netboot fun with a U10
in [Solaris]
|
From: Mauricio Tavares on 20 Apr 2005 10:45 Ok, I am getting vewy pissed here with a certain Sun U10. So, I set my U30/Solaris 9 box to be a rarpd/tftpd server, first making sure the /etc/inted.conf has tftpd enabled and pointing to the right directory: tftp dgram udp6 wait root /usr/sbin/in.tftpd in.tftpd -s /tftpboot /etc/ethers has the proper machine name and IP: # cat /etc/ethers 08:00:20:ff:ec:30 ficus # I then download the debian tftpboot.img for sun4u and set it up in /tftpboot (remember the ip for the U10 is 159.178.77.187. I used bc to find out the hex values): # ln -s debian-3.0-ultra-tftpboot.img 9FB24DBB.SUN4U # Then, I start the rarpd in debugging mode to see what is happening and reboot the U10: # /usr/sbin/in.rarpd -d -a /usr/sbin/in.rarpd:[1] device hme0 ethernetaddress 8:0:20:8a:3b:6d /usr/sbin/in.rarpd:[1] device hme0 address 159.178.77.196 /usr/sbin/in.rarpd:[1] device hme0 subnet mask 255.255.0.0 /usr/sbin/in.rarpd:[3] starting rarp service on device hme0 address 8:0:20:8a:3b:6d /usr/sbin/in.rarpd:[3] RARP_REQUEST for 8:0:20:ff:ec:30 /usr/sbin/in.rarpd:[3] trying physical netnum 159.178.0.0 mask ffff0000 /usr/sbin/in.rarpd:[3] good lookup, maps to 159.178.77.187 /usr/sbin/in.rarpd:[3] immediate reply sent and that is where it sits. On the U10's console, we have: Sun Ultra 5/10 UPA/PCI (UltraSPARC-IIi 440MHz), No Keyboard OpenBoot 3.25, 256 MB (50 ns) memory installed, Serial #16772144. Ethernet address 8:0:20:ff:ec:30, Host ID: 80ffec30. Bad magic number in disk label Can't open disk label package Bad magic number in disk label Can't open disk label package Bad magic number in disk label Can't open disk label package Boot device: net File and args: and that is as far as it goes. I check if tftp is running, # ps -ef | grep tftp nobody 2733 2732 0 10:02:54 ? 0:00 in.tftpd -s /tftpboot root 2732 178 0 10:02:54 ? 0:00 in.tftpd -s /tftpboot root 2971 2539 0 10:34:01 pts/6 0:00 grep tftp # Out of frustration, I read the netbsd document on installing on a sparc box, http://tinyurl.com/as24k, and try to force the server to map my client's ethernet address to its IP address: # arp -s ficus 8:0:20:ff:ec:30 # And then restarted rarpd, but still have no results. What is going on here? Why is it not retrieving the image as provided by tftp? -- Mauricio raub-kudria-com (if you need to email me, use this address =)

You might see some tftp errors being returned, or maybe not the file(s) you were expecting. -- Andrew Gabriel

Tried their suggestion (chmod 755 on the original file) and restarted rarpd in debug mode (again). Same result. =( So, I went to another of our Sun boxes (An U1. Gasp!) in the same room and subnet: mauricio(a)papaya-16>tftp poisonivy tftp> get 9FB24DBB.SUN4U Received 4626800 bytes in 11.1 seconds tftp> mauricio(a)papaya-17> =( -- Mauricio raub-kudria-com (if you need to email me, use this address =)

Your first message said: # ln -s debian-3.0-ultra-tftpboot.img 9FB24DBB.SUN4U > I ran snoop as you suggested and it is giving a TFTP Error: access > violation message: > # snoop -d hme0 ether 8:0:20:ff:ec:30 > Using device /dev/hme (promiscuous mode) > poisonivy.biostat.ufl.edu -> ficus.biostat.ufl.edu UDP D=41993 S=38680 > LEN=30 > ficus.biostat.ufl.edu -> BROADCAST TFTP Read "9FB24DBB" (octet) > poisonivy.biostat.ufl.edu -> ficus.biostat.ufl.edu TFTP Error: access > violation But there's the the file it's looking for. You should also link that file to 9FB24DBB (no .SUN4U extension). > mauricio(a)papaya-16>tftp poisonivy > tftp> get 9FB24DBB.SUN4U Note the filename... > Received 4626800 bytes in 11.1 seconds > tftp> mauricio(a)papaya-17> > =( -- Darren Dunham ddunham(a)taos.com Senior Technical Consultant TAOS http://www.taos.com/ Got some Dr Pepper?
