On Unix and Linux systems, the su command is used to assume the identity of another user, typically root. Since the root account is normally disabled on Mac OS X systems, su will not work. As an alternative to enabling the root account, you can use sudo to run individual commands as root, one at a time. If you need a root shell, you can get one by running sudo -s. The sudo command requires an administrator password.

I was able to resolve the problem by putting a small 5-port hub between the switch and the Wii. Everything worked fine then, but I don't know why that worked. I thought there might a problem with autonegotiation of the duplex and speed settings, but on the switch side I tried all possible settings for the duplex setting, i.e. auto, full, and half, with all possible combinations of the speed setting, i.e. auto, 100 Mbs, 10 Mbs, but none of the nine combinations worked.

When I did get the Wii's Internet connectivity working, I captured the traffic from/to it, so I would have a better idea of how it determines whether it has Internet connectivity. I've recorded my notes here.

When I checked the contents of /var/log, I found the following:

# ls -l

-rwxrwxrwx   1 root     other        240 Jul 27  2000 sysidconfig.log

I moved authlog, maillog, and sshd.log to a a directory under /home, recreated the files in /var/log with touch, set the permissions to 600, and changed the group to what it had been previously on authlog.

# touch authlog.log
# touch maillog.log
# touch sshd.log
# chmod 600 authlog
# chmod 600 maillog
# chmod 600 sshdlog
# chgrp sys authlog
# ls -l

-rw-------   1 root     sys            0 Aug 12 15:52 authlog

-rwxrwxrwx   1 root     other        240 Jul 27  2000 sysidconfig.log

I then restarted the syslog daemon so it would use the new files.

# /etc/init.d/syslog stop
# /etc/init.d/syslog start
syslog service starting.

When I then checked the free space for /var, 94% of the capacity was used, whereas it had been 100% previously.

Since Mozilla Firefox understands how to use SOCKS proxies, you can configure it to go through the SOCKS proxy. You can configure it to use a SOCKS proxy by clicking on Edit, then Preferences, and then the Network tab. Click on Settings and then select Manual proxy configuration. For a SOCKS proxy, put the address of the SOCKS proxy server in the SOCKS Host field and the port that is being used on that server in the Port field.

If I establish a SOCKS proxy server using the ssh command, e.g. ssh -D 8055 jdoe@192.168.1.1, then I'm tunneling connections to the SOCKS proxy through the encrypted SSH connection and I will use 127.0.0.1 in the SOCKS host field and 8055 in the Port field, rather than the default SOCKS proxy port of 1080.

After downloading the proxychains package with Mozilla Firefox, aka iceweasel, I used dpkg to install it.

root@Knoppix:/home/knoppix# dpkg --install proxychains_2.1-5_i386.deb 
Selecting previously deselected package proxychains.
(Reading database ... 0 files and directories currently installed.)
Unpacking proxychains (from proxychains_2.1-5_i386.deb) ...
dpkg: dependency problems prevent configuration of proxychains:

  Package libc6 is not installed.
dpkg: error processing proxychains (--install):
 dependency problems - leaving unconfigured
Errors were encountered while processing:
 proxychains

Proxychains looks for its configuration file in the following order:

1. ./proxychains.conf
2. $(HOME)/.proxychains/proxychains.conf
3. /etc/proxychains.conf

I copied the sample file /etc/proxychains.conf.dpkg-new to /etc/proxychains.conf.

root@Knoppix:/home/knoppix# cp /etc/proxychains.conf.dpkg-new /etc/proxychains.conf

The following default information appears in that file:

# ProxyList format
#       type  host  port [user pass]
#       (values separated by 'tab' or 'blank')
#
#
#        Examples:
#
#               socks5  192.168.67.78   1080    lamer  secret
#               http    192.168.89.3    8080    justu   hidden
#               socks4  192.168.1.49    1080
#               http    192.168.39.93   8080    
#               
#
#       proxy types: http, socks4, socks5
#        ( auth types supported: "basic"-http  "user/pass"-socks )
#
http    10.0.0.5 3128
http    10.0.0.3 3128
http    10.0.0.5 3128
#socks5 192.168.1.4 1080
#socks4 10.5.81.143 1080
#http   192.168.203.18 8080

I commented out the http lines with the 10.0.0.5 address by placing a "#" at the beginning of the line. I then removed the "#" from the socks5 line and changed the address from 192.168.1.4 to 127.0.0.1, since I was establishing a socks proxy using the ssh command. I changed the port from the default SOCKS port of 1080 to the one I used when I established the SOCKS proxy with ssh -D 8055 jdoe@192.68.1.1, i.e. port 8055. I then had the following lines in proxychains.conf.

# http  10.0.0.5 3128
# http  10.0.0.3 3128
# http  10.0.0.5 3128
socks5 127.0.0.1 8055
#socks4 10.5.81.143 1080
#http   192.168.203.18 8080

I also commented out "random_chain" and "chain_len" and uncommented "strict_chain".

I was then able to use proxychains with gpg to import a public key for a package repository into the public keyring for the root account.

root@Knoppix:/home/knoppix# proxychains gpg --keyserver wwwkeys.eu.pgp.net --rec
v-keys 9AA38DCD55BE302B
gpg: requesting key 55BE302B from hkp server wwwkeys.eu.pgp.net

gpg: no ultimately trusted keys found
gpg: Total number processed: 1
gpg:               imported: 1  (RSA: 1)

I was also able to use proxychains for apt-get update by using proxychains apt-get update.

To use the rescue CD, boot the system from the CD. You may need to configure the system's Basic Input Output System (BIOS) to attempt to boot from a CD before attempting to boot from the hard drive or hit a key that allows you to select the drive from which you want to boot. When you system starts booting from the CD, you will see an initial startup nenu.

Start knoppix in English (US)
Start knoppix in French
Start knoppix in console mode
Memory test
Boot from first hard disk

You must hit Enter when the menu appears or move the cursor up or down or the system will be booted from the hard drive rather than the boot process continuing from the CD.

Click on the image to enlarge it

During the boot process, the virus definitions will be updated, if the system has an Internet connection. If the software has a problem updating the definitions it will hang for awhile at the stage where it tries to update the virus definitions and then you will see the message "Trying to update BitDefender-scanner...fail..check your network ?" When the BitDefender Rescue CD completes booting, you will have a Graphical User Interface (GUI). A BitDefender AntiVirus Scanner for Unices program will start automatically and start scanning the hard drive in the system.

By default, all partitions detected on the hard drive will be scanned. When the scan completes, you'll have to choose what actions to take on the infected file(s). You can choose one action for all files or select an action for each item.

If you right-click somewhere on the desktop, you will see a list of applications on the CD. You can get a terminal window by selecting Terminal or Terminal (as root) by selecting from the menu that appears when you right-click on the desktop. Don't pick Exit from this menu, until you are ready to shut down the system. I.e., wait until the scan has completed and you've chosen what to do with any infected files detected
