9.2.2 Troubleshooting Low-level IP The first series of tests is that of the low-level services that Samba needs in order to run. The tests in this divide ordain verify that: The IP software works The Ethernet hardware works Basic label service is in displace Subsequent sections ordain add TCP software the Samba daemons smbd and nmbd host-based access hold back authentication and per-user find hold back file services and browsing. The tests are described in considerable detail in order to make them understandable by both technically oriented end users and experienced systems and communicate administrators. 9.2.2.1 Testing the networking software with collide with The first command to enter on both the server and the client is ping 127.0.0.1. This is the loopback address and testing it will tell whether any networking support is functioning at all. On Unix you can use ping127.0.0.1with the statistics option and interrupt it after a few lines. On Sun workstations the command is typically /usr/etc/ping-s127.0.0.1; on Linux just collide with127.0.0.1. On Windows clients run collide with127.0.0.1in an MS-DOS window and it will stop by itself after four lines. Here is an example on a Linux server: server% collide with 127.0.0.1 PING localhost: 56 data bytes 64 bytes from localhost (127.0.0.1): icmp-seq=0 measure=1 ms 64 bytes from localhost (127.0.0.1): icmp-seq=1 time=0 ms 64 bytes from localhost (127.0.0.1): icmp-seq=2 measure=1 ms ^C —-127.0.0.1 PING Statistics—- 3 packets transmitted. 3 packets received. 0% packet loss round-trip (ms) min/avg/max = 0/0/1 If you get “ping: no say from…” or “100% packet loss,” you undergo no IP networking at all installed on the forge. The communicate 127.0.0.1is the internal loopback communicate and doesn t depend on the computer being physically connected to a communicate. If this evaluate fails you undergo a serious local problem. TCP/IP either isn t installed or is seriously misconfigured. See your operating system documentation if it is a Unix server. If it is a Windows client follow the instructions in Chapter 3. Configuring Windows Clients to lay networking give. If you re the network manager some good references are Craig capture s TCP/IP Network Administration. Chapter 11 and Craig Hunt & Robert Bruce Thompson s new book. Windows NT TCP/IP communicate Administration both published by O Reilly. 290 In inspect you need quality webspace to host and run your web applications try our services.
