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. I assume this was an oversight, and cmsgbuf.tmp should be removed? DES -- Dag-Erling

Hi All-- First, thanks to Timo for solving my last issue. I got dovecot up and running on one of my machines, and it does exactly what I want. Now I'm trying to install dovecot on an older box (glibc 2.0.7 Linux kernel 2.0.36), and encountering some problems: -- firstly autoconf/automake does not seem to correctly deal with the madvise function on this system. It detects that we don't

Hi, I am reinstalling my server and i have encoutered a strange problem, both dovecot 2.0.13 and 1.2.16 are reporting me a problem with fd_send Invalid argument on imap login. I am running dragonfly bsd 2.10.1., compiled dovecot from pkgsrc. Can someone help me out or at least point me in some direction, i am a bit lost... :( Aug 15 10:01:00 master: Info: Dovecot v2.0.13 starting up Aug 15

Hello. I am trying to setup Dovecot on an Alpha running FreeBSD 4.10. I am simply trying the imap/pop3 protocols at this time. But with both protocols the log message I get is: pop3-login: fd_send(5) failed: Bad file descriptor dovecot: child 275 (login) returned error 89 or imap-login: fd_send(5) failed: Bad file descriptor dovecot: child 275 (login) returned error 89 I have tried

as the next klibc release 1.5.16 looks like shaping up, I have a trouble to build that for Debian. currently I build depent on linux-libc-dev, I don't know what against I can build latest klibc, see klibc fails to build due too: make -C linux/ ARCH=x86_64 INSTALL_HDR_PATH=debian/tmp/usr/lib/klibc/ headers_install make[3]: *** No rule to make target `headers_install'. Stop. make[2]: ***

The next OpenSSH release is close, too. If you want OpenSSH 3.2 to be the best version of OpenSSH, then please test the snapshots. If you like to see new features in future OpenSSH releases, then test the snapshots. If you are running OpenBSD then please test the OpenBSD snapshots. If you are running the portable OpenSSH release then please test the nightly snapshots from
