Also i contacted the german distributor for the Cyclades product line because i heard some good things about the product line. I was told, that the FreeBSD driver does not work good, but someone in Germany hacked a good running version - i could not locate him. I scanned the mail archives The cyclades driver in -current works. I have never tried cyb as it could not find out under what license it was distributed. It works better than sio, it doesn't loose uarts after panics, and there is no apparent buffer overflows (though these can be worked around with a simple patch). We are getting 1-2 panics per week for modem servers and practically none for leased line routers. Modem servers have nfs mounts, 32 ports per machine and more OSPF traffic so I don't know whether panics can be attributed to cy driver or something else. For leased line routers FreeBSD seems to be stable enough. We currently have 3 32-port configurations (modems) or one 32 port one) and 3 16-port configurations (leased lines). for Cyclades and saw that there was some flameing going on about the cy driver and that someone else had written a driver which works but which needs mgetty. I don't like needing mgetty. Nothing against mgetty, but i want to get along with getty if i want. Other than this, the Cycaldes product looked very promising, but without a working driver ... The -current driver did not work with mgetty some time ago, but I think there already was a fix for that. mgetty would be useful as it can actively reply calls instead of modems answering automatically, thus avoiding callers getting modem answer when the terminal server has crashed and won't be there. -- Heikki Suonsivu, T{ysikuu 10 C 83/02210 Espoo/FINLAND, hsu@clinet.fi work +358-0-4375209 fax -4555276 home -8031121
