Hello, My network is composed of 2 PCs,on the first 1, I installed Linux redhat 9 with mysql , SER and DNS (ulfg1.lb), on the other one I installed winXP with User Ugent Sjphone and ethereal. I configured SER to work with mysql and I created a user named test using serctl. ( I am implementing all said in ser_howto.pdf) And I start ser : service ser start And ser starts successfully. with Sjphone I configured the proxy domain and the user domain to the domain ulfg1.lb, and i signed in with user test just created with serctl. And I examin the traffic with ethereal. SJphone tried to register the user test(a)ulfg1.lb but the response was error 483 (too many hops). Can someone helps me to resolve this problem. Best regards.
