Not all OSes have SA_RESTART (for instance, SunOS does not). Also, for the non-SA_RESTART case in scp.c sa.sa_flags was not being initialized (noted by dworkin at village.org). - todd --- scp.c.DIST Sat Feb 17 17:56:33 2001 +++ scp.c Sat Feb 17 17:57:59 2001 @@ -1224,8 +1224,9 @@ struct sigaction sa; sa.sa_handler = u...

I have attached two patches to the current source code. The first addresses the pty problems with UnixWare 2.x with connecting with SSH2. It sets the sigaction to SA_RESTART. This fixes UnixWare v2.x, but haven't heard any feedback as to effects on other OS'. The first patch is against misc.c. The second patch adds a section "*-*-sysv4.2uw2*" to configure to set the TEST_MINUS_S_SH shell and define USE_PIPES. I suspect these same fixes apply to Uni...

I am aware that there have been several posts related to ssh connections hanging, i have tried to read through most of them in the archives... I am posting this in hopes that it may present something new that will further help resolve this problem. The problem i am having appears to be similar to what others have reported where after typing exit in an interactive shell the connection is not

...s generally considered to be bad practice and should be avoided. SunOS provides the SA_INTERRUPT option, which is used to prevent system calls from being restarted. SA_INTERRUPT is not available on HP-UX, but is the default behavior of sigaction() on HP-UX (that is, does not restart signal calls). SA_RESTART is used on SunOS to make system calls restart. It is not available on HP-UX. Instead, the sigcontext parameter passed to the signal handler can be used within the signal handler itself to specify SIG_RESTART or SIG_RETURN after handling an interrupted system call: .. <code example>!!!! ------...
