Network printing again
by Chris Walker 25 May '13

25 May '13

I'm having another try at making network printing work. I bought a Buffalo ADSL router recently with the facility to print using the inbuilt USB port. I connected up the printer and tried to make my system see the it. But it never does. If I set the host address as 192.168.1.1, the system picks the port number as 9100. I've looked on the router and all I can see is a WebAccess External Port set to 9000 so I'm guessing that 9100 isn't likely to be about right. The router can also be used as a media server with a USB disc plugged in instead of the printer. If I do that, the disc is seen as smb://ap0024a5bdb4dc/disk1_pt1/ and I can see and read the files (the buffalo is seen on a wifi network as Buffalo-BDB4DC so that ties in too). But I'm still stuck as to why I can't print. Can anybody suggest a way forward please?

Fire FTP trying to confuse me...
by Anthony Anson 23 May '13

and succeeding. Up to this morning Fire FTP has been intuitive and easy to use, however, from having a local and a remote side in separate panes on the same page, it has taken the liberty of listing everything on one side, and only having an upload arrow - no download one. I may have accidentally clicked something which has brought this about, but I can't find anything to restore the default position. Any ideas? -- Tony http://www.girolle.co.uk/

DHCP Error
by steve-alug＠hst.me.uk 21 May '13

21 May '13

Hi folks, I'm confused about another thing too. I have an external backup drive, connected via a network cable. When things boot up, it gets IP addresses for its drives from my dhcp server. This used to work fine. Recently however, I find that the drive's complaining of a "DHCP network addressing problem" (according to the blinking light code!). If, before the drive boots I disable my UFW firewall with sudo ufw disable, then boot the drive, then enable the firewall, everything's OK. If I don't disable the firewall while the drive's getting an IP address, I get the error. I'm running dnsmasq as a dhcp server. My ufw rules are like this $ sudo ufw status Status: active To Action From -- ------ ---- 67 ALLOW 169.254.0.0/16 68 ALLOW 169.254.0.0/16 67 ALLOW 0.0.0.0 68 ALLOW 0.0.0.0 192.168.55.66 ALLOW 192.168.55.0/24 I've omitted 4 rules which open up specific ports, with a format like this as they're not relevant (at least I think they're not relevant) 192.168.55.66 123 ALLOW Anywhere 192.168.55.66 456/tcp ALLOW Anywhere As I understand it, the ports I need to allow access to are 67 and 68. When something asks for an IP address and it hasn't already got one, it broadcasts from the broadcast address 0.0.0.0. Sometimes, a machine will assign itself an IP address in the 169.254.0.0/16 range - e.g. a Windows machine that can't find a DHCP server on the network. If I allow this range then such machines can contact the DHCP server. The final line should allow anything with an address in the range 192.168.55.0 - 192.168.55.255 to contact any port on my server 192.168.55.66, which is where the DHCP server is. It seems to me I must have something wrong with the UFW rules, otherwise why would disabling it allow the drive to get a DCHP lease? What have I got wrong? Any ideas appreciated. Cheers Steve

Hi All, I'm Not sure how many people know about the following here already, and hope fully this isn't against any list etiquette rules; I'm sure many of you use the various Stack Exchange sites, such as http://serverfault.com/, http://stackoverflow.com/, http://unix.stackexchange.com/ and http://askubuntu.com/. Now there is a new site that recently came out of Beta for public access, http://networkengineering.stackexchange.com/. If anyone has networking questions I urge you to sign up and start asking! If the site doesn't get enough traffic in this initial stages it could get shut down, and so far it is proving to be a great well of knowledge. Many thanks, James.

Debian linux 3.8 and grub
by Richard Lewis 18 May '13

18 May '13

Hi ALUG, I recently upgraded my Debian unstable system and it included the 3.8 Linux kernel. There seem to be some problems with this kernel and my wireless network card. So I just want to set the old 3.2 kernel as the default boot option for now. However, setting: GRUB_DEFAULT=2 in /etc/default/grub and running update-grub seems not to have taken effect (the 3.8 kernel still gets booted). I notice GRUB now seems to have a new initial menu with just two options (paraphrased): "Boot Debian"; "Advanced Options". Selecting Advanced Options presents the more familiar list of kernels to boot. Where did this new menu come from? Could it be interfering with my GRUB_DEFAULT=2 option? Is there a way to remove it? Or any other suggestions why my default kernel option may not be working? Thanks, Richard -- -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Richard Lewis j: ironchicken(a)jabber.earth.li @: lewisrichard http://www.richardlewis.me.uk/ -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-

Claws mailbox over quota?
by Chris Walker 14 May '13

14 May '13

Following a query from Mick, I decided to try importing all my mail from Thunderbird into Claws (v3.8.0) and it's all been going well until I tried to import a mailbox from 2009. The messages in the import folder total 399 and yet there are only 350 in the imported folder. I clicked on the red exclamation mark at the bottom of the Claws window and it tells me '*** IMAP4< Alert: Mailbox is at 99% of quota' but despite searching everywhere I can, I can't find any mention of quotas. Can anybody help please?

Routers
by Chris Walker 12 May '13

12 May '13

Hello, Does anyone have a need for either one or two BT Home Hubs? They're V2 and I've hacked them to enable use on something other than a BT line. They have 'n' wifi and I've had them working on my Talktalk line as a test. They belonged to one of my sons who moved house and wanted to remove clutter from the new home. Good old Dad will take them! If nobody wants them, I'll bung them on ebay and if nobody there wants them, they'll go for recycling. I'm in Wymondham near Norwich but might be prepared to travel within Norfolk/Suffolk/Cambs.
