 |
|
Group,
I just can't get any remote access working on my gentoo installation. tried ssh, telnet, rlogin - all give me "Connection refused".
For rlogin & kin, I have netkit installed (and set 'disabled=no' in the corresponding config files in /etc/xinetd.d).
There have been posts in the past (end 2004) trying to get rsh/rlogin for root access working, but I'm not sure whether issues ever got resolved.
Can anybody out there give me some leads??
Btw., samba access works.
system specs:

By "remote access" you mean to remotely access your computer, or to access a remote computer from your computer?
I'll assume it's the first one. Are you using a firewall?

it's accessing my computer remotely!
As to a firewall, I don't know. could be that my router has a firewall up. |

Ok, so you're using a router... you should have said that before. Have you enabled port forwarding in the router? Samba works because you're using samba inside the network.

I have not set up a firewall intentionally.
What should I be looking for to find out whether I have a firewall up or not? |

It may happen, depending on which router you're using and its configuration, that some things get blocked and others don't. There are even router which seem to have a completely random way of functioning, so, which router are you using? And also, can you ping your computer from the others in the network?

I had to emerge iptables first. It gives:
# iptables -L
Chain INPUT (policy ACCEPT)
target prot opt source destination
Chain FORWARD (policy ACCEPT)
target prot opt source destination
Chain OUTPUT (policy ACCEPT)
target prot opt source destination
Btw., pinging between the machines in my network works just fine! |

Ok, that means you're not using iptables... er... try doing a traceroute from a computer in your local network to your computer. For example:
| Code: | | #traceroute 192.168.1.10 |

Ok, so your gentoo box doesn't seem to communicate well with the rest of the network. We'll wait for the outputs bwoo pointed out.

hanneshorn,
What is 192.168.0.1? Is that your router? if so, what type of router is it?
Your ifconfig and route looks fine. how are your computers connected?
does it look anything like:
Config A:
Gentoo Linux <-> Router <-> Internet
&
Win XP
or is it like:
Config B:
WinXP <-> Gentoo Linux

192.168.0.1 is the router. It's a DLink DI-624.
The setup is like:
Config A:
Gentoo Linux (wired) <-> Router <-> Internet
&
Win XP (wireless) <-> Router <-> Internet |

By the looks of it, your router isn't allowing data to pass from one system to another. Can the Gentoo box and the WinXP box both get to the internet? |

the connection of both boxes to the internet is fine.
also, both machines can ping each other nicely. |

If you can, try connecting your xp laptop to an ethernet port of the router, and see if the problem remains.

Check in your router's configuration if you find anything relevant (like blocking requests between clients, etc).
