Not just IMAP mail (which Outlooks has limits with anyway), but contacts, calendar -- the whole Outlook store. Right or wrong, that's what a lot of people want. Based on a cursory examination, it would appear Bynari's stuff does not. OpenExchange is kinda fuzzy on the details of their "Outlook Connection", but screen shots of Outlook are conspicuous by their absence. > My primary beef with [SuSE OpenExchange] is the cost.

The issue I usually face is that people want the kind of Outlook integration that Exchange provides, but I would like to be using a Linux server. Since nothing on Linux I know of can meet their needs, we go with Windows instead. The only product I've found that does MAPI that runs on Linux is Samsung Contact (formerly HP OpenMail), and Samsung won't talk to you unless you're buying 500 or more seats. Again, I can do things like IMAP and LDAP in Outlook, and web-based systems for the rest, right now, for free. Spending more to get the same doesn't make sense. I'm willing to spend more to get more, but I want to see that I'm actually getting more. -- Ben Scott <[EMAIL PROTECTED]> | The opinions expressed in this message are those of the author and do | | not represent the views or policy of any other person or organization. | | All information is provided without warranty of any kind. | ___ gnhlug-discuss mailing list [EMAIL PROTECTED] http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss

In fact, the system should basically think it's running from a floppy disk (emulated by the CD). I'd check BIOS settings, both in the motherboard BIOS, and in the SCSI host adapter. Check for firmware updates from the manufacturers for both, too. I'd also try using an old-fashioned floppy disk to boot the system, to see if that makes a difference. -- Ben Scott <[EMAIL PROTECTED]> | The opinions expressed in this message are those of the author and do | | not represent the views or policy of any other person or organization. | | All information is provided without warranty of any kind. | ___ gnhlug-discuss mailing list [EMAIL PROTECTED] http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss

I recently did an investigation for a client of Linux based alternatives to Exchange. I found two that were very good at providing full blown Exchange capabilities and compatibility. One was the Novell/SuSE OpenExchange product. It has come a long way over the past couple years. It now provides full support for shared calendars, shared files, etc. in addition to email. My primary beef with it is the cost. For small shops the cost, while cheaper than Exchange by 1/2 to 1/3 less, is still substantial. The OpenExchange server is a complete standalone system. In other words, when you buy it you get a full-blown SuSE Linux system with the email server in place. So you need to install it on a computer by itself. You can't just install the software on an existing system that you already have. The second, and more cost-effective, was a product sold by Bynari that is called Insight Server. It provides about the same functionality as OpenExchange for about half the price. Another nice thing is that the Bynari product can be installed on an existing system of yours that is already doing other work. It will run on multiple flavors of Linux. So it's a lot more flexible. I'd have to say that for someone who needs a true alternative to Exchange, because they plan to use Outlook with it (and maybe Evolution as well), then one of these products is the way to go. None of the FOSS programs provide all the functionality that these commercial products do. For specifics on these: In order to buy Novell OpenExchange you have to go through one of their partners. Their partner that covers New England is Systems Solutions out of New York. You can find more on their web site at: http://www.systemssolutions.com/html/softwarea.htm The Bynari product has more information at: http://www.bynari.net/index.php?id=1169 I've not yet deployed either of these and so cannot provide first-hand experience.

Correction: The connection(s) which carried the attacks originated from those servers. That is all you can say for sure. From the name, we can suppose they are caching proxy servers. A huge problem on the Internet today is that attackers relay their attacks through third-party proxy servers. It is entirely possible that the attacker is somewhere else entirely, and was using those servers for cover. Indeed, that "friend" might have just been an alternate route for the same attacker. Of course, it is equally possible that the attacker was a "legitimate user" (I use the phrase loosely) of those proxy servers. We have no way of knowing for sure without getting in touch with the operator(s) of those servers. (And maybe not even then.) This is why I don't get excited about random probes (of the type mentioned in another recent thread here). They're practically at the level of continuous background noise at this point, and they are generally nearly impossible to trace.

Of course, that doesn't help when your system is found to be not secure, as you have discovered, Greg. :-/ You have my sympathy.

It is possible that the details of your compromised server were disclosed by the attacker(s), and that information was then picked up by Google. Another possibility is web logs. Are you web logs available to anyone who happens to know the right URL? If so, it is amazing how easy it is for that information to get caught by a spider.

Last I looked (which was admittedly some time ago), OpenExchange was nothing more then an IMAP server bolted on to a glorified web calendar. While a useful product, about all it had in common with Microsoft Exchange was the word "Exchange" in the name. More importantly, you could get the same thing for free with any IMAP server and phpGroupWare. So OpenExchange always struck me as more of a marketing effort then a unique product. That's a valid business technique, of course. It works for Microsoft, after all. But, IMO, releasing OpenExchange as GPL isn't such a big deal, from a technical stand-point. I find it far more interesting that *Novell* -- the same company that used to threaten legal action for reverse-engineering their protocols and data structures -- is releasing major products under the GPL. > Also, there is a project called OpenGroupware which is GPL > http://opengroupware.org/en/users/faq/index.html Also these: - http://www.phpgroupware.org - http://www.phprojekt.com/ -- Ben Scott <[EMAIL PROTECTED]> | The opinions expressed in this message are those of the author and do | | not represent the views or policy of any other person or organization. | | All information is provided without warranty of any kind. | ___ gnhlug-discuss mailing list [EMAIL PROTECTED] http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss

The MegaRAID line presents logical drives (LDs) to the OS. It builds LDs out of physical disks (PDs). The OS doesn't know about the physical disks; it just sees one big logical unit. The controller does whatever is needed (striping/mirroring/parity/etc) to turn your PDs into LDs. The controller keeps configuration information in NVRAM and on disk. When you deleted the LD, it wrote that fact to NVRAM and disk. That means no more LD for the OS to see. In theory, if you re-create the LD with the *exact same parameters* that it had before, the contents of the LD will still be there. Things get a bit tricky, depending on the RAID level you use, the firmware rev you have, and the type of RAID array (e.g., a RAID-1 mirror member looks just like a regular disk in most respects, but a RAID-5 array will be totally scrambled). But it can work. It's not guaranteed, of course, but I have done it before. > I am certain that all that's happened is the RAID controller re-wrote a > new partition table with no partitions. Not exactly a partition table. The RAID configuration information lives "outside" the LD the OS normally sees. I think it is kept at the end of each PD, although I'm not sure on that. The OS then puts a partition table inside the LD. If the LD-recreate trick described above works, then your partition table will re-appear, along with everything else that used to be in the LD. > Can I recover from this without having to do a reinstall?

FYI: The Smart-UPS 1400 is discontinued. The similar Smart-UPS 1500
provides 120 volt out with a 120 volt, 15 amp input -- what the "regular
outlets" most people in the US are familiar with provide (NEMA 5-15).
That's the largest current Smart-UPS that uses a NEMA 5-15 input. Larger
models can still take a 120 volt input, but require 20 or 30 amp circuit
("funny outlets").

All the current Smart-UPS units provide similar communications features.
Some of the really old units have more limited functions, but unless the
unit is 8+ years old, that won't matter.

In my opinion, you can't go wrong with APC's Smart-UPS, Matrix, and Symmetra lines. They may not be the cheapest, but they always work, and well. Any Smart-UPS will work with apcupsd, NUT, and/or APC's own PowerChute tools on Linux. The current PowerChute stuff is agent only on Linux (needs Windoze for GUI), but I've still got a copy of PowerChute for X11 that works fine if that's what one whats. apcupsd works fine everywhere, of course. I haven't played with NUT much, because apcupsd did what I needed, but I understand the results are similar. > I'm sure some of you will say things depend on how I'm going to use it. > Well, initially like to buy an inexpensive one to use at home with RH8 and > get familiar with apcupsd and NUT. Well, the Smart-UPS 420 (the smallest model APC offers) lists for $180, which may or may not be too much for your budget for simple experimentation. APC's Back-UPS line also works with apcupsd, at least for the few models I've tried. The Back-UPS line only supports "simple signaling" -- basically, an indication that the UPS is running on battery. The Smart-UPS and fancier lines support "smart signaling", which provide two-communication and data reporting (temperature, voltage, etc.). -- Ben Scott <[EMAIL PROTECTED]> | The opinions expressed in this message are those of the author and do | | not represent the views or policy of any other person or organization. | | All information is provided without warranty of any kind. | ___ gnhlug-discuss mailing list [EMAIL PROTECTED] http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss

Re: UPS recommendations wanted
Hi Tom, Thanks for the response. I've had good success with APC. Could you tell me which model(s) you've used with Linux? I would recommend against the Belkin Universal UPS series. > NUT doesn't have drivers for it (unless they've added it in the last 3 months). They appear to support it now according to the compatibility list for the latest stable release, 2.0.0 on March 23, 2004. Or at least they support two models, F6C800-UNV and F6C120-UNV, of that series. Since you're looking at NUT, why not follow their recommendations? I guess I'm just paranoid it might not work. They seem to list some models but not others. I would just feel better buying a model that I know someone has successfuly used.

In a business situation I've also wanted environmental monitoring (voltage, temp, humidity) and paging/email when events happen. Mostly I'm concerned with a graceful shutdown when the power goes out. I've had good success with APC. I've used the APC software on Linux & Solaris. I've used apcupsd on OpenBSD. NUT doesn't like APC as much because they've had to reverse engineer everything. I would recommend against the Belkin Universal UPS series. I have one that worked well with their software on solaris. Their linux software can't seem to communicate with the UPS over the serial port. NUT doesn't have drivers for it (unless they've added it in the last 3 months).

For Sale: New Epson Stylus Photo R300M printer
Hi, Right after Christmas we had a big discussion about printers, and about that time my loyal, six-year old Cannon gave out on me. I decided to buy an Epson Photo printer because: o it could print to printable CDs and DVDs o it seemed to be supported by Linux o it had the capability of printing off picture CDs filled with photos even when not attached to a computer. You simply plug in a USB-based CD drive to the printer o it could print directly from a wide range of memory cards, including the new xD ones that fit in my Olympus o it had a little monitor that allowed you to crop, chose pictures, etc. http://www.epson.com/cgi-bin/Store/consumer/consDetail.jsp?BV_UseBVCookie=yes&oid=37472318o http://www.epson.com/cgi-bin/Store/support/supDetail.jsp?BV_UseBVCookie=yes&oid=26323&infoType=Overview I was ordering it right after Christmas so all of the local stores were out, PC Connection was out of stock, etc. So I ordered it from CDW, who told me that it was in stock. Wrong. Then they told me that it would be in "soon". I waited two weeks, had to go on a trip. "It will be in when you get back". Two weeks later, nada. So I canceled the order. I went down to CompUSA and bought one, hooked it up and it worked great. I even have it working through a D-LINK wireless printserver so I can access it from any place in my house with my notebook. No wires. Cool. Then a week later the CDW unit shows up. I call them up, give them heck, and get an NRA sent to me. I go on another trip. When I get back I find out that the NRA has expired, and I would have to get another one. I give up. So now I have this Epson Stylus Photo R300M printer, still in its unopened box, in my garage. I look on the Epson site and they have it marked at $229., which is what I paid. I will let it go for $175., but you have to come pick it up. I live in Amherst, NH. Right out of the box it works great with SuSE 9.1, although you have to tell CUPS that it is a 915 for some reason, but that is mentioned in the CUPS documentation. With standard settings it prints a little light from Linux, but I like that since it saves ink. I assume that by playing with the CUPs settings that you can get it to print darker. Printing from the memory cards with glossy paper, the pictures are just stellar. I might add that I have had no problems with the ink stopping up even though I only print about two or three pages at a time and I am often gone for a week or two between print sessions. md -- Jon "maddog" Hall Executive Director Linux International(R) email: [EMAIL PROTECTED] 80 Amherst St. Voice: +1.603.672.4557 Amherst, N.H. 03031-3032 U.S.A.

They are appropriate actions, but the tedious nature of manually adding the offending IP addresses seems too much. Check out PortSentry. It will automatically block people trying to connect to closed ports (see next comment). > 2) is there any easier way to do it? Change the port that SSH runs on. This small layer of obscurity will eliminate about 90% of script kiddies, since most of the scripts run off of a basic services type file. This will also cause anyone hitting port 22 to trip portsentry and they will be dropped. Another nice feature is that if they run a port scan against you, they will get dropped before they find the port that ssh is running on.

Can you exclude all addresses except certain one's? This is how I deal with it. Or look at port knocking for opening an ssh connection.

UPS recommendations wanted
I've looked at the UPS HOWTO and the hardware support lists for apcupsd and NUT, but I'm little uncomfortable buying a UPS without knowing others have had success using it with Linux. Is anyone willing to comment on their experiences with specific UPSes with Linux? I'm sure some of you will say things depend on how I'm going to use it. Well, initially like to buy an inexpensive one to use at home with RH8 and get familiar with apcupsd and NUT. Eventually, I'd like to install one in my wife's small office which has a RH8 Samba server and two Win98 desktops.

I would say yes. This is definitely appropriate. 2) is there any easier way to do it? Normally, I tell people to install Portsentry, which will make the blocking automatic if you are portscanned, but as this script is checking ports you have open, it won't be useful here. You might try installing it any way. I've been VERY happy with the added security it affords me, even if the list of blocked IP's is now several KB. 3) is there something else I ought to be doing? Not unless you can close off these services. Someone else may have more ideas, but it sounds like you are doing just what you should be doing.
