TCP/IP host problem

For some NTP problem, i've just installed TCP_ECO V5.4-156 on my server.

I've now many problem with host name :

"ping localhost" return
ping: unknown host localhost.

Same problem for all my entries in host file.

I've read in this forum that someone experienced same problem in 2006 (see forums11.itrc.hp.com/service/forums/questionanswer.do?threadId=1057983 )

My question is : is there a new patch to fix that 2006 problem or the only way for me is to downgrade my server to TCP/IP ECO 5 ?

Thanks in advance for all

Philippe

My actual configuration :
HP TCP/IP Services for OpenVMS Alpha Version 5.4 - ECO 6 on a Alpha server DS25 running OpenVMS V7.3-2

Actually, i can't find TCP/IP v5.4 - ECO 5 for download ?

does the new TCP/IP V5.4 - ECO 7 fix this problem ?

What do you get from this?:

tcpip show host /local localhost

Around here:

ALP $ tcpip show host /local localhost

LOCAL database

Host address Host name

127.0.0.1 LOCALHOST, localhost, LOOPBACK, me

(The "me" was my idea, but I believe that the
rest of it is arranged automatically during a
normal configuration.)

ALP $ tcpip show version

HP TCP/IP Services for OpenVMS Alpha Version V5.4 - ECO 7
on a COMPAQ Professional Workstation XP1000 running OpenVMS V7.3-2

(But this stuff has been the same for a
_long_ time.)


> Same problem for all my entries in host file.

Please say that you didn't edit the "host
file" using a text editor.

ALP $ dire /full SYS$COMMON:[SYSEXE]TCPIP$HOST.DAT

Directory SYS$COMMON:[SYSEXE]

TCPIP$HOST.DAT;1 File ID: (43048,9198,0)
[...]
File organization: Indexed, Prolog: 3, Using 2 keys
In 3 areas
[...]

If you edited it, you probably wrecked it.

Re: TCP/IP host problem

Philippe,
As Steven suggested there might be something wrong with your TCPIP$HOST table/file (logical still correct?). None of our Alphas (with VMS V7.3-2 and TCPIP V5.4 (ECO from 5 thru 7) suffer from the problems you describe.

Re: TCP/IP host problem

steven, thanks for the response.

This is not a problem with my host file.

"tcpip show host /local localhost" return

LOCAL database

Host address Host name
127.0.0.1 LOCALHOST, localhost


This morning i've installed TCP ECO 7 and without any modification all is ok !!!

Well, it's not a problem _now_. (Which is
good.)

And is the SYS$COMMON:[SYSEXE]TCPIP$HOST.DAT
file new or old? Perhaps installing the ECO
fixed the problem. Perhaps it fixed it by
replacing a bad TCPIP$HOST.DAT file with a
good one. With no information, I can't tell
what happened. It's not clear whether you
could or not.

Re: TCP/IP host problem

Steven, I do not really understand what happened to my server.

With the ECO-6 :

ping (without host name) return : unknown host my_server_name !!!

ping localhost or host_name return the same error.

ftp hostname return :
%TCPIP-E-FTP_NETERR, I/O error on network device
-TCPIP-W-EAI_AGAIN, temporary failure

when ftp ip_address works correctly.

As you mentionned in your post, i've checked my host file (that i didn't edit manually with texte editor) : all seems to be ok : i can add and suppress entries correctly and tcpip sh hosts works fine).

I've tried to suppress host file and re-created it : i've the same symptoms.

At the end, i've decided to apply ECO-7 fix and without any manual modification to my host file all became OK.

What happened really ? bind problem ? i don't know.

patch problem ? i've move from ECO-2 to ECO-6

Order of patch problem ? i've applied
DEC AXPVMS VMS732_UPDATE V16.0 and
DEC AXPVMS VMS732_PCSI V5.0 after ECO-6
