ncurses and ls problem - I thought they"re colors but it"s not!

Hi all,
I'm quite attonished by this problem. I've got two Linux server on two
different networks, connected thru a vpn tunnel (made by hardware). Until
yesterday everything was working fine, today there's a strange behaviour. If
i conenct (telnet,ssh) from server A to B, then I can execute each
application. If I telnet from B to A I cannot either do ls. I mean, the
command is parsed, then no output is presented and the cursor remains
waiting, without presenting the command prompt. After a while I found that
the problem was related to use of colors in ls, and in fact removing the
colors (my ls was aliased as ls='ls --color=tty') I was able to do ls and to
see the normal behaviour. But I'm unable to execute any other program, either
ncurses based ones, either emacs, either 'env'.
I've tried to change the TERM variable (that on both hosts is set to xterm),
trying vt100, but I cannot get the system working.
I've trying to connect to A and B separately from another network, and both
work. Thus the problem seems to be between A and B, or better between the A
network and the B network. Of course, nothing changed since yesterday, and
I'm sure of that!
I've tried to reset routers and vpn appliances, and I've checked that there's
not a firewall that blocks connections (and in fact all protocols seem to
work, and speed is good as usual).
Where should I look for?

Re: ncurses and ls problem - I thought they"re colors but it"s not!

Just another thing I discovered: if I telnet from A to C (another host in
another network) and then from C to B I can run ncurses based applications
and colored ls. From C network I'm able also to connect to server A and B
using them with success.
Guess this can help someone to suggest me a possible cause.

Thanks,
Luca

it's been my experience, that a change one place, can have unexpected
results someplace 'else'. with that in mind, i'd try using "ls" or
"find" to lacate files that've been changed recently ...

cups timeout problem (was Re: ncurses and ls problem - I thought they"re colors but it"s not!)

Hi,
I'm still fighting with the problem of the connection, but I'm experiencing
also another problem: if I try to print via smb/cups to a windows printer I
get cups in timeout (the server didn't respond in 10000 msec). The strange
thing is that I cannot connect to the printer via smbclient!
Now, If I create the printer via lpadmin the printer seems enabled, after the
first print the printer goes disabled and I cannot enable it back.
Any suggestion?

Thanks,
Luca

Total shot in the dark, but what is your locale set to? We had a number
of wide ranging problems, including printing and console applications,
when we installed a new version of Linux on our desktop systems, a few
years ago, which was caused by a change in the default locale (I think
to a Unicode one!). Worth a look.

Cheers
