syslog communication using TLS with the help of stunnel
by Girish Kumar 24 Nov '15

24 Nov '15

Dear All, Currently we are using syslog communication without any security. That is using UDP protocol with the server listening on port number 514. This is unsecure. I want to use syslog over TLS that is over TCP . As of now in my project syslogd daemon is used. I am planning to use stunnel to achieve this. I have few questions. Please clarify * To support stunnel, syslogd should be on TCP and not on UDP? * Is stunnel is a daemon ? * My understanding is syslogd forwards messages to the stunnel local portal at port 61514. The local stunnel forwards data via the network to port 60514 to its remote peer. * I assume stunnel-5.26(stunnel-5.26.tar.gz) is the latest version and this can be used on linux Regards, Girish

Hi, The website and the documentation does not indicate and a Google search does not give any relevant results, so I would like to ask if Stunnel supports OCSP stapling? Thank you, Ádám

Compilation issues - AIX 6.1 XLC and GXLC
by Rob Lockhart 16 Nov '15

16 Nov '15

On AIX 6.1 using IBM's XLC compiler, I do "configure" and that successfully completes. However, when I "make", it fails due to the parameters "-fstack-protector" and "-fPIE"... apparently it couldn't find the files "stack-protector" and "PIE" as "-f" specifies a file. However, gcc and perhaps many other cc variants, "-f" specifies a compile option. I was able to compile with XLC by ripping out the "stack-protector" and "PIE" sections of "configure" and running "make" but it would be best to use the stack protector mechanisms used for AIX's XLC: https://www.ibm.com/developerworks/mydeveloperworks/blogs/b10932b4-0edd-4e6… Has anyone compiled Stunnel 5.26 using IBM's XLC without removing the stack-protector and PIE sections in the configure file? The other option is to use gxlc instead of xlc to map the GNU C compiler options to XLC options. Would that be preferred (less modification of configure file)? I was able to get that working, but still an unusually high number of warnings. http://geco.mines.edu/files/manuals/xlc/mapping.pdf The article above (from IBM) has "-qstackprotect=size=N" - what suggestion parameter to use for "N"? To be nice to everyone's mailbox, I have posted the logs here: Stunnel 5.26 AIX XLC - fails http://pastebin.ca/3250237 Stunnel 5.26 AIX GXLC - passes http://pastebin.ca/3250242 Thanks, -Rob

Virtual Machine/Server
by Duane Moody - Global Data Specialists 13 Nov '15

13 Nov '15

We are currently using Stunnel on a stand-alone PC to link a 3rd party application that monitors a Graphical User Interface application for alarm notification. Stunnel is used to link this 3rd party alarm notification software to be able to send message to Amazon Web Services for email distribution to the users/operators that need this information. IT would like to investigate having all applications operate from a server possibly running 2012 OS, in a virtual environment. The GUI and 3rd party software will operate in this environment and I wanted to see if Stunnel would have any issues continuing to send messages out to Amazon.

hex key support for psk
by Reese Wilson 29 Oct '15

29 Oct '15

I ran into an issue with PSK reading the key as ascii instead of hex. I had a gnutls-serv and gnutls-cli set up with a hex key, and I switched the server for one wrapped using stunnel, but using the same key in psk.txt was failing. I eventually got it working by converting the hex characters to binary and placing that in the contents of the file specified by PSKsecrets (psk.txt), but this won't work for certain scenarios. For example, what if the key contains ascii newline characters?

stunnel: symbol lookup error: stunnel undefined symbol: X509_check_host
by Ryan McLeod 20 Oct '15

20 Oct '15

Hello. I get the error in the subject on 64bit Ubuntu and Debian system (32bit is fine). I've installed from source: -openssl-1.0.2.d -stunnel-5.24 When first install stunnel, it complained about not being able to find an ssl library during the configure stage and said to reinstall openssl with -fPIC. I did that using the following line: CFLAG=-fPIC ./config shared Once I did that, stunnel installed just fine. But when I run stunnel, I get the error in the subject. I tried reinstalling stunnel with a configure option: --with-ssl=/usr/local/ssl/. But no change. Any suggestions would be great. Thanks. Ryan

Windows Mobile 6.5

Hello, Does Anyone know if the makece.bat for ARM actually functions anymore? I'd like to build the latest possible version of stunnel for a client that uses Window Mobile 6.5, but not if I have to go back to stunnel version 4.15, which appears to be the last time someone built binaries for it... Thanks! Jeff.

Dear subscribers I am new to this so I dont know if this is just wrong configuration (that does not trigger an error message). Searching on the web for the following problem shows someone reporting sth similar on a Linux machine. I am using the newest version of stunnel (5.24) on Windows 7 and there is an stunnel thread starting that takes 100% of one core forever. I have attached a ProcMon trace with activated Registry/Filesystem/Network/Process events. The thread starts at 22:03:55 (which is 30 seconds after stunnel-start and at a time at which I did not use stunnel). The events after that follow that event are my pressing exit. Attachements: stunnel config, procMon-trace Thank you!

Question about "forground = yes" and "output = FILE" combined options
by Michael Gebis 16 Oct '15

16 Oct '15

Hello. I have a question about the combination of the "foreground = yes" option combined with the "output = FILE" option. The man page says this: foreground = yes | no (Unix only) foreground mode Stay in foreground (don’t fork) and log to stderr instead of via syslog (unless output is specified). This implies that if you set both "foreground = yes" and "output = FILE", the log messages will not be sent to stderr and will instead be sent to the log file only. We'd like this behavior--it makes it easier for our scripts to distinguish startup errors parsing the config file (which are sent to stderr, since the log file isn't configured yet) vs. normal operation after the config file is parsed and the log file is established. However, it appears that if you specify "foreground = yes" and "output = FILE", log messages will go to *both* stderr and the output file. I guess I'm asking: is the documentation in conflict with the behavior, and if so, which is correct? It's possible I'm just misreading the man page. But in any case, here is a simple patch which changes the behavior to match our reading of the man page. It is against stunnel-5.22 but I believe it should be applicable to later versions as well. Thank you, Michael diff -ru stunnel-5.22.orig/src/log.c stunnel-5.22-foreground-outfile/src/log.c --- stunnel-5.22.orig/src/log.c 2015-06-16 06:16:35.000000000 -0700 +++ stunnel-5.22-foreground-outfile/src/log.c 2015-10-14 11:54:58.998254974 -0700 @@ -243,7 +243,8 @@ level<=opt->log_level #else (level<=opt->log_level && - global_options.option.foreground) + global_options.option.foreground && + !outfile) #endif ) ui_new_log(line);

Can stunnel do this and if so, how?
by Jason Lacoss-Arnold 15 Oct '15

15 Oct '15

I have a client and a server where the client isn't very good and the server requires a MASSL (Mutual Auth SSL aka client certificate authenticated) connection. I need to get one of two things to work. Either: 1) The client makes a non-SSL connection to stunnel on the local machine which then performs a MASSL connection to the server using a client certificate or 2) The client makes a plain SSL connection to stunnel on the local machine which then performs a MASSL connection to the server using a client certificate. Can stunnel be used in this manner? If so, would someone please give me some hints on configuration? For extra credit, it would be awesome if the client private key were stored in a pkcs11 device (HSM). Thank you, --Jason

Greetings, Running stunnel 5.25 latest beta (2015-10-15), but also had the same issues on 5.24 final.

It works great. I am using 2FA with an app-specific password. But I have also tried without 2FA. I am 100% certain the account name xxxx(a)outlook.com and the password are correct. As far as the config file goes, I've tried just about everything I could find on Google. Nothing works, always the same error message. I also experienced similar failures with Gmail. Any ideas?

prng_init failure
by Philip Craig 15 Oct '15

15 Oct '15

prng_init() is failing in 5.24 when cross-compiling with openssl due to a combination of two reasons: 1. The --with-random configure option is not supported when cross compiling. 2. The hardcoded /dev/urandom is no longer used if OPENSSL_NO_EGD is not defined. The following patch reverts the behaviour to how it was in 5.23, but probably the --with-random configure option should be supported too. --- stunnel-5.25.orig/src/ssl.c +++ stunnel-5.25/src/ssl.c @@ -207,7 +207,8 @@ NOEXPORT int prng_init(GLOBAL_OPTIONS *g return 0; /* success */ } s_log(LOG_DEBUG, "RAND_screen failed to sufficiently seed PRNG"); -#elif !defined(OPENSSL_NO_EGD) +#else +#ifndef OPENSSL_NO_EGD if(global->egd_sock) { if((bytes=RAND_egd(global->egd_sock))==-1) { s_log(LOG_WARNING, "EGD Socket %s failed", global->egd_sock); @@ -220,7 +221,7 @@ NOEXPORT int prng_init(GLOBAL_OPTIONS *g so no need to check if seeded sufficiently */ } } -#else +#endif /* try the good-old default /dev/urandom, if available */ totbytes+=add_rand_file(global, "/dev/urandom"); if(RAND_status())

[PATCH] only use aysnc-signal-safe functions after fork
by Philip Craig 15 Oct '15

15 Oct '15

POSIX requires that multi-threaded processes only use async-signal-safe functions after calling fork(). For more info on the problems this avoids, see the rationale at: http://pubs.opengroup.org/onlinepubs/9699919799/functions/pthread_atfork.ht… The specific problem this patch solves is that, when there are multiple simultaneous requests, stunnel is often hanging on a futex syscall when a child process calls free as a result of tls_alloc(). This problem is experienced when using uClibc. I haven't tested, but I believe the malloc implementation in glibc does not have this problem. --- stunnel-5.24.orig/src/client.c +++ stunnel-5.24/src/client.c @@ -1100,6 +1100,8 @@ NOEXPORT SOCKET connect_local(CLI *c) { NOEXPORT SOCKET connect_local(CLI *c) { /* spawn local process */ char *name, host[40], port[6]; + char *env[10]; + int i, envc; int fd[2], pid; X509 *peer_cert; #ifdef HAVE_PTHREAD_SIGMASK @@ -1115,19 +1117,55 @@ NOEXPORT SOCKET connect_local(CLI *c) { } else if(make_sockets(fd)) longjmp(c->err, 1); + set_nonblock(fd[1], 0); /* switch back to blocking mode */ + + envc = 0; + + if(!getnameinfo(&c->peer_addr.sa, c->peer_addr_len, + host, 40, port, 6, NI_NUMERICHOST|NI_NUMERICSERV)) { + /* just don't set these variables if getnameinfo() fails */ + env[envc++] = str_printf("REMOTE_HOST=%s", host); + env[envc++] = str_printf("REMOTE_PORT=%s", port); + if(c->opt->option.transparent_src) { +#ifndef LIBDIR +#define LIBDIR "." +#endif +#ifdef MACH64 + env[envc++] = str_dup("LD_PRELOAD_32=" LIBDIR "/libstunnel.so"); + env[envc++] = str_dup("LD_PRELOAD_64=" LIBDIR "/" MACH64 "/libstunnel.so"); +#elif __osf /* for Tru64 _RLD_LIST is used instead */ + env[envc++] = str_dup("_RLD_LIST=" LIBDIR "/libstunnel.so:DEFAULT"); +#else + env[envc++] = str_dup("LD_PRELOAD=" LIBDIR "/libstunnel.so"); +#endif + } + } + + if(c->ssl) { + peer_cert=SSL_get_peer_certificate(c->ssl); + if(peer_cert) { + name=X509_NAME2text(X509_get_subject_name(peer_cert)); + env[envc++] = str_printf("SSL_CLIENT_DN=%s", name); + name=X509_NAME2text(X509_get_issuer_name(peer_cert)); + env[envc++] = str_printf("SSL_CLIENT_I_DN=%s", name); + X509_free(peer_cert); + } + } + + env[envc] = NULL; pid=fork(); c->pid=(unsigned long)pid; switch(pid) { case -1: /* error */ + for (i = 0; i < envc; i++) + str_free(env[i]); closesocket(fd[0]); closesocket(fd[1]); ioerror("fork"); longjmp(c->err, 1); case 0: /* child */ - tls_alloc(NULL, c->tls, NULL); /* reuse thread-local storage */ closesocket(fd[0]); - set_nonblock(fd[1], 0); /* switch back to blocking mode */ /* dup2() does not copy FD_CLOEXEC flag */ dup2(fd[1], 0); dup2(fd[1], 1); @@ -1135,36 +1173,6 @@ NOEXPORT SOCKET connect_local(CLI *c) { dup2(fd[1], 2); closesocket(fd[1]); /* not really needed due to FD_CLOEXEC */ - if(!getnameinfo(&c->peer_addr.sa, c->peer_addr_len, - host, 40, port, 6, NI_NUMERICHOST|NI_NUMERICSERV)) { - /* just don't set these variables if getnameinfo() fails */ - putenv(str_printf("REMOTE_HOST=%s", host)); - putenv(str_printf("REMOTE_PORT=%s", port)); - if(c->opt->option.transparent_src) { -#ifndef LIBDIR -#define LIBDIR "." -#endif -#ifdef MACH64 - putenv("LD_PRELOAD_32=" LIBDIR "/libstunnel.so"); - putenv("LD_PRELOAD_64=" LIBDIR "/" MACH64 "/libstunnel.so"); -#elif __osf /* for Tru64 _RLD_LIST is used instead */ - putenv("_RLD_LIST=" LIBDIR "/libstunnel.so:DEFAULT"); -#else - putenv("LD_PRELOAD=" LIBDIR "/libstunnel.so"); -#endif - } - } - - if(c->ssl) { - peer_cert=SSL_get_peer_certificate(c->ssl); - if(peer_cert) { - name=X509_NAME2text(X509_get_subject_name(peer_cert)); - putenv(str_printf("SSL_CLIENT_DN=%s", name)); - name=X509_NAME2text(X509_get_issuer_name(peer_cert)); - putenv(str_printf("SSL_CLIENT_I_DN=%s", name)); - X509_free(peer_cert); - } - } #ifdef HAVE_PTHREAD_SIGMASK sigemptyset(&newmask); sigprocmask(SIG_SETMASK, &newmask, NULL); @@ -1176,11 +1184,13 @@ NOEXPORT SOCKET connect_local(CLI *c) { signal(SIGTERM, SIG_DFL); signal(SIGQUIT, SIG_DFL); signal(SIGINT, SIG_DFL); - execvp(c->opt->exec_name, c->opt->exec_args); + execve(c->opt->exec_name, c->opt->exec_args, env); ioerror(c->opt->exec_name); /* execvp failed */ _exit(1); default: /* parent */ s_log(LOG_INFO, "Local mode child started (PID=%lu)", c->pid); + for (i = 0; i < envc; i++) + str_free(env[i]); closesocket(fd[1]); return fd[0]; }

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 Dear Users, I have released version 5.24 of stunnel. The ChangeLog entry: Version 5.24, 2015.10.08, urgency: MEDIUM * New features - Custom CRL verification was replaced with the internal OpenSSL functionality. - *BSD support for "transparent = destination" and client-side "protocol = socks". This feature should work at least on FreeBSD, OpenBSD and OS X. - Added a new "protocolDomain" option for the NTLM authentication (thx to Andreas Botsikas). - Improved compatibility of the NTLM phase 1 message (thx to Andreas Botsikas). - "setuid" and "setgid" options are now also available in service sections. They can be used to set owner and group of the Unix socket specified with "accept". - Added support for the new OpenSSL 1.0.2 SSL options. - Added OPENSSL_NO_EGD support (thx to Bernard Spil). - VC autodetection added to makew32.bat (thx to Andreas Botsikas). * Bugfixes - Fixed the RESOLVE [F0] TOR extension support in SOCKS5. - Fixed the error code reported on the failed bind() requests. - Fixed the sequential log id with the FORK threading. - Restored the missing Microsoft.VC90.CRT.manifest file.
