xemacs
by Allan Duncan 07 Apr '14

07 Apr '14

Without starting an editor war [ :-) ], I'd like some help in getting xemacs to play ball. I'd like to give xemacs a try, but I can't get it to recognise the font I want to use (dejavu sans mono) doesn't appear in the "available" list. Liberation mono does, however. Here are their entries in their font.scale files: LiberationMono-Regular.ttf -misc-liberation mono-medium-r-normal--0-0-0-0-m-0-iso8859-1 DejaVuSansMono.ttf -misc-dejavu sans mono-medium-r-normal--0-0-0-0-m-0-iso8859-1 As far as I can see from the docos they both have the right form. Btw, there is a message "Warning: Missing charsets in String to FontSet conversion" Any suggestions? TIA.

LXC & Docker management software
by Toby Corkindale 04 Apr '14

04 Apr '14

Hi, Does anyone know of some high-level management software for running LXC (preferably Docker) containers across clusters of machines? Eg. So you can have a central control centre to see what's running, what resources it has allocated, and an API to spin up new app instances. Basically private cloud stuff, but lightweight rather than enterprisey.. Closest I've seen so far has been Flynn, but that's still a way off. -Toby

Debian 7.0 install question
by zlinw＠mcmedia.com.au 04 Apr '14

04 Apr '14

Just did an install of Debian 7.0 from DVD's onto a system using an ASUS X79 Sabertooth motherboard. Now the bios is set to IDE mode (NOT AHCI), this is due to Windows xp as an alternate OS Had some trouble until I disabled secure boot (uefi or what ever they call it). On completion of install system failed to boot, it was clear though that the reason was the installed kernel was using the AHCI drivers. After setting the bios to AHCI mode system booted OK. A couple of questions..... Why during the install did the installer set the intial ramdisk up for AHCI drivers when they were not enabled in the bios. Can Debian 7.0 be installed on a system with ide mode enabled, if so how does one do this. A search on the net was not enlightening. This is not any kind of disaster, I will be compiling my own kernel for this machine (in fact I have already done so) so one can easily get around this issue. Note 1, Sometime back I did a comparison on an ASUS P6X58D Premium MB between IDE and AHCI modes, a good deal of testing showed neither mode was head and shoulders over the other. Lindsay

Upgrading to LibreOffice 4.2.2 on Ubuntu 10.4
by Carl Turney 02 Apr '14

02 Apr '14

Hi All, I'm trying to upgrade my LibreOffice from 4.0.2.2 to 4.2.2, on my Ubuntu 10.4 Desktop. (Yes, yes, I'll upgrade to Ubuntu 14.4 as soon as I get more powerful hardware and it comes out stable in April.) I followed the instructions here, which seems the most authoritative (it said nothing about upgrading, just installing): > https://wiki.ubuntu.com/LibreOffice#Installing_a_newer_version_of_LibreOffi… (I followed the steps in the above-cited section, as normal Synaptic updates stopped a long time ago on my system.) But when I executed this command... sudo apt-get update ...I got (among others) this message: W: Failed to fetch http://ppa.launchpad.net/libreoffice/libreoffice-4-2/ubuntu/dists/lucid/mai… 404 Not Found So am I correct in assuming that I can't upgrade LibreOffice to 4.2.2 on my Ubuntu Lucid? Thanks very much, Carl Turney Bayswater

throttle removed from FreeBSD ports - alternatives?
by Peter Ross 01 Apr '14

01 Apr '14

Hi all, I am using "throttle" for snapshot backups. It is a small utility reading from stdin and writing to stdout and used to limit the speed (to avoid "hammering" of disks and networks) E.g. "throttle -1M" reads 1 MByte/sec. Unfortunately this utility was removed from the FreeBSD ports. I do not know the background. It is nowhere maintained anymore, it seems (if I get the change log right, it was part of a "bulk retirement commit" in FreeBSD) I am exploring and considering options.. Do you know any alternatives? Regards Peter

ipsec not routing packets
by James Harper 28 Mar '14

28 Mar '14

I have a linux router set up like 10.x.x.A/32 | 203.x.x.B (linux router) | {Internet} | 203.x.x.C (other IPSEC gateway, not sure of brand) | 10.x.x.D/29 And an ipsec tunnel set up with endpoints 203.x.x.B and 203.x.x.C, and the tunnel 10.x.x.A/32 - 10.x.x.D/29 If I ping from D->A, I see the ping reach A, the response reach B on the way back, but is never sent from B->C, either encrypted or not. If I ping from A->D, same thing, the packet is never sent from B->C. I have a route for 10.x.x.D/29 on B pointing towards B's default gateway. I have excluded 10.x.x.D/29 from any nat or mangle transformations in iptables, but still nothing. tcpdump definitely shows no corresponding send from B->C when a packet is sent from A->D. There is no other traffic that would occur from B->C so it's fairly easy to determine that no traffic is being sent. The linux router is debian wheezy, running Debian 3.2.0-4 kernel (3.2.54-2). IKE is being done by racoon, and all appears correct. Setkey appears to show the correct SA's, it's just that nothing gets forwarded towards the other end. Any and all suggestions for fixes appreciated! Thanks James

At least on the Linux side you can script that (auto-generating an e-mail with a file as an attachment) Setup a little local mail server and create an account for the iOS device. I tried once an SSH client on an iPad but it gave me some errors when trying to connect to the Ubuntu box. I was not persistent enough to figure out why (I hate Apple devices with a passion because of the lock-up/lock-in and complete surveillance issues - but the kids' schools insist:-( Regards Peter

Filesystem becomes readonly.
by Daniel Jitnah 26 Mar '14

26 Mar '14

Hi LUVers 1.Linux (Debian Wheezy) running on a cloud server 2.Everything working fine for weeks/months 3.Last nite, for some reason all disk writes to server stops 4.Even root cannot write to anywhere on the disk, and plenty of space left on disk (~80%) All file permissions look OK. 5.After reboot all return to normal.(ie problem is fixed) My questions: Is it fair to assume that the problem was caused by something that the cloud provider has done? Or could it be something on server OS side? What can cause this? (I am thinking the virtual disk hosting the VM has become readonly somehow, but how? ) Cheers Daniel.

The performance of the ZFS became very bad - resulting in disk write timeouts in the Ubuntu VM. The Ubuntu server assumed a faulty disk and remounted the disk as read-only to prevent further damage. Although you are very unlikely to have FreeBSD/ZFS underneath there are other ways to "produce" high I/O latency. If so you should find these disk I/O related errors in your kernel logs. I am afraid there is not much you can do (if you do not run the host system). It only needs a short period with this problem and your system becomes unresponsive. Monitoring.. I did not do that for the read/only mount but all services running on that VM turned red on the Icinga webpage. Regards Peter
