delaying eth0 initialization?
Last modified: 2008-05-01 11:37:48 EDT
I have been having intermitent problems with multiple NIC's some times they both work or the second one doesnt. I have avoided these problems by putting the network config's in the /etc/rc.d/rc.local i.e. modprobe io=xxx irq=x ifconfig and all that jazz. I am still not satisfied with this and would like to know why it does delay the ethx initialization. How long does it delay anyway? well we all know that it does'nt if it doesnt start at boot. just look at the ifup script in /sbin/ifup. I dont use X on most of the machines that I install linux on, and I like to use linuxconf but it is kinda buggy with multiple cards. i.e. it makes multiple copies of the same setup and enabling them. Is there a problem with linuxconf? I also looked at /sbin/ifup and noticed that it has a variable "if uid !=0 then "delaying {DEVICE} initialization" is this what the problem is? I mostly configure servers with two nics after installing i.e. I install one card during setup then hand edit the second one in /etc/sysconfig/network-scripts/ifcfg-ethx. This is not exceptable for a server platform to just default to one NIC during install. anyway that is what the problem is. Regards, Rayw rayw@advanced-computer.com.
Delaying eth initialization is usually associated with the modules not knowing that there are two eth cards in the system. The easiest way to set this up is to place in your /etc/conf.modules file alias eth0 <network module> alias eth1 <network module> and then if the cards are the same then add the following: options <network module> io=0x300,0x280 or whatever address the cards are using. If Linuxconf has problems configuring network interfaces then we need to have bug reports specifically for linuxconf so we can fix problems associated with it. We are continuously trying to improve functionality of linuxconf. The reason for the ifup script to contain the if uid != 0 part, is so that if the root user configures it that way, normal users can bring up or down interfaces. The line USERCTL=yes/no in /etc/sysconfig/network-scripts/ifcfg-eth0 dictates this. If the ONBOOT= is set to yes then when you boot the machine the uid does not matter. ------- Email Received From Raymond Willis <rayw@infinity-technical.com> 01/21/99 10:15 -------
