Which is a ridiculous restriction that causes lpd to fall flat on its face when used with 50+ printers and several hundred clients. (But as someone else noted, the test was in fact backwards and *rejected* reserved ports, so it should be at minimum fixed and at best removed or made configurable.) -- brandon s. allbery [os/2][linux][solaris][japh] allbery@kf8nh.apk.net system administrator [WAY too many hats] allbery@ece.cmu.edu electrical and computer engineering KF8NH carnegie mellon university ["better check the oblivious first" -ke6sls] To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-security" in the body of the message
