Thanks for the heads up on gns3. We've been using a new version of PacketTracer for some labs at school in addition to real equipment, and it works pretty well, though it does have issues with RSA key generation and a couple other things. The instructors have been encouraging us to get our hands on real equipment to get used to different IOS versions and different equipment that has its own quirks (mostly command syntax). PacketTracer is available to Cisco students and alumni, but I'm sure one could find it as, uh... an extended trial version as well. ------------------------------------------------------------ Katherine Scrupa Network Technology CCNA student, RRC

I'm interested in two of the cisco 2500 routers, if you're willing to let two go to one person. I'll be writing my CCNA in September and won't have equipment to play with after mid-August. Unless someone will let me play with their Cisco equipment at work :) Now to find a couple old Cisco switches... ------------------------------------------------------------ Katherine Scrupa Network Technology CCNA student, RRC On Tue, Aug 3, 2010 at 4:02 PM, <roundtable-request(a)muug.mb.ca> wrote: > Send Roundtable mailing list submissions to > roundtable(a)muug.mb.ca > > To subscribe or unsubscribe via the World Wide Web, visit > http://www.muug.mb.ca/mailman/listinfo/roundtable > or, via email, send a message with subject or body 'help' to > roundtable-request(a)muug.mb.ca > > You can reach the person managing the list at > roundtable-owner(a)muug.mb.ca > > When replying, please edit your Subject line so it is more specific > than "Re: Contents of Roundtable digest..." > > > Today's Topics: > > 1.

Cleaning out less-common hardware

04 Aug '10

I'm cleaning out old hardware to make space, here's the more interesting pieces, if anyone wants them please reply or call my cell 797-1617: MicroVAX 3800 (makes a great bedside table) Digital Server 3000 (Alpha CPU-based, PSU modded to feed CPU 3.3V direct) Sparq portable 1GB-disk drive with 3 disks Backer32 (parallel port video 'modem', 4GB on VHS tape) IBM Token Ring Concentrator 3x new Fujitsu fiber cables, 61meter, 2 fibers, ST-ST connectors Laboratory tube PSU, variable 200-325V 0.1A Ribbon cable in foil wrap, approx. 50 wires, 200ft? Konika-Minolta Magicolor 330, huge colour laser printer, needs toner/work Eurologic 4-drive SCSI/SAS array with redundact PSUs, serial mgmt Eurologic Fiberchannel 7x 73GB (1 HD bad) RAID array with redundant PSUs, fans A few 2.4ghz wifi dishes, 19-24dbi I'm bringing a bunch of 300-800mhz PCs, 10mbit hubs, etc. to recycling places.

another shell thing I've forgotten...
by Adam Thompson 02 Aug '10

02 Aug '10

Inside a shell script, I want to start a persistent mysql client process and feed it commands one by one. I’d like to use a named pipe, but the only way I’ve found to do it so far is with a subshell, by putting 99% of the script inside the subshell and piping the subsell’s entire output to mysql. While this more-or-less works, it’s very much not ideal. If I use a named pipe, every time I echo something to that pipe (e.g. “echo INSERT INTO… > /tmp/mypipe”), mysql immediately exits upon reaching EOF, so only the very first command gets executed. I recall posting a way to accomplish this with psql & inetd a year or two ago, but I don’t want to use inetd – this *must* be entirely self-contained within a single shell script. Also I can’t figure out a way to tell mysql to ignore EOF on STDIN and to immediately reopen it. Anyone have any better ideas? Thanks, -Adam

shell scripting mysql commands
by Adam Thompson 02 Aug '10

02 Aug '10

Further to the previous question about shell scripting and MySQL… The script looks generally like this: ( commands; commands; commands; cat <<__EOF__ sql statements; sql statements; __EOF__ find $basedir –args | while read VARIABLE; do sed –i –e ‘s/xxx/yyy/gi’ –e ‘s/aaa/bbb/gi’ $VARIABLE cat << __EOF__ LOAD DATA INFILE ‘$VARIABLE’…; UPDATE stuff…; __EOF__ ) | mysql --user=… --password=… --host=… --database=… --batch I didn’t really think about order-of-operations until it came back to bite me in the ass. The script now has these comments in it. Note carefully the last point in the comments, if you’re ever doing anything like this. # The subshell allows us to start processing the mysql commands as soon # as they are echo(1)'d, improving parallelism dramatically. # Note that this does not cause magic to happen - commands will still # finish executing in order, so it's valid to, say, run sed(1) to pre- # process a file before echo(1)ing the LOAD DATA INFILE command to # MySQL. # In fact, due to stdio buffering issues, the MySQL commands probably # won't start executing until sometime shortly after they are sent; # execution is definitely asynchronous, so keep in mind there are two # separate process "pipelines" happening. So: # 1. each shell command may depend on previous shell commands having # executed; # 2. each MySQL statement may depend on previous MySQL statements # having executed; # 3. each MySQL statement may depend on previous *shell* commands # having executed; # 4. but each shell command ***MAY NOT*** depend on previous MySQL # statements having executed! -Adam
