Hi there. I'm having a little trouble and I'm hoping one of you friendly
gurus (gurii?) out there can help me.
I support a network of a couple hundred pc here at work. All of them have
Pcanywhere installed to save me a *lot* of walking.
At home, I have a redhat 6.0 linux box as my default gateway. It's got two
interfaces inside it: eth0, the network card for my home lan; and ppp0, my
56k modem dialed into my isp.
My windows98 box has PCanywhere on it for remote support. The senario is,
I'm reaching out from my win98 box at home to grab control of pcs here in
the hospital - only *something* is getting lost in the translation. I
never get a login prompt, and my pca screen is nothing but a blank black box.
IPChains is working fine for other things - I'm able to surf the web, send
and receive email, etc - and pca was working fine when the 98 box was
directly dialed up to my isp, rather than passing through the ipchains box.
Can someone help me figure out what rule I need to add to get pcanywhere
back up and running from home? Here are the stats. I tried to be
thorough, but if I've left out a piece of information let me know and I'll
track it down for you.
Internet gateway
hostname=lion
interface eth0 (internal lan)
ip 192.168.9.1
subnet 255.255.255.0
defgate 192.168.9.1
interface ppp0 (dialup internet connection)
ip (dynamic, assigned by ISP)
ipchains 1.3.8, 27-Oct-1998
(Rusty's three-line guide to masquerading)
# ipchains -P forward DENY
# ipchains -A forward -i ppp0 -j MASQ
# echo 1 > /proc/sys/net/ipv4/ip_forward
Win98 client
hostname=pheonix
ip 192.168.9.50
subnet 255.255.255.0
defgate 192.168.9.1
pcAnywhere v8.0 uses port 5631-TCP and port 5632-UDP. In this case, pca is
reaching out from behind my linux box to take control of a pc on the internet.
Thanks folks!
Dan Alexander
