I have the same problem with c35b2 on my Red Hat Enterprise Linux Desktop (v. 5 for 64-bit x86_64):
gethostbyname>hostname problem: check /etc/hosts or /etc/resolv.conf
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1 localhost.localdomain localhost
::1 localhost6.localdomain6 localhost6
; generated by /sbin/dhclient-script
Any suggestion will be appreciated.
