Could not contact host - swinstall

pc123_1 — Fri, 21 Jun 2002 13:38:16 GMT

Hi.
I need to check the name of a server and possibly change it.
For some reason swinstall utility won't recognize Target host servername, which was assigned during Unix setup. Even though swinstall shows correct name, it gives an error "Could not contact host ***".
Has anyone come across this problem before?

Sounds like a name resolution problem. You might want to search the forums on +swinstall +name and see what you find.

If I understood correctly:

1) Check the server name with 'uname -a' command.

2) Change server name with set_parms or SAM

3) If you get the error while invoking swinstall, then check the permissions. check permission of /etc/hosts file and make it readable to all.

Hi:

'swinstall' is downright fussy about the network. Try restarting the 'swagentd' daemon:

# /usr/sbin/swagentd -r

Hi,

Do a "nslookup" and see if the system is able to resolve its name correctly,

nslookup
> system_name
> systemn_ip_address

try restaring swagentd,

/usr/sbin/swagentd -r

Hope this helps.

Hi PC123

do a nslookup < local hostname > and check whterh it resolves correctly or not . If not then either correct it in the DNS or jsut rename the /etc/resolv.conf ( assuming it is correct in /etc/hosts) , again do a nslookup < local host name > and it should ersolve correclty . After that you will ahve to restart the swagent after killing it .

ps -aef | grep swagent

kill -9 pid

/usr/sbin/swagentd -r

nslookup cannot resolve host name. Could it be because of domain name in /etc/resolv.conf ?

It looks like your server has not been defined in DNS. Make sure it is defined in /etc/hosts, then modify /etc/resolv.conf to check files first.

I've checked /etc/hosts.
There's an entry for the server. resolv.conf has domain and nameserver entries, so they could cause problems, since nameserver is actually an ISP DNS. So do I have to comment them out?

MANOJ SRIVASTAVA — Fri, 21 Jun 2002 14:04:49 GMT

Yes PC123

Please do like this

rename /etc/resolv.conf to abc.conf

then again do a nslookup < local hostname >

it should resolve it using /etc/hosts if set correctly there

then stop and restart the swagent and you ar good to go.

in nsswitch.conf file place files first in hosts line. it should like be this:
hosts: files dns ...

also do this if it is already so
in /etc/hosts file a line should read like this:
ip-address your machine name
