Hello, ? I need to make many (>50) ssh connections from linux to cygwin at the same time. Using Windows 2000 Server (OpenSSH_4.3p2, OpenSSL 0.9.8b and updated cygwin) and Linux RHEL4 (OpenSSH_3.9p1, OpenSSL 0.9.7a). ? It's been difficult to optimize many simultaneous connections. Here were some issues: 1.?????? On Windows XP/Professional, Microsoft intentionally cripples the TCP/IP stack.

Hi, Besides file-max and file-nr is there anywhere else I should be looking to solve a C program giving me 'too many open files' problem? (centos 3.4) While the program is complaining here were the values file-max 209632 file-nr 3655 258 209632 lsof | wc -l around 7000 during and about 1111 less after I closed the application. Any ideas? thx

Francis, I read in the list archives back that a future EventMachine release will support epoll on Linux (i.e., it''s in the trunk). Better still, is there a possibility that EM will rely on libevent so that it will be architecture independent (i.e. epoll on Linux, kqueue on FreeBSD/Mac OS X, /dev/poll on Solaris)? This is how memcached is implemented, and it would be helpful to be able

I''ve been trying to get up a rails app on some other web host that isn''t as cool as say textdrive.com or planetargon.com with their rails support. I do have acccess to dev tools, and have managed to build and install Ruby 1.8.2, RubyGems, and Rails, all under ~/bin. I''m a bit stuck on the next steps to take to try and get something running. I have access to

Hi, I work for a small company that makes radar systems for research organisations and we use FreeBSD on the PCs for data acquisition and processing. We have recently shifted to FreeBSD6/amd64 and one machine in particular is exhibiting a strange problem. The acquisition process is a Tcl interpreter with a largish chunk of C code which talks to the hardware (via RS485 and a custom PCI card).

I'm wondering about the rationale behind the allocation of the fd_set for the select() call in bsd-poll.c. Is there a reason we're dynamically allocating the fd_sets using nmemb, rather than simply putting three fd_set variables on the stack, followed by FD_ZERO calls? This seems to make life more difficult, as evidenced by the "goto out" statement, needed to free the memory.

I read this in a previous post ( http://rubyforge.org/pipermail/mongrel-users/2006-December/002354.html) .... First, Mongrel accepts remote clients and creates one Thread for each request. Mongrel also enforces a single request/response using Connect:close headers because Ruby only supports 1024 files (so far). If Mongrel doesn''t do this then people like yourself can write a simple
