Problem running Stunnel 4.05 on AIX 5.2
by Baker Nelson 23 Aug '04

23 Aug '04

Hi all, I am trying to run Stunnel 4.05 on AIX 5.2 to secure our homegrown webserver. I have been searching archives all over the place, and have yet to find the answer, but have found many comments here and there that seem to indicate a problem with Stunnel on AIX. The problem, in a nutshell, is that I get an error on SSL_read in the stunnel log and it shuts down with a segmentation fault after the first connection, no matter what I do. Configuration info attached below. Any help anyone can give would be greatly appreciatted. Thanks Baker stunnel 4.05 on powerpc-ibm-aix5.2.0.0 FORK with OpenSSL 0.9.7d 17 Mar 2004 Global options cert = /usr/local/etc/stunnel/stunnel.pem ciphers = ALL:!ADH:+RC4:@STRENGTH debug = 5 key = /usr/local/etc/stunnel/stunnel.pem pid = /usr/local/var/run/stunnel.pid RNDbytes = 64 RNDfile = /dev/urandom RNDoverwrite = yes session = 300 seconds verify = none Service-level options TIMEOUTbusy = 300 seconds TIMEOUTclose = 60 seconds TIMEOUTidle = 43200 seconds OpenSSL 0.9.7d 17 Mar 2004 conf-file: cert = /usr/local/ssl/stunnel.pem #chroot = /usr/local/var/run/stunnel/ pid = /usr/local/etc/stunnel/stunnel.pid setuid = HTTPD setgid = rrms #options = DONT_INSERT_EMPTY_FRAGMENTS # Some debugging stuff debug = 7 output = stunnel.log # Use it for client mode #client = yes foreground = yes # Service-level configuration [https] accept = 443 connect = 80 TIMEOUTclose = 0 stunnel - log (from running openssl s_client command to test setup): 2004.08.19 15:22:29 LOG5[16718:0]: stunnel 4.05 on powerpc-ibm-aix5.2.0.0 FORK w ith OpenSSL 0.9.7d 17 Mar 2004 2004.08.19 15:22:29 LOG4[16718:0]: Wrong permissions on /usr/local/ssl/stunnel.p em 2004.08.19 15:22:29 LOG7[16718:0]: Snagged 64 random bytes from //.rnd 2004.08.19 15:22:29 LOG7[16718:0]: Wrote 1024 new random bytes to //.rnd 2004.08.19 15:22:29 LOG7[16718:0]: RAND_status claims sufficient entropy for the PRNG 2004.08.19 15:22:29 LOG6[16718:0]: PRNG seeded successfully 2004.08.19 15:22:29 LOG7[16718:0]: Certificate: /usr/local/ssl/stunnel.pem 2004.08.19 15:22:29 LOG7[16718:0]: Key file: /usr/local/ssl/stunnel.pem 2004.08.19 15:22:29 LOG5[16718:0]: FD_SETSIZE=65534, file ulimit=65534 -> 31999 clients allowed 2004.08.19 15:22:29 LOG7[16718:0]: FD 4 in non-blocking mode 2004.08.19 15:22:29 LOG7[16718:0]: SO_REUSEADDR option set on accept socket 2004.08.19 15:22:29 LOG7[16718:0]: https bound to 0.0.0.0:443 2004.08.19 15:22:29 LOG7[16718:0]: FD 5 in non-blocking mode 2004.08.19 15:22:29 LOG7[16718:0]: FD 6 in non-blocking mode 2004.08.19 15:22:29 LOG7[16718:0]: Created pid file /usr/local/etc/stunnel/stunn el.pid 2004.08.19 15:22:30 LOG7[16718:0]: https accepted FD=7 from **ip**:33519 2004.08.19 15:22:30 LOG7[16718:0]: FD 7 in non-blocking mode 2004.08.19 15:22:30 LOG7[21344:0]: https started 2004.08.19 15:22:30 LOG5[21344:0]: https connected from **ip**:33519 2004.08.19 15:22:30 LOG7[21344:0]: SSL state (accept): before/accept initializat ion 2004.08.19 15:22:30 LOG7[21344:0]: SSL state (accept): SSLv3 read client hello A 2004.08.19 15:22:30 LOG7[21344:0]: SSL state (accept): SSLv3 write server hello A 2004.08.19 15:22:30 LOG7[21344:0]: SSL state (accept): SSLv3 write certificate A 2004.08.19 15:22:30 LOG7[21344:0]: SSL state (accept): SSLv3 write server done A 2004.08.19 15:22:30 LOG7[21344:0]: SSL state (accept): SSLv3 flush data 2004.08.19 15:22:30 LOG7[21344:0]: waitforsocket: FD=7, DIR=read 2004.08.19 15:22:30 LOG7[21344:0]: waitforsocket: ok 2004.08.19 15:22:30 LOG7[21344:0]: SSL state (accept): SSLv3 read client key exc hange A 2004.08.19 15:22:30 LOG7[21344:0]: SSL state (accept): SSLv3 read finished A 2004.08.19 15:22:30 LOG7[21344:0]: SSL state (accept): SSLv3 write change cipher spec A 2004.08.19 15:22:30 LOG7[21344:0]: SSL state (accept): SSLv3 write finished A 2004.08.19 15:22:30 LOG7[21344:0]: SSL state (accept): SSLv3 flush data 2004.08.19 15:22:30 LOG7[21344:0]: 1 items in the session cache 2004.08.19 15:22:30 LOG7[21344:0]: 0 client connects (SSL_connect()) 2004.08.19 15:22:30 LOG7[21344:0]: 0 client connects that finished 2004.08.19 15:22:30 LOG7[21344:0]: 0 client renegotiatations requested 2004.08.19 15:22:30 LOG7[21344:0]: 1 server connects (SSL_accept()) 2004.08.19 15:22:30 LOG7[21344:0]: 1 server connects that finished 2004.08.19 15:22:30 LOG7[21344:0]: 0 server renegotiatiations requested 2004.08.19 15:22:30 LOG7[21344:0]: 0 session cache hits 2004.08.19 15:22:30 LOG7[21344:0]: 0 session cache misses 2004.08.19 15:22:30 LOG7[21344:0]: 0 session cache timeouts 2004.08.19 15:22:30 LOG6[21344:0]: Negotiated ciphers: AES256-SHA S SLv3 Kx=RSA Au=RSA Enc=AES(256) Mac=SHA1 2004.08.19 15:22:30 LOG7[21344:0]: FD 4 in non-blocking mode 2004.08.19 15:22:30 LOG7[21344:0]: https connecting 127.0.0.1:80 2004.08.19 15:22:30 LOG7[21344:0]: Remote FD=4 initialized 2004.08.19 15:22:32 LOG7[21344:0]: Socket closed on read 2004.08.19 15:22:32 LOG7[21344:0]: SSL write shutdown (output buffer empty) 2004.08.19 15:22:32 LOG7[21344:0]: SSL alert (write): warning: close notify 2004.08.19 15:22:32 LOG7[21344:0]: SSL_shutdown retrying 2004.08.19 15:22:32 LOG7[21344:0]: select timeout waiting for SSL close_notify 2004.08.19 15:22:32 LOG5[21344:0]: Connection closed: 311 bytes sent to SSL, 9 b ytes sent to socket 2004.08.19 15:22:32 LOG7[21344:0]: removing pid file /usr/local/etc/stunnel/stun nel.pid

Stunnel to the rescue
by Steven Sporen 23 Aug '04

23 Aug '04

Hi, Is it possible to configure STUNNEL to provide support for STARTTLS with IMAP (Microsoft Exchange Server doesn't support this) Have a look at RFC2595 http://www.faqs.org/rfcs/rfc2595.html The reason is - Symbian cell phones only allow secure IMAP via this method they can't connect to SIMAP. Please help Thanks

Charles, Check to see if you are being bitten by the "Eudora" problem -- add the following line to the top of your stunnel.conf file, and see if it magically starts working: options = DONT_INSERT_EMPTY_FRAGMENTS You can also see a related set of mails from myself, describing the problem we had.

I have tested it without stunnel and it checks fine as well. I keep getting the connection closed when I run through stunnel. I don't understand if something bad has actually happened i.e. from the error warnings. Is an "alert" a bad thing i.e. does it indicate that something is broken? Does stunnel normally close the connection after every message exchange?

Newbie: Keep getting connection closed
by Charles A. Monteiro 17 Aug '04

17 Aug '04

We are using a proprietary protocol over tcp/ip which works fine and has for a number of years. I have tested it without stunnel and it checks fine as well. I keep getting the connection closed when I run through stunnel. I don't understand if something bad has actually happened i.e. from the error warnings. Is an "alert" a bad thing i.e. does it indicate that something is broken? Does stunnel normally close the connection after every message exchange? I have included the logs for both the stunnel client and server as well as the respective conf files. thanks in advance, -Charles --------------------------------------- client log: 2004.08.17

SSL Handshake problems

I have a tunnel that forwards connections from syslog-ng on localhost to my loghost. Or rather, I don't.

_GET_CLIENT_HELLO:unknown protocol
by markzero＠logik.ath.cx 16 Aug '04

16 Aug '04

Hi. I'm so close to having a working loghost, with stunnel encrypted connections. Not close enough however. I have syslog-ng setup to log to 127.0.0.1:5515 on all clients. The client config: [syslogngs] accept = 127.0.0.1:5515 connect = 192.168.1.7:5514 On the loghost, stunnel listens on *.5514 and forwards to connection to 127.0.0.1:5515 (which syslog-ng is listening on). (server config): [syslogngs] accept = 192.168.1.7:5514 connect = 127.0.0.1:5515 I'm making an assumption that the certificates are working, as I'm using (or attempting to use) both client and server authentication. Watching the stream with a packet sniffer shows absolutely no connections between the client and the loghost. Strings such as this appear in the stunnel.log repeatedly: 2004.08.16 20:42:26 LOG7[7690:1006693376]: syslogngs started 2004.08.16 20:42:26 LOG5[7690:1006693376]: syslogngs connected from 127.0.0.1:2956 2004.08.16 20:42:26 LOG7[7690:1006693376]: SSL state (accept): before/accept initialization 2004.08.16 20:42:26 LOG7[7690:1006693376]: waitforsocket: FD=13, DIR=read 2004.08.16 20:42:26 LOG7[7690:1006690304]: syslogngs accepted FD=14 from 127.0.0.1:24856 2004.08.16 20:42:26 LOG7[7690:1006690304]: FD 14 in non-blocking mode 2004.08.16 20:42:26 LOG7[7690:1006763008]: syslogngs started 2004.08.16 20:42:26 LOG5[7690:1006763008]: syslogngs connected from 127.0.0.1:24856 2004.08.16 20:42:26 LOG7[7690:1006763008]: SSL state (accept): before/accept initialization 2004.08.16 20:42:26 LOG7[7690:1006763008]: waitforsocket: FD=14, DIR=read 2004.08.16 20:42:26 LOG7[7690:1006763008]: waitforsocket: ok 2004.08.16 20:42:26 LOG3[7690:1006763008]: SSL_accept: 140760FC: error:140760FC:SSL routines:SSL23_GET_CLIENT_HELLO:unknown protocol 2004.08.16 20:42:26 LOG7[7690:1006763008]: syslogngs finished (1 left) 2004.08.16 20:47:26 LOG7[7690:1006693376]: waitforsocket: timeout 2004.08.16 20:47:26 LOG7[7690:1006693376]: syslogngs finished (0 left) Have I made some glaring error that I'm not aware of? thanks mark
