VNC problem
by Torben Stones 12 Mar '10

12 Mar '10

I'm having an interesting but very annoying problem. I have set up xtightvncserver (client) on one machine in listen mode, and then use x11vnc (server) on another machine. I connect the server to the viewer using the -connect argument. This works fine, as I can see the servers desktop on the client box as expected. Now I change my routers firewall rules to forward port 5500 to the client, and then try to connect the server to the client, again using the -connect argument, but this time using my external ip-address. This is where it gets odd. The vnc viewer on the client never seems to get a connection from the server. But if I look at the routers logs I can see that a message was received and matched against the correct firewall rule. I have used ngrep to find out if anything was appearing on port 5500 on the client, and I can see that there is indeed something coming in on port 5500. In ngrep it just appears as user@localhost:~$ sudo ngrep -d wlan1 port 5500 interface: wlan1 (192.168.0.0/255.255.255.0) filter: (ip or ip6) and ( port 5500 ) ### T 192.168.0.2:45401 -> 192.168.0.6:5500 [R] ...... ### T 192.168.0.2:45401 -> 192.168.0.6:5500 [R] ...... All this means to me is that something is appearing on port 5500, but as it isn't connecting then I can only assume that the wrong stuff is coming in. When I just use the internal address then I can see alot more on port 5500 for example the name of the display. Can anyone help me with the next step as I don't know what to do next. Thanks Torben -- You've got a lot of choices in your life. If getting out of bed in the morning is a chore and you're not smiling on a regular basis, try another choice.

OT: GPU fans
by Mark Rogers 12 Mar '10

12 Mar '10

The fan on the cheap PCI-X graphics card in my Linux box is failing. It's a little (40mm I think) fan mounted into the heatsink. Does anyone know if these can be replaced? It may only be a cheap card but it still seems silly having to pay for a new card just because the fan is dying! Or is there any way to rejuvenate a fan? -- Mark Rogers // More Solutions Ltd (Peterborough Office) // 0844 251 1450 Registered in England (0456 0902) @ 13 Clarke Rd, Milton Keynes, MK1 1LG

Recommendations: Linux Small Form Factor PC
by samwise 11 Mar '10

11 Mar '10

Hi, I'm considering building a small form factor PC to live under and output through my HD TV, primarily for running SDL games initially and I expect I'll stick some form of 64-bit Debian on it. I'm thinking a Mini-ITX size would be about right - something that will fit comfortably under the TV, but doesn't need to be too small. I'd like to stick in a pretty big hard drive (> 1 TB) and probably 4GB RAM at least. Graphics wise, I've had issues getting the official Nvidia binary drivers in the repositories working with Debian, but given it's intended use that's probably not reason enough to switch to ATI (binaries direct from Nvidia do work, albeit need manually updating every so often). I'd like it to support 802.11g wi-fi and preferably bluetooth internally (might require the use of a combo wifi/bluetooth internal card), and as many USB connectors on the front as I can get away with (4, 6?). Support for media cards etc. would be a nice bonus too. I've done some reading around but most hardware reviews don't generally cover linux compatibility, so just wondered whether anyone might have recommendations either for suitable PCs or suppliers I could be investigating. Cheers, Peter.

Samba share permissions
by Maz Walker 11 Mar '10

11 Mar '10

I meant to send this to the list but sent it to mark by mistake, sorry! Been lurking for a while so I guess this is hello! > Is there a better way for me to be connecting to the Linux-based server so > that I can access the same files that the Windows users are using through a > mounted share? Yes, the way we do it at work is like this [sharename] force group sambafiles force user sambafiles path = /where/it/is create mask = 0660 directory mask = 0770 writable = yes write list = @users You need to create a user and group called sambafiles that must not be used for anything else, you can control read and write to this share by using groups, all the files will be owned sambafiles:sambafiles which means all users in the allowed groups can read and write. maz

server startup
by Peter Alcibiades 11 Mar '10

11 Mar '10

Thanks to Mick for offline help. Meanwhile, can I ask for help on something which is so simple no-one seems to write about it? I have installed minimal debian, and then added the requisite stuff for nfs and cherokee and SSH. I'm fine with configuring both of them through the command line, and then in the cherokee case login in and using a web browser. Vi or emacs it will never be, but nano is fine. The command line in general is fine. Its just I never set up a server before. The thing I do not know how to do, is have the installation start up with nfs and cherokee at power-on. And I don't understand what the relationship is between the server function and user accounts. So, when I did the minimal install of Debian, I did one user and set up the root password, and also set up a separate home partition without knowing if this is right or wrong. Was that right? The result is two partitions, one about 10G for / and the other with the rest. Presumably the nfs area will be in the rest. But how do I tell it that? When the server starts, I think this is done by putting entries in init.d, yes? When it starts, does it start with a user login? Or is it running with no users logged in? It will be without screen or keyboard, so I am assuming I do SSH to the IP address. And then login as root? Or as the user? Oh dear, this is so basic. Once its done, it will be fine. I can write little scripts and use awk and manage the system from the command line with no problems, so once I know what to do it will be OK, but at the moment am rather peering into the mist. Peter

X authentication issue/question
by Chris G 10 Mar '10

10 Mar '10

I have a headless 'server' system which runs Ubuntu Server. Nearly all of the time I do maintenance, updates, etc. on the command line so it's just a matter of 'ssh server ....' to do what I need to do. However, occasionally, it's nice to use a GUI application to do something. Until now these have always needed root on the server system and the following sequence works OK:- chris$ ssh -X server chris@server:~$ sudo -s [sudo] password for chris: root@server:~# <run GUI program> The trouble is that when I try to do the same for a non-root user on the server system I get:- chris$ ssh -X server chris@server:~$ sudo -s root@server:~# su www-data www-data@server$ sqlitebrowser X11 connection rejected because of wrong authentication. sqlitebrowser: cannot connect to X server localhost:12.0 I have xhost allowing the following:- chris$ xhost access control enabled, only authorized clients can connect NIS:www-data@server NIS:root@server SI:localuser:chris SI:localuser:gdm SI:localuser:root So why can root GUI programs display on my screen while non-root GUI programs can't? I've tried 'xhost +' to allow anyone to connect but I still get the same error. $DISPLAY is correctly carried through the various logins, I've checked that. Also www-data is the same UID on both systems though I don't really see why that would be relevant. OK, I *could* run sqlitebrowser as root (I have tried and it works OK) but I then end up with lots of files having wrong permissions, it would be much nicer if I could run it as www-data. -- Chris Green

Any sqlite (ot other SQL database) experts here - how to copy a table?
by Chris G 10 Mar '10

10 Mar '10

It sounds like it should be easy but I can't see any reasonable way of doing it. How do you make a copy of a table in an sqlite3 database? I can copy the database, that's trivial, but I want to duplicate a *table* within a database and that seems distinctly un-trivial. Any ideas/suggestions anyone? -- Chris Green

Recommend a DNS Provider?
by Greg Thomas 09 Mar '10

09 Mar '10

For a number of years, I've been happy with my hosting provider, 1&1. I've only really got two complaints; a) Lack of IPv6 support. Hopefully that will come in time, and b) They only support 10 sub domains for each DNS domain you have with them. It's the second that looks like it may begin to bite soon. Can anyone recommend a reliable DNS provider that will allow me an order of magnitude more subdomains (*) if I move my DNS to them? TIA, Greg (*) OK, so 20 would probably be enough for the forseeable future, but then I thought we;'d never get near 10 ...

Moving mailboxes
by Chris Walker 08 Mar '10

08 Mar '10

Ive just bought myself a new machine and am wanting to move the mailboxes from this one to the new one. This one runs Mandriva 2010.1 and the new one runs the 64 bit version of it. I use both Sylpheed and Thunderbird on here so need to know how best to do it. Both machines dual boot and I've sort of managed it for Sylpheed under Windows XP and completely for Thunderbird on XP. Half the messages are missing on Sylpheed though and none of the accounts have transferred. I chose Sylpheed for XP as it started life on *nix and to date it's been much more reliable than Pegasus which is what I used before. But I want to avoid the same problem under Linux that I've just encountered under XP -> 7. Any help appreciated.
