Any ipalias values set in Linuxconf have no effect.

This patch makes aliases work provided that, in linuxconf, you:
(a) specify only one IP address (not hostname) per line
(b) include an explicit netmask for each alias on the next line

Note that the broadcast address will be bogus if you are not
classful but, for aliases, this seldom matters.

This is obviously only intended as a quick workaround until
RedHat can provide a comprehensive solution.

This is fixed in initscripts-4.53-1, which is in the current Raw Hide
release. It currently is relying on the fact that linuxconf
does *not* write a "DEVICE" field to parse the files properly.

Please re-open if this doesn't work for you.

What does ifcfg-eth0:0 look like?

------- Additional Comments From alan  10/15/99 18:59 -------
Here is some script output indicative of the problem.  If you scan
through it you will notice that nowhere does the DEVICE variable ever
get set.  This, in turn, causes the DEVICETYPE and REALDEVICE
variables to be null..... resulting chaos insues.

------- Additional Comments From webguy  10/15/99 21:57 -------
Had the same problem. ifcfg-eth0:0 says:

IPADDR="10.200.7.44"
NETMASK="255.255.0.0"

*** Bug 6069 has been marked as a duplicate of this bug. ***

If you use linuxconf/config/networking/server tasks/IP
aliases for virutal hosts the virtual hosts do not work.
linuxconf makes some files in
/etc/sysconfig/network-scripts like ifcfg-eth0:? and if you
try and run ifup-aliases you get errors like the following:

ipseen_130_37_129_65-74=ifcfg-eth0:0: command not found
ifup-aliases: error in ifcfg-eth0:0: already seen ipaddr\
   130.37.129.65-74 in -74

The ifup-aliases script has some documentation regarding
IPADDR_START, IPADDR_END, but the files created by linuxconf
don't seem to follow this and use IPADDR.

If you undo some of the debugging comments in ifup-aliases,
the device (in the script as $DEVICE) does not appear to be
defined correctly. But, if you change it to $device, other
parts seem not to work.

*** Bug 6162 has been marked as a duplicate of this bug. ***

The following is an error with the ifup-aliases script in
/etc/sysconfig/network-scripts

If I add an ip range in ifcfg-eth0:0 like x.x.x.90-100, the
following happens error shows up in /var/log/messages:

ifup-aliases: /etc/sysconfig/network-scripts/ifup-aliases:
ipseen_x_x_x_90-100=ifcfg-eth0:0: command not found
ifup-aliases: error in ifcfg-eth0:0: already seen ipaddr
x.x.x.90-100 in -100

This worked in RedHat 6.0. I got around the problem by
replacing the ifup-aliases script in 6.1 with the script in
6.0, and it worked...

*** Bug 6777 has been marked as a duplicate of this bug. ***

After installing redhat 6.1 on one of our web servers we
noticed that it was not responding to requests correctly,
after checking, the ip aliases for our server had not been
initialized.  A clean install on another system produced the
same effect (after configuring the aliases using
linuxconf).  The quick solution for us was to copy
ifup-aliases from the package that came with 6.0 (this fixed
both machines)

I checked to see if this had been submitted as a bug, and it
doesn't seem so... which is kind of surprising... hopefully
I'm not bothering you all with something that has already
been brought up.

------- Additional Comments From mlewis  11/06/99 11:20 -------
nevermind, after searching on initscripts instead of ipup-aliases I
found the old bug report... sorry

*** Bug 6825 has been marked as a duplicate of this bug. ***

I noticed your name in the new 6.1 ifup-aliases script.  I
had problems bring up virtual interfaces and with a little
bugging noticed that the following line seemed to be
missing.

	DEVICE="`echo $FILE | sed -e 's/ifcfg\-//'`"

I placed this line in the function new_interface().  Just
below the assignment line that starts with IPGLOP and above
line that starts wtih DEVNUM.  Around line 133 in the file.

I am not sure if this is where you intended the assignment
to be made, but it seems to work correctly.

I added the line because at line 156 with the compare of

      if [ -z "$DEVICE" -o -z "$IPADDR" ]; then
      	echo "error in $FILE: didn't specify device or
ipaddr" >&2 ; exit 0
      fi

$DEVICE is empty and causes script to fail.

Sorry about the strange context, I send this also in an email to Bill
Nottingham who is in the header of the file as the last person to
modify ifup-aliases.

This is still not fixed in the latest tree.

Or rather, eth0:0 is indeed brought up but linuxconf cannot edit its
configuration.

Then it's no longer an initscripts problem, but a linuxconf problem.

Closing since we don't ship linuxconf anymore.
