FTP problem -Can connect from one IS but not from other

Hi

I am facing a strange problem with the ftp connection.

we have a machine which is hosting two IS.
IS1 and IS2. They are not in cluster.

The ftp connection used to work from both the server.

When I try to log in from IS1 to the server it just says the following

2008-04-09 14:18:47 MDT [ISC.0064.0024V5] ← 331 Please enter password.
2008-04-09 14:18:47 MDT [ISC.0064.0025V5] → PASS ***********
2008-04-09 14:18:47 MDT [ISC.0064.0024V5] ← 530 Login incorrect.
2008-04-09 14:18:47 MDT [ISC.0038.0002V3] → HTTP/1.0 403 Service Error
2008-04-09 14:18:47 MDT [ISC.0038.0002V3] → Content-Type: text/html;

The error message : com.wm.net.ftpCException:[ISC.0064.9005] 530 Login incorrect. — NO TRIM

but from IS2, I can log in using the same credentials.

I restarted IS1,and the problem got resolved. I wonder what caused this problem.

"The code that we are using here is written long time back by a developer- the ftp log in logic is not handled properly.
The logic goes like the following

  1. ftp:login(host,port,userid,password are only passed…timeout is not set)
    2.ftp:cd
    3.ftp:get
    4.check returncode. if returncode>400, signal failure and exit (in the exitfrom nothing is mentioned)
    5.ftp:logout

If you could help me to find out the root cause, it will of really gret help.

Hi
Thanks for your reply. My case is completely different.

I can log in to the same server after I restarted IS1.

Before restarting IS1 , I could log in to the ftp server from IS2 and IS3.
except from IS1
