Hello Genius,
when I used the demo_sftp.py to try the sftp connection ,some of my servers throw the following exception:
[root@sallic001 demos]# python demo_sftp.py 10.220.115.106
/usr/lib64/python2.4/site-packages/Crypto/Util/number.py:57: PowmInsecureWarning: Not using mpz_powm_sec. You should rebuild using libgmp >= 5 to avoid timing attack vulnerability.
_warn("Not using mpz_powm_sec. You should rebuild using libgmp >= 5 to avoid timing attack vulnerability.", PowmInsecureWarning)

but at the same time when I tried other servers(with same system version and etc.) ,they works ok ,
I don't what's wrong with it , you can look at the following sftp log for more debug informations ,
