Hi
I know this problem is more likely some windows problem but it has also something to do with unix.
We have a windows nt environment wich uses AIX (unix) machines as file servers (samba). In our windows network environment we nicely see al the unix file servers via the 10 MB network. Last... (2 Replies)

I configured my SuSE Linux 8.0 as a router. I4l, named, ip_forward, iptables (NAT/MASQUERADING) are running or are aktivatet.
I just can get a internet connection about the proxy server squid, but if i want to use other protocols i need functional routing.

Hi to all.
There are eth0(wan) eth1(lan) and eth3(dmz) in my debian router.
In dmz is planing dns, ad, dhcp, smtp/pop/imap, https(web-based imap client). I don't configured rules on "iptables" and "route" loads for right relation lan clients with dmz services.
Please explain me example... (0 Replies)
I have a Slackware box that I've set up as a router for my home network. It does that and zoneminder and that's pretty much it. It's worked fine for a few years doing this until today.

Hi,
I have two physical interfaces on a servers.
We have connected them to differerent subnets.
1) First interface:
10.158.49.87 to newtwork 10.158.49.0, its gateway is 10.158.49.1
(It is added as default gateway)
It is existing set up. It works well
2) Second interface:

netmasks
netmasks(4) File Formats netmasks(4)NAME
netmasks - network mask database
SYNOPSIS
/etc/inet/netmasks
/etc/netmasks
DESCRIPTION
The netmasks file contains network masks used to implement IP subnetting. It supports both standard subnetting as specified in RFC-950 and
variable length subnetting as specified in RFC-1519. When using standard subnetting there should be a single line for each network that is
subnetted in this file with the network number, any number of SPACE or TAB characters, and the network mask to use on that network. Network
numbers and masks may be specified in the conventional IP `.' (dot) notation (like IP host addresses, but with zeroes for the host part).
For example,
128.32.0.0 255.255.255.0
can be used to specify that the Class B network 128.32.0.0 should have eight bits of subnet field and eight bits of host field, in addition
to the standard sixteen bits in the network field.
When using variable length subnetting, the format is identical. However, there should be a line for each subnet with the first field being
the subnet and the second field being the netmask that applies to that subnet. The users of the database, such as ifconfig(1M), perform a
lookup to find the longest possible matching mask. It is possible to combine the RFC-950 and RFC-1519 form of subnet masks in the net-
masks file. For example,
128.32.0.0 255.255.255.0
128.32.27.0 255.255.255.240
128.32.27.16 255.255.255.240
128.32.27.32 255.255.255.240
128.32.27.48 255.255.255.240
128.32.27.64 255.255.255.240
128.32.27.80 255.255.255.240
128.32.27.96 255.255.255.240
128.32.27.112 255.255.255.240
128.32.27.128 255.255.255.240
128.32.27.144 255.255.255.240
128.32.27.160 255.255.255.240
128.32.27.176 255.255.255.240
128.32.27.192 255.255.255.240
128.32.27.208 255.255.255.240
128.32.27.224 255.255.255.240
128.32.27.240 255.255.255.240
128.32.64.0 255.255.255.192
can be used to specify different netmasks in different parts of the 128.32.0.0 Class B network number. Addresses 128.32.27.0 through
128.32.27.255 have a subnet mask with 28 bits in the combined network and subnet fields (often referred to as the subnet field) and 4 bits
in the host field. Furthermore, addresses 128.32.64.0 through 128.32.64.63 have a 26 bits in the subnet field. Finally, all other
addresses in the range 128.32.0.0 through 128.32.255.255 have a 24 bit subnet field.
Invalid entries are ignored.
