maximum segment size <networking> (MSS) The maximum amount of {TCP} data that a {node} can send in one {segment}. This should be the size of the receiver's reassembly buffer to try to avoid {fragmentation}. The equivalent at the {physical layer} is "{Maximum Transmission Unit}". (1998-03-06) (thx dict) advmss allows you to change the advertised MSS that your host offers to the peer. TCP has all kinds of weird options like this. > > But there are unfortunately many networks that don't play nice > > with this. > > Interesting. An example, and why? Sorry, I'm in ultra-inquisitive mode. Well, it relies on a packet with a Don't Fragment bit set having an ICMP packet returned by some router or the destination along the route. NAT often breaks this, and many people just block outbound/inbound ICMP. IDSen don't like PMTU generally, because it involves several "large" ICMP packets, that often get flagged as DoS attempts. (Why is ftp.sunet.se DoSing me?!) Some load balancers (I forget the brand) send out dummy packets on port 53 (dns) to assess the round trip time to a client so it can determine a server most topologically close to the client. IDSen don't like this either. :) > PS. Anyone fancy GIVING me £3000 so I can go back to university? Anyone? > Anyone? oh. Oh well! hehe, <aol sed=s,back ,,> me too! </aol>

desired effects to be achieved. From this point of view, PostScript is good and PDF is better. Both have long-established publically available standards, and all sorts of software can generate good instances of them, and I am not aware of any real limitation on producing either good PS or good PDF, using Free Software, which may be related to Adobe's proprietary stance. In my view, exactly the same principles apply to viewers etc. If someone writes a good PDF viewer which renders the GPL-generated PDF I and others produce as well as Reader does, that's fine. But so long as the existing GPL'd viewers don't, that's too bad and I will patiently wait till the skilled developers of these things get it right. Meanwhile, I'll be using Reader. BTW, this situation is not unique to PDF and Reader. The same applies, more subtly, to PS. Ghostscript is a case in point: its fonts are not Adobe fonts, and differ subtly. My printer (Brother HL-1070) is a "PostScript" printer (in that I can send it raw PS and get a good printout); but in fact it uses "BrotherScript" which is a PostScript emulation and in particular the fonts, again, are subtly different (to the extent that I have to tweak certin things in my software to get some characters to print where I want them to); and this is so that Brother don't have to pay Adobe a royalty for using true Adobe fonts. However, if I had to produce camera-ready copy for a publisher, who insisted (for design reasons) on particular proprietary fonts, then I'd pay for those fonts. And hope that the results (generated by GPL'd software) would be sufficiently impressive to scoop yet another handful of earth from beneath that wall! All the best, Ted. [1] "Patience, fleas.

files generated from within some Windows software app (?Word), and I wouldn't trust that ... even less than I'd trust Word's HTML. What would be the best way to get it to me? I don't mind receiving mail with big attachments; or if you can put it in an accessible ftp site ...? NOTE to people knocking PDF: When it's good PDF it's a great "lingua franca" for document exchange (though uneditable without Adobe Acrobat [unless someone knows better]; you can try a text editor on simple PDF files if you know what you're doing, but it's _very_ dodgy, much worse than editing raw PostScript). You would understand what I mean if you've ever sent a Windows user a PostScript file. Almost all will end up opening it in Word (usually in "fast save" mode) which will corrupt the file for ever; or printing it out as a text file (so you get the PS code instead of the rendering). On the other hand, for anyone who has installed Acrobat Reader (as many have), Windows will automatically do the right thing.

from a Windows partition (à la 'loadlin' I suppose), so no-one would be forced out of Windows by this. Will AOL configure their service so as to lock out existing subscribers who don't start using AOLinux? I doubt it! Most of the 10^7 AOLlers are using IE in Win, and used to it, and most of these wouldn't welcome being kicked off. AOL won't want to alienate them. And, for the same reason, probably not many voluntary takers in the 10^7 either. Maybe a proportion will give it a whirl out of curiosity. But, because the Web will still be what it was, they will encounter all the standard problems of non-IE users. So most of these adventurous types would revert anyway. Therefore it looks as though the potential for take-up would lie in new subscribers. Guesses at how many of these might go along (unless the free CD forced them to -- but see above) must be vaguer; but I'm not optimistic. Nor will AOL get even 10^6 new subscribers overnight. So I can't see this having much more impact than a soft thump in the middle distance. The other contra is related to the quoted comment above. If you want to try to force Web providers away from IE-inspired web coding in this kind of way, you don't need Linux at all: since AOL already have Netscape, provided this can be fixed so that it doesn't do its freeze/crash thing, they already have a tool which (if the underlying premiss has anything in it) could force the move; you can run this under Windows anyway. But users will still have IE in their Win istallations, so, when even the most standards-compliant and bug-free Netscape still trips over non-compliant web sites, they wolud tend to drop Netscape [there's an assumption here that IE works on sites where Netscape works ... ]. Where in the end, therefore, is the force which will make Web providers change their ways? So I'm finding it difficult to imagine a plausible scenario for this story. Interesting and provocative, though. Best wishes to all, Ted. -------------------------------------------------------------------- E-Mail: (Ted Harding) <Ted.Harding(a)nessie.mcc.ac.uk> Fax-to-email: +44 (0)870 167 1972 Date: 20-Jan-02 Time: 12:09:43 ------------------------------ XFMail ------------------------------

and he is using the nvidia binary modules. All bets are off. Remember, those modules causing crashes are one of the main reasons that we know have modules declaring their licence when the kernel loads them and warnings being generated for non-GPL ones. They are probably written terribly internally, but there is no way of knowing. Avoid, avoid. -- MJR

On x86 - You press the key combo 'ALT-SysRq-<command key>'. Note - Some keyboards may not have a key labeled 'SysRq'. The 'SysRq' key is also known as the 'Print Screen' key. * What are the 'command' keys? ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 'r' - Turns off keyboard raw mode and sets it to XLATE. 'k' - Secure Access Key (SAK) Kills all programs on the current virtual console. NOTE: See important comments below in SAK section. 'b' - Will immediately reboot the system without syncing or unmounting your disks. 'o' - Will shut your system off (if configured and supported). 's' - Will attempt to sync all mounted filesystems. 'u' - Will attempt to remount all mounted filesystems read-only. 'p' - Will dump the current registers and flags to your console. 't' - Will dump a list of current tasks and their information to your console. 'm' - Will dump current memory info to your console. '0'-'9' - Sets the console log level, controlling which kernel messages will be printed to your console. ('0', for example would make it so that only emergency messages like PANICs or OOPSes would make it to your console.) 'e' - Send a SIGTERM to all processes, except for init. 'i' - Send a SIGKILL to all processes, except for init. 'l' - Send a SIGKILL to all processes, INCLUDING init. (Your system will be non-functional after this.) 'h' - Will display help ( actually any other key than those listed above will display help. but 'h' is easy to remember :-) On Mon, Nov 05, 2001 at 09:10:56AM +0000, Jenny_Hopkins(a)toby-churchill.com wrote: > This lovely message was waiting to greet me on all consoles of my debian > box when i came in to work this morning, and I can't telnet in. > A search on google says: > >Upgrade to 2.2.19 , that should fix the problem.

Newmarket (after the Tuddenham junction), follow road for about 5 miles, at lights bear left into Newmarket. At next roundabout (Clocktower on it) turn left, follow road, turn left at "T" junction (Pub on left) and follow road for about 2 miles.... On entering Cheveley, take first right up "High Street", carry on past church on left. Immediately after phone box on right, go through the gates, down to the bottom of the drive BIG HOUSE... Someone will be around to point you in the right direction.. I think that about does it, power points.. There should be plenty available.... Tables, in process of sorting out, Tea and coffee... Sorted (small donation to my mum for providing would be nice though).... Apart from that...

If any more information is needed please give me a shout... If better directions are required... errrr I'll see what I can do, post code is CB8 9DG .....And the place is called Fittocks House (not Fittocks Stud)....
