changing line on a file
Hi, I want to change on a file this line:
vif = [ 'ip=167.112.194.243,mac=00:16:3E:CE:23:14' ]
into:
vif = [ 'ip=167.112.194.243,mac=00:16:3E:CE:23:14,vifname=veth216','ip=10.1.1.1,mac=00:16:3E:FD:58:BB,vifnam e=veth216a']
But there are some conditionals:
1. last part '] of the original line after 00:16:3E:CE:23:14' ] may vary to 00:16:3E:CE:23:14' ] or 00:16:3E:CE:23:14 ' ]
2. The second mac adrress of the line I need, 00:16:3E:FD:58:BB, must be different every time I run sed. Maybe just changing the last two characters BB to other two characters.
3. The [ ' and ' ] of both lines could be separated by some espaces, example [ ' or [' or ' ] or '] so you should not take this characters as a reference.
4. The Ip 167.xx.xx.xx and first mac address 00:16:3E:CE:23:14 are the same in two line. The second ip always is 10.1.1.1, and the second mac address must change every time I run sed command.
thanks tons
regards,
Israel.

xvif
XVIF(4) BSD/xen Kernel Interfaces Manual XVIF(4) NAME
xvif -- Xen backend paravirtualized network interface SYNOPSIS
pseudo-device xvif DESCRIPTION
The xvif interface forms the backend part of the paravirtualized drivers used by Xen domains to offer network connectivity. When the guest domain is NetBSD, the endpoint of the xvif interface is a xennet(4) interface. In the XenStore, xvif and xennet are identi- fied by ``vif'' (virtual interface) entries. All xvif interfaces follow the ``xvifXiY'' naming convention, where 'X' represents the guest domain identifier, and 'Y' an arbitrary identi- fier; most of the time, it is the frontend interface identifier, e.g. ``xennetY''. For convenience, the MAC address of an xvif interface is chosen by incrementing the third byte of the MAC address of the frontend device. Conceptually, frontends and backends drivers are similar to two Ethernet cards connected via a crossover cable. DIAGNOSTICS
xvif%di%d: can't read %s/mac: %d The MAC address for this interface could not be read from XenStore. xvif%di%d: %s is not a valid mac address The MAC address specified in the configuration file of the newly created guest domain is invalid. xvif%di%d: Ethernet address %s MAC address of the xvif interface. SEE ALSO
ifmedia(4), xennet(4), ifconfig(8) HISTORY
The xvif driver first appeared in NetBSD 4.0. AUTHORS
The xvif driver was written by Manuel Bouyer <bouyer@NetBSD.org>. BSD
