Re: SLES cron environment

This seems to work fine, with one wrinkle -

On one cluster, it seems to cause sdiff to produce a compare difference,
when there is none.  At least none apparent, as the md5 results appear
identical.

Basically, there are two files, each of which contains a directory listing
of files, with an md5 sum appended to each line.  One is static, (recreated
manually, as required) with the other is dynamic, created by script called
from cron.  sdiff is also in this same script, run by cron.

If I comment out the additions to cron, things work as expected.  Again, it
is only one cluster.  Others that were upgraded to OES2 do not exhibit this
problem.

Suggestions?

NCS "heartbeat" packets

Recenlty, some windows oriented technical types have begun harping on the
"excessive traffic" rrelated to NCS.

At first, this seemed like plain old b4ll busting, but having been repeated,
several times, most recently at a official staff meeting, along with
(verbal) reports of packet sniffs ("OMG!!! 10 packets per second!!!!"), I
being to wonder.

A tempest in a teapot, not by any stretch impacting network operations, but
one that requires a response.   When time permits, I will do a few packet
captures of my own, as IIRC, there is "a lot" of useless traffic that can be
complained about.

But, thought I would put out a feeler for "known offenders" or pet peeves,
in that area.

RE: NCS "heartbeat" packets

Wow. Hardly the disaster we had with NT 4 workstations (all 4 frame types on IPX, TCP/IP, NetBEUI all on by
default) spewing SAP packets advertising every stinking workstation! Then there's the browser
elections... . I did some work at Attachmate in those days where they had broadcast storms of 3,000
packets/s! Naturally the 10 Mbit Ethernet segments were almost useless.

Ask them what the impact of those 10 packets/s is. Ask what the bandwidth used is, what the zone of impact is
(what devices/networks see the traffic). Insist on a public answer. If they refuse point out that these
are minimum size broadcast packets limited to that subnet. IOW, we are talking about 640 bytes/s on what
should be a gigabit link. In other words 0.000064% of available bandwidth. They may THINK they are
technical, but the colossal ignorance in concentrating on this fraction of traffic shows them to be
little more than script kiddies who got ahold of a sniffer.

Now if you really want to see an ugly traffic trace opening a network drive. You'll be shocked at the level and
triviality - opening every stinking file to see what's inside. EVERY. TIME. YOU. OPEN. A. SHARE.

Heh, heh, heh . . . .  This could turn out to be fun.   I kinda forgot about

It should be fun. If not drop a line and I'll help write the report. (grin)

Re: Backup for NetWare 6.5 - options needed

Yeah, I talked  to SEP, and they don't support backing up NetWare to a Windows
box unless we put in a Linux box as an intermediary, which isn't very practical
for an office of 5 people.
 
Any other backup ideas? Anyone have an old copy of Backup Exec lying around
unused? <g>

I have a customer who just upgraded their server hardware. They required 3TB of
drive space, but I wasn't able to find a reasonably-priced tape drive that would
store that much. After many conversations with them, they purchased a USB-based
removable hard drive type of system, expecting it would work with their existing
BackupExec. It doesn't. I can't find any NetWare drivers for this thing, so I'm

Re: Backup for NetWare 6.5 - options needed

Alan,
     We've never used them but after a few searches I ran across a 
company called ARKEIA that claim they support Netware. Here's a link to 
them:

Hope that helps.

If there are any questions or problems
please contact me.

Re: Backup for NetWare 6.5 - options needed

I thought BE did "to disk" backups, for several later versions?  If so, it
should be possible to mount
a USB device on NW and backup to it.   Could be wrong.

Could also just use nbackup, dsback and trustee (something) to backup
everything you need and
use the USB as a target.  Makes it more labor intensive, for restores, but
should work.

Re: Backup for NetWare 6.5 - options needed

Joe,

Yes, BE does "to disk" backups, but NetWare doesn't have any USB drivers for the infernal server. Plus, this
way they can do the backup right at their desktop and not have to go into the vault where the server is located.
