From the keyboard of Bjoern A. Zeeb: > i4btrc: 4 ISDN trace device(s) attached > i4bing: 4 i4b NetGraph ISDN B-channel device(s) attached > ing: ng_make_node_common, ret = 22 This is fixed in -current (which should also be applicable to 4.x). The fix was posted on the mailing list. Writing a PR would help to get this into stable! > Trying without netgraph and everything 's fine.

In /usr/src/sys/i4b/driver/i4b_ispppsubr.c (as i told you), grepping for CISCO gives as one of the first hits: #define IFF_CISCO IFF_LINK2 /* auto-dial on output */ The comment is for shure misleading, but it looks to me that setting link2 will give you the CISCO protocol. Grepping further gives: #define CISCO_MULTICAST 0x8f /* Cisco multicast address */ #define CISCO_UNICAST 0x0f /* Cisco unicast address */ #define CISCO_KEEPALIVE 0x8035 /* Cisco keepalive protocol */ #define CISCO_ADDR_REQ 0 /* Cisco address request */ #define CISCO_ADDR_REPLY 1 /* Cisco address reply */ #define CISCO_KEEPALIVE_REQ 2 /* Cisco keepalive request */ There are the keepalives. hellmuth -- Hellmuth Michaelis Tel +49 40 55 97 47-70 HCS Hanseatischer Computerservice GmbH Fax +49 40 55 97 47-77 Oldesloer Strasse 97-99 Mail hm [at] hcs.de D-22457 Hamburg WWW http://www.hcs.de To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-isdn" in the body of the message
