Basic mail functionality with attachments
by Mark Rogers 15 Oct '08

15 Oct '08

I'm sure I should be able to solve this one easily with help from Google but I've drawn a blank so far. I have a basic box installed with Ubuntu-server (8.04), pretty much a default install. I want to send a couple of files from that box as attachments by email. I'm looking for the minimum necessary to do this. I don't really see the need for a mail server (it just needs to do a DNS lookup for an MX record then SMTP direct to that). I have so far installed mutt but that's unable to send without something extra being installed. -- Mark Rogers // More Solutions Ltd (Peterborough Office) // 0845 45 89 555 Registered in England (0456 0902) at 13 Clarke Rd, Milton Keynes, MK1 1LG

Correctly configuring hostnames
by Mark Rogers 14 Oct '08

14 Oct '08

I'm sure this is trivial but all the info I've found online has been too vague to help me sort it. If I want a Linux box (Ubuntu/Debian) to have the FQDN of mybox.example.com, where do I set it? I understand that /etc/hostname should contain the "mybox" bit, but where does example.com go? I would expect the following queries and responses hostname -d Should give "example.com", gives "" (empty string) hostname -s Should give "mybox", and does hostname --fqdn Should give "mybox.example.com", gives "mybox" I even managed to get "hostname -s" to return "mybox.example.com" earlier, although I can't now reproduce it. NB: I do know that after changing /etc/hostname I need to run hostname -F /etc/hostname -- Mark Rogers // More Solutions Ltd (Peterborough Office) // 0845 45 89 555 Registered in England (0456 0902) at 13 Clarke Rd, Milton Keynes, MK1 1LG

RAM issues - Help!
by Steven Rose 13 Oct '08

13 Oct '08

I'd really appreciate any help on this matter, not really being all that knowledgeable in the hardware at hand. I am running a Gigabyte GA-MA69G-S3H (rev 1.0) motherboard with the latest BIOS, F6 I believe. The proc is AMD Athlon(tm) 64 X2 Dual Core Processor 4800+. The operating system at present being Ubuntu 8.04.1, fully updated and so forth. (http://www.gigabyte.com.tw/Products/Motherboard/Products_Spec.aspx?ClassVal…) The manual clearly states that the four DIMM slots run at a voltage of 1.8, this is also very clear in the CMOS settings. However, I have purchased a set of Corsair DDR2 800MHz XMS2 DHX, 2x2gb (http://www.ebuyer.com/product/142433) before realizing my potential issue. In the extended specifications it mentions something regarding 2.1 volts as it also does on the side of the heat-sinks. They are both currently in this particular machine and seem to be working fine, my concerns arise when running a memtest via GRUB. I have altered nothing in the BIOS merely replaced the old RAM and attempted to boot, which works fine, the memtest is stating something along the lines of 5-5-5-18, which I presume is related to the latency, however the RAM is branded as being 4-4-4-12, I am blissfully unaware as to whether it is running at the correct speed, or indeed voltage to work fully. Another point would be the system only displaying itself as having 3.2gigs rather than four, although this I presume could be normal as I am under 32bit userland. If my hardware will allow, of course, I wish to run this memory at its full capabilities. Any aid in this will be a great help. Cheers, Steve

Removing a disk drive, will it confuse things?
by Chris G 12 Oct '08

12 Oct '08

I want to remove one of the disk drives from my 'main' system (running Fedora 8). The drives on that system are currently:- /dev/VolGroup01/LogVol00 / ext3 defaults 1 1 LABEL=/boot1 /boot ext3 defaults 1 2 tmpfs /dev/shm tmpfs defaults 0 0 devpts /dev/pts devpts gid=5,mode=620 0 0 sysfs /sys sysfs defaults 0 0 proc /proc proc defaults 0 0 /dev/VolGroup00/LogVol01 swap swap defaults 0 0 /dev/VolGroup01/LogVol01 swap swap defaults 0 0 # # # Additions to see Fedora 7 partitions # /dev/sdb1 /f7boot ext3 defaults 0 0 /dev/VGa2/LVa2 /a2 ext3 defaults 0 0 /dev/VolGroup00/LogVol00 /f7 ext3 defaults 0 0 The disk I want to remove is /dev/sda which is (mostly) that /f7 mount point /dev/VolGroup00/LogVol00 (and also some of the swap). The two drives I'm leaving are currently /dev/sdb and /dev/sdc. I can see if all is well in terms of the contents of the drives by simply removing the two lines from /etc/fstab and rebooting, that will check that there's nothing needed for the system to run on /dev/sda. However will the resulting changed names of the underlying physical drives that (I presume) will occur when I remove /dev/sda cause any problems? I.e. will it stop the system booting/running? If so would it just be a matter of booting off a CD and going into single user mode to sort things out or is it messier than that? -- Chris Green

To install "stright-through" via CUPS??
by Ted.Harding＠manchester.ac.uk 10 Oct '08

10 Oct '08

Hi Folks, Confession: I've never had much luck with CUPS (as opposed to the old lpd system which I could get dancing to any tune)! Anyway: My printer is a PostScript-endowed HP 1300. I only ever produce PostScript files for printing. Therefore, I just want to be able to send the PostScript stream straight-through to the printer, i.e. not using any drivers. But when I try to set this up on CUPS (Gnome interface) it insists on going through the Maunfacturer/Driver routine. I've tried "Generic PostScript", and also "Apple Laserwriter II", installing PostScript drivers from the foomatic list. But the result is that, when I do 'lpr filename.ps', the printer starts printing reams of sheets with a single line of garbage on each. Don't ask me why! There's a complication, in that here I'm running Linux in VirtualBox on Vista, so there may be interference from Vista; but if I could get "straight-through" set up I think I should be OK. So, Question: How to set up straight-thorough in CUPS?

VNC Repeater
by Mark Rogers 10 Oct '08

10 Oct '08

If I have two Windows users, one needing to use VNC to view the desktop of another through various firewalls etc, what can I set up on a publically accessible (Linux) box to allow them to connect? Assume very little technical knowledge at each Windows end so I need to do something as simple as possible for them. The outbound connection from the vncserver end (the desktop that needs to be "seen" by the other end) will probably need to use some common port like 80 to get through the firewall, which will be fun as all my Internet servers have web servers on them, but I'll fall off that bridge when I come to it. The viewer end is marginally more technically capable (ie they'll follow instructions more carefully) than the server end. -- Mark Rogers // More Solutions Ltd (Peterborough Office) // 0845 45 89 555 Registered in England (0456 0902) at 13 Clarke Rd, Milton Keynes, MK1 1LG

Session saving not working - or am I confused?
by Chris G 09 Oct '08

09 Oct '08

I can't get Gnome to save sessions, at least I can't get it to do what I'm expecting it to do. Running Ubuntu 8.10 beta. I go to System - Preferences - Sessions and select the Options tab. There I'm presented with a selection box for "Automatically remember running applications when logging out" and a button which says "Remember Currently Running Application". Whichever I use *nothing* appears to be saved, i.e. if I log out leaving some terminals running they don't reappear when I log back in again. Am I misunderstanding what this is supposed to do or is it just totally broken? Google searches seem to suggest that it is supposed to do what I'm expecting but there don't seem to be any reports of it not working, even less of some sort of fix for it. -- Chris Green
