I have redhat 9 and have install python-optik-1.4-2 but still seem to be
getting
[root at serv1 boot]# ./rtpproxy.other start
Starting RTP Proxy server: rtpproxyTraceback (most recent call last):
File "/usr/local/etc/ser/rtpproxy/rtpproxy.py", line 22, in ?
from optparse import OptionParser, Option, OptionValueError
ImportError: No module named optparse
.
Any suggestions?
Thanks
