Need a call waiting modem. Have RH Linux 6x installed. Some one told me
that Actiontec external call waiting modem works fine with RH Linux 6x. Is
it true and where I can buy?

an you increase the PPP debugging level?
It looks like you don't have a pppd that support MS-CHAP-V2. There are
patches available - take a look at the PoPToP home page at
http://www.moretonbay.com/vpn/pptp.html for links.

Are you perhaps thinking of how to mount the new filesystem in your
existing filesystem hierarchy?
You might also try searching for "VFS" or "Virtual Filesystem".

I've installed rh6.0(kernel 2.2.5 and 2.2.11) on my alphaserver 1000a,
everything work great except squid and icmp(ping).When I use "ping" command,
it says : ==================================================== 64 bytes from

0x8 but was 0x3b c d e f 10 11 12 13 14 15 16 17 18 19 1a 1b 1c 1d 1e 1f 20

==================================================== Strange? Other appz such
as telnet, ftp, lynx seem ok. Seem like something wrong with ICMP.
Another problem, I want to provide web caching and socks connection to users,
so I install squid2.2Stable4 and socks5(from www.socks.nec.com) to this
machine. Socks5 can run without any problem but squid doesn't, Netscape
browser(client) says "document contain no data" when I try to connect to
remote site using proxy and squid's "cache.log" says

==================================================== Anyone can help? thanks
for advance.

Maybe it's just me, but this seems an awful lot like, "I want to

Whew! I thought only I was having this problem! I have the EXACT same
problem. Just to fill out the symptoms a little further, the output of
nslookup is:
[helleman@gabriel helleman]$ nslookup
*** Can't find server name for address 10.0.0.1: Non-existent
host/domain
*** Default servers are not available
[helleman@gabriel helleman]$
Please respond to group and/or direct. Cool.
Thanks for the help folks.

Subject: How To Telnet Into IP Masq Linux Box
Date: Thu, 19 Aug 1999 03:46:01 GMT
I've got my home network running through an RH 5.2 Linux Box using IP
Masquerade...I want to be able to Telnet into my home network from work
when it is connected to the Internet. I have it setup to automatically
page me on ICQ with the dynamic IP number when logged on. Problem is
when I try to Telnet in I get the following:
Trying <Internet IP Address>...
Connected To <Internet IP Address>.
Escape Character Is '^]'
Connection Closed By Foreign Host
without giving me a chance to log on. Telnet works fine on my local
network. I assume I have incorrectly setup IP Masq...I've searched for
the answer but have had no luck. Could someone please point me in the
right direction? Thanks. FWIW, I've started IP Masq with the following
in a startup script:
/sbin/ipfwadm -F -p deny
/sbin/ipfwadm -F -a m -S 192.168.0.0/24 -D 0.0.0.0/0
TIA

You should be able to telnet into the box *doing* the masquerading
independently of whether the masquerading is on or not - or you can
configure it to pass telnet connections through to one of the machines
on your network.
It sounds as if something else is blocking the incoming connection,
e.g.:
1. Your ISP's firewall doesn't allow incoming telnet - try hosting
telnet on a different port and then connecting from outside with "telnet
myhost.myisp.com nnn"
2. Some security measure on your Linux box (no telnetd configured in
/etc/inetd.conf, tcpd blocking it, firewalling rules blocking it, etc.)
Check your setup for the latter

This is done to improve security.
Both files can be set to different permissions, protecting the passwords
against brute force hack-attacks.

I believe you are correct. However, I think it's
a symptom of the problem and not the problem itself.
Even simple telnet in linux through minicom produces
occasional dropped characters that are obvious when
reading mail or news through elm or tin.

: flow control setting?
Yep--checked this several times.
THanks for the feedback.
