I'm also a fan of the RocketPort card. I am a little concerned that the first time you use it, the driver logs to dmesg: WARNING: driver rp should register devices with make_dev() (dev_t = "#rp/0x10082") Has the driver been updated since FreeBSD 4.5? (Yeah, our RocketPorts are on older machines... a testament to how reliable FreeBSD 4.x is :-) ...we haven't needed to upgrade them). My other concern is that the RocketPorts have RJ45 connectors and finding the right cable is sometimes difficult. They look like modern Cisco RJ45 serial ports, but they aren't compatible. I wish there was a vendor that I could call and say, "Hi! I have this weird device... here's my credit-card #... send me the right cable for my console server." --tal To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
