Re: Torrent Problems

Same for me with Transmission in Ubuntu 12.04. I noticed that my files were old, so I remove the old files and added the new torrents to Transmission a night or two ago. They downloaded, and appear to be somewhat uploading, but I still get that tracker error today.

Re: Unable to SSH

Raspbian creates new /etc/ssh/ssh_host_* (key) files the first time it boots. So once I have booted an SD card I use Ubuntu Linux to copy the same set of those host key files to the SD card. I give each SD card a different hostname in /etc/hostname and /etc/hosts, but since they all have the same ss...

Re: Files from Windows discs to Pi

Note that USB memory sticks or memory card readers connected directly to the Pi work best if connected "before" booting. If you try to hot plug them while already running, the momentary current draw may cause the Pi to reboot. That is probably not an issue when using a powered USB hub.

Re: Control via laptop but show output on TV?

There is something called synergy in the Raspbian repos, which I somehow got to work from my keyboard in Ubuntu Linux on a PC when it was also installed in that. If you are able to set it up properly to work in X (lxde) on the Pi, it allows you to control either your PC or the Pi from the keyboard o...

You do not need to erase or format anything.

The write protect switch should be towards the SD contacts. I have on microSD to SD adapter where t...

Re: Is broadcasting SSID mandatory?

The ESSID is included in the clear in wireless traffic whether broadcast or hidden, so it is easy to sniff it out when there is "any" wireless traffic. How else would an access point know what wireless traffic to respond to? But hiding the ESSID can result in delays, because clients cannot tell if t...

It sounds like you have a DSL bridge modem. PPPoE does not use an "ethernet" IP, its tcp/ip is inside the PPPoE tunnel.

All that matters is that is supplies around 5 VDC and is rated for " enough " current. It will not use more current than it needs. For example I have a 4000 mAh battery pack rated up to 2.1 A out (enough for an iPad), which if you used that much would last less than 2 hrs (4 Ah / 2.1 A = 1.9 hr ). B...

Re: no display on brand new pi

Measure voltage across T1 and T2 to check if it is getting enough (over 4.75V). But only 2 flashes on green LED sounds like it is not even booting. Normally the green LED should flicker awhile while it boots, so maybe the image was not properly written to the SD card.

Re: How to set Terminal window size?

I thought the terminal is normally centered in X. If you want to change its size, based on man lxterminal, if you want to change its size, look for EXEC= in the desktop shortcut and add a parameter (just the 1st line):

Code: Select all

--geometry=CHARACTERSxLINES
  Set the terminal's size in characters and lines.
