Strange Stunnel crash (no errors, issues, anything)
by Alfred Kernaghan 17 May '13

17 May '13

Hi, Long time lurker, new poster though! I've got two servers running Stunnel v2.54 (yet to upgrade as I've been waiting for an x-forwardfor patch to become available). I noticed recently that one Stunnel nodes had exited, requiring a restart. I'm not sure if it's a co-incidence, but I've only just changed the cert on both installs last night. This, of course, is very concerning as it's only just become a problem, but being the core SSL endpoint, it knocks our server offline until it's … [View More]

I am getting a success with doing the configure, make and make install. However when I go to start up stunnel I get the following error message: Clients allowed=500 stunnel 4.56 on x86_64-unknown-linux-gnu platform Compiled/running with OpenSSL 1.0.1 14 Mar 2012 Threading:PTHREAD Sockets:POLL,IPv6 SSL:ENGINE,OCSP,FIPS Reading configuration from file /usr/local/etc/stunnel/stunnel.conf FIPS_mode_set: F06D065: error:0F06D065:common libcrypto routines:FIPS_mode_set:fips mode not supported Line 51:… [View More]

We are running stunnel and noticed an issue with what ended up being an issue creating a new thread due to running out of memory at 2gb - error (8) on create_client Are there any known issues with 4.53 around memory usage? We only terminate 2 ports against the installation 443 on 2 different interfaces / IP addresses and we ran into this issue with just under 5000 total connections We are not doing ECDH , but are using a 1024-bit param file

I've got dozens of clients connecting with Stunnel to a group of 5 servers. Each system has a config that looks like this: > cert = /etc/stunnel/zookeeper.pem > key = /etc/stunnel/zookeeper.key > CAfile = /etc/stunnel/zookeeper_ca.pem > verify = 2 > delay = yes > sslVersion = TLSv1 > client = yes > setuid = stunnel4 > setgid = stunnel4 > pid = /var/lib/stunnel4/zookeeper.stunnel4.pid > socket = l:TCP_NODELAY=1 > socket = r:TCP_NODELAY=1 > TIMEOUTconnect = … [View More]

Hello all! I'm in charge of activating stunnel to connect a service to a remote service. Since I'm totally new on this product, I'd be grateful if someone could help me in configuring.

Inconsistent performance across stunnel and/or OpenSSL versions
by PPingPongBaker PPingPongBaker 23 Apr '13

Hi All, I am experimenting with stunnel inside a VM on Xenserver 6.02. So this may not be a "common" use case, nonetheless, I would like to point out the issue. It is a basic setup as follows with 3 VMs running "ab" for webclient, stunnel+haproxy combo as the https/http bridge and nginx as the webserver. client VM (ab) <-> stunnel + haproxy VM <-> webserver VM (nginx) Specs on the stunnel VM are 2GB RAM, single-core dedicated 2.5 GHz Xeon E5-2640 vCPU, running Debian Squeeze 2.6.… [View More]

limited number of ports
by Terren Suydam 09 Apr '13

09 Apr '13

Hi, There appears to be a limit to the number of services you can define. Services beyond the 64th service appear to get set up without any log warnings or errors, yet don't pass traffic. The code uses select() & FD_SET to accept() an incoming connection & in Windows (using Windows Server 2008) the default is 64 sockets for that so wondering if I can just recompile, setting FD_SETSIZE to something larger. I'll try it either way, just wanted to put it out there to see if anyone … [View More]
