The code introduced in November should limit it to just the last one (I think you need to delete the others manually...).

Did that get into 4.1.2? I recently deleted all the backups, and already have 11 new ones.

It should have been, so either I missed one place where it creates a backup, or you have an old version of rc.network in your pup_save...

Huh, it turned out I did have one in /initrd/pup_rw/etc/rc.d; don't know why. However according to "diff" it was identical to the one in /initrd/pup_ro2/etc/rc.d. Anyway I renamed the one in the pupsave and rebooted. That didn't add any new resolv.conf's. We'll see...

/etc/resolv.conf |
|
How many backups of /etc/resolv.conf should be kept?
None.
Backups of /etc/resolv.conf are just a waste of space in a production environment.
This code should be commented out, in a release version.
When should /etc/resolv.conf be cleared?
Never.
An empty /etc/resolv.conf always produces a 99% useless network.
The Internet works on IP addresses not host names.
Before your machine can open a connection to a server, it needs to find the IP address of that server. It does this by sending a query to a nameserver. To find the IP address of a nameserver to query, it reads /etc/resolv.conf.
An /etc/resolv.conf containing a vaild but inappropriate nameserver IP address will most likely still produce a working network.
It's better to have an old /etc/resolv.conf than an empty /etc/resolv.conf.
When should /etc/resolv.conf be clobbered?
If, and only if, nameserver (DNS) IP addresses are provided.
When should DNS and Gateway be configured?
If, and only if, the up-stream/Internet interface is being statically configured?
Both of these entries should only be configured once on each machine.
The Gateway can only be configured if the network on which it exists has already been configured. So this might as well be done at the same time as this network, the up-stream network, is configured.
Might as well configure both the once only things at the same time.
When should an interface be statically configured?
If it's a down-stream interface.
Specify only the IP address and the netmask.
When should dhcp be used to configure an interface?
Always on the up-stream interface.
It not only gives the machine a valid IP address, it also defines the Gateway IP address, and clobbers /etc/resolv.conf with the DNS IP addresses given to it.
And, it automatically updates this information should it ever change.
This means that you can connect the machine to any network with a dhcp server (most do these days), and the network just works. Quite handy on a laptop.
But dhcp doesn't work?
If you are absolutely sure that there is only one Puppy machine active on your network, there could be a problem with the dhcp server.
Otherwise change the hostname of each Puppy machine to be unique, and try again. Some dhcp servers will not lease two IP addresses to the same hostname.
By default the hostname of every Puppy machine is "puppypc". Change this in both /etc/hostname and /etc/hosts, and reboot the machine.

Well, for the life of me I can't figure out how they could accumulate: every time before moving it to the backup, it deletes all the old backups!
Anyway, I found a way to solve it once and for all: now it is copied to resolv.conf.old (rather than using the PID of the process running), so there can only be one backup...
See the parent post.

I'm having pretty good luck with network wizard with puplets using 2.6.27 and 2.6.28 kernels.
Ralink 2500usb linux drivers and wpa interact well.
The only glitch I have is having to edit /etc/network-wizard/wireless/wpa_profiles. I need to change "defaultpsk" to the necessary key "xxxxxxx".

You mean the passphrase (or rather: the 64-char hex key) isn't substituted in there?

Yes. My passphrase. There is no 64-char hex key.
ctrl_interface=/var/run/wpa_supplicant
update_config=1
network={
ssid="PRT 2"
scan_ssid=1
psk="defaultpsk"
proto=WPA
key_mgmt=WPA-PSK
pairwise=TKIP
group=TKIP
wireless profile -
TITLE="PRT_2"
WPA_DRV="wext"
WPA_TYPE=""
WPA_AP_SCAN="1"
ESSID="PRT 2"
NWID=""
KEY="tastycritters"
MODE="managed"
SECURE="open"
FREQ="2.437G"
CHANNEL="6"
AP_MAC="00:40:B3:W4:G5:7R"
When I exchange my "tastycritters" for "defaultpsk" I connect perfectly.

This is strange... I just tested the code in the wizard and it should have replaced that line, just like it replaced the ssid line...
The one thing that seems odd about your profile is that you don't have a scan_ssid line at the top (it should be the second line, after ctrl_interface) -- that should also have been updated at the same time.
Are you using a non-English locale? Maybe that is somehow affecting sed...

Sorry. Might have pasted info from an older profile. There were two and I normally delete the extras. My locale is English.
I deleted all profiles and reran the wizard. ap_scan ssid is present.
Passphrase glich has not changed.
Thanks.

Could you try doing this again while running the wizard from a terminal ("net-setup.sh -d")? Maybe it'll show some error that will shed some light on this...
