[Linux-users] Offer - desktops.
Hey all - its been such a long time since I posted here, that I had to go look up the right address. I've got a pile of older desktops to give away. They are mini-towers with i5 CPUs and ram but there are no disks inside. There are quite a lot, so don't be shy - let me know directly by email if you want some. Pickup will be in CBD sometime in the weekend, to be agreed. -- Criggie http://criggie.org.nz/ ___ Linux-users mailing list Linux-users@lists.canterbury.ac.nz http://lists.canterbury.ac.nz/mailman/listinfo/linux-users
[Linux-users] PCs etc for grabs.
I have ~6 PCs to pass on plus more items. 4 are Hewlett Packard 8100 SFF with i3 CPUs, 2 GB ram, and 320 GB drives. They all booted fine when tested. 2 are Cyclone-branded core2duo SFF, and do not start, though have HDD drives and ram etc. All drives are blanked, at least one machine has a low profile NIC in there too. --- There's a box of routers, mostly DSL. No PSUs. Condition unknown. There's a Fortigate firewall in there too. --- 3 SCSI hard drives, ultrawide 320, two are 72GB and the third is in one of those caddies. Untested. They're all in Rolleston at the moment. If you want something, I might be able to bring it in and deliver, or possibly pickup from work. Please let me know directly. -- Criggie http://criggie.org.nz/ ___ Linux-users mailing list Linux-users@lists.canterbury.ac.nz http://lists.canterbury.ac.nz/mailman/listinfo/linux-users
[Linux-users] Charities needed
So I have a problem - we have a pile of rack servers which are coming surplus soon. They're decent spec too, 256/512 GB ram and so on. They're badged thinkmate, which is a rebadge of Supermicro. Work wants to donate them, and claim that as a tax thing, so these have to go to organisations, ideally registered charities. We may have laptops and switches to go as well. It's early days in the process, but I want to avoid the Crusher because that's not very kiwi. Who has connections with a charity or similar, that could use some lightly used hardware? If so, please contact me directly. -- Criggie http://criggie.org.nz/ ___ Linux-users mailing list Linux-users@lists.canterbury.ac.nz http://lists.canterbury.ac.nz/mailman/listinfo/linux-users

If you have a tuner card then you're after some kind of Video4Linux module - v4l has been the standard interface for a long time.

Wireless ethernet uses a different radio in the device, they're unrelated. Reminds me of the "you changed the server and now my car won't start" users, which are sadly all-too-real. Things to try: * Do other wireless clients have a problem with the home wireless? Isolate if its the AP or the client. * Does your device connect to other wireless networks and still see the cellular provider ok? * Have you installed any new software recently? VOIP software that may strongly prefer wireless ethernet over cellular data? * Check with a wifi scanner for new wireless networks in your area - if the home AP is dual band (2.4 GHz and 5 GHz) then is the problem with the crowded 2.4 GHz band ? * Reboot the client - hard power off reboot. * Forget the SSID, then reboot device and reconnect. -- Criggie http://criggie.org.nz/ ___ Linux-users mailing list Linux-users@lists.canterbury.ac.nz http://lists.canterbury.ac.nz/mailman/listinfo/linux-users

There is no setup where pop3 is the correct answer, unless a component dates from 10+ years ago in which case the question becomes one of upgrades. Why have an email provider at all? Host your own mailserver and keep it in-house or at least totally under your control. A hosted VM somewhere would be awesome and if it fails you have noone to blame but yourself. I'd offer a personal VM to CLUGgers, but I still only have one IPv4 address, so that doesn't play nicely with separation, which affects reputation. If you want an IPv6 only VM, I could do something, but realistically the lack of v4 would stuff you up. How about an AWS t2.micro in Sydney AWS for $11.68 US/mo or $9.49 US/mo with reserved instances? That's 1GB ram and 100% of 1 core for 144 minutes a day. Larger sizes available but they get spendy quickly. Disk is priced at $0.12 USD/GB/month for general purpose SSD or $0.05 USD/GB/mo for magnetic storage. You get one elastic IPv4 address for free, and additional v4 IPs cost half a cent per hour, or ~$3.72 US per month. IPv6 is offered, but I've not found a price on it. On the other end you can have a X1.32xlarge with 128 cores, 1952 GB ram, two 1.9TB SSD and 25 Gbit networking for $14,118 US/mo or $8,700 if committed. This site is very useful for comparing instance sizes and costs. http://www.ec2instances.info/?region=ap-southeast-2_duration=monthly Another option is https://www.vpscity.co.nz/vps-servers offerings starting from $20NZ /mo.

My current home project is to build more VMs and replace two elderly servers. What do you use for VMs? I use at home what I use at work, which is xenserver. There are a pair of HP servers which run in hot-cold mode (for power saving reasons) I bring the other one up only for patching, and at the end of that all the VMs are running on the other host. I know there's no decent frontend system outside a windows binary, which is annoying but one of the servers had a 2008R2 licence sticker, so I virtualised that and it works okay. A lot can be done at the command line too. I've tried but disliked Xen Orchestra. In the past I used KVM on my desktop, and that worked fairly well but having separation is a good thing. It was also possible for the host to starve VMs of CPU when doing a lot of USB transfers, which was bad when one of my VMs was the home firewall ! Long term was going to redeploy one of the physical servers as a big NAS with all the freed up drives as a lower tier storage than the iscsi box. I'm not a fan of bought NAS boxes. Rolling one's own, what network fs do you use? Compatibility with certain other OSes is not required (they can be compatible themselves for a change if they want). Yeah - I have one HP server running FreeNAS and ZFS as a filesystem. It works well as backend storage for VMs, but its not a proper redundant SAN. I'm spoiled at work with some seriously-good gear. My HP has 8x 1TB drives, and I'm only using ~200 GB of it at the moment. Power draw is not small, ballparking several hundred watts continuous. Was looking at a thecus, drobo or synology NAS instead because they run far lower power. TBH I could get away perfectly well running my VMs on local storage, but migration time is much longer. So storage backend is not redundant, and I only have a single switch so no redundancy there either. If I was doing it all over again, I might look at ZFS under linux, or simply do software raid1 and use NFS or iSCSI to export the storage. Finally have just bought some Ubiquiti APs - they'll be going in this weekend. The controller software looks good. Have heard a few people rave about them, but they can't be configured without proprietory software. How does that look in practice, and what foundations does it need to run? Basically, I pay at most $00.00 for hardware that needs otherOS, and I'm iffy about being required to run wine etc for critical infrastructure. The argument "but you only need to run it once when you configure it" is ... lacking. Concur - but you don't need wine. The controller software is written in debian / ubuntu and then ported/repackaged for windows and mac. That makes me comfortable with this solution. Without the controller software they run in an autonomous mode but reconfiguring and Captive Portal auth require the controller to be running. I had a Cisco WLC for a while and it was very similar, but the hardware died. Ubiquiti's solution looks great. My main issue is many of their APs require funny POE. I have proper 802.3af switches, I don't want to use oddball injectors as well. This list's been fairly quiet lately - what are other people doing in their networks ? Played with ARM-based SBCs for small servers, but am unimpressed. They may have wifi, HDMI, lalala, but not even non-USB Ethernet or a SATA interface. Even if it's only internal I'd like timely security updates for as long as I use the hardware. So, bottom line: HW is lacking, SW is lacking...

[Linux-users] UPS recommendation - Linux Mint Desktop, workstation plus monitor
On 07/08/17 12:00, linux-users-requ...@lists.canterbury.ac.nz wrote: The less than satisfactory Dynamix 1000VA UPS that I had a Desktop box and LCD monitor connected to, has coughed its last and been scrapped. It worked to a fashion but I guess I got what I paid for. They are a bit poor, but the price reflects that. The main downside is the battery life is lucky to be 3 years, and they often get under 2 years. The best cure for that is to do a battery test monthly without failure. Meaning switch off the wall input for 10-15 seconds once a month. My APC UPSs do that themselves every fortnight after being turned back on, and they routinely give 7 years life off a set of batteries. Now, what I'm after are "real world recommendations" of what is a linux friendly device to procure as a replacement. That is, it must play nicely with the NUT suite. First option is to simply fit new batteries to your existing UPS if its not scrapped completely. It may not be great, but better than buying a new budget thing and fighting with NUT configs. a 9AH battery is $30 +GST+Freight ex chc or you can get them from Jaycar or Farnell. A Powershield Commander 880W is $460 ++ add $265 for the SNMP board. If you want to power something small and 12V for a long time, an 18W plug-pack UPS might be the answer. These have Lithium Ion batteries, not SLA, and cost around $80 ++ http://cdlnz.com/ups100/ups106/ups110/PSDCMIN12-18 Or there's a power "brick" for $120 I have no experience of this Eaton, but at $325++ it looks not too bad. Its not ethernet though. http://cdlnz.com/ups100/ups104/ups300/5S1200AU My work has a couple of these brand new unused to flog off, with an external battery pack and rack rails and bypass switching. They're looking for about half retail, so about $8k http://cdlnz.com/ups100/ups104/ups450/9PX11KIPM In the used market APC is generally good, as long as you have the right cable. There are at least 4 APC wiring standards, and the USB cable has a 10 pin RJ45 connector at the UPS end (yes) APC with an ethernet card is fantastic - polling a device via SNMP works really well. I've applied my 'Google' skills and see a range in the marketplace, I'm already swayed toward APC but have seen EATON mentioned a few times. Eaton's SNMP card worked well for me at a previous site but I have no access to that now. From memory there was a more-budget "commander" or "centurion" UPS that worked fine too. All SNMP cards use the same protocols so nothing custom, unless you want to read battery temp or fan speed or something specialised. What are people on this list using in SOHO applications, or are we now all laptops, tablets and smart-phones. You imply that SOHO is not the same as mainstream business UPS? I personally have several APC UPSs 300W backups with USB cable, runs my desktop for ~10 mins with no monitors. 650W SmartUPS with serial cable to pfsense firewall - runs APU, ONT, POE switch and ~10 POE things 1500W Smart UPS rackmount, fitted fresh batteries 2 months ago and it ran 5 servers for 25 minutes, two switches and ~5 POE things. I also have 3000W SmartUPS with NIC that work but have dead batteries. I bought some new cheap SLA batteries from Farnell but they didn't have a suitable discharge rating and the UPS simply turns off with no mains. Not good, given it needs 8x 4.5 Ah batteries so several hundred dollars to recondition. Related - if anyone wants some 99% brand-new 4.5Ah 12V batteries I can sort you out.

I do something vaguely similar - my parents have a UFB link with the same ISP as me so traffic is zero-rated. I run backuppc on a host internally, and its configured to go grab data from their synology nas by rsync, and from their windows computer by smb. Its not ipv6 because there's an ipsec tunnel in the way, and the nas isn't v6 capable anyhow. So theirs is automatically off-site, but mine's not. So periodically I do an "archive to USB" dump from BackupPC and that gives me ~600GB of tarballs to copy to an external drive. > It even runs over IPv6 :) I'd call you a geek, but that would be pot applying the absence of colour to the kettle.

[Linux-users] Dual booting Windows 10 with Linux Mint
> Looking for an idiot proof way install Linux Mint on Windows > System attached below Your options: 1* two separate computers Honestly - this is the most idiot proof. 2* set your computer to run some kind of VM environment 3* dedicate a server machine to running VMs 4* Amazon Option 1 - Two separate computers. Its pretty easy conceptually. You need two computers, good enough for what you want to do with them. You can reduce your monitor and keyboard clutter by buying a KVM switch, or just use all the monitors! I run a software tool called Synergy that works like an antiKVM, sharing my keyboard and mouse across three separate machines with five monitors total. Option 2 - VM environment In linux that'll be KVM probably, so you can use the Host OS as a regular linux box and have any number of other VMs running as clients/guest machines. If you do more work in windows, then hyper-v is included with 64 bit versions of windows 8 and windows 10 professional or ultimate. If you run a lower/lesser/home version then there's an upgrade cost. Probably other solutions exist as well. I've used both approaches successfully, with a linux host at home and a win10 host at work. Remember the guest OS has less access to the hardware, so if your purpose for windows is to run games, then make it the Host OS and run one or more linux machines as guests. Likewise, PCI or USB passthrough is a bit odd, so choose accordingly. Memory - you need enough real memory to allow all your VMs plus the Host OS to run with minimal swapping to disk - ideally none. Option 3 - Find a server-class box with plenty of memory and look at running one of the dedicated VM servers. The host OS is much reduced and probably has no more than ssh and some kind of control application. I've worked a heap with citrix xenserver, but there are others as well. Same comments about memory, and its even more of a "all your eggs in one basket" scenario. But build it with redundant drives at a minimum and you're on track. Xenserver also supports pools, so you can have multiple servers sharing the load, and VMs can move from one to another host with zero downtime. Option 4 - how deep are your pockets? Amazon will let you run an EC2 "instance" for a dollar figure per hour, with specs of your choosing. Read the full pricing at https://aws.amazon.com/ec2/pricing/ but you can have this for free each month for a year: 750 hours of EC2 running Linux, RHEL, or SLES t2.micro instance usage 750 hours of EC2 running Microsoft Windows Server t2.micro instance usage 750 hours of Elastic Load Balancing plus 15 GB data processing 30 GB of Amazon Elastic Block Storage in any combination of General Purpose (SSD) or Magnetic, plus 2 million I/Os (with Magnetic) and 1 GB of snapshot storage 15 GB of bandwidth out aggregated across all AWS services 1 GB of Regional Data Transfer After that, t2.micro costs 2 US cents/hour for linux on demand or 2.2 US cents/hour for windows. A t2.micro has 1 GB of ram, and disk costs 12 USc/month for a GB of storage on "SSD". Downsides - its not in your vicinity, Prices above are based on Sydney which is closest to us. - a t2.micro costs $180 US per year, and 30 GB of disk costs another $44. So you're looking at $250 US/year minimum to run this tiny host. - the first hit is free the free tier is to get you on board. - If you want more resources, you pay for it. Costs grow linearly, so double the ram and double the CPU cores is roughly double the price. An x1.32xlarge has 128 CPU cores, 1.9 TB ram, 2x 1.9TB SSD, and costs $25.23/hour. Thats $18k per month or $225k per year. For that, you can buy a jolly nice server and pay for power, cooling, and fat internet at home, or host it in a physical DC.

Re: [Linux-users] modem recommendations - VoIP on 2talk
> We'd ditch ADSL in a flash if there was another option. UFB by July > 2017. Apparently. The other problem with VoIP is a confusion of purpose. VoIP might save money, but that's not the main reason for moving. Instead, VoIP increases your flexibility. One of the downsides of VoIP is expecting to put your voice over the public internet and have a low latency connection all the time. We're moderately lucky in NZ, because 2talk is only 14-17 ms away (UFB) I don't care if my teenager's phone calls are a bit blah sometimes. I don't mind if telemarketeers sound worse than normal. However, if you're depending on the voice service, then sharing multiple voice calls on your main internet link is asking for a bad user experience. There are three options 1) Use a firewall/router that can prioritise traffic (I use pfsense) 2) Allocate a dedicated internet connection for your voice link. Keep it separate from the main network 2b) If you're on a UFB business connection, explore packet marking to make use of the high priority component of your service. Home UFB lacks this. 3) Talk to your ISP - see if you can buy a second vlan/pppoe link on your existing UFB. Some ISPs can do this on ADSL and VDSL if your link is an EUBA which has prioritised voice traffic. -- Criggie http://criggie.org.nz/ ___ Linux-users mailing list Linux-users@lists.canterbury.ac.nz http://lists.canterbury.ac.nz/mailman/listinfo/linux-users

[Linux-users] xargs and awkery
I'm sure this can be optimised, but how's this for some dirty hackery.
server.dc home $ `cat _fdupes-2016-03-08.txt | xargs -n 3 | awk ' { print
"rm -f " $2, $3 " ; ln " $1 , $2 " ; ln " $1, $3 } '`
Clue 1
the input file contains the output of fdupes, and listed only triples of
identical files. There were no fours or twos
A better one would have looked for a blank line in the input, and looped
through from 2 to N .
Clue 2 before
server.dc home $ ll ./dir?/abc
-rw-rw-r-- 1 root nagios 76047612 Sep 9 22:39 ./dir1/abc
-rw-rw-r-- 1 root nagios 76047612 Sep 9 22:39 ./dir2/abc
-rw-r--r-- 1 root root 76047612 Oct 28 02:52 ./dir3/abc
Clue 3 after
server.dc home $ ll ./dir?/abc
-rw-rw-r-- 3 root nagios 76047612 Sep 9 22:39 ./dir1/abc
-rw-rw-r-- 3 root nagios 76047612 Sep 9 22:39 ./dir2/abc
-rw-rw-r-- 3 root nagios 76047612 Sep 9 22:39 ./dir3/abc
I think the nifty thing was -n 3 for xargs. I was unaware it could do that.
Answer
This machine has a lot of largish files triplicated on the disk. Since I
can't convert it to a filesyystem with deduplication, this deleted 2/3 of
the files, and hard linked them back into place.
And the script merely spits out shell commands which are then executed.
So testing it is just running the command without the backticks of
execution.
So the mount in question went from 355GB in use to 170GB, or 93% to 45%
usage.

> I was once detailed to make ethernet cables. They worked, initially. >Later they failed. >There was some sadness, cause failure mode was intermittent failure. . > My suggestion is that you take Hadley's approach:: Having done cable monkey stuff for a long time, there are some flaws and some things should be clarified. Making your own cables is perfectly okay, as long as you do it right. This means using a crimping tool, not a screwdriver. It also means using the right plugs for the style of cable you use. For patch cables that means stranded cable and stranded-compatible plugs Don't ever use solid core ethernet cable for patch leads, not ever. They work for a bit but degrade over time due to movement. Solid core is fine for in-wall installations where it will not move ever, and its a little cheaper. Don't kid yourself that your "patch leads rarely change" This is a false economy. Do get a tester too - they show pair-flips and when a link is disconnected. Very handy, expecially the near and remote units so you can test a cable where the ends are not close together. Get a proper stripping tool too - these cost under $10 and save so much hassle. Expect to bugger up a bunch of plugs getting the trim lengths correct. Yes they're magic and the wires move in the plug between insertion and crimping. Check them before crimping. If doing the shortening thing then consider that some cables are wired with different colour schemes. They are compatible if you use the same colour coding on both ends. Get yourself a colour cheat card too - and reference it. Is easy to go wrong and noone likes redoing work. The cost of all the tools means its probably not financially feasinible for ones or twos, but tools are for life and I personally don't regret dropping several hundred dollars on the gear over 10 years ago. Finally - Don't overload the RJ45 connector. I understand you're not putting ethernet over this - but what happens if someone connects their computer, or worse plugs one of these leads into a switch? Definitely label them clearly, and if you can afford to look at colour-coded wall jacks and plugs. ** I have seen a "Power Over Cat5 spare pairs" bodge connected to a switch. Amazingly it kinda worked, but fried a couple weeks later. -- Criggie http://criggie.org.nz/ ___ Linux-users mailing list Linux-users@lists.canterbury.ac.nz http://lists.canterbury.ac.nz/mailman/listinfo/linux-users

The full documented legislation is at http://www.legislation.govt.nz/act/public/2007/0007/latest/DLM405134.html I start with a nicely worded email to any contact I have at the site, politely quoting the relevant sections of the act. If they ignore or blow you off then report it at http://www.dia.govt.nz/Services-Anti-Spam-Index Remember you gave them your email address, so there's some grounds for them to claim an existing working relationship. Consider adding email aiases to your domain, and throw them away if the address becomes widely known.

[Linux-users] Nickel computers
> Message: 3 > From: Pete Mundy <p...@mac.geek.nz> > The thread reminded me of this classic Dilbert: He's right too For $25 (blame inflation) you can have a HP t5740 thin client. They're a Intel dual core atom N280 CPU at 1.6 GHz with 1 GB ram and 2 GB flash disk. I've used one as a firewall, using vlans on the gigabit ethernet port. They have VGA and Display port, but I've not had both working at once outside of windows. 7 USB2 ports, and an internal SATA connector too. There's an internal PCIe slot but it would need some creative case hacking to make it accessible. I had these running Android x86 4.4 fine, as well as debian linux. They'll come either blank or with windows XP embedded or similar. There's a power supply included of course, but it probably needs a mains power cable, likely to be a cloverleaf.

Its actually quite smart, from the POV of the senders. They'll have some random-legitimate looking gmail account joining a stack of mailing lists. I'd guarantee the list member is not the same address as the spam's sender address. People who post to those mailing lists are legitimate humans, so they reply with spam directly to the sender. Is there a way with mailman to require at least one mailing list post per year? Or it might be time for a list membership validation, but that will penalise the lurkers who rarely or never post.

[Linux-users] How do you partition disks bigger than 2 terabyte?

I noticed that windows have option to convert to GBT disk but I get the impression that it makes in unbootable which defeats the purpose of me buying it. Thanks for any advice or tips you can provide Short answer - use gdisk rather than fdisk. Gotchas could involve needing a boot partition still.

Not really old or rare enough to be in a museum, although Pleasent Point Railway Museum might be interested, whereas Ferrymead is quite space-constrained.

Re: [Linux-users] email server; of sorts
On 14/08/15 15:28, linux-users-requ...@lists.canterbury.ac.nz wrote: Indeed none of the email servers I have accounts on are under my control. All you said is do-able (including the TLS) until the sending part. Yes, I wasn't too clear on the sending part. This server software or setup I'm looking for, when replying to a message it should use the original email account on the original server where the original message was collected from to send the reply. Also when sending a new email I should be able to chose from the email client an identity that this server/setup will translate in a combination of server/account to send the emails as, and this server/setup should use that account on that server to send the message using the appropriate credentials, and keep a copy of the sent message locally. Can you do that with postfix? I mean using multiple relay servers? If yes, can you give me any pointers please where to start reading? I'm in agreement with pretty much everything already said. Fetchmail, an MTA, something to sort like procmail or sieve, an imap server, and a web frontend that talks to imap are all parts of your solution. rsync is probably not a component in this solution - getting email to multiple devices will be handled by imap. Your main problem will be sending from those other accounts. Does anyone need that expanded? It may be possible for some accounts, but probably not all. The answer is to make use of the domain you already own, and send all outbound email from there. Since you own it, you'll never be beholden to an ISP or a company ever again. If that domain name is a work one, I suggest you buy a second domain name for personal usage. -- Criggie http://criggie.org.nz/ ___ Linux-users mailing list Linux-users@lists.canterbury.ac.nz http://lists.canterbury.ac.nz/mailman/listinfo/linux-users
[Linux-users] Freenas zfs mirror or raidz 2
On 15/08/15 12:00, Bevan said I know this is not exactly a Linux question but i have just built a freenas server with 8 gigs of ram and 2 x 3TB NAS HDDs however i have also filled it and need to look at buying two more drives should i keep it mirror and snapshots or should i use raidz 2 How is it set up now? I assume its a RAID1 cos ZFS requires three (?) disks If you add drives to a RAID1 you just get spares, not more space. So you'll create a second RAID1 and have a second mountpoint. If you want to go ZFS then you'll need a temporary location to store any existing files, while you recreate the storage. What do you use it for? Important files vs large misc files vs some backend storage for a VM server ? Also, you may need more memory for ZFS - again I recall the rule of thumb is recommended 1GB ram per 1TB disk. -- Criggie http://criggie.org.nz/ ___ Linux-users mailing list Linux-users@lists.canterbury.ac.nz http://lists.canterbury.ac.nz/mailman/listinfo/linux-users
[Linux-users] media transfer to android tablet
On 04/08/15 20:41, linux-users-requ...@lists.canterbury.ac.nz wrote: Hi, I am looking for list wisdom / experience with software that plays nice between a recent Ubuntu and Android tablets / phones, for the transfer of photos, music, movies over wifi. The more user friendly the better as this is primarily for family members who are not technical. I've had a look at AirDroid which partly fits the bill, the non-friendly aspect to that is the need to navigate the android file system - I can work it out but others are going to have little chance. Are there some better options anyone knows of? Roger - At some point the users have to get comfortable with some basic concepts like files If they're not at that point or simply can't be bothered learning then you're on a hiding to nowhere and should stop wasting your time. However if they're okay with the idea of I put a file here in this folder/directory and after a bit it turns up there on my tablet then perhaps an internet-based syncing tool is your answer. I'm not a fan of cloud but in this case it might do the business. ObSecurity comment - spideroak is the only cloud synch thing that disavows all knowledge of your keys/passwords/encryption strings/etc. You'll need to get a client on your desktop and your tablet, and they'll do the magic synchy thing in the background. If you want to use droppants^Wdropbox or mega or whatever then there's probably a client there, but they do not claim to be unable to access your data. Note this doesn't sync from the tablet into the cloud - the app doesn't seem to support that, making it useless for backing up photos from the device (my plan originally) Signup link is https://spideroak.com/download/referral/d53cff10ab728227abb49caf5589da5c Or just sign up from their website... 1 GB of storage for free, up to 10 GB total by referrals, or you can buy more storage. -- Criggie http://criggie.org.nz/ ___ Linux-users mailing list Linux-users@lists.canterbury.ac.nz http://lists.canterbury.ac.nz/mailman/listinfo/linux-users

I have never spent any money to buy them, and having seen the construction I never will. One was a travelmate, their upper-range business class model with an all day battery. It worked well enough, but sometimes just misbehaved, crashing or freezing or rebooting. The owner was positive it had an anger sensor, cos the madder it made him the more it acted up. I thought pssht whatever but it turns out he was right - the mouse button microswitches were soldered directly to the mainboard not a daughterboard on the case. So whenever he got a bit angry he pressed the mouse buttons harder, which flexed the board resulting in general non-specific funkiness. I told the owner the cause, and admitted that he was kinda right. Has not let me forget it to this day --- Power sockets live longer if you avoid stowing the laptop with the power plug connected.This puts undue stresses on the plug/socket and makes it weak. Also avoid pushing laptop back when its plugged in, same reasoning. The fixes are 1) Get a dock and use it - only generally fits one model/brand of laptop. 2) Don't put the laptop in a bag with the PSU cable attached. 3) Use laptops with sideways plugs on the PSU, or magsafe style connectors. -- Criggie http://criggie.org.nz/ ___ Linux-users mailing list Linux-users@lists.canterbury.ac.nz http://lists.canterbury.ac.nz/mailman/listinfo/linux-users
