Re: Help: HOWTO buy IP address blocks from ARIN?
Sure, using IPv6 for the vpn's address pool would be even better, if the vpn software supports it. The multiple vpn servers on RFC1918 blocks would be an interim Plan B if using IPv6 were not feasible for some reason. A sysadmin team's lack of knowledge and experience with IPv6 might be such a reason, if the vpn solution needs to be rolled out in the immediate future.

Actually from my upstream ISP (UUNET) many years ago. I was requesting a /21. The requirements were essentially the same back then. You're requesting 4K addresses. They want to know that 1K will be used right now and that at least 2K will be in use within a year. If the only way you can use up that number of addresses is by allocating one thousand /30's they will turn you down. They are basically looking for individual addresses, but you can count the lost addresses from your subnet scheme. I'm trying to interpret the requirements they give for an end-user initial assignment, which are: * provide data demonstrating at least a 25% utilization rate of the requested block immediately upon assignment * provide data demonstrating at least a 50% utilization rate of the requested block within one year .. and maybe I'm just being dense, but it's not entirely obvious to me what utilization rate actually means here: do they mean sub-blocks allocated to specific subnets with some-definition-of-minimal waste, or do they mean individual addresses actually, specifically assigned? I'm trying to rationalise a /20 block, because I can't seem to partition the space such that I end up with 50% allocated immediately or 75% allocated over the next year; but if I count up the actual nodes that I expect to exist on all of my subnets, those counts are definitely short of both the `25% utilization immediately' and `50% utilization within one year' figures. If I'm really supposed to be counting individual addresses and not summing subnet sizes, what am I likely to be doing wrong here? -- gnhlug-discuss mailing list gnhlug-discuss@mail.gnhlug.org http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss/ -- John Abreau / Executive Director, Boston Linux Unix Email j...@blu.org / WWW http://www.abreau.net / PGP-Key-ID 0x920063C6 PGP-Key-Fingerprint A5AD 6BE1 FEFE 8E4F 5C23 C2D0 E885 E17C 9200 63C6 ___ gnhlug-discuss mailing list gnhlug-discuss@mail.gnhlug.org http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss/
Re: Help: HOWTO buy IP address blocks from ARIN?
If I were doing it, I'd consider setting up several redundant vpn servers. RFC1918 defines three private address blocks: 10.x.x.x/8 172.16.x.x/12 192.168.x.x/16 I'd start with 3 vpn servers, each using one of these blocks. Odds are one of them would work at a given customer site. Maybe throw in a fourth one with a small pool of public addresses for the hypothetical pathological cases where the customer is using all three private address blocks. If I needed more than 3 (or 4) vpn servers, I could subdivide the 10.x and 172.16 blocks.

Just buy a block of IP addresses that are actually guaranteed routable is the solution that I've seen in place at all of my former companies, though I've never been the one to make it happen before. How would you do it?

Re: Help: HOWTO buy IP address blocks from ARIN?
You mentioned that 1k addresses go to a main-office LAN. I'd put all of your fixed infrastructure on the main-office LAN, and host the vpn servers there. Granted, using a single IPv6 block instead of multiple RFC1918 blocks would be far less of a headache to get working.

Re: Help: HOWTO buy IP address blocks from ARIN?
The way I see it, there's a preferred strategy, and a short-term strategy that should be planned with the expectation that it will be migrated to the preferred strategy in the near future. The reality is that the IPv4 address pool is effectively exhausted, and any new deployments should ideally be based on IPv6. The few remaining IPv4 blocks are essentially a rapidly-eroding safety net reserved for dire emergencies during the transition to IPv6. They're hard to get, and getting even more difficult to get as time goes on. For the short term, assuming you haven't rolled out IPv6 yet, new deployments ideally should use RFC1918 private addresses internally and NAT to map them to public addresses for connecting to the public IPv4 Internet, with the expectation of transitioning to IPv6 addresses as soon as feasible. What are your project's needs that explicitly require 4K distinct public addresses and that cannot function using private addresses and NAT instead?

Re: Local inexpensive media destruction?
Last time I had to deal with this, I had about a dozen hard drives to destroy. I dismantled them and degaussed the individual platters, then used them as coasters, brought a few home to toss into the recycle bins at my condo and at several friends' homes, etc. I'm confident that this provided enough separation in space and time to ensure it would not be feasible for nefarious types to reconstruct the data that used to be on those platters, even if any of the bits managed to survive degaussing. And while the procedure was probably far more than was really necessary, the effort was fairly minor; as I recall, it took maybe five minutes to dismantle each hard drive, and perhaps another minute or two to degauss its platters. Of course, this procedure wouldn't scale very well to the hundreds of hard drives, floppies, etc. that you must have accumulated in 15+ years.

I've done two upgrades since I installed in early January. Each time was a bit more difficult than I was expecting. Not as smooth as I'd expect from an appliance, but better than upgrading Windows. Both times I tried to upgrade within the 9.2 series, I got errors about limited disk space in /var to perform the upgrade. After rebooting and trying the upgrade again, it succeeded. Not a huge deal, but did add to the time it took to upgrade. The HP isn't the fastest booting system out there. Total time was probably half an hour. Lastly, there's plugins and jails. I haven't made much use of this yet, but probably will as I get more comfortable with it. Plugins give you access to various other applications, like owncloud, sickbeard, subsonic, crashplan, and bacula-sd. Installing a plugin puts it into its own separate jail with its own IP address and network configuration. You can then have each jail get access to specific datasets. -Mark [*] Ok, this is really odd. The only browser I have reliably working to get to set quotas is Firefox.

Re: What are you doing for home NAS?
Even if the MyBook Live turns out to be more reliable than I'd expect, that doesn't negate the poor performance of the unit, especially when it's accessed simultaneously by multiple clients. With my usage patterns, that limitation is extremely noticeable.

I think this stance is a little overly cautious; there is data showing that consumer drives don't fail at rates significantly different than server-grade drives -- e.g., http://blog.backblaze.com/2013/12/04/enterprise-drive-reliability/ (though I also remember studies done on significantly larger datasets a couple years ago, but they aren't leaping at me from Google). What I *have* found to be troublesome is that some RAID solutions don't handle drives that spin down very well. For this reason, I tend to either go with server-grade drives, or really do my homework, and find drives that work with the solution (e.g., 3Ware has -- or, at least, had -- an approved hardware list that I find useful). But I think that, with a suitable amount of caution, there's money to be saved here without loss of functionality or increased risk of data loss. $.02, -Ken P.S. One thing I should add here, just from a hoo-boy-did-I-stub-my-toe perspective: as a rule, I usually have my arrays use just a letle bit less than the whole disk. I had a large RAID-5 array once, and one of the drives failed. I got it RMA'd *with the same model number* from the manufacturer... and it was one sector smaller. THAT was annoying.

Streaming video from MIT classrooms for BLU meetings?
In the past we've had discussions about providing streaming video of BLU meetings, but none of us were sure how to go about setting it up. However, at last month's BLU meeting, someone pointed out that MIT's classrooms now have built-in cameras which should make the process feasible. I contacted MIT's Sloan School tech support about the classroom's built-in cameras, and they said we could use the self-service IP video conferencing function of the room to provide streaming video via an outside service, but they cannot provide any support for us, so we need to figure out the details on our own. Is anyone familiar with how to use their video conferencing, and what we would need to set up for the outside service? Ideally I'd like to install something on one of the BLU servers using an open-source engine that can both stream the live video and simultaneously capture it to a file that we could later edit and upload to YouTube. Here are the technical details their tech support folks provided: I'm sorry, but we can’t accomodate your request for video streaming and recording using the Sloan School’s in-house services. The reason is partly our service model, and partly technology driven. On the service side, the recording service is only available to the MITSloan community for academic uses or for events by official MIT Sloan groups. On the technical side, the camera and microphone outputs are only routed into the Sloan School’s classroom recording and video conferencing systems, so there is no way to direct the output to a laptop, or even to the in-room computers, for capture in YouTube or any other software client. You are welcome, however, to use the self-service IP video conferencing function of the room. The rooms use Cisco C-series codecs, which operate on the h.323 standard, and connect via TCP/IP. If you have access to a service that you can call and stream to using h.323 you may be able to provide a live stream to your group. This is a self-service function of the room however, and we will not be able to provide you with additional assistance. Simply select the video conferencing function and dial the IP address or FQDN using the dialer pad. -- John Abreau / Executive Director, Boston Linux Unix Email j...@blu.org / WWW http://www.abreau.net / PGP-Key-ID 0xD5C7B5D9 PGP-Key-Fingerprint 72 FB 39 4F 3C 3B D6 5B E0 C8 5A 6E F1 2C BE 99 ___ gnhlug-discuss mailing list gnhlug-discuss@mail.gnhlug.org http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss/

Speakers for IPv6?
I'd like to schedule several BLU meetings about IPv6 for next year, and I'm looking for speakers who can give the kinds of presentations I think would be useful. We had a talk last November, but it fell short of what I had hoped for. I was looking for presentations where the target audience is people who have already decided they want to migrate to IPv6, and are asking how to proceed. The talk we actually got was interesting and informative, but it didn't address the correct audience. The talk we got focused on persuading a reluctant audience that they really need to start planning to migrate to IPv6, and it didn't really offer any useful details on how to proceed. For starters, I've come up with three basic scenarios I'd like to explore: 1. A home user with 1-2 desktops, a few laptops/iPhones/Android devices, maybe a NAS or Tivo, and a Linksys wireless router that can support DD-WRT; 2. A small office with 1-2 Linux servers and maybe a dozen desktops and laptops possibly supporting a mix of Linux, Windows, and MacOS. 3. A larger enterprise with several locations in different cities; dozens of servers including Windows, Linux, BSD, Solaris, AIX, etc; desktop, laptops, smartphones, etc including a mix of Windows, MacOS, Linux, iOS, Android, etc. To keep things simple, I think it makes sense to focus on migrating from a pure IPv4 network to a dual-stack network for these scenarios. Even with this focus, I imagine it would still take several meetings to cover the basics. Can anyone recommend speakers who can give these kinds of HOWTO talks?

Re: Computer show Saturday, in Manchester
My first attempt at installing Linux was SLS in 1994. I couldn't get it to work, and when I asked around for help, someone told me that SLS was badly broken due to untested updates, and they suggested Slackware as al alternative. My first successful install was Slackware, a week after I first tried SLS. In 1995 I received a pre-prelease copy of Caldera, and I switched to that until the 1996 meeting at UNH with Linus. There, I received a copy of Redhat 2.1, and when I tried it, I discovered that Caldera was really Redhat 2.0 plus a handful of proprietary add-ons. I switched to Redhat at that point, and I've been using Redhat, Fedora, and CentOS ever since. I've tried a number of other distributions over the years, but none were sufficiently compelling to entice me to switch again.

Re: Historical origin of cron's day-of-month/weekday behavior?
I emailed Brian about it last night, and found out that he didn't have anything to do with cron, despite the Wikipedia articles that credit him with it. He pointed me to Ken Thompson and Doug McIlroy as possible authors. Ken tells me that the behavior I expected was exactly how his original cron behaved, and he speculated that the current buggy behavior, as he put it, must have been introduced later. I first ran across the problem when I was new to UNIX. and it happened on a machine running BSD 4.1. Now that I think of it, every system I've tried it on since then has probably been derived from BSD in one way or another; I expect even Paul Vixie's version was modeled on the BSD cron's behavior, as the bug is clearly documented in the man page as an expected behavior.

Historical origin of cron's day-of-month/weekday behavior?
One thing that's always annoyed me about cron is how it handles the weekday field differently from the other fields. The first four fields, minute, hour, day-of-month, and month, are logically ANDed, but the day-of-month and weekday fields are ORed. The man page describes the behavior, but does not explain the reasoning behind it: Note: The day of a command's execution can be specified by two fields -- day of month, and day of week. If both fields are restricted (ie, are not *), the command will be run when either field matches the current time. For example, ``30 4 1,15 * 5'' would cause a command to be run at 4:30 am on the 1st and 15th of each month, plus every Friday. I've looked for an explanation for this in the past, but I've never had any luck finding one. Making this a special case makes the code needlessly more complicated and fragile, and it sacrifices useful functionality; if the weekday had been ANDed like the other fields, it would be trivially easy to specify things like third Wednesday of the month. I'm unable to find or think of a use case that would make the special behavior useful, and I have to wonder why it was designed this way.

Re: Fedora NetworkManager and dhclient help request
Hi, Pete.
In your reply, you refer to
/etc/dhclient-eth0.conf:
but I see no mention in your reply of
/etc/sysconfig/network-scritps/ifcfg-eth0
I've had problems with NetworkManager in the past that I finally
resolved by editing ifcfg-eth0. The behavior I observed was that
whenever I made changes to the network settings elsewhere,
NetworkManager would quickly notice them and then silently
change them back to match what was in ifcfg-eth0.
If dhclient-eth0.conf looks correct but ifcfg-eth0 is not, then
maybe that's why it's not working.
If you haven't already done so, I suggest trying what Shawn
O'Shea suggested earlier in this thread: put a line in ifcfg-eth0
that reads
DHCP_HOSTNAME=pds-lnxt500

A comment found on Groklaw: Tragedy all round Authored by: FoxyLad on Tuesday, August 30 2011 @ 10:06 PM EDT Sorry, but I can't bring myself to celebrate. This affair is a tragedy on personal, corporate and national levels. First up, Darl (and those who connived with him) get to live happily ever after. It sticks in my craw that his father will go on believing the cute cattle-ranching story Darl told him, instead of seeing his son for the shallow grasping scoundrel he really is. Justice has not been served. And it's not just Darl. None of the perpetrators of this fraud have received any punishment. They all have their nice houses, directorships and fat retirement funds, and haven't even received a slap on the wrist for wasting so much time, energy and money. Let alone the multiple contempt of court orders, civil and criminal charges that should have been laid. So the next generation of CEOs, their officers, lawyers and media shills will go forth confident that this tactic works - they can tie their opponents up in a decade of legal knots, without any fear of sanction. Without any evidence, or even a credible case. Any business of Novell's size and smaller is now vulnerable to a larger competitor legally strangling them to death. Without any evidence, or even a credible case. In Europe, the strength of SCO's case was quickly identified and thrown out of court in a few weeks. End of story, everyone went back to productive enterprise. In the US, however, hundreds of people spent significant portions of their careers on this one case. Include all the other nuisance litigation flying around, and the chilling effect it has on small business and it adds up to a significant drain on the US economy.

IPv6 deployment?
I'd like to begin deploying IPv6 on the BLU.ORG servers. They will need to transparently handle both IPv4 and IPv6, at least until some distant future time when IPv4 goes away. I suspect both will probably have to work in parallel for a while. Has anyone else deployed IPv6 yet? Is there a decent HOWTO that shows how to deploy it for a network of CentOS servers? Eventually I'll want to deploy it at home and at work, where MacOS and Windows clients will presumably complicate the picture. I'm assuming it will be easier to get my first deployment working if I do it in a pure Linux environment. Is this a reasonable assumption?

Re: (easy) backups [HALF SOLVED]
A proper personal backup system should include both disk duplication and archives. JWZ's procedure is good for the disk duplication part, assuming you're only backing up one personal machine. It doesn't obviate the need for an archiving strategy as well. Something like rsnapshot or BackupPC is good for that. For an offsite component, one approach that might work is to pair up with a friend, where you both run shared backup servers. You back your laptop to your local server, and have it sync itself with your friend's server to store an offsite copy, and he does the same in reverse, using your server for his offsite copy.

Re: best office/home office setup - the telecommuter
I just bought a couple Thinkpads for a couple of our engineers, and one thing I ran into was a difference in supported screen resolutions. The T500 is 1680x1050, with no other options, whereas the W500 is available as either 1680x1050 or 1900x1200. My engineers explicitly asked for 1900x1200, so we went with W500's.

Re: Linux-compatible scanner with ADF
You might try a custom search on eBay for something that's normally outside your price range. For instance, a few years ago we got a Ricoh IS100e scanner at the office, and after trying it out, I created a custom search on eBay for the same model. About a year and a half later, a liquidator put one up for auction on eBay, and I got it for $95. The unit originally listed for $1,200, and the current model that's equivalent is over $3,000. The IS100e and its successors have an ADF, and they scan to a PDF file and then email the file through a designated SMTP server. It's all platform-agnostic, and works great with Linux.

I've got a server that's been giving strange errors lately. Most noticeably, when I login, I get several errors of the form -bash: [: =: unary operator expected I've traced these to files under /etc/profile.d, and on further testing I find that the offending lines are using backquotes, e.g. if [ `/usr/bin/id -u` = 0 ] ; then When I try to use backquotes on the command line on this server, I get no output. Even stranger, if I have a suspended vi job, then running something in backquotes terminates the vi process: $ vi foo ^Z [1]+ Stopped nvi foo $ echo `echo bar` [1]+ Terminated nvi foo If I do this on my other systems, I get $ echo `echo bar` bar and the vi job does not terminate. I've tried googling for these symptoms, but so far I haven't found a match. Has anyone else run across this odd behavior? What could be causing it? The server with the broken behavior is running CentOS release 5.2, and bash is bash-3.2-21.el5. -- John Abreau / Executive Director, Boston Linux Unix IM: [EMAIL PROTECTED] / [EMAIL PROTECTED] / [EMAIL PROTECTED] / [EMAIL PROTECTED] Email [EMAIL PROTECTED] / WWW http://www.abreau.net / PGP-Key-ID 0xD5C7B5D9 PGP-Key-Fingerprint 72 FB 39 4F 3C 3B D6 5B E0 C8 5A 6E F1 2C BE 99 -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean. ___ gnhlug-discuss mailing list gnhlug-discuss@mail.gnhlug.org http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss/
Re: bash weirdness
I tried the various suggestions to no effect. rpm -V bash returns nothing. A copy of the bash binary from another server exhibits the same problem. Aother thing I noticed is when I tried logging in as a different user, the problem didn't occur. The other user was locally defined, whereas my regular user account is defined in our LDAP server (IDEALX smbldap-tools). I enabled another LDAP user to be able to login to the server, and that user also exhibits the problem. Local users, including root, do not exhibit the problem. Another thing I discovered is that piping fails; it silently terminates immediately. To verify this, I ran find / | more, and it silently returned to the bash prompt with absolutely no delay. Also, getent passwd returns all passwd entries from ldap, but getent group only returns what's in /etc/group. This part happens for local users as well as LDAP users. But why that would result in bash misbehavior is something that makes no sense to me.

Re: bash weirdness
I found that the server had the wrong base defined in /etcldap.conf and /etc/openldap/ldap.conf; when i yet the server up a little over a year ago, I mistakenly included the prefix ou=People,. After I fixed that, getent group worked correctly, but the backtick and pipe behaviors are still broken. The server is 64-bit, and I just noticed that both the i386 and the x86_64 packages of openldap, nss_ldap, etc. are installed. Would that make a difference? I'll try the rpm -Va next, and see if that sheds any light.

RE: Example of ARM based linux board using initramfs and serial console
Just as a simple sanity check, I'd test it without trying to overcomplicate things. Forget the symlinks to busybox; just rename the binary to /bin/sh, or whatever name busybox uses to decide to be a shell; then modify the test kernel to run /bin/sh instead of /sbin/init. That will at least prove that the kernel can successfully boot. And from that, you can try running by hand each command that your proposed initramfs is supposed to run automatically via init. By doing that, you should be able to identify where the init process was failing. On Fri, July 11, 2008 7:59 am, Alexander Wolfson said: This is what I am doing as well. Usually there is a statically linked program in the /bin called busybox which provides big chunk of expected command line functionality. All the programms - bash, ash, ls, ping, ... are slinks to busybox (init as well) and busybox checks ARGV[0] for the name that was used to call it and acts accordingly. It still has to be part of some filesystem and this is where the problem is. I am doing something wrong creating the initramfs and linking it with the kernel or something is wrong with my busybox or this is something else that I am not even think of.

Re: moving linux installs
The way you describe it makes it sound like you had significant effort and downtime to get this to work. Was it really much less than a reinstall/reconfig would have taken? On Sat, April 19, 2008 1:26 am, Bill McGonigle said: Wow, so today was a weird day - I wound up moving three servers onto different hardware, and their configuration was complex enough and the downtime requirements were tight enough and the budget small enough that a re-install and re-configure wasn't in the mix - so it was a 'move the hard drives and go from there' exercise, one I hadn't done recently. I was fairly impressed (not in a good way) with how hard pulling drives from one machine and running them in another was. initrd needed new drivers, modprobe.conf's needed to be updated to make that happen, raid arrays no longer auto-detected, grub wasn't valid, kudzu doesn't seem to auto-detect hardware changes anymore, and other fun stuff. I still haven't completely wrapped my head around the hwconf database, so I've got a couple machines running on eth2 and eth3 with ghost eth0 and eth1's around. Especially vexing was that it seems that grub needs to be run on the final destination hardware because of the way it does BIOS probes, so preparing the disks ahead of time wasn't obviously possible. Oh, and before anybody else gets bitten, the Fedora 8 Live CD doesn't include md* RAID tools anymore (Live 7 did). :( So, at first blush, Windows and Mac OS X beat the pants off of us on linux, because the former has multiple hardware profiles and the latter just has everything built-in, making this kind of work reasonable to easy. However, I notice that things like LiveCD's do nice auto-detection at system start and don't suffer from baroque machinations to get the things I described above working. So, perhaps this problem is solved already and just not widely distributed. Has anybody here figured out how to plumb hardware autodetection into a Redhat-line distribution (or others, I could switch distros over this). Or, is there a better way that hasn't occurred to me? (And yes, PXE booting with NFS-mounted everything of a big storage server is a good solution, but doesn't fit in the small educational settings I'm thinking about here).

Re: USB drives and device names
On Fri, January 25, 2008 4:30 pm, Dan Coutu said: On Linux a USB connected hard drive appears as a SCSI device. But the naming of the device seems to 'float' based on who-knows-what criteria. So for example yesterday I saw an USB drive device change from being /dev/std to /dev/stc. Talk about unique! I've seen the letter increment before when you disconnect a drive and reconnect it (the USB connection is what I'm referring to here) but never have I seen it decrement. Is there any kind of algorithm that could be used, perhaps within a shell script, in order to reliably mount a USB drive without fail and without having to guess at the device name? You can always mount the drive based on its label. For instance, if the partition is labeled FamilyPhotos, you can mount it via sudo mkdir /mnt/temp sudo mount -L FamilyPhotos /mnt/temp Gnome already does something similar; when it automounts a usb drive, a cdrom, etc., it creates a mount point for it under /media, based on its label, and then mounts it there. It also adds an entry for it to /etc/fstab, with the attribute managed. If the filesystem on the usb drive is ext3, you can label it with the command e2label; if it's a dos vfat filesystem, you can label it with the mlabel command from the mtools package. -- John Abreau / Executive Director, Boston Linux Unix IM: [EMAIL PROTECTED] / [EMAIL PROTECTED] / [EMAIL PROTECTED] / [EMAIL PROTECTED] Email [EMAIL PROTECTED] / WWW http://www.abreau.net / PGP-Key-ID 0xD5C7B5D9 PGP-Key-Fingerprint 72 FB 39 4F 3C 3B D6 5B E0 C8 5A 6E F1 2C BE 99 -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean. ___ gnhlug-discuss mailing list gnhlug-discuss@mail.gnhlug.org http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss/
Re: OLPC Crisis: Customer Data Lost
That seems typical. My XO was waiting for me when I got home from work on Dec 21; I was surprised to see it, as I had no email notification at all at that point. I think it was about a week later that I finally got an email notification that the XO had just been shipped.

I don't have mine yet (ordered week #2 - they never sent the reminder mail they promised), but I've read frequently enough that the organization was overwhelmed and really didn't know how to do logistics. I will concede they're abysmally poor communicators. Both seem odd, given the mission and all. Even my 4-year old daughter who's getting the unit has deemed them 'rude' for not telling us anything other than the one mail right before Christmas. She tells all her friends she's getting an 'XO' and asks me where it is every other day. -Bill On Jan 24, 2008, at 16:19, Kristian Erik Hermansen wrote: -- Forwarded message -- From: Kristian Erik Hermansen [EMAIL PROTECTED] Date: Jan 24, 2008 1:05 PM Subject: OLPC Crisis: Customer Data Lost To: [EMAIL PROTECTED] I have posted some info about the situation to Linux Journal, where I am on the advisory panel... http://www.linuxjournal.com/content/olpc-crisis-customer-data-lost -- Kristian Erik Hermansen Know something about everything and everything about something. - Bill McGonigle, Owner Work: 603.448.4440 BFC Computing, LLC Home: 603.448.1668 [EMAIL PROTECTED] Cell: 603.252.2606 http://www.bfccomputing.com/Page: 603.442.1833 Blog: http://blog.bfccomputing.com/ VCard: http://bfccomputing.com/vcard/bill.vcf ___ gnhlug-discuss mailing list gnhlug-discuss@mail.gnhlug.org http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss/ -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean. -- John Abreau / Executive Director, Boston Linux Unix IM: [EMAIL PROTECTED] / [EMAIL PROTECTED] / [EMAIL PROTECTED] / [EMAIL PROTECTED] Email [EMAIL PROTECTED] / WWW http://www.abreau.net / PGP-Key-ID 0xD5C7B5D9 PGP-Key-Fingerprint 72 FB 39 4F 3C 3B D6 5B E0 C8 5A 6E F1 2C BE 99 -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean. ___ gnhlug-discuss mailing list gnhlug-discuss@mail.gnhlug.org http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss/
