No Taskbar Icon
by Carter Browne 26 Sep '14

26 Sep '14

I have updated stunnel to version 5.04 on Windows 7 32 & 64 bit, Windows Server 2008R2, Windows Server 2012 and Windows Server 2012R2 and in no case does the icon appear. I explicitly set taskbar = yes in the configuration file. -- Carter Browne cbrowne(a)cbcs-usa.com

"Socket operation on non-socket" when trying to pass the configuration file as a file descriptor on OSX
by Guylhem 24 Sep '14

Hello I'm trying to pass the configuration file with option fd. However, I get the following errors when I do : echo my configuration | stunnel -fd 0 This is not related to echo since I get the same errors with: cat conf | stunnel -fd 0 stunnel is just filling my logs with : 2014-07-13 6:48:46.675 PM stunnel[1959]: LOG3[140735238959888]: local socket: Socket operation on non-socket (38) 2014-07-13 6:48:46.676 PM stunnel[1959]: LOG3[140735238959888]: local socket: Socket operation on non-socket (38) (...) stunnel ./conf works fine I found a reference to a bug that caused this same error message on OSX when run in inetd mode, but nothing else.

Stunnel as windows service doesn't start on restart.
by John Smith 24 Sep '14

24 Sep '14

Running stunnel 5.03 on Windows 2008 R2. Everything is installed and working fine. I can even start/stop the service no problem... (Pretty sure the service is set to start Automatically) When I reboot my server stunnel service shows as started but nothing gets logged and none of my connections work. Once I restart the service through service manager, everything works. So on startup it doesn't seem to run... This only happens if i reboot the machine. I also asked the same question here: http://serverfault.com/questions/627932/stunnel-as-windows-service-doesnt-s… Output of my logs proving it works. 2014.09.11 15:57:48 LOG5[1612]: stunnel 5.03 on x86-pc-msvc-1500 platform 2014.09.11 15:57:48 LOG5[1612]: Compiled/running with OpenSSL 1.0.1i-fips 6 Aug 2014 2014.09.11 15:57:48 LOG5[1612]: Threading:WIN32 Sockets:SELECT,IPv6 SSL:ENGINE,OCSP,FIPS 2014.09.11 15:57:48 LOG5[1612]: Reading configuration from file stunnel.conf 2014.09.11 15:57:48 LOG5[1612]: FIPS mode disabled 2014.09.11 15:57:49 LOG5[1612]: Configuration successful

Possible problem found in init script with 'dirty' config file
by F. J. Blanco 23 Sep '14

23 Sep '14

Hi there. Perhaps this is a foolishness, but it happens to me, triggering a great headache. I'm Debian (Wheezy) user, using stunnel 4.53-1.1. I copied the stunnel configuration from another machine for a simple LAN SMTP relay. When I tried to reload the script, I got this: # /etc/init.d/stunnel4 start > Reloading configuration SSL tunnels: /etc/init.d/stunnel4: 34: test: /var/lib/stunnel4/: unexpected operator A few hours laters, I discovered the problem was in config file, in the chroot parameter: chroot = /var/lib/stunnel4 Specifically, with a hide space at the end of the line: chroot = /var/lib/stunnel4[ ] In the init script, in the function get_pids(), this mistake caused that this checkout fails: --- if test -f $CHROOT/$PIDFILE; then cat $CHROOT/$PIDFILE fi --- 'cat /var/lib/stunnel4///stunnel.pid' is not the same as 'cat /var/lib/stunnel4/[ ]//stunnel.pid' Perhaps a suggestion, a little change here: CHROOT=`grep "^chroot" $file|sed "s;.*= *;;"` Adding a space filter: CHROOT=`grep "^chroot" $file|sed "s;.*= *;;" | tr -d " "` Regards.

John. Looks fine to me. Same configuration works in my Windows 7 64 bits. I have no access to Windows Server 2008 R2, but I would expect it to work the same. What are you securing with stunnel?...

Support for PSK
by Thomas Conté 21 Sep '14

21 Sep '14

Hello everyone, In the context of an embedded project, I have developed a lightweight, PolarSSL-based TLS-PSK client running on an Arduino board. Now I am looking for a generic server-side solution to connect the TLK-PSK client to a few Web services living in various app servers (Node.JS, IIS, and others). Since PSK support is not widespread, I am thinking about using stunnel as a generic front-end to these services. I have done a quick-and-dirty POC of adding PSK support to stunnel and it looks like this could be done with minor modifications, e.g. adding a call to SSL_CTX_set_psk_server_callback and the corresponding callback to ctx.c. Right now the psk_key and psk_identity values are hard-coded, so of course those need to be added to the configuration file. Is the community interested in further work in that area? Or is PSK support already in the stunnel roadmap? Cheers, -- Thomas Conté.

GnuTLS port
by Max 20 Sep '14

20 Sep '14

Pardon if that was asked before, but are there port of stunnel to GnuTLS available somewhere? With recent fallout from heartbleed I'm looking into getting rid of openssl (besides I've never liked the license anyway :) and stunnel is one of the very few programs which got dependency on it. cheers, Max.

400 - Bad Request
by j nasty 17 Sep '14

17 Sep '14

I'm trying to access a web service endpoint using sTunnel to handle all the SSL traffic. For my other connection setups this works perfectly fine. But for this one particular client I'm getting a 400 - Bad Request Error. Client Configuration looks like this: [Connection1] client = yes accept = 127.0.0.1:9006 connect = server.com:443 Response I get back is: <!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN"> <html><head> <title>400 Bad Request</title> </head><body> <h1>Bad Request</h1> <p>Your browser sent a request that this server could not understand.<br /> Reason: You're speaking plain HTTP to an SSL-enabled server port.<br /> Instead use the HTTPS scheme to access this URL, please.<br /> <blockquote>Hint: <a href="https://server.com/"><b>https://server.com/</b></a></blockquote></p> </body></html> Is there a setting configuration I can use so that sTunnel redirects to https://server.com instead of server.com:443? Thanks in advance, Jake

Stunnel Windows Server 2008 R2

I have installed stunnel 5.03 on Windows Server 2008 R2 X64. When I run it as an application it works perfectly. When I install and run the service, it starts but the start notice window, title bar, says Stunnel 5.03 win32 (not configured). It appears that the stunnel service is not reading the stunnel.conf. If anyone has any suggestions how I can successfully run stunnel as a service, I would be very appreciative. Thank you!

Odd complication between VM clients, same host
by afpteam＠sbcglobal.net 24 Aug '14

24 Aug '14

Hi, Much appreciation to Stunnel and OpenSSL for a long, successful provision. I can't be sure yet if the concern below is Stunnel or OpenSSL related. I've surfed Google and found nothing similar. Stunnel package with integral OpenSSL is current release. I recently had to secure and connect two public facing client machines on the same Citrix Xen 6.2 release, running Server 2003 x 64 bit. I typically use Stunnel with self generated Pem, for securing short term TightVNC sessions. The config is always fairly generic, loopback allowed, securing across 127.0.0.1 Typically I don't make name references in the .conf profile, just accept / connect on related ports. This is the first time I recall ever pointing two VM's at each other. I have tried both service and gui on both Stunnel and VNC. Tried both application listing and discrete port listing in the server's windows firewall. I have tried updating security to the Admin account as owner or Administrators, in general. I have tried launching either or both as Administrator. When VNC client viewer calls to Server, Stunnel sees the connect, succeeds the Pem and stops. If I restart the stunnel service at the server, the viewer auth dialog suddenly succeeds. I question if this remains secured but clearly isn't practical for application. Both VM's are connected to me via RDP at the time, if this might relate to an Auth violation. I tried multiple VMs to eliminate anything related to a bungled VM config. I'm guessing there is some kind of circular routing restriction possibly. Citrix does use an X-window console to each VM on the control path, but in other instances there's never been any conflict. Not sure how to determine if the issue is config, Stunnel or OpenSSL or how to resolve it. Any suggestions would be appreciated. Regards and thank you again, Mike

verify=4
by oweijr oweirj 12 Aug '14

12 Aug '14

Hello, In the stunnel documentation, I see the following: level 4 Ignore CA chain and only verify peer certificate. My interpretation of level 4 was that only the server certificate had to be installed on the client in order for the cert verification to pass. No issuer/CA certificates were needed. However, when I do this, the connection fails. I see this following in the logs with verify=4: 2014.08.12 21:17:57 LOG7[26768]: Starting certificate verification: depth=0, subject=/C=US/CN=a.b.com 2014.08.12 21:17:57 LOG4[26768]: CERT: Verification error: unable to get local issuer certificate 2014.08.12 21:17:57 LOG4[26768]: Certificate check failed: depth=0, subject=/C=US/CN=a.b.com 2014.08.12 21:17:57 LOG7[26768]: SSL alert (write): fatal: unknown CA 2014.08.12 21:17:57 LOG3[26768]: SSL_connect: 14090086: error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed My config file contains the following: verify = 4 CAfile = /opt/stunnel/certs/clients.pem chroot = /opt/stunnel setuid = stunnel setgid = stunnel pid = /run/stunnel.pid debug = 7 output = stunnel.log options = NO_SSLv2 cert = /opt/stunnel/certs/server.pem key = /opt/stunnel/certs/server.pem If I append the issuer certificate to the CAfile, after the peer certificate, then the connection is successful with verify=4. Is this expected behavior? Is there a verify level that works as I described above: only the peer certificate needs to be present, no CA/issuer certificates at all? Thank you for your help.

Windows Certificate Store
by j nasty 07 Aug '14

07 Aug '14

I haven't been able to get a definitive answer and can't find the information I need through traditional searching around. Anyways, is it possible to have sTunnel access the Windows certificate store to get the certificate that will be used for client authentication? If so, how can this be configured in sTunnel's configuration file? Or can you at least point me in the direction I can find the information I'm looking for? Many thanks in advance everyone!

Possible false positive trojan detection on stunnel-5.02-installer.exe
by Drew Mayo 06 Aug '14

06 Aug '14

Hi all, This is just an FYI. I'm a recent user of stunnel, and one of my team has just alerted me that f-prot (and unfortunately hence google drive) detects the current windows installer for stunnel 5.02 as a trojan. virustotal (which confirms it matches the sha256) tells me that the file is detected as: W32/Trojan.TDWH-2255 W32/Trojan3.JUA I've raised a misclassification request with f-prot, but of course that will probably take some time to get resolved. Of course, it is remotely possible it's not false, but i'm betting the other way. -d

More peer cert info export, new verify option
by Michal Vaško 05 Aug '14

05 Aug '14

Hello, for our current use-case we needed to add functionality to stunnel and therefore have made few patches. We distribute these patches with our software and were wondering what do you think about including them directly in stunnel. Firstly, we need peer certificate fingerprints in MD5, SHA1, SHA224, SHA256, SHA384 and SHA512. Patched stunnel exports all these in separate variables "SSL_CLIENT_*". Secondly, we could need subjectAltName values. Patched stunnel exports these in "SSL_CLIENT_SAN", but only rfc822Name, iPAddress and dNSName as we need only these. It could easily be expanded to all the values. Lastly, we required verification as if we first used verify = 2 and after failing trying verify = 4 (verify = 3 is technically verify = 2 AND verify = 4, if I am not wrong, and we need verify = 2 OR verify = 4). For this purpose my patch adds new verify = 5 option. I want to say that we did not just make all these requirements up, but we want to conform to RFCs describing NETCONF over TLS and its configuration. All the patches are included so you can go through them. Thank you. Kind regards, Michal Vasko

OpenVPN over stunnel
by Derek Cole 24 Jul '14

24 Jul '14

Hello, I am doing something similar to what is happening in this scenario: http://kyl191.net/2012/12/tunneling-openvpn-through-stunnel/ That is, I have set my openvpn client configuration to be "remote localhost port" where port is the port my stunnel client is listening on the same box as my openvpn client. This seems to work - I get connected to OpenVPN server fine, however, I don't seem to be able to ping the openvpn server by either of it's public or private ip addresses. In fact, it seems like when I do a tcpdump on the stunnel server, I don't see any incoming traffic on port 443. How is it possible that I am getting the VPN connection, but then the rest of the traffic just sort of stops going through stunnel? My stunnel client service looks like the following: [openvpn] accept = 127.0.0.1:5150 connect = stunnelserver:443 and my stunnel server looks like: [ovpnout] cert = mycert.pem accept = 443 connect = openvpn server Any ideas?

FIPS compliant Stunnel build
by Michael Curran 23 Jul '14

23 Jul '14

Hello -- Is Stunnel (any version) compatible with Fips-2.0 for compliance? I have found one individuals instructions for compiling fips-2.0.5 , but he calls out a prefix= in his configure for FIPS which breaks 140-2 compliance rules and makes the build no longer viable >From the Fips-2.0 userguide "Note that as a condition of the FIPS 140-2 validation no other user specified configuration optionsmay be specified. This restriction means that an optional install prefix cannot be specified –however, there is no restriction on subsequent manual relocation of the generated files to thedesired final location." I know that Stunnel compiles just fine with OpenSSL1.0.1 versions, but there appears to have been a difference in the method of validation and installation of FIPS modules into a seperate modular directory, and is not located in the openssl/include files after build now The stunnel configure script only looks for fips-1.0 as well , so my base assumption is might not be capable of handling FIPS-2.0 at this time.

Question in using stunnel
by Sara Baghbanzadeh 02 Jul '14

02 Jul '14

Hi there, I have a proxy (PHP file) which I want it to work as a server for me. I have PhantomJS as my client which loads particular url and instead of sending its requests to the main server it will send them to my proxy. I am going to send it back its responses. I have no problem when the website is based on HTTP. But, since my proxy cannot deal with SSL, I have problem with HTTPS websites. Actually, I have a database contains all the requests and responses which I captured by Fiddler. I use this database when I want to send a response to PhantomJS. Now, I cannot fill out my database since I cannot capture completely decrypted traffic using none of existing tools. Also I need to receive decrypted request from PhantomJS! Therefore, I decided to use stunnel for solving my problem. I am going to use it in order to decrypt all the requests from PhantomJS, and then, send them to my proxy, and also encrypt all my responses, before sending back to PhantomJS. I have installed latest version of stunnel on my Ubuntu machine and have generated a config file. I could not solve my problem using stunnel so far and my question is: Can stunnel solve my problem? I mean, can I use stunnel in order to decrypt PhantomJS's requests and encrypt my responses? ... If yes, could you please tell me how? Thank you so much and I am eagerly waiting to receive your response. Thanks in advance, Best regards, Sara

Re: [stunnel-users] OpenSSL FIPS header not found - version 5.02

No, you don't need to do "make depend". Just follow my exact steps, it is enough to compile a FIPS enabled stunnel. I did it on the 64 bits centos linux (linux-x86_64) and redhat linux (linux-generic32) , so that is probably the only change you need. Good luck.

public domain [PATCH] to stunnel v456 to clear SSL_OP_LEGACY_SERVER_CONNECT
by Simner, John 25 Jun '14

25 Jun '14

Dear Michal, Dear All, Please find attached a patch to stunnel 4.56 to clear SSL_OP_LEGACY_SERVER_CONNECT. There was a security requirement to ensure that the stunnel client could not connect to unpatched servers. I am aware from OpenSSL (https://www.openssl.org/docs/ssl/SSL_CTX_set_options.html ) that this parameter is currently set by default and has to be manually cleared by calling SSL_CTX_clear_options() or SSL_clear_options()if an OpenSSL client applications wants to ensure they can not connect to unpatched servers (and thus avoid any security issues). The attached patch achieves this. OpenSSL also state "As more servers become patched the option SSL_OP_LEGACY_SERVER_CONNECT will not be set by default in a future version of OpenSSL" so this patch is only required until OpenSSL change the default value.

Can not get TLS1.2 work in FIPS mode.
by Hui Yu 19 Jun '14

19 Jun '14

Hi all: Base on this link https://www.stunnel.org/sdf_ChangeLog.html, to make TLS 1.2 work, I need to put stunnel in FIPS enable mode. In stunnel config file, I have following to enable FIPS mode and select TLS 1.2. sslVersion=TLSv1.2 FIPS = yes But when my TLS 1.2 client send "client hello" with version TLS 1.2 to stunnel, stunnel still send "server hello" with TLS 1.0 back.

Configure stunnel to clear SSL_OP_LEGACY_SERVER_CONNECT to prevent connections to unpatched servers.
by Simner, John 19 Jun '14

19 Jun '14

Hi, I have a requirement for a stunnel client built with openSSL 0.9.8y to not connect to unpatched servers. I know this is a simple matter of using SSL_CTX_clear_options(ctx, SSL_OP_LEGACY_SERVER_CONNECT); Is there any way of configuring stunnel to clear this option? If this is the wrong approach, how can I prevent stunnel connecting to unpatched servers? Thank you for your assistance and look forward to your response.

Marco, I don't think stunnel changes the user ID without a 'setuid = ' statement in the configuration file (as it does not know which user ID to switch to). Are you sure, swat isn't changing the user ID? Does it work without being wrapped by stunnel?

Client SSL certificate
by reg14＠rambler.ru 13 Jun '14

13 Jun '14

If a client application is behind NAT, it does not have a real IP address. Certificate field 'common name' is supposed to contain a fully qualified domain name or a real IP address. Could the value of this field be ignored on SSL verification?

Using SNI in stunnel server
by Derek Cole 13 Jun '14

13 Jun '14

Hello, I have the following config on my stunnel server: Dereks-MacBook-Pro:server derek$ cat server.conf ;setuid = stunnel setgid = nogroup foreground = yes pid = /etc/stunnel/stunnel.pid debug = 7 output = /etc/stunnel/stunnel.log options = NO_SSLv2 verify = 3 fips=no CAfile=/Users/derek/cert_attempts/root_certs/cacert.pem CApath=/Users/derek/cert_attempts/server/trusted/ [https] cert = /Users/derek/cert_attempts/server/domain.local.pem accept = 443 connect = 80 ;connect is the far-end openvpn connection [exit1] sni = https:exit1.domain.local cert = /Users/derek/cert_attempts/server/exit1.domain.local.pem connect=ovpn1:16081 [exit2] sni = https:exit2.domain.local cert=/Users/derek/cert_attempts/server/exit2.domain.local.pem connect=ovpn2:1195 I am trying to test whether this is working by using openssl s_client with something similar to the following: openssl s_client -connect 10.22.1.219:443 -cert ./server/domain.local.pem -servername exit2.domain.local Maybe I misunderstand - but why do I have to specify -servername there? I thought that if I specified -cert and it matched any of the cert= in my services that are in my stunnel configuration, it would automatically know to do that connect? It seems like if I level off -servername entirely, it always defaults to https no matter what cert I specify, and if I do have -servername, it always goes to that SNI regardless of what cert I use (or whether that cert is even valid). All three of these .pem files were generated and signed by the same CA that I created, and they all contain the public and private key. What am I doing wrong here? Thanks

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Dear Users, I have released version 5.02 of stunnel. The ChangeLog entry: Version 5.02, 2014.06.09, urgency: HIGH: * Security bugfixes - OpenSSL DLLs updated to version 1.0.1h. See http://www.openssl.org/news/secadv_20140605.txt * New features - Major rewrite of the protocol.c interface: it is now possible to add protocol negotiations at multiple connection phases, protocols can individually decide whether the remote connection will be established before or after SSL/TLS is negotiated. - Heap memory blocks are wiped before release. This only works for block allocated by stunnel, and not by OpenSSL or other libraries. - The safe_memcmp() function implemented with execution time not dependent on the compared data. - Updated the stunnel.conf and stunnel.init templates. - Added a client-mode example to the manual. * Bugfixes - Fixed "failover = rr" broken since version 5.00. - Fixed "taskbar = no" broken since version 5.00. - Compilation fix for missing SSL_OP_MSIE_SSLV2_RSA_PADDING option.

behavior change after enabling proxy protocol
by Philippe Anctil 05 Jun '14

05 Jun '14

Hello, We use stunnel to secure a proprietary tcp/ip protocol over the internet. More specifially we have - 1 balancer - 2 stunnel boxes - 1 app server The load balancer 'pings' stunnel boxes regularly to know if one is down. Recently, we have added support for the proxy protocol in our app and turned it on in our stunnel config. It works great except for one small new behavior: upon receiving a load balancer ping, stunnel performs a connection on our app (and sends the proxy header). I ran a tcpdump for a telnet on the stunnel port (8000). With proxy protocol disabled, stunnel does nothing while it waits for the certificate. The connection ended at my request. 17:33:08.537385 IP 127.0.0.1.6015 > 127.0.0.1.8000: S 356922015:356922015(0) win 32792 <mss 16396,sackOK,timestamp 1085620573 0,nop,wscale 7> 17:33:08.537386 IP 127.0.0.1.8000 > 127.0.0.1.6015: S 1525966521:1525966521(0) ack 356922016 win 32768 <mss 16396,sackOK,timestamp 1085620573 1085620573,nop,wscale 7> 17:33:08.537393 IP 127.0.0.1.6015 > 127.0.0.1.8000: . ack 1 win 257 <nop,nop,timestamp 1085620573 1085620573> 17:33:19.750431 IP 127.0.0.1.6015 > 127.0.0.1.8000: F 1:1(0) ack 1 win 257 <nop,nop,timestamp 1085631785 1085620573> 17:33:19.751065 IP 127.0.0.1.8000 > 127.0.0.1.6015: . ack 2 win 256 <nop,nop,timestamp 1085631786 1085631785> 17:33:19.751794 IP 127.0.0.1.8000 > 127.0.0.1.6015: R 1:1(0) ack 2 win 256 <nop,nop,timestamp 1085631787 1085631785> With proxy protocol enabled, stunnel establishes a connection to my app and sends the proxy protocol before even receiving the certificate. 17:34:35.370462 IP 127.0.0.1.6026 > 127.0.0.1.8000: S 2949098861:2949098861(0) win 32792 <mss 16396,sackOK,timestamp 1085707402 0,nop,wscale 7> 17:34:35.370475 IP 127.0.0.1.8000 > 127.0.0.1.6026: S 1044893129:1044893129(0) ack 2949098862 win 32768 <mss 16396,sackOK,timestamp 1085707402 1085707402,nop,wscale 7> 17:34:35.370481 IP 127.0.0.1.6026 > 127.0.0.1.8000: . ack 1 win 257 <nop,nop,timestamp 1085707402 1085707402> 17:34:35.371035 IP 127.0.0.1.37654 > 127.0.0.1.9000: S 801705083:801705083(0) win 32792 <mss 16396,sackOK,timestamp 1085707402 0,nop,wscale 7> 17:34:35.371046 IP 127.0.0.1.9000 > 127.0.0.1.37654: S 4068822820:4068822820(0) ack 801705084 win 32768 <mss 16396,sackOK,timestamp 1085707402 1085707402,nop,wscale 7> 17:34:35.371052 IP 127.0.0.1.37654 > 127.0.0.1.9000: . ack 1 win 257 <nop,nop,timestamp 1085707402 1085707402> 17:34:35.371583 IP 127.0.0.1.37654 > 127.0.0.1.9000: P 1:44(43) ack 1 win 257 <nop,nop,timestamp 1085707403 1085707402> 17:34:35.371595 IP 127.0.0.1.9000 > 127.0.0.1.37654: . ack 44 win 256 <nop,nop,timestamp 1085707403 1085707403> 17:34:50.484991 IP 127.0.0.1.9000 > 127.0.0.1.37654: F 1:1(0) ack 44 win 256 <nop,nop,timestamp 1085722515 1085707403> 17:34:50.485892 IP 127.0.0.1.37654 > 127.0.0.1.9000: . ack 2 win 257 <nop,nop,timestamp 1085722516 1085722515> 17:35:08.824661 IP 127.0.0.1.6026 > 127.0.0.1.8000: F 1:1(0) ack 1 win 257 <nop,nop,timestamp 1085740854 1085707402> 17:35:08.824906 IP 127.0.0.1.8000 > 127.0.0.1.6026: . ack 2 win 256 <nop,nop,timestamp 1085740854 1085740854> 17:35:08.824972 IP 127.0.0.1.37654 > 127.0.0.1.9000: R 44:44(0) ack 2 win 257 <nop,nop,timestamp 1085740854 1085722515> 17:35:08.825013 IP 127.0.0.1.8000 > 127.0.0.1.6026: R 1:1(0) ack 2 win 256 <nop,nop,timestamp 1085740855 1085740854> Note I used 'tcpdump -i lo -nn port 8000 or port 9000' for both traces.

log format
by Philippe Anctil 04 Jun '14

04 Jun '14

I have noticed stunnel 5.01 log format is different when I run it under my account vs when I run it on the system. I don't remember seeing this with stunnel 4.56 and older. Format under my account: 2014.06.02 11:38:50 LOG6[26855]: SSL accepted: new session negotiated Format on the system: Jun 4 16:27:14 hostname stunnel: LOG6[11100:0]: SSL accepted: new session negotiated When I run under my account I normally save output to a separate file with output=. I guess this is what is having an influence on the log format? Is there any way I can have logging format in my account consistent with what I have in syslog? Thanks. -- Philippe Anctil

Problem with pidfile
by reg14＠rambler.ru 30 May '14

30 May '14

I run stunnel (version 5.00) as a non-root user which does not have write permissions to /var/run. So I created file /var/run/stunnel.log with right access for that user -rw-r--r--. 1 stunnel stunnel 0 May 28 21:31 stunnel.pid When I start daemon, it writes to logfile the following 2014.05.28 22:18:44 LOG3[8878]: Cannot create pid file /var/run/stunnel.pid 2014.05.28 22:18:44 LOG3[8878]: create: File exists (17) It seems that it tries to create pidfile in /var/run, and ignores that the file is already exists. As a result, pid is not written to stunnel.pid, and daemon crashes. Could this be fixed?
