ALUG Announce Please send announcements to Announce(a)lists.alug.org.uk Unsub, change settings via http://lists.alug.org.uk/mailman/listinfo/announce ----- Hello Norwich Aluggers, Our monthly ALUG Norwich social meeting will be held this Thursday, 11th October at The Coach and Horses (82 Thorpe Road, Norwich, NR1 1BA). The meeting officially starts at 8pm, although some people may arrive earlier. More information on those people can be found on the list and the IRC channel. If you are unsure if you will recognise us then make yourself and your intent to attend known by either posting on list or visiting us on IRC so we can look out for you rather than hiding in the corner. Optionally you could ask at the bar if they know where the geeky computer weirdos are and they'll point you in the right direction (seriously!). Another possibility is look for heaps of electronics on a table that may possibly look like movie props that would used for detonating explosives. Feel free to bring electronics/laptops/gadgets to the meet, you will by no means be alone. Ben Bewick aka Viperfang NB: This mail is automated, please refer to the usual sources for more information.

I nearly have a VPN working, but I can't get any data through it
by Chris Green 06 Oct '12

06 Oct '12

Well I'm having a wonderful time playing with ideas to access the web server on my eeePc on the boat. My home router is a Draytek Vigor 2820n which has VPN capability itself. So I decided to try it. I can connect using pptp from the eeePc on the boat to the 2820n's VPN service:- root@eeepc:~# pptpsetup --create home --server zbmc.eu --username chris --start Password: Using interface ppp0 Connect: ppp0 <--> /dev/pts/1 CHAP authentication succeeded Cannot determine ethernet address for proxy ARP local IP address 192.168.1.202 remote IP address 192.168.1.1 root@eeepc:~# ... and I can then ping the router from the eeePc OK. However I can't get anything else to work, i.e. I can't seem to get any data across the VPN connection at all. I have tried adding a route at the eeePc end:- root@eeepc:~# route add -net 192.168.1.0 netmask 255.255.255.0 dev ppp0 root@eeepc:~# route Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 192.168.1.1 * 255.255.255.255 UH 0 0 0 ppp0 84-45-228-40.st 192.168.13.1 255.255.255.255 UGH 0 0 0 eth0 192.168.1.0 * 255.255.255.0 U 0 0 0 ppp0 192.168.13.0 * 255.255.255.0 U 0 0 0 eth0 default 192.168.13.1 0.0.0.0 UG 100 0 0 eth0 root@eeepc:~# but still no joy. root@eeepc:~# ping 192.168.1.1 PING 192.168.1.1 (192.168.1.1) 56(84) bytes of data. 64 bytes from 192.168.1.1: icmp_seq=1 ttl=255 time=82.0 ms 64 bytes from 192.168.1.1: icmp_seq=2 ttl=255 time=76.7 ms 64 bytes from 192.168.1.1: icmp_seq=3 ttl=255 time=79.6 ms 64 bytes from 192.168.1.1: icmp_seq=4 ttl=255 time=77.8 ms 64 bytes from 192.168.1.1: icmp_seq=5 ttl=255 time=76.6 ms 64 bytes from 192.168.1.1: icmp_seq=6 ttl=255 time=74.9 ms ^C --- 192.168.1.1 ping statistics --- 6 packets transmitted, 6 received, 0% packet loss, time 5007ms rtt min/avg/max/mdev = 74.905/77.992/82.087/2.345 ms root@eeepc:~# ping 192.168.1.4 PING 192.168.1.4 (192.168.1.4) 56(84) bytes of data.

Do most/all 'real' SMTP servers follow reasonably retry strategies?
by Chris Green 05 Oct '12

05 Oct '12

As per the subject line, do most SMTP servers (as in systems 'out there' which send me mail) behave reasonably sensibly when my SMTP server is temporarily not functioning? I currently have both a desktop machine *and* a small server machine which are on all the time. It's the server machine that receives my E-Mail. The only reason I have it configured this way is because I'm more likely to rebuild/reconfigure my desktop machine than the server machine and I felt that keeping my SMTP server online consistently was important. However I'm wondering if the effort (and cost) of running two systems all the time is worth it. The other functions of the server system (DNS and CUPS) can easily be run on my desktop machine, occasinal downtime of those services is easily explained to other family members! :-) If real world SMTP servers 'out there' will cope quite happily with my domain's MX machine being AWOL for several hours then I may as well put everything on the one server machine. (Note it's only *my* E-Mail that is delivered by SMTP, all other family members do their own thing as in use Webmail, or IMAP, or whatever) -- Chris Green

WiFi range, what am I likely to get outdoors line-of-sight, without special equipment?
by Chris Green 26 Sep '12

26 Sep '12

The subject says it all really, what sort of range is one likely to get outdoors with WiFi? It's basically line of sight, base station is in a shop, my WiFi router will be sitting in a window maybe 200 meters away. Do I have any chance of it working? -- Chris Green

Catch 22 situation when disk gets full - how to solve?
by Chris Green 23 Sep '12

23 Sep '12

I have a sort of Catch 22 situation on my little eeePc. It has tried to update kernels automatically and, after a few months (it's on our boat doing monitoring) it has run out of disk space. It still runs OK and I can ssh into it. It has quite a long list of old kernels installed but I can't delete them to make space because it has half an update of the latest kernel:- So when I try and do anything with apt-get I see:- root@eeepc:/var/lib# apt-get remove linux-headers-2.6.32-39 linux-headers-2.6.32-39-generic-pae linux-image-2.6.32-39-generic-pae Reading package lists... Done Building dependency tree Reading state information... Done You might want to run 'apt-get -f install' to correct these: The following packages have unmet dependencies. linux-headers-generic-pae: Depends: linux-headers-2.6.32-43-generic-pae but it is not going to be installed E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution). So how do I uninstall all the old headers etc. so that there *is* space to do things? -- Chris Green

by Steve Engledow 17 Sep '12

17 Sep '12

Hi folks, Excuse the flagrant abuse of this mailing but I feel the crossover of interest is worth it. The first Norwich Maths Jam (see http://mathsjam.com) begins tomorrow evening (Tuesday 18th) at 7pm in The Reindeer pub on Dereham road; coincidentally a previous haunt of the ALUG pub meet :) If you fancy coming to a pub and being geeky in a mathsy way, come down! Remember kids, beer + geekery -> fun. Steve

apt-get problems
by Greg Thomas 16 Sep '12

16 Sep '12

I just tried upgrading from Ubuntu 10.04 to 12.04.1 (i.e. from LTS to LTS). It failed. The error message I'm getting is: An unresolvable problem occurred while calculating the upgrade: The package 'update-manager-kde' is marked for removal but it is in the removal blacklist. Google suggests that "apt-get remove update-manager-kde" should fix it [1], but that's giving me the following; Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming. The following information may help to resolve the situation: The following packages have unmet dependencies. libasound2: Breaks: libasound2-plugins (< 1.0.24) but 1.0.22-0ubuntu6 is to be installed libglib2.0-0: Breaks: gnome-control-center (< 1:3) but 1:2.30.1-0ubuntu2 is to be installed Breaks: gvfs (< 1.8) but 1.6.1-0ubuntu1build1 is to be installed libgnome-keyring0: Breaks: gnome-keyring (< 3.0) but 2.92.92.is.2.30.3-0ubuntu1.1 is to be installed libpango1.0-0: Breaks: plymouth (< 0.8.2-2ubuntu19) but 0.8.2-2ubuntu2.2 is to be installed ppp: Breaks: network-manager (<= 0.8.0.999-1) but 0.8-0ubuntu3.3 is to be installed Breaks: network-manager-pptp (<= 0.8.0.999-1) but 0.8-0ubuntu3 is to be installed E: Broken packages Have I completely hosed my setup, and is a fresh re-install due? Or is there a way around this? Thanks, Greg [1] http://www.hoaglun.com/blog/2011/5/8/ubuntu-1010-1104-upgrade.html
