check my bugreport with them http://bugs.distributed.net/show_bug.cgi?id=3649
I am running SuSE9.1/64bit for AMD64 on EPoX8KDA3+ with 3200+ cg-core. I have got several more AMD64 systems in my lab, but they are different in cpu core, chipset and SuSE version (9.0). The problem I see with the above isolated new system is that dnetc, beta for linux/amd64, cannot communicate with dnetc servers in the Internet; 32bit dnetc seems to run properly.
this is a known bug with suse 9.1 x86_64 due to different libraries etc...
Since all other amd64 based systems with SuSE9.0 run 64bit dnetc properly, I guess SuSE9.1 may cause some problems with respect to dnetc. I wonder if someone of you are running 64bit dnetc on SuSE9.1/amd64. I am happy, if I can collect information before getting in touch with distributed.net. Thanks for your attention.
