Hi:
I have wrote a client/manager ,and It can run well at the computer which
install the Linux :2.6.18-8 and 2.6.21 。But when I run it at the Linux :Red Hat
Enterprise Linux AS 4 (2.6.9-22) 。 the application could not run well. It
display like this :
[EMAIL PROTECTED] app6]#
[EMAIL PROTECTED] app6]#
[EMAIL PROTECTED] app6]# ./snmpdemoapp
snmp open = 154150000
read objid 1 3 6 ... = 1
send pdu = 1
111111111111111
errstat = 00000000
No log handling enabled - turning on stderr logging
snmpget: Too long
[EMAIL PROTECTED] app6]#
Look at this display and I think if my pdu packet is run ?but this
process could run well at other operation system.
Dose not this client/manager run at the Linux : 2.6.9-22 ?
Someone can help me ??
Thank you very much!
Best wishs for
you!
