[Bug 616706] New: Yast Printer Connection Wizard requires ICMP echo to be open when adding a network printer when it should only require that the TCP port the printer is listening on be open.
http://bugzilla.novell.com/show_bug.cgi?id=616706 http://bugzilla.novell.com/show_bug.cgi?id=616706#c0 Summary: Yast Printer Connection Wizard requires ICMP echo to be open when adding a network printer when it should only require that the TCP port the printer is listening on be open. Classification: openSUSE Product: openSUSE 11.2 Version: Final Platform: i586 OS/Version: openSUSE 11.2 Status: NEW Severity: Normal Priority: P5 - None Component: YaST2 AssignedTo: bnc-team-screening@forge.provo.novell.com ReportedBy: chris@ia.gov QAContact: jsrain@novell.com Found By: --- Blocker: --- User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.1.9) Gecko/20100317 SUSE/3.5.9-0.1.1 Firefox/3.5.9 When adding a printer via the Yast Printer Connection wizard and selecting TCP as the connection method, adding a printer fails even if the specified tcp port is open and reachable, if ICMP echo is not also allowed. ICMP echo should not be a requirement for adding a remote printer. A simple tcp ping on the specified port should be good enough, syn, syn/ack, ack. Reproducible: Always Steps to Reproduce: 1.Add a printer from Yast. 2.Choose the connection Wizard 3.Choose TCP and fill in the blanks with the destination being a printer in a network that the client does not have ICMP echo open to. (remote printer is Firewalled, access listed, etc...) 4.Test the connection. Actual Results: Observed with TCP dump that the connection wizard was attempting ICMP echo to the printer ip address and then failing without ever attempting a tcp connection on the port specified. (Telnet from console on the tcp port to the printer works fine) Expected Results: Connection wizard should not rely on ICMP echo to check the availability of a device. A connection to the actual TCP port specified should instead be attempted.

Just ignore the test result and proceed. yast2-printer runs the script /usr/lib/YaST2/bin/test_remote_socket to test this kind of connection which does basically those tests: 1. ping IP 2. netcat IP port If ping (which does ICMP echo) fails, there is an error message (use the [Details] button to get in in the YaST GUI) like this: --------------------------------------------------------------------- PING 10.11.12.13 (10.11.12.13) 56(84) bytes of data. --- 10.11.12.13 ping statistics --- 2 packets transmitted, 0 received, 100% packet loss, time 999ms Host 10.11.12.13 unreachable (network issue or firewall active?) --------------------------------------------------------------------- If netcat fails, there is an error message like this: --------------------------------------------------------------------- No connection possible to port 65000 on host 10.10.11.92 (wrong port or firewall active there?) --------------------------------------------------------------------- The connection test is just a basic connection test. To test whether or not the whole print queue (connection plus driver) really works, you have to print a test page. If you run a firewall, the messages already show you why the test may have failed in your particular case. I will not remove the initial ping test because I like to distinguish whether or not the IP is accessible via "ping IP" and afterwards whether or not the particular port on this IP is accessible (via "netcat IP port"). It works as intended and therefore the bug report is invalid. -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
