Of all the gin joints in all the towns in all the world, Hostas Red had to walk into mine and say: > Hi! > > On 17 Sep 1998, Dag-Erling [iso-8859-1] Coïdan[iso-8859-1] Smørgrav > wrote: > > > Hostas Red <kong@kong.spb.ru> writes: > > > kong@kong:~> ping www.freebsd.org > > > PING freefall.freebsd.org (204.216.27.21): 56 data bytes > > > ping: sendto: No buffer space available > > > [...] > > > When i use > > > ifconfig xl0 down > > > > This shouldn't be necessary. > > > > If you type 'ifconfig xl0' at this point, is the OACTIVE flag set? > > Yes.

So far I've found about four messages related to this, which all of the following things in common: - The subject line doesn't even mention the xl driver, which means it was only by pure chance that I happen to find this thread in my mail backlog. - Nobody has mentioned what version of the xl drive they are using. For all I know you downloaded an old version from www.freebsd.org and are complaining about bugs that are already fixed. Run, don't walk, to /sys/pci/if_xl.c and show me the RCS $Id$ string so I have some idea what's going on here. - Nobody has bothered to describe the hardware they're using. What kind of CPU do you have? What other PCI devices do you have? - Nobody has told me EXACTLY WHAT 3COM CARD THEY HAVE! Is it a 3c905-TX? 3c900? 3c905B? 3c980? - Nobody has bothered to show a dmesg output with the probe information from the xl driver. - Nobody has said exactly what version of FreeBSD they're running (yes, I know this is the -current mailing list; that doesn't guarantee that people are actually running the latest and greatest -current). - Nobody has said what kind of network they're using. (10Mbps? 100Mbps? full duplex? half duplex? switched? shared? 10baseT? 10base2?) Now, I have gotten mail from many other people who report no problems whatsoever with the xl driver, and I havent had problems with my own 3c905B hardware in a long time, so I'm highly inclined to blame people for pilot error, particularly when presented with such meager details. This is really starting to annoy me. Everybody just assumes they can say "I'm having a problem, please fix it" and I can just read tea leaves or something and instantly divine the exact nature of their problems without even the slightest amount assistance. Well it doesn't work that way: I'm not a mind reader. DO NOT just say you have a problem and leave it at that, expecting somebody else to pry the details out of you later. Provide all the details up front or don't even bother posting. -Bill -- ============================================================================= -Bill Paul (212) 854-6020 | System Manager, Master of Unix-Fu Work: wpaul@ctr.columbia.edu | Center for Telecommunications Research Home: wpaul@skynet.ctr.columbia.edu | Columbia University, New York City ============================================================================= "It is not I who am crazy; it is I who am mad!" - Ren Hoek, "Space Madness" ============================================================================= To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
