[Serusers] "nat_uac_test" - missing modules when starting SER?

[Marty Chen]

hi klaus,

first, thx for helping out.
i am running the "ser-0.8.12-0.i386.rpm" version of SER on redhat 9 released
by iptel.org

i am a newbie in linux.... so if u could instruct me on how to locate the
nathelper module then perhaps i can find out the more about the version in
detail.

best regards,

which version of ser do you use? It's for sure in unstable and stable
from cvs.
