Mini PC for Home Office?
by phiscock＠ee.ryerson.ca 05 Mar '15

05 Mar '15

I'm considering the Zotac and Asus mini-pcs for the basis of a home-office system. It won't be used for gaming, just spreadsheets, word processing and internetting. I'm looking for a box with a bunch of usb ports, hdmi port, wired network connection. Wi-fi and a second hdmi port would be a bonus. Has anyone installed Linux Mint on one of these types of machines? Thanks - Peter -- Peter Hiscocks Syscomp Electronic Design Limited, Toronto http://www.syscompdesign.com USB Oscilloscope and Waveform Generator 647-839-0325

Netbook or used Mac?
by David Collier-Brown 05 Mar '15

05 Mar '15

I have an elderly relative who is having real trouble trying to learn how to use a iPad. Over about five years, she got to be able to write a monthly newsletter for the Ratepayers Association and do email on a Mac, but still had trouble browsing the web or doing anything more complicated. She can do economic tradeoffs in her head, but has no intuition about computers. Her iMac died, and she tried an iPad, but is having /even more trouble/ than with the mac! The mention of thin clients here made me wonder: would she be better just buying a new mac, or are there netbooks or thin clients that would seem "just like the mac with different icons" ? --dave -- David Collier-Brown, | Always do right. This will gratify System Programmer and Author | some people and astonish the rest davecb(a)spamcop.net | -- Mark Twain

Spring Cleaning
by Ansar Mohammed 03 Mar '15

03 Mar '15

Once again, I have accumulated a large collection of computer parts. THIN CLIENTS (these were hand picked by me; they are essentially x86 boxes that can run Linux or FreeBSD) probably about 10 hard drives of pretty much everything you can imagine. 2.5/3.5 SATA IDE and a few SCSI (no SAS) Laptops (some working, some for parts) Lots of Memory (various quantities) too much to categorize Motherboards Cases Power supplies Every type of cable known to mankind IDE, SATA, USB, Floppy SCSI. The vast majority of these items are in working order. There may be a few that don't work because they have been in storage for a while. If you are looking for a specific item, I may be able to help you, if not I would prefer the lot go to someone who can make use of this instead of going into a landfill.

2 networks under ip (iproute2)
by Walter Dnes 02 Mar '15

02 Mar '15

This is frustrating, because it works for me under ifconfig, but not under ip (iproute2). I have 3 devices in this scenario... * my desktop PC 192.168.123.251/29 * an HDHomerun TV tuner that comes up in the 169.254.0.0/16 block * the ADSL router/modem at 192.168.123.254/29 to which the PC and the tuner are connected. I'm trying to get my desktop PC to talk to the TV tuner using ip. What am I doing wrong in the following set of commands? ip address flush dev eth0 ip link set eth0 down ip link set eth0 up ip address add 192.168.123.251/29 dev eth0 ip route add default via 192.168.123.254 ip address add 169.254.1.1/16 dev eth0 ip route delete 169.254.0.0/16 dev eth0 ip route add 169.254.0.0/16 via 192.168.123.254 ip address show ip route show The ouput from the 2 "show" commands is... 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 brd 127.255.255.255 scope host lo valid_lft forever preferred_lft forever 2: eth0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc pfifo_fast state DOWN group default qlen 1000 link/ether 00:1d:09:96:6c:1c brd ff:ff:ff:ff:ff:ff inet 192.168.123.251/29 scope global eth0 valid_lft forever preferred_lft forever inet 169.254.1.1/16 scope global eth0 valid_lft forever preferred_lft forever default via 192.168.123.254 dev eth0 127.0.0.0/8 dev lo scope host 169.254.0.0/16 via 192.168.123.254 dev eth0 192.168.123.248/29 dev eth0 proto kernel scope link src 192.168.123.251 -- Walter Dnes <waltdnes(a)waltdnes.org>

SSH Hangs
by Dev Guy 02 Mar '15

02 Mar '15

Hi All, I am having a real nagging problem with ssh. I setup dynamic dns so I could I connect to my box from outside. My basic setup is a router connected to a cable modem. I've opened the firewall port 22 tcp/udp on my router. However he is the problem I am having. I can ssh into my box from inside my LAN like, ssh 192.168.0.100, works fine! However when I try to ssh using my dynamic dns (or the external IP), ssh will hang and never return. 1) I've tried running my sshd in debug mode and here is the output =====(SERVER SIDE)===== debug1: sshd version OpenSSH_6.6.1, OpenSSL 1.0.1f 6 Jan 2014 debug1: key_parse_private2: missing begin marker debug1: read PEM private key done: type RSA debug1: private host key: #0 type 1 RSA debug1: key_parse_private2: missing begin marker debug1: read PEM private key done: type DSA debug1: private host key: #1 type 2 DSA debug1: key_parse_private2: missing begin marker debug1: read PEM private key done: type ECDSA debug1: private host key: #2 type 3 ECDSA debug1: private host key: #3 type 4 ED25519 debug1: rexec_argv[0]='/usr/sbin/sshd' debug1: rexec_argv[1]='-d' Set /proc/self/oom_score_adj from 0 to -1000 debug1: Bind to port 22 on 0.0.0.0.

Someone suggested that sshd might be trying to do a reverse lookup and to add, 'UseDNS no' to /etc/ssh/sshd_config and restarting the daemon. This didn't work! Any ideas? I can't seem to find anything for my particular problem on the Internet.
