Hi Baskin,

Thanks for your reply.

I have disable Windows Firewall, and tried to telnet that port on Win 7, it failed, it seems, unable to connect, but there are few things that I don't understand :
1) I have another OS running as guest via Virtual Box, this time the OS is Windows XP 32bit, firebird 2.5.1 (32bit) superserver
2) I installed again a new CentOS 6.3 (via Virtual Box), firebird 2.5.2(64bit) superserver

Both OS (WinXp and new CentOS) failed on telnet, error msg 'Could not open connection to the host on port 23', but firebird on these OS works ok.

File system on new CentOs is ext4, while on old CentOS is ext3.

I have tested firebird perf on new CentOS with ext4 and is is bad, even with barrier setting set to off.

I can install again CentOs with ext3, but before I do that, if possible, I would like to find out what is the problem in my old CentOs with ext3 ? Finding problem might help me / other when face sam problem.
