Fun configuring Sun 5.8

[Job317]

Hi forum,

I am the lucky new owner of a SunFire V100 with Sun 5.8 installed. The machine has two ethernet interface connections. I am connected via a serial cable and a terminal window and am trying to configure the network so I can add the machine to our subnet.

Here's what I've done:

bash-2.03# ifconfig dmfe0 192.168.1.28 netmask 255.255.255.0 up

bash-2.03# ifconfig -a
lo0: flags=1000849<UP,LOOPBACK,RUNNING,MULTICAST,IPv4> mtu 8232 index 1
        inet 127.0.0.1 netmask ff000000
dmfe0: flags=1000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4> mtu 1500 index 2
        inet 192.168.1.28 netmask ffffff00 broadcast 192.168.1.255
        ether 00:11:22:33:44:55

bash-2.03# route add -net 192.168.1.0 -netmask 255.255.255.0 192.168.1.1 1

Pings are still not going through to IP addresses on the subnet.

What I'm unclear on (if I have not made some obvious mistake thus far), is:

1. how to determine which of the two ethernet connections I need to use (I have switched both)

2. what the routing table looks like. perhaps there's another route in the routing table confusing the entry I made

3. whether a firewall is configured that may be preventing the machine from communicating

4. does my hyper terminal connection interfere at all (it's on a serial cable, how can it?).

Ideas? suggestions?

Thanks.

Providing you have a cable hooked into one of the two network ports.

just modify the following and add the necessary info:
/etc/defaultrouter
/etc/netmasks
/etc/resolv.conf
/etc/hosts
/etc/host.<interface>

I believe this should be all you need to do to get a system up on a subnet. You did not say if you were running nis or something else.

usually use the eth0, what ever the interface is, however, it really does not matter,

I believe using the route add command, this will not keep after a reboot


with hyperterminal, you are directly connected so it does not interfere,

Thanks Drr111,

Since you opened the door on NIS...

This happens to be the next step that I need to enable. There's a ton of stuff on by default that I need to go through and turn off as well; I just need to now verify whether any are the daemon controlling NIS before I do so.

Here's how nmap sees this box:

PORT      STATE SERVICE
7/tcp     open  echo
9/tcp     open  discard
13/tcp    open  daytime
19/tcp    open  chargen
21/tcp    open  ftp
23/tcp    open  telnet
25/tcp    open  smtp
37/tcp    open  time
79/tcp    open  finger
111/tcp   open  rpcbind
512/tcp   open  exec
513/tcp   open  login
514/tcp   open  shell
515/tcp   open  printer
540/tcp   open  uucp
587/tcp   open  submission
898/tcp   open  sun-manageconsole
2201/tcp  open  ats
3000/tcp  open  ppp
3001/tcp  open  nessusd
4045/tcp  open  lockd
5100/tcp  open  admd
5101/tcp  open  admdog
5102/tcp  open  admeng
6112/tcp  open  dtspc
7100/tcp  open  font-service
22273/tcp open  wnn6
32771/tcp open  sometimes-rpc5
32772/tcp open  sometimes-rpc7
32773/tcp open  sometimes-rpc9
32774/tcp open  sometimes-rpc11
32775/tcp open  sometimes-rpc13
32779/tcp open  sometimes-rpc21
32780/tcp open  sometimes-rpc23

Since I'm more of a Linux guy, I've got a bit of a learning curve on the Sun stuff.

It does look like you have NFS (client) running, if you are running NFS, then you will need RPC and lockd. I think you need RPC for NIS, but not 100% sure, I have not used NIS for a couple of years, if you don't use it, you lose it (knowledge).

These ports can be closed: (Please make sure you verify they are not in use, don't just go by my word, I am not able to give but a general response on how my servers are.)


21/tcp open ftp (unsecure)
23/tcp open telnet (unsecure)
25/tcp open smtp (if you are needing to receive mail)
515/tcp open printer
587/tcp open submission (another mail port)
898/tcp open sun-manageconsole (Sunmc, if you use it?)
3000/tcp open ppp



these ports, I am not totally sure what they doe, I can guess, but research these to see if you need them.
7/tcp open echo
9/tcp open discard
13/tcp open daytime
19/tcp open chargen
