incoming ping slow, telnet slow, rlogin times out

[Ron Kunzi]

Hi,

I have a problem with a J210XC. It doesn't have a good
history. Replaced the integrated network module awhile ago. Had the reseller replace the backplane on it. Got it back from reseller day before yesterday. Configured the same way the other five J210XC we received from them, but I am still not able to ping this host from another host. The ping seg no vary, but they will work then stop, then start again. Telnet will be slow or eventually time out. Rlogin will not work at all. NFS is working ok. I have NFS mounted volumes working.
What is strange is that outgoing pings, telnet work great. Any suggestions would be greatly appreciated.

Thanks.

Hi,
this sounds strange indeed.
Has this box a second NI ?
If it has only a single one,
check outbount telnet to another unixbox on the chargen port.

From wicked_box do:
telnet other_box_in_same_network chargen

From other_box_in_same_network do:
telnet wicked_box chargen

Chargen is a very simple deamon (need to be enabled in inetd.conf) and does not validate stuff like reverse lookup and so on.

If this both works, it has to be IP-config of the services, probably concerning authentication or nameservice.

If this works not, I would put some ? on hardware-related issues.

Apology for a simple question
, did you check the cables?

[Printaporn_1]

are you got any duplicate IP message from
#netfmt -t 50 -f /var/adm/nettl.LOG00

- does linkloop work ?

All who responded,

Thanks for all the suggestions, I have sent the workstation back to the reseller and requested a new (different) one.
