Description

I used 2.0.9 on OpenSolaris? 2009.06. It worked well. But, 2.1.3 did not work well.
The configuration is the following.

openvpn --daemon --config server.conf
--
dev tun
proto udp
server 10.8.0.0 255.255.255.0

client-to-client
push "redirect-gateway def1"

ca /etc/openvpn/keys/ca.crt
cert /etc/openvpn/keys/server.crt
key /etc/openvpn/keys/server.key
dh /etc/openvpn/keys/dh1024.pem

comp-lzo
persist-key
persist-tun
keepalive 10 120

ifconfig-pool-persist ipp.txt
status openvpn-status.log
log-append /var/log/openvpn/openvpn.log
--

With daemon mode, tun device have been closed and routing have been deleted at once at starting. And, clients can connect, but can't send/receive packets. Output logs are the following.

--

I found openvpn_exit() is called after fork in misc.c. And, tun_abort() is called in openvpn_exit function, thus tun device is closed.

I modified error.c as follows.

$ diff error.c.orig error.c
698c698,699
< tun_abort();
---

if (status == OPENVPN_EXIT_STATUS_ERROR)
tun_abort();

After that, it seemed to work well.
Clients can connect, and can send/receive packets.

This bug report is very old. Can someobdy reproduce this with a recent OpenVPN/Solaris version?
