Well Greg, that probably 'sounds like' 'kind of' *a* solution. But in my humble opinion that is not *the* solution. Actually, not a solution at all. The problem is the very fact that my FBSD box *tries* to look up AAAA records before A records. My DNS server is really a bit dumb (stupid?), but that is *another* problem. > Anton, have you tried a different name server? I have just tried my ISP's name server. Well, it reduces the delays, but it does not *cure* the disease. E. g., now sendmail starts up during ~45 seconds (compared to 150 seconds before). Faster, though still veeeery slow. Thank you, Greg, thank you, Nathan KInkade for your help. I will have holidays till May 13, but then I hope I'll be able to recompile sendmail, ftp, ftpd, telnet et al (maybe even kernel?) to make them use good old IP v.4. Again, thanks everybody who participated in this thread! -- Anton To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
