[ANNOUNCEMENT] Updated: socat 1.7.2.4-1, 2.0.0-b7-1
Two new versions of socat are available in the Cygwin distribution: 1.7.2.4-1 - current 2.0.0-b7-1 - test These are new upstream releases, that address a security vulnerability (possible buffer overflow) in previous versions. Security advisory: http://www.dest-unreach.org/socat/contrib/socat-secadv5.txt Upstream changelog: http://www.dest-unreach.org/socat/doc/CHANGES. These versions also add IPv6 support (TCP6, TCP6-LISTEN, UDP6, UDP6-DATAGRAM, ...) for the first time in Cygwin. This feature hasn't been tested much yet, so please test and report any findings (good or bad) here. socat is a relay for bidirectional data transfer between two independent data channels. Each of these data channels may be a file, pipe, device (serial line etc. or a pseudo terminal), a socket (UNIX, IP4, IP6 - raw, UDP, TCP), an SSL socket, proxy CONNECT connection, a file descriptor (stdin etc.), the GNU line editor (readline), a program, or a combination of two of these. These modes include generation of 'listening' sockets, named pipes, and pseudo terminals. socat can be used, e.g., as TCP port forwarder (one-shot or daemon), as an external socksifier, for attacking weak firewalls, as a shell interface to UNIX sockets, IP6 relay, for redirecting TCP oriented programs to a serial line, to logically connect serial lines on different computers, or to establish a relatively secure environment (su and chroot) for running client or server shell scripts with network connections.

Indeed. Cygwin can't (and must not) change the permissions of existing files. But usually this shoudn't hurt, unless a file of a security sensitive application is affected. Thanks for testing!

Testing this on 64 bit, with socat 1.7.2.4, and a Linux peer in both directions works fine. Do you need a test of the 2.0 test version as well?

Enquiry on Cygwin function - file sharing between Windows and Windows
Dear Cygwin, Further to FAQ 4.28, we know that Cygwin can provide a SCP protocol for file sharing between Unix and Windows and we have been using this tool for years. My question is, can we do the same thing for file sharing between Windows and Windows? I know there are huge number of sftp applications can serve for the purpose but I am really interested can Cygwin support file sharing between Windows Servers platform.

Yes please, since 2.0 is where I had to apply a patch to remove the use of IPV6_DSTOPTS. I do have an ipv6 host here that I tested it on, but it would be good to have another test. -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple
strace and sigprocmask
Running on Windows 8.1, with 32-bit Cygwin v1.7.29. I've taken straces of a problematic area of xemacs, tidied them, and am trying to locate significant differences. I'm seeing something I don't understand, which isn't causing a crash so probably isn't significant, but I'd like to understand it better. strace 1 has: [main] PID1 sigprocmask: 0 = sigprocmask(2647444, 0xNULL, 0xNULL) where strace 2 has: [main] PID1 sigprocmask: 0 = sigprocmask(2649272, 0xNULL, 0xADDR) Similar lines appear frequently in both straces. Either I don't understand strace output, or this is bizarre -- the first arg to sigprocmask should always be 0, 1 or 2, right? I'd welcome any help in understanding how I should be reading this, and more generally, how I could have found the answer to my question myself. Thanks, ht -- Henry S.

This is a a bug (now fixed) in the source. The first argument to sigprocmask was not being sent to the strace printf, pushing all of the arguments left. As to how you could have found the answer, it's the standard answer for free software projects - look at the source. cgf -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple
Cygwin home looking at wrong directory
My IT just installed Cygwin on a machine with 2 drives c and d. They appear to have installed on both drives (not sure why!) How can I tell Cygwin which drive I want it to use? There is NO windows environment HOME variable set.

Also, i have noticed that 'getent group' produces this line: +Utilisateurs authentifiés:S-1-5-11:11: (with \303\251 meaning é, like under UTF-8) while 'getent passwd' produces (among other lines): +SERVICE RÉSEAU:*:20:20:,S-1-5-20:/:/sbin/nologin (with \311 meaning É, like under ISO-Latin) This is with LC_CTYPE=fr_FR, no /etc/nsswitch.conf, /etc/passwd and /etc/group with only one line each, domain member with currently no network connected, under Cygwin 32bits 'Just Me', installed on top of XP SP3 32bits [french only], with snapshot '20140508 19:51:25’, and all packages up-to-date. If i setenv LC_CTYPE C, or unsetenv LC_CTYPE, i also get UTF-8 for 'getent passwd' (ie for both). What bothers me is that under LC_CTYPE=fr_FR (or fr_FR@euro), the getent output is not consistent.

[ANNOUNCEMENT] Updated: screen 4.2.1-1
A new version of screen, 4.2.1-1, is available in the Cygwin distribution. This is a new upstream release. This release may or may not fix some of the known outstanding issues with screen: Scrolling breaks in shells inside screen: http://cygwin.com/ml/cygwin/2014-01/msg00223.html ssh segmentation fault within screen: http://cygwin.com/ml/cygwin/2014-05/msg00078.html I haven't had time to test any of those against this release yet, so test reports would be welcome. screen is a full-screen window manager that multiplexes a physical terminal between several processes, typically interactive shells. Each virtual terminal provides the functions of the DEC VT100 terminal and, in addition, several control functions from the ANSI X3.64 (ISO 6429) and ISO 2022 standards (e.g., insert/delete line and support for multiple character sets). There is a scrollback history buffer for each virtual terminal and a copy-and-paste mechanism that allows the user to move text regions between windows. When screen is called, it creates a single window with a shell in it (or the specified command) and then gets out of your way so that you can use the program as you normally would. Then, at any time, you can create new (full-screen) windows with other programs in them (including more shells), kill the current window, view a list of the active windows, turn output logging on and off, copy text between windows, view the scrollback history, switch between windows, etc. All windows run their programs completely independent of each other. Programs continue to run when their window is currently not visible and even when the whole screen session is detached from the user's terminal. Andrew E.
