Problem > In a Vmware environment, running {{test_network_acl}} we examined why it was > failing, it was discovered an issue on {{VmwareResource}}: > {code:title=VmwareResource.java|borderStyle=solid} > private int findRouterEthDeviceIndex(String domrName, String routerIp, String > mac) throws Exception { > VmwareManager mgr = > getServiceContext().getStockObject(VmwareManager.CONTEXT_STOCK_NAME); > s_logger.info("findRouterEthDeviceIndex. mac: " + mac); > // TODO : this is a temporary very inefficient solution, will > refactor it later > Pair<Boolean, String> result = SshHelper.sshExecute(routerIp, > DefaultDomRSshPort, "root", mgr.getSystemVMKeyFile(), null, "ls > /proc/sys/net/ipv4/conf"); > {code} > Command sent to router returned a pair which its first parameter was always > true but second parameter sometimes it was null and sometimes the correct > output for given command. > h2. Solution > Examining {{SshHelper}} we discovered that cases in which second parameter in > result was null, didn't consume stdout properly -- This message was sent by Atlassian JIRA (v6.3.4#6332)
