Hallo, I have a extraordinary problem with one server - all other (and I have a lot) works fine. The problem best seen in log-file: Mar 18 10:29:21 acadfs1 sshd[26793]: debug1: Forked child 26875. Mar 18 10:29:21 acadfs1 sshd[26793]: debug3: send_rexec_state: entering fd = 9 config len 675 Mar 18 10:29:21 acadfs1 sshd[26793]: debug3: ssh_msg_send: type 0 Mar 18 10:29:21 acadfs1 sshd[26793]: debug3: send_rexec_state: done Mar 18 10:29:21 acadfs1 sshd[26875]: debug1: rexec start in 6 out 6 newsock 6 pipe 8 sock 9 Mar 18 10:29:21 acadfs1 sshd[26875]: debug1: inetd sockets after dupping: 3, 3 Mar 18 10:29:26 acadfs1 sshd[26875]: Connection from A.B.C.D port 44376 # A.B.C.D is in verity a real IP Mar 18 10:29:26 acadfs1 sshd[26875]: debug1: Client protocol version 2.0; client software version OpenSSH_5.1p1 Debian-5 The sshd was forked at 10:29:21 but connection bind at 10:29:26. On client-side the break is before line debug1: Remote protocol version 2.0, remote software version OpenSSH_5.1p1 Debian-5 At first I meant, that is a question of reverse lookup, but isn't it. tcpdump show that many other trafic passed on netcard in this 5 seconds. Other protocolls (smb, https, http,...) connect in milliseconds. After esatblish the ssh-connection the transfer ist fast very well (100 MB in 32 seconds). Connections to localhost haven't a break.
