Hi I''ve migrated from Passenger to Unicorn about a week ago. It''s great. Great transparency and management, thanks for this great software! A few of my Rails applications start background jobs using Kernel#fork. Of course, the ActiveRecord connections are closed and reopened again in the parent and child processes. The child process also does its job. Unfortunately, it seems

Hey all! I've been using OpenSSH on Linux since version 1.2.2; great work... There is, however, a pretty noticable memory leak in ssh-agent. I use ssh-agent to provide RSA authorization to automatically open an ssh connection to download POP mail every three minutes. When I was using the standard ssh-agent from 1.2.27 (not OpenSSH), I could leave ssh-agent running for the entire uptime of

...is a bug in the - commercial and expensive - compiler. I didn't try gcc on that platform, yet. No, I didn't try 0.9.6, yet. 2. scp will hang after the file transfer(s) The "fix" is to change the line 495 in serverloop.c from shutdown(fdin, SHUT_WR); to shutdown(fdin, SHUT_RDWR); The same which I did in 2.1.1. 3. X11 forwarding does just work for standard X clients - if you configure it with --with-ipaddr-display - but not for all X applications. The reason is that Siemens is using a named pipe in /tmp/.X11-unix for X communication where every other OS uses a s...

On a non-trusted system with HP AnsiC it seems to work if changing shutdown(fdin, SHUT_WR) to shutdown(fdin, SHUT_RDWR) in serverloop.c (lines 320 & 464) On a trusted system with gcc however this does not seem to have any effect. Here I use #define USE_PIPES 1 in includes.h as workaround I think I will have to do some more checks with compilers/(non-)trusted systems... Or any other ideas? Klaus steve...

...est - see nbdkit commit 430f8141. We may want to add h->sock->ops->shutdown() (especially if we want to handle SHUT_WR through adding more states for more graceful shutdown paths, including when TLS is involved), but even in the short-term, something as simple as adding shutdown(h->fd, SHUT_RDWR) immediately before the s->sock->ops->close() would be helpful. That said, I think we want a two-pronged approach - adding a use of shutdown(), but also playing with signal: > - if (h->pid >= 0) /* XXX kill it? */ We're only doing this for connect_command. We must NOT ki...

I am running OpenSSH 2.9p1 on SunOS 5.7 w/4-24-2001 patch cluster. Like many other users I am seeing the hanging session on logout with background processes. This is a huge problem for me as I centrally manage 50+ machines with rdist across ssh. Instead of just complaining about the problem I thought I would put my CS degree to use and try to track down the problem myself. For starters,

nbdkit 1.2 as a server waits for read() to see EOF, even after the client has sent NBD_CMD_DISC. That was fixed in mbdkit 1.4; and most modern NBD servers are smarter than this (they close() the write end of their traffic soon after NBD_CMD_DISC). But it's easy enough to revert nbdkit commit c70616f8 to get back to a server with the same behavior as the older nbdkit, at which point both

Things that are still outstanding: 1) Solaris/Redhat/HPUX session.c patch. I've not seen a ya or na on Kevin's pam patch from the Solaris group. 2) Odd Redhat/Debian scp/ssh issues. .. I'm baffled, and I can't replicate the bug. Nor have I seen anything remotely like it reported. 3) SCO.. Is it happy yet for compiling? =) Completed: 1) mdoc2man.pl .. Commited into

This is a simple patch which stops nbd_close from waiting too long for a server subprocess to shut down. I wanted to send SIGHUP because the server will be able to catch it and do a clean shutdown if that is required. Is another signal better? Is it right to send a signal here? Rich.
