[Bug 1945961] [NEW] mininet's pingall doesn't work correctly with iputils-ping and locale different to English
Public bug reported: $ lsb_release -a No LSB modules are available. Distributor ID: Ubuntu Description:Ubuntu 20.04.3 LTS Release:20.04 Codename: focal mininet version 2.2.2-5ubuntu1, but also tested with 2.3.0-1ubuntu1 from impish. mininet is not able to parse the ping output in a localised environment, for languages other than English. For example, this is running on fr_FR.UTF-8: $ sudo mn *** Creating network *** Adding controller *** Adding hosts: h1 h2 *** Adding switches: s1 *** Adding links: (h1, s1) (h2, s1) *** Configuring hosts h1 h2 *** Starting controller c0 *** Starting 1 switches s1 ... *** Starting CLI: mininet> pingall *** Ping: testing ping reachability h1 -> *** Error: could not parse ping output: PING 10.0.0.2 (10.0.0.2) 56(84) bytes of data. 64 octets de 10.0.0.2 : icmp_seq=1 ttl=64 temps=4.36 ms --- statistiques ping 10.0.0.2 --- 1 paquets transmis, 1 reçus, 0 % paquets perdus, temps 0 ms rtt min/avg/max/mdev = 4.355/4.355/4.355/0.000 ms X h2 -> *** Error: could not parse ping output: PING 10.0.0.1 (10.0.0.1) 56(84) bytes of data. 64 octets de 10.0.0.1 : icmp_seq=1 ttl=64 temps=0.978 ms --- statistiques ping 10.0.0.1 --- 1 paquets transmis, 1 reçus, 0 % paquets perdus, temps 0 ms rtt min/avg/max/mdev = 0.978/0.978/0.978/0.000 ms X *** Results: 100% dropped (0/2 received) I can workaround the problem with LANG=C: $ LANG=C sudo mn *** Creating network *** Adding controller *** Adding hosts: h1 h2 *** Adding switches: s1 *** Adding links: (h1, s1) (h2, s1) *** Configuring hosts h1 h2 *** Starting controller c0 *** Starting 1 switches s1 ... *** Starting CLI: mininet> pingall *** Ping: testing ping reachability h1 -> h2 h2 -> h1 *** Results: 0% dropped (2/2 received) Bug filed upstream: https://github.com/mininet/mininet/issues/1063 ** Affects: mininet (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1945961 Title: mininet's pingall doesn't work correctly with iputils-ping and locale different to English To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mininet/+bug/1945961/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
