How FreeBSD Handles a DNS that is Down
This is an extremely novice question on my part, but after what I recently witnessed, I am not so sure I understand all I know. The normal procedure on internet-connected systems is to set the resolv.conf file to include at least 2 domain name servers. Example: nameserver 139.78.100.1 nameserver 139.78.200.1 Last night, I had to take down our primary DNS for maintenance and lots of systems began having trouble of various kinds. While I expected the FreeBSD system I was on to hang for a couple of seconds and then start using the second DNS, it basically froze while some Linux boxes also began exhibiting similar behavior. I finally manually changed the resolv.conf on the system I was using to force the slave DNS to be first in the list and that helped, but loosing the primary DNS was not the slight slowdown one might expect. It was a full-blown outage. Are we missing some other configuration directive for Unix systems that would make the systems use the redundancy a little more gracefully than what happened? Otherwise, why have it if somebody has to manually intervene? The only thing we should have lost was dynamic updates. The systems that I know that were basically hosed were FreeBSD and Linux. As soon as the mother ship came back on line, everything was sweetness and light. Thanks for any thoughts on this issue. I have only been running DNS for around 18 years and we fortunately do not get to see this condition often and when we do, it's hopefully for very short periods, but the disruption is total.

freeradius snmp support
Hi, I have read in this mailing list that snmp support of freeradius (radiusd) has some issues and it was removed. What is the current (as of 2.1.10) status of snmp support in radiusd? Regards. PS: I may have fully misunderstood this issue because it had been really very long time.

I suspect one of them may be equivalent to empty electrically, however this way is less errorprone, explicitly populating each slot, rather than relying upon empty, which could in fact be a mistaken omission.

First remove the U3 crap from them and then they should work well :) Now, the USB keyboard protocol...ugh, they really dropped the ball on that one. It's standardized, which is good, but it's a polling interface and tends to occasionally lose events under high CPU load, which is bad. Especially if it's a key-up event that gets lost. USB mice suffer from the same problem - the polling. In the past, I never had problems with interrupt-driven (serial and PS/2) equipment, even on lowest-end (!) hardware. Today, some load can render the system nearly inresponsive for several seconds (no keyboard input, mouse stopped). This is true. I had some problems making a usb mouse work, but I had to manually plug it in to different usb slots till it worked from the start.

The keyboard(usb) sometimes takes a while longer to respond than the PS2 one, but as long as I can get some work done. Yes - an observation I had starting with FreeBSD 7 (still on my home desktop): The keyboard is sometimes detected during boot, and sometimes some time AFTER the login prompt is presented (which implies that I cannot log in to the system as the keyboard is logically not present); and in some few cases, I need to re-plugin the keyboard. The strange thing: I didn't have that behaviour on FreeBSD 5 (my home system until crash). It might have something to do with the work done at the USB subsystem. On FreeBSD 5, the mouse and keyboard resulted in this message: % dmesg | grep ^u[km] ums0: Sun Microsystems Type 6 USB mouse, rev 1.00/1.02, addr 2, iclass 3/1 ums0: 3 buttons ukbd0: Sun Microsystems Type 6 USB keyboard, rev 1.00/1.02, addr 3, iclass 3/1 Since I moved to FreeBSD 7 (didn't use 6 at home), I just get this - on the SAME system: % dmesg | grep ^u[km] ums0: vendor 0x0430 product 0x0100, class 0/0, rev 1.00/1.02, addr 2 on uhub1 ums0: 3 buttons. ukbd0: vendor 0x0430 product 0x0005, class 0/0, rev 1.00/1.02, addr 3 on uhub1 Still everything works as before.

Is there such a thing as a USB extender cable, say, a meter or two long? Sure. My SmartCard token is plugged into one on my desk. Not knowing where you are I an only suggest Radio Shack or, if there is one near you, Frys. You can easily order one on-line for a LARGE number of vendors. Just remember that the maximum length of 5 meters. I see prices for brand-name cables at about $8. Oustanding; thanks for the datapoint. There is a Frys a few miles from me, but I usually buy online. Five meters ... hm, that would almost reach to the kitchen table:-) I've seen recommendations of not exceeding 2m for USB 2.0, for video cams anyway, so suggest using a cable only as long as you need. My wife and daughter bought some of the memsticks last spring to bup a DOS/Win and for daughter's MacBook: xfer files to and from school. Since it's a lot cheaper than buying an optical drive, the flash memory is the way to go. I recall paying nearly AU$100 for my first 1GB stick some years ago, but recently picked up two 'Kingston DataTraveller G2' brand 8GB sticks (on sale, superceded model) for $30 each. There are reports of troubles - eg for booting FreeBSD - with some of the cheaper no-name brands, and for example Soekris recommend only SanDisk flash, so don't scrimp. If only using it to boot/install/fixit FreeBSD, there's currently no point buying larger than a 1GB stick; any more will be wasted, as so far sysinstall can only use 'dangerously dedicated' sticks (da0a rather than da0sXa), presumably because it detects sliced da devices as 'real' SCSI disks, but I'm really hoping to work around that someday, somehow :) I want to be able to boot from a properly sliced stick with a normal boot0 menu to be able to install or run fixit for eg 8.1-R (amd64 or i386) of a full -RELEASE a la DVD with packages, a small R/W slice for saving dmesg output etc of a tested machine _and_ a small DOS-formatted slice (s1) to exchange stuff with windows/mac users, on the one stick. But the latter is probably better another topic, for another time .. cheers, Ian ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org
