The meeting topic for this month is as follows: Wireless Theory and Regulations Wyatt Zacharias will be doing a presentation on wireless theory and regulations, and how they pertain to the average user. Wyatt will be breaking down the basic units and calculations related to wireless networks and how they can be used by an unlicensed user. RTFM In the RTFM segment this month, Adam Thompson will discuss the use of (and possibly demonstrate) lvm(8) snapshots, particularly their use for quick rollback. Door Prizes On top of whatever else is on offer this month, we'll have a copy of the O'Reilly book "Mind Hacks" as a door prize. Come out and have a look at it and maybe get your own copy for free!

Weird code showing up in bash history
by Kevin McGregor 30 Jan '16

30 Jan '16

Has anyone seen this happen? On several Ubuntu server systems (10.04, 14.04, 15.10), I'll be scrolling through the bash history with the up-arrow, and suddenly there will be a ton a code with the word "tideway" used in it very often. I'll check the dot-bash_history file, and sure enough there are large sections of script/code in there which I obviously did not type. Where did it come from? How do I stop it? Here's a short sample: tw_command() { cpuspeed=`egrep '^(cpu MHz|cpu clock|clock)' /proc/cpuinfo | cut -f2 -d: | sed -e 's/\.[0-9]*//' -e 's/Mhz//i' -e 's/ //g' | head -n 1`; cputype=`egrep '^cpu[^a-z]*:' /proc/cpuinfo | sort -u | cut -f2 -d: | sed -e 's/^ //' | head -n 1`; if [ "${cputype}" = "" ]; then cputype=`egrep '^model name' /proc/cpuinfo | sort -u | cut -f2 -d: | sed -e 's/^ //' | head -n 1`; fi; if [ "${cputype}" = "" ]; then cputype=`egrep '^arch' /proc/cpuinfo | sort -u | cut -f2 -d: | sed -e 's/^ //' | head -n 1`; fi; if [ "${cputype}" = "" ]; then cputype=`egrep '^(cpu model|family|vendor_id|machine|Processor)' /proc/cpuinfo | sort -u | cut -f2 -d: | sed -e 's/^ //' | head -n 1`; fi; logical=`egrep '^[pP]rocessor' /proc/cpuinfo | sort -u | wc -l`; physical=0; cores=0; threads_per_core=0; if [ "`echo $cputype | cut -c-2`" = "PA" ]; then cpufamily=`egrep '^(cpu family)' /proc/cpuinfo | sort -u | cut -f2 -d: | sed -e 's/^ //' | head -n 1`; if [ "`echo $cpufamily | cut -c-7`" = "PA-RISC" ]; then cputype="${cp(tideway_i=__TIDEWAY; echo ${tideway_i}_CMD_START__; tw_command; echo ${tideway_i}_CMD_END__) tw_command() { cpuspeed=`egrep '^(cpu MHz|cpu clock|clock)' /proc/cpuinfo | cut -f2 -d: | sed -e 's/\.[0-9]*//' -e 's/Mhz//i' -e 's/ //g' | head -n 1`; cputype=`egrep '^cpu[^a-z]*:' /proc/cpuinfo | sort -u | cut -f2 -d: | sed -e 's/^ //' | head -n 1`; if [ "${cputype}" = "" ]; then cputype=`egrep '^model name' /proc/cpuinfo | sort -u | cut -f2 -d: | sed -e 's/^ //' | head -n 1`; fi; if [ "${cputype}" = "" ]; then cputype=`egrep '^arch' /proc/cpuinfo | sort -u | cut -f2 -d: | sed -e 's/^ //' | head -n 1`; fi; if [ "${cputype}" = "" ]; then cputype=`egrep '^(cpu model|family|vendor_id|machine|Processor)' /proc/cpuinfo | sort -u | cut -f2 -d: | sed -e 's/^ //' | head -n 1`; fi; logical=`egrep '^[pP]rocessor' /proc/cpuinfo | sort -u | wc -l`; physical=0; cores=0; threads_per_core=0; if [ "`echo $cputype | cut -c-2`" = "PA" ]; then cpufamily=`egrep '^(cpu family)' /proc/cpuinfo | sort -u | cut -f2 -d: | sed -e 's/^ //' | head -n 1`; if [ "`echo $cpufamily | cut -c-7`" = "PA-RISC" ]; then cputype="${cpprintf("hostid: ");

Red Hat on Azure
by John Lange 27 Jan '16

27 Jan '16

I thought some people on this list might be interested. https://azure.microsoft.com/en-us/campaigns/redhat/ In a nutshell, you can buy your Red Hat machines as a VM directly from the Azure market place. The monthly fees include the Red Hat subscription and support as well as the VM to host the server. There are a few flavors available including a "micro" footprint server. SUSE has been available in Azure for quite some time, now Red Hat is officially available. Note that this is really intended for businesses looking for fully supported solutions. It's not really suited to hobbyists looking for inexpensive DIY. Regards, -- John Lange www.johnlange.ca

Thanks for all the input folks. I'm grateful for what looks to be a good solution all round. I'm not familiar with HostGator. The guy that I've used for many years has been great. I wouldn't be leaving if he wasn't shutting that part of his business interests down. I'll be in touch Hartmut. Thanks again. Cheers!

USB drive encryption
by Dan Martin 26 Jan '16

26 Jan '16

I need a device to transport data securely between machines - from PC to Mac or Mac to PC, or between 2 PCs. Problem is, I don't have admin rights on any of the PCs. I also don't want to leave unencrypted copies of the files on the PCs. Preferably, I would want various forms of software on PC or Mac to read and write to the drive transparently after the passphrase is entered. Will a hardware encrypted flash drive do this? or will it want to set up something on the PC requiring admin rights? Can anyone suggest a good, relatively cheap device? -Dan

Request for HELP! Solaris 11 printing (CUPS)
by Kevin McGregor 13 Jan '16

13 Jan '16

I just don't understand Unix printing, I guess. We had it working on Solaris 10 using the old standby lp printing system. Solaris 11 now uses CUPS, and I can't find a reference anywhere that is helpful. On the old/current Solaris 10 system, we have: $ lpstat -t scheduler is running no system default destination system for cowsvpprmom: 192.168.59.113 (as lpd:// 192.168.59.113/printers/GENERAL_ENTRY#Solaris) system for cowsvdprmom: 172.17.176.58 (as lpd:// 172.17.176.58/printers/GENERAL_ENTRY#Solaris) cowsvpprmom accepting requests since Fri Jan 08 12:09:10 2016 cowsvdprmom accepting requests since Fri Jan 08 12:09:10 2016 printer cowsvpprmom disabled since Fri Jan 08 12:09:11 2016. available. printer cowsvdprmom disabled since Fri Jan 08 12:09:11 2016. available. On the new Solaris 11 system (zone) I tried: # lpadmin -p cowsvdprmom -E -v lpd://cowsvdprmom/printers/GENERAL_ENTRY # lpadmin -p cowsvpprmom -E -v lpd://cowsvpprmom/printers/GENERAL_ENTRY ...which doesn't seem to work, because I couldn't print anything (the lpr command works, but then the print queue gets disabled) and this shows up in the CUPS error log: D [13/Jan/2016:11:18:20 +0600] [Job 3] Connecting to printer... D [13/Jan/2016:11:18:20 +0600] [Job 3] STATE: -connecting-to-device D [13/Jan/2016:11:18:20 +0600] [Job 3] Connected to printer...
