I am attempting to build an i386 jail on an amd64 box to build packages for my netbook. The host is running -current from just over two weeks ago and the jail is -current from early June. The jail was built by doing a dump|restore of my netbook and then tweaking various config files to give it a new identity. The jail's devfs is using "devfsrules_jail" from /etc/default/devfs.rules. The jail starts OK but when I attempt to ssh into it, I just get "Connection closed by <jail IP address>". Adding debugging on the child, I see that it occurs immediately following: "debug1: expecting SSH2_MSG_KEX_DH_GEX_REPLY". Looking at a ktrace of the jailed sshd, the problem is inside the privilege separation child. When I turned off privilege separation, I can log into the jail. When I added a syslog socket inside the jailed chroot and left privilege separation enabled, I got: Aug 24 19:04:40 server sshd[70809]: error: buffer_put_bignum2_ret: BN too small Aug 24 19:04:40 server sshd[70809]: fatal: buffer_put_bignum2: buffer error Unfortunately, buffer_put_bignum2() is called from a number of locations so the actual problem is not clear. Looking at google doesn't turn up anything useful. Does anyone have any suggestions? -- Peter Jeremy
