FWIW, after patching the mmap issue, openssh still doesn't work on linux kernel 2.0.39 (+ patches): sshd[22202]: fatal: mm_receive_fd: expected type 1 got 2355841 I didn't dig deeper into it yet, but I believe 2.0 kernel does not support the kind of recvmsg() use privsep expects. -- v -- v at iki.fi

...m. First I was not able to compile it at all, but then I added the following line to monitor_fdpass.c #define SCM_RIGHTS 0x01 Then it compiled fine, but I am not able to log in. After having entered the password I get the following message in the logfile: Jun 25 20:25:46 raq2 sshd[16129]: fatal: mm_receive_fd: expected type 1 got 269726544 Can anybody guess what that means or has somebody got openssh running on such an old system on similar hardware? Compression is turned off. Are there any configuration options I should try?

Hi, OpenSSH 5.1 is almost ready for release, so we would appreciate testing on as many platforms and systems as possible. This release is one of the biggest in recent years, with two hackathons' worth of improvements and fixes for some of our most recalcitrant bugs. Snapshot releases for portable OpenSSH are available from http://www.mindrot.org/openssh_snap/ The OpenBSD version is

Has anyone got privsep to work under SCO Openserver? I am testing openssh3.3p1. I have Compression turned off in sshd_config. Here is the error messages that I am getting. sshd[21469]: fatal: mm_send_fd: sendmsg(3): Bad file number sshd[21476]: fatal: mm_receive_fd: recvmsg: expected received 1 got 0 --Sam

...for openssh-3.7.1p2 (Help!) Downloads for openssh-3.7.1p2 (Help!) I am using /usr/local/sbin/sshd -d -d -d to get the debugging info. I get the following error after sshd accepts my password during ssh session. This error happens when I use both putty and gnu ssh from my PC to the HPUX box. mm_receive_fd: expected type 1 got 2138968328 This is a fatal and everything shuts down.

Contrast http://cvsweb.mindrot.org/index.cgi/openssh/monitor_fdpass.c?r1=1.23;r2=1.24 with http://www.openbsd.org/cgi-bin/cvsweb/src/usr.bin/ssh/monitor_fdpass.c.diff?r1=1.14&r2=1.15 The original replaces cmsgbuf.tmp with cmsgbuf.buf, while the -portable version *adds* cmsgbuf.buf but retains cmsgbuf.tmp.

...ing -O2 to using -O on their ARM port, I found that sshd stopped working. (gcc version 4.2.1 20070719 [FreeBSD]) I have downloaded openssh-SNAP-20080220.tar.gz and the code still look the same. Anyway looking into it, I found that the problem is in monitor_fdpass.c in the functions mm_send_fd and mm_receive_fd. Using -O2 used to align the tmp array on a 4 byte boundary and using -O does not. On architectures that do not like unaligned accesses this will break. An extraction of mm_send_fd() look something like this: ############################## struct msghdr msg; char tmp[CMSG_SPACE(sizeof(int))]; str...
