Trying 69.64.46.7...

-> other adress does not work ...

-bash-3.00# telnet 69.64.46.7 80
Trying 69.64.46.7...
Connected to 69.64.46.7.
Escape character is '^]'.
-bash-3.00# telnet 69.64.46.7 443
Trying 69.64.46.7...
Connected to 69.64.46.7.

Hello,

Are the versions of telnet in VE and on HN the same?
Can you post here straces of telnet to 25th port from VE and
from HN, please.

Thanks!
vass.

Please, don't run strace with "-e trace=file" option.
Do "strace -f command".

To check what versions are on your machine and in VE:
"rpm -qa | grep telnet"

If it is possible for you, you can give me an access to the node
and I'll see what's wrong.

Thanks!

Sorry,
are you sure that strace from VE is complete?
You mentioned that telnet outputs "other adress does not work",
But in strace I can't find where it does it.
Moreover strace is ended by fstat64(), this is rather strange...

Thanks.
