Version 1.4a - fix up pid file generation (Xander Hudson) - fix up Makefile.in (Andrew Schulman) Version 1.4 - initialise ep in main() to avoid warning (Marcelo Goes) - fix where cast to int happens when calculating next time to poll connection (Omer Erdem Demir) - fix '--' use so can pass -M to autossh for session multiplexing - fix use of strcpy for overlapping copy in strip_arg (Filippo Giunchedi). - add basic GNU autoconf support and drop per-platform Makefiles (Andre Lucas) - pid file support (Ben Vitale) - arbitrary messages in echo string (Ron Yorston) Version 1.3 - fix AUTOSSH_DEBUG for Solaris and AIX - fix attempt to free() static storage (affected platforms without getaddrinfo() -- mostly cygwin) (Andrew Schulman) - change test and placement of typedef for socklen_t under OS X; new OS X defines it - add ability to signal autossh to kill and restart ssh child, using SIGUSR1 - add hostname to monitor message (Ron Yorston) - check on looping on poll() where connection has been lost (spinning and high CPU) - fix bug where length argument to accept() was not initialised - fix arg parsing bug where stripping -f from arguments would strip from a parameter to the argument: e.g -L8808:foo:80 would become -L8808:oo:80 (pointed out by Eric Larson) - pull out r/w loops in conn_test() into separate functions, makes logic more apparent - add echo port support: have the remote server use the inetd echo service to echo our test string back to us. Or use some other echo service. Idea and patch from Ron Yorston. This makes it 1.3. - remove bad strcpy() (left over from some testing?) thanks to Ron Yorston, change to memset read buffer to all zeros - fix ssh args when AUTOSSH_PORT=0 is used to turn monitor loop off (Karl Berry) - add more descriptive usage output, by popular request Version 1.2g - add AUTOSSH_NTSERVICE (Andrew Schulman) - fix bad calculation for seconds left in poll time (again from Andrew Schulman) - from Andrew Schulman: add support for older networking and cygwin - add AUTOSSH_MAXSTART (from Hugo Haas) - loop around waitpid() in ssh_kill() in case interrupted (thanks to Jens Krabbenhoeft) - update ssh argument string - move openlog above port error checking - handle environment variables and -M arg being set to the empty string (reported by Dan Christensen via Filippo Giunche) - add some rudimetary auto-adjust to the network timeouts for low poll times. So by default 15secs on each of accept() and poll()to deal with high-latency connections, but as poll time falls below 30secs, then adjust timeouts down as well. - adjust division in grace_time() to allow for low poll time - don't call shutdown() and close() on invalid socket () (found by Dmitry V. Levin) Version 1.2f - by popular request, support the -f flag by doing the fork/background ourselves, and not passing the flag to ssh (thanks to Dan Christensen for prodding me into it) - change timeout to from 5000 to 15000 ms to deal with reported issues with high-latency links; unused var removal; and man page typo (thanks to Michael Shields) Version 1.2e - check for attempt to use -f flag; exit as error - if AUTOSSH_GATETIME is 0, then disable any of the startup failure bailouts, and just retry - set SO_REUSEADDR on listening socket (Jedi One's suggestion) - show port number in some error messages - note in man page and README about -M 0 turning port monitoring off - remove duplicate include of sys/socket.h Version 1.2d - AIX support (thanks to Stefan Rodenstein) - fix argument rewrite bug when using AUTOSSH_PORT (thanks to Peter Williams) - log pid of ssh child just after fork Version 1.2c - use Marcus Friedl's suggestion to simply connect to "127.0.0.1" rather than "localhost", as not really using IPv6 anyway. And this gets rid of annoying ipv6 localhost message on Solaris at least. - support for MacOS X using Greg Parker's fakepoll. Version 1.2b (Thanks to Simon Easter for bug reports and trials) - fix file descriptor leak - setsockopt()'s don't work for Solaris either. Give up on them. - set close-on-exec for read socket so will be closed when ssh executed - do shutdown() before close() (paranoia) - close read socket before exit - pull read socket open and close up out of ssh_run() - cosmetic changes to some loops, get rid of newlines in some errlog strings. Version 1.2a - setsockopt() will not set timeouts on socket read/write ops under Linux 2.2 kernels (and earlier, I presume). So unless someone tells me we really need them, I've #ifdef'd the setsockopt()s out for Linux. - check value of fd returned by accept(). - Oh, there's a man page now. Unfortunately, it doesn't render for Solaris. Sorry, Solaris users are still stuck with the README. Version 1.2 - Major restructuring of code, mostly to support the change to a loop of forwarded ports to test the network connection. - Incremental back off on rate of connection attempts when there are rapid failures to establish/maintain a connection. Version 1.1b - change handling of ssh exit status - introduce "starting gate" time: ssh process that dies too early is deemed not to have made it out of the starting gate, and autossh exits. Version 1.1a - fix race after failure to exec ssh where parent will loop attempting to restart - add -V version flag - use strtoul() for environment option parsing - drop useless intermediate function ssh_setwatch() Version 1.1 Initial release
