Possible Chess moves
by Ted.Harding＠wlandres.net 11 May '13

11 May '13

Greetings All! I have a query. Is there some program which, given a Chess position and which player has the move, can output a (preferably numbered) list of the possible moves for that player in that position? Ideally, it should be possible to enter the position by placing pieces on an image of the board (and to change the position by moving pieces, e.g., after a move, by making the move). With thanks, and best wishes to all, Ted. ------------------------------------------------- E-Mail: (Ted Harding) <Ted.Harding(a)wlandres.net> Date: 11-May-2013 Time: 12:23:02 This message was sent by XFMail -------------------------------------------------

"Highly visible"
by Max Folker 08 May '13

08 May '13

Hi, I'm new here and would like to come along to the Norwich meeting this Thursday. This page (http://alug.org.uk/PubMeetings) says: "New Members are advised to arrange contact (swapping telephone numbers etc) or ask for us to make ourselves highly visible, so you don't end up sitting at a table full of random strangers who aren't interested in Linux." ...I'm not sure if this is the right place to ask, but yes - if the group could possibly be highly visible that'd be great. Hopefully see you there. : ) - Max

Where am I going wrong?
by Chris Walker 08 May '13

08 May '13

I have 2 mail readers on this machine, Thunderbird (which is what I'm using to write this mail) and Sylpheed. I also have a Blackberry Playbook which is configured to use one of the same email addresses as used on Sylpheed. I had previously used Sylpheed in POP3 mode but when I realised that it wasn't displaying the mail I'd sent from the Playbook, I figured I'd change the setup to IMAP. Sylpheed wouldn't let me change it so I deleted the account and recreated it as IMAP. But Sylpheed still won't display the sent mail. I then looked around for another free mail reader and found Claws. If I set that up in IMAP mode, it *does* show the sent mail. Further googling showed that Claws was developed from the same code base as Sylpheed so if one program can display the sent mail, why won't the other? Any help/ideas appreciated.

Qemu networking
by Barry Samuels 08 May '13

08 May '13

I have been using Qemu on my Debian machine running Windows XP for some years including being able to access a directory on the Debian system using Samba from Qemu. Qemu was updated in the recent past and the networking/Samba side of things stopped working. Well, actually, the command line I had been using to start Qemu was no longer accepted and Qemu wouldn't start until I removed the networking bit. I have been struggling to get it going again ever since. I can get Qemu to run but I can't get the networking/samba side to work. My original Qemu command was: /usr/bin/qemu -boot c -m 256 -hda '/usr/local/storage/qemu/win-xp2.img' - cdrom '/usr/local/storage/qemu/mm.iso' -hdb '/usr/local/storage/qemu/win- xp3.img' -net nic,model=rtl8139 -net user,vlan=0 -smb Linux -redir tcp:9100::9100 -soundhw sb16 -localtime -usb -usbdevice host:067b:2303 - usbdevice host:04b8:0005 The current Qemu command is: /usr/bin/qemu -boot c -m 256 -hda '/usr/local/storage/qemu/win-xp2.img' -cdrom '/usr/local/storage/qemu/mm.iso' -hdb '/usr/local/storage/qemu/win- xp3.img' -netdev type=user,id=mynet0,smb=Linux_m,smbserver=10.0.2.4 Qemu starts but I get no access to the network. I get the following message: 'An error occurred while connecting L: to \\10.0.0.2\linux' Not particularly helpful. I also see sometimes 'The network cannot be reached'. I'm sure I used to have an entry of some sort in the Windows Hosts file but the entry is not there now and I don't remember what it was. Searching on the internet has not provided any useful information. Can anyone offer any help please? -- Barry Samuels http://www.beenthere-donethat.org.uk The Unofficial Guide to Great Britain

BASIC and Linux
by Bev Nicolson 04 May '13

I'm not asking for myself by the way. Would it be possible to run BASIC and create programmes in Ubuntu? A quick Google suggests WINE would be necessary. Thoughts? (Other than 'Why would you?') Bev.

SAMBA vs NFS
by steve-ALUG＠hst.me.uk 03 May '13

03 May '13

Hi Guys, I tried setting up NFS last night and I got it to work, but it was so slow compared to the Samba share I used to use. I've been meaning to try and set up NFS for ages. I was thinking that it was probably the best way to share files between my server and laptops, maintaining appropriate Linux user names/rights etc for files, rather than the kludgey way I have my Samba set up. I got it working using http://czarism.com/easy-peasy-ubuntu-linux-nfs-file-sharing and then I looked at https://help.ubuntu.com/community/SettingUpNFSHowTo and I was trying to make it a bit more secure by editing hosts.deny/allow as described. Sometime during this modification, I managed to break it completely. So my questions: Is nfs the way to go to share files & directories from a server to laptops, or should I stick with Samba? Is the Ubuntu link above a sensible way of setting things up? I was thinking I'd just manually keep the user names/numbers in sync between the computers - is that OK? Is there a better way of doing things? I think it's stopped working because rpcbind can't link to localhost. I think I know how to fix it, but can't spare the time at the moment. Any thoughts? Thanks in advance! :-) Steve

I have done C# development on Linux using Mono and confirm that this works well. It now looks like Mono is starting to support Visual Basic on Linux (http://www.mono-project.com/VisualBasic.NET_support#New_Visual_Basic_Framew…) which I haven't tried, but based on the C# experience I would expect that it would be good.

iptables question
by Mark Rogers 01 May '13

01 May '13

I have an Internet facing server running pptpd. Users who connect via pptp need to be able to route through the server to the rest of the Internet. As well as configuring net.ipv4.ip_forward=1 I also have iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE .. and it all works. However, is the above iptables command too broad for an internet server? Doesn't it effectively mean that anyone can send traffic through it? Assuming the pptp interface is ppp0 I would have expected (having very little iptables knowledge) that: iptables -t nat -A POSTROUTING -o eth0 -i ppp0 -j MASQUERADE .. would be better but I'm just guessing and I don't want to kill access to the remote server by playing! Given that every howto I find says to use just "iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE" I assume that's actually right, so I think I'm just asking for help understanding why.
