the answer to this, but can someone from bitfolk please confirm that you don't block traffic from t-mobile 3G ip addresses on port 587...? (Has anyone come across this issue before? Seems like they have some weird filtering that drops the smtp connection after the STARTTLS - even happens on other port numbers) Thanks Joseph

a.authns.bitfolk.com has been renumbered

by Andy Smith

Hello, If BitFolk does not provide authoritative DNS services for one or more of your domains then you can ignore this email. One of our authoritative nameservers, a.authns.bitfolk.com, has been renumbered from 212.13.194.70 to 85.119.80.222. Normally you would only refer to this nameserver by name, so most of you will not need to make any modifications to DNS zones or registrar settings. If you have for some reason created records in your zones that point at 212.13.194.70 then it's now time to change these. Many of you are probably restricting zone transfer by IP address. Zone transfers will continue to come from 212.13.194.70 until Monday 17th October 2011, at which point we will switch to sourcing them from 85.119.80.222. Please add 85.119.80.222 to your ACLs now, without removing 212.13.194.70. If you have any questions about this, please do reply to the list or to support(a)bitfolk.com.
