My home LAN network consist of three machines: 1. linux (Linux Mandrake 9.1) which connects to my ISP and it is router/gateway for my lan. IP (192.168.1.1) 2. solaris (Solaris 9 X86) (192.168.1.2) 3. windows (Windows XP) (192.168.1.3) linux and windows are working good, but My Solaris box can't see/ping other machines, and others can't ping solaris. The system can ping itself. #ping 127.0.0.1 127.0.0.1 is alive #ping localhost localhost is alive #ping 192.168.1.2 192.168.1.2 is alive #ping solaris solaris is alive Here is how I have configured my solaris box. /etc/hosts 127.0.0.1 localhost loghost 192.168.1.1 linux linux.calmadow.com 192.168.1.2 solaris solaris.calmadow.com 192.168.1.3 windows windows.calmadow.com /etc/hostname.elxl0 solaris /etc/netmasks 192.168.1.0 255.255.255.0 /etc/resolv.conf domain my_isp.domain.com nameserver 24.153.23.66 nameserver 24.153.22.195 /etc/defaultrouter 192.168.1.1 The output of the "ifconfig -a ", "netstate -nr", and "arp -a" commands are as follows: #ifconfig -a lo0: flags=1000849 mtu 8232 index 1 inet 127.0.0.1 netmask ff000000 elxl0 : flags=1000843 mtu 1500 index 2 inet 192.168.1.2 netmask ffffff00 broadcast 192.168.1.255 ether 0:a0:24:df:a8:fa #netstate -nr destination gateway flags ref use interface 192.168.1.0 192.168.1.2 U 1 34 elxl0 224.0.0.0 192.168.1.2 U 1 0 elxl0 default 192.168.1.1 UG 1 0 127.0.0.1 127.0.0.1 UG 23 lo0 #arp -a device IP Mask flags physical Addr elxl0 solaris 255.255.255.255 sp elxl0 224.0.0.0 240.0.0.0 sm I don't see the default route in the "arp -a" output, I don't understand what 224.0.0.0 is Actually It is my first time I install solaris/unix and I have no experience of Solaris/Unix, but I have been using linux for 1 year. I have spent for the last 30 hours searching on GOOGLE, but all in vain. I would be very happy if some one tell what I have done wrong or If I have to change something. NOTE: When I ping from windows to linux or linux to windows only the corresponding two lights of the hub is flushing, but if I ping from solaris to windows/linux or windows/linux to solaris all three lights are flushing and I see the following line in the linux's /var/log/message Jul 7 23:25:13 linux rwhod[22253]: sendto(192.168.1.255): Operation not permitted Please help Thanks in advance

have you troubleshoot this problem at the physical lvl.... ie. changed cables and plug to other ports in the hub...

Yes I did all those things but nothing worked. I have posted this message to sun forum, and someone replyed the following message. I disabled the OS'a plug & play in the BIOS, and It works!! --------------------- This could be a problem with the NIC not receiving interrupts. A possible solution is contained in reply #5, here: http://forum.sun.com/thread.jsp?forum=11&thread=14244 I think the root cause is described here: http://forum.sun.com/thread.jsp?forum=11&thread=8921 I've not yet tested it, but patch 114324-03 "SunOS 5.9_x86: pcplusmp Patch" might fix this issue. --------------------------- thanks mark

You need the Computer`s BIOS ACPI disable

I had this same problem with the Sparc version. I could ping localhost, hostname, and ip but I couldn’t ping any other computer on the network. Turns out it was a duplex / speed miss match. I had to manual set the duplex and speed of the network card. If you are getting Link Down: Check Cable errors or something like that I’ll bet it’s the same problem I had. I don’t remember off hand how to set the speed and duplex, maybe someone else can post that. I know you can do a search on google and find the answer.

I had this same problem with the Solaris 9 for x86. It only can ping itself.It can't ping other computer.And if I set IPaddress, I can't inter the Xwindow. Disable the OS's plug & play in the BIOS,it will be ok,will it? And how I disable the OS's plug & play in the BIOS?
