Hi, This morning I stopped using the splash screen on boot on my FreeBSD 4.11 system, using stunnel 4.11 and now when I use stunnel I get: "stunnel[PID]: nonblocking: Operation not supported by device (19)" Why would changing if I use a splash screen or not make this difference?! Thanks, Tuc

Any examples of Stunnel usage in "enterprise environments"?
by Claus Lund 06 Aug '05

06 Aug '05

Hi everybody, I was just wondering if there are any public examples of widespread Stunnel usage in an enterprise environments? I'm a UNIX admin where I work and we are currently working on trying to find a solution for encrypting all network traffic to and from the UNIX machines (all the clients are using Windows boxes). We are running a variety of services on the boxes including Samba, homegrown services for our 3-tier app, Oracle, DB2 etc... I already have proof of concept setups for every network service that we offer but I think some "real-world examples" would go a long to convince my boss (and the Windows admins) that Stunnel is a viable option for us. Thank you in advance, Claus

Many times people have written in pointing out problems with stunnel crashing, dumping core, locking up, yet all you can offer is 'never report problems with older versions', 'you have no right to complain', etc etc, and now you have the arrogance to tell us all we have no clue how to report bugs. I get the feeling you are upset because so many of us discover problems with this software. Andrew

I was trying to see if it was a common issue when stunnel is unable to connect. I didn't ask for snide remarks. -----Original Message----- From: stunnel-users-bounces(a)mirt.net [mailto:[email protected]] On Behalf Of Michal Trojnara Sent: Thursday, August 04, 2005 3:48 AM To: stunnel-users(a)mirt.net Subject: Re: [stunnel-users] Stunnel dumping core "Stephen Tanner" <stanner(a)leeclerk.org> wrote: > Sometimes shutting it down while > it is doing this, it will dump core. Here is an axample of a good core dump error report. http://stunnel.mirt.net/pipermail/stunnel-users/2004-August/000009.html http://stunnel.mirt.net/pipermail/stunnel-users/2004-August/000015.html The report should include at least: - stunnel version line (for example "stunnel 4.05 on powerpc-ibm-aix5.2.0.0 FORK with OpenSSL 0.9.7d 17 Mar 2004"). - stack backtrace.

Stunnel dumping core
by Stephen Tanner 04 Aug '05

04 Aug '05

I've been running stunnel to tunnel syslog-ng messages to a loghost. On some occasions, be it a network maintenance issue or fluke, if a server loses connection to the loghost, stunnel starts spewing broken pipe messages to syslog. Sometimes shutting it down while it is doing this, it will dump core. Anyone have an idea on what might be causing this? =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= Stephen Tanner HP-UX Systems Administrator Network Support Services Lee County Clerk of Courts =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=

Error resolving '...' (Windows)
by Oliver Ackermann (infowing AG) 03 Aug '05

03 Aug '05

On a Windows 2000 machine I always get the following error when I try to start stunnel (4.11): Error resolving 'x.y.z.23': Neither nodename nor servname known (EAI_NONAME) The client should connect to a server using SSL. x.y.z.23 is a static IP address of the client. The client has multiple IP addresses and stunnel should use this one to connect to the server. Contents of stunnel.conf: client=yes [service] local=x.y.z.23 accept=12345 connect=server:12345 Why does stunnel try to "resolve" this IP? Is the configuration correct? Thanks for your help! Oliver

ftp support for stunnel-4.11 (still has errors, do not know why)
by ZHUANG YUYAO 03 Aug '05

03 Aug '05

hi, here is the initial patch (pre-pre-pre-alpha! just a demo/test) for adding ftp support to stunnel-4.11. Known bugs: 1) only tested under linux. debian 3.1 (testing), gcc version 3.3.5 (Debian 1:3.3.5-13) 2) ftp_alloc_port() in ftp.c is not yet finished. just a demo; 3) only works when configured with --with-threads=ucontext. does not work with --with-threads=pthread! 4) libwrap support is not tested. 5) only tested with flashfxp (3.0.2 build(1043) implicit SSL); 6) still contains memory leaks. 7) can only successfully transfer(RETR) small files whose size is less than about 90K bytes. stunnel hangs while transferring a larger file, looks like poll() in scan_waiting_queue() (network.c line 164) can not receive a POLLOUT event from ssl_wfd->fd after successfully transfered 90K bytes. the log file is also included in this mail. bug #7 really frustrats me. still do not know why. could anyone please give me some hints?
