Apologies for the cross-posting to CentOS list (already mailed to OpenVPNlist)..

am using OpenVPN [ http://openvpn.sf.net ] on CentOS 3.4 and having some issues.. it may possibly be an OpenVPN issue, but thought if anyone on this list is using or had any similar issues or have any thoughts..

below is my original posting with the issue I have been having.. couple of updates (alas, I still have the problem/issue)..please help..anyone..anyone..thanx

1. rebuilt the CentOS box/applied latest patches..(clone of RHES 3.0)

2. snagged 2.0 rc7 openvpn and compiled (this time pointing to already centos installed openssl RPMs/files) http://sourceforge.net/mailarchive/forum.php?thread_id=6328352&forum_id=... this time, I even generated the server certs on CentOS itself..

3. same issue, OpenVPN doesn't respond aftrer in production for a day..I don't see any log activity that stands out..note, I am using TCP instead of UDP..

4. only reboot is fixing this issue..

5. anyone successfully using OpenVPN on RedhatEnterprise 3.x or any clones of it with out any issue? TIA

====my original posting to the list=====

Greetings folks,

env: 1. servers on OVPN 2.0 rc6 on FC3 and CentOS 3.3(clone of RHES 3.0 with updt3), with all latest updates..Clients are all XP SP2. using TUN on servers/clients.. 2. using in routed config, custom certs all generated on FC3 and copied/replicated on to centos box. 3. use diff ip/netwok for "server" (in server config file) directive for obvious reasons..both OVPN servers are serving the same corp/office network.. 4. using TCP instead of UDP. 5. same setof "iptables" firewall rulesets..

here is the strange thing..

OVPN on FC3 seems to work with out any issues, but the one on CentOS box does not respond, after in production for a while..I have to reboot for it to start responding..my verbose logs don't show anything..it's like, there is not even a connection being established..I have ruled out network issues etc.. external IP's on both hosts are valid and accessable, while OpenVPN on 443 port gets hung or doesn't respond on CentOS host...(i run it on TCP 443)...

am getting a little tired of rebooting centos box. i guess I could cron the reboot, but I would like to find the root cause..anyone seen this issue? TIA ============================
