Segmentation fault on passwd

[Voytek Eymont]

I've created a new user, and, tried to assign him a password, but I get 'seg
fault'

tried both as root, and, as the user himself, same fault

Changing password for user ray.
New password:
(data fseek failed): Invalid argument
Segmentation fault
# su ray
$ passwd
Changing password for user ray.
Changing password for ray
(current) UNIX password:
New password:
(data fseek failed): Invalid argument
Segmentation fault

what should I do, delete the user and create again, or ?

Run passwd as root under strace and ltrace, and see where it bombs. It
won't work as your ordinary user because it won't have suid.

Is this the same machine that has a corrupt crt1.o?
Hope you have a good backup -- it sounds sick!

hi all, I have here an adsl router which was sent to me from the uk.
I want to know do our providers over here require that the modem support
the telstra heartbeat or whatever the damned thing is,
or am I confusing cable and adsl?
the router afaik has a conexant chipset.
any information would be greatly appreciated.
I'd supply the model number if I could but I ain't asked Sam to read it
off for me yet.

If you connect it to the Telstra network and it's not approved, you're
risking

A) a huge fine
B) it not working

Buy an approved one from an Australian dealer.

yes

after I reinstalled all the gss stuff, CourierIMAP, zlib, libpng, all compile fine

well, I haven't backed it up, I haven't yet finished installing it, let alone backing
it up.
