gregmb -> hosts in /etc/hosts not resolved (Sep. 7, '06, 11:53:17 AM)
maybe this has been covered before but I haven't been able to find it. Interix 3.5 on Windows XP Pro I've install the main hotfixes for SFU Anyway, I have added IP/hostnames to /etc/hosts however when I try to 'ping "name"' I get the error that "name" is not found. for example /etc/hosts 172.16.0.10 lock1 ping lock1 ping: unknow host lock1 So what I'm I doing wrong? Thanks Greg

Is your /etc/hosts files still a symbolic link to the Windows hosts file? What I have is: /etc/hosts -> /dev/fs/C/WINDOWS/system32/drivers/etc/hosts

gregmb -> RE: hosts in /etc/hosts not resolved (Sep. 7, '06, 1:10:25 PM)
yes it's still a symbolic link. Greg

Do you have "lookup file bind" in /etc/resolv.conf?

gregmb -> RE: hosts in /etc/hosts not resolved (Sep. 7, '06, 1:48:09 PM)
Interesting, I had 'file bind lockup' I changed it to 'lookup file bind' with no effect, unless I neeed to reboot? Also the complete resolv.conf has the following: # search lookup file bind nameserver 10.190.213.196

The search line should have the domain that your machine is part of (e.g. "bird.com"). The /etc/resolv.conf doesn't actually have an effect on ping. Try commenting out the "nameserver" line and you'll see. (This is the ping that ships on the CD). The hostname lookup is a system call that in turn calls WinSock for resolution. It's really WinSock that needs to be reading the "hosts" file.

commenting out the nameserver had no effect. rsh also seems to have the same problem. The hostnames have no domain, they are on a private subnet (i.e. another NIC) and have simple names. These nodes/hostnames are embedded controllers, no way to alter their hostnames. rsh & ping work when you give the IP. So what do I need to do to get these names resolved? I've seen this work on other XP Pro / SFU 3.5 machines. Thanks Greg

> commenting out the nameserver had no effect. That's right. Because the ping on the CD uses the system call that uses WinSock which doesn't know anything about /etc/resolv.conf. > I've seen this work on other XP Pro / SFU 3.5 machines. Yeah, it works for me as long as the "...system32/drivers/etc/hosts" file is the one that gets changed. I don't need to reboot. So the file is regularly re-read by WinSock. You have /etc/hosts as the symlink so that should be fine. In the registry HKLM\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters the entry "DataBasePath": is it set to "%SystemRoot%\System32\drivers\etc" ?

Yes, that is what the register parameter is set to.

How about posting the results of the following commands: $ /bin/uname -X $ /bin/ls -l /etc/hosts $ /bin/cat /etc/hosts $ /bin/ls -l /bin/ping $ /bin/ping lock1 $ /usr/contrib/win32/bin/wping lock1 Maybe from this we can debug it for you.

I was just looking at when I got your post. I found the problem, the C:/WINDOWS/system32/drivers/etc/hosts file had odd permissions -r-xrwx--- 1 +Administrators +SYSTEM ....... hosts I changed it to -rwxrwxrwx , then ping and rsh started to resoled the names Can someone list what the owner ship and permissions of these files should be. The 'group' file appears to be owned not by Administrator but by a user account and group, hosts, passwd , etc. also seem to vary in permissions. So I not sure what is correct for them. Thanks Greg
