From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.0.0) Gecko/20020529 Description of problem: Dialup USB modem connection, manual wvdial, manual copy of DNS from /var/log/messages to Network Configuration DNS tab [see bug 98786, bug 98790]. I can ping by name, surf (http), ssh, receive mail (POP3) in Evolution, but sending mail via SMTP from Evolution gets "Could not connect to <smtp_hostname> port 25: no route to host." Version-Release number of selected component (if applicable): ppp-2.4.1-10 How reproducible: Always Steps to Reproduce: 1.Configure USB modem connection, requesting auto IP and auto DNS. Manual wvdial to workaround bug 98786. Manually forward DNS server settings from /var/log/messages to Network Configuration DNS tab to workaround bug 98790. 2.Try to send mail using SMTP from Evolution. 3. Actual Results: "Could not connect to <smtp_host> port 25: No route to host" Expected Results: No complaints sending mail. Additional info: -----netstat -r Kernel IP routing table Destination Gateway Genmask Flags MSS Window irtt Iface nas12.bellevue1 * 255.255.255.255 UH 0 0 0 ppp0 169.254.0.0 * 255.255.0.0 U 0 0 0 lo 127.0.0.0 * 255.0.0.0 U 0 0 0 lo default nas12.bellevue1 0.0.0.0 UG 0 0 0 ppp0 ----- -----ps ax | grep ppp 2984 ?

The correct citations are bug 98781 failed to activate ppp0 with eror 28 [workaround: manual wvdial] bug 98786 auto DNS ignored [workaround: manual copy from /var/log/messages to Network Configure > DNS tab] [Sorry; my list got skewed while I was trying to be precise.]
Please verify this with a newer version of Red Hat Enterprise Linux or Fedora Core and reopen it against the new version if it still occurs. Closing as "not a bug" for now.
