FreeTDS Displays Unexpected EOF from the server

问题

I'm using FreeTDS 0.82 installed on OS X Snow Leopard to connect to a SQL Server 2005 database.

When I try to connect with tsql, I get this:

tsql -S abc -U uuu
locale is "en_US.UTF-8"
locale charset is "UTF-8"
Password: 
Msg 20017, Level 9, State -1, Server OpenClient, Line -1
Unexpected EOF from the server
Msg 20002, Level 9, State -1, Server OpenClient, Line -1
Adaptive Server connection failed
There was a problem connecting to the serve

freetds.conf:

[abc]
        Host = host.host.domain
        port = 1433
        tds version = 8.0

log file:

I've tried version 7.2, 7, etc and they all display the same thing.

回答1:

Try with

tds version = 7.0

Or set the following environment variable:

TDSVER="7.0"

Also make sure the port is correct, it may differ based on compile-time settings. You can set is in the environment too with:

TDSPORT="1433"

I'm experimenting with MacOSX freetds:

I discovered that I had a .freetds.conf file in /Users that was overriding the main freetds.conf

After removing the .freetds.conf file all was OK

rm /Users/user/.freetds.conf

main file:

sudo vi /opt/local/etc/freetds/freetds.conf

回答3:

client charset = ISO-8859-1

in freetds.conf solved the problem on OSX 10.8. / freetds 0.91

回答4:

We had this error intermittently after Linux and MS patches were applied. We could still connect from Linux to MSSQL server but randomly our connection would terminate with the EOF error...even in the middle of a query. I turned on the freetds log and saw an encryption handshake failure like this:

    net.c:1366:handshake failed: A TLS packet with unexpected length was received.          
    login.c:466:login packet rejected
    util.c:331:tdserror(0x1e752b0, 0x2c27f40, 20002, 0)

After much troubleshooting we rolled back KB3172605 on the MS Windows Server 2008 R2 server that runs our MS SQL Server DB...it resolved the problem.

回答5:

I had issues with the freetds.conf apparently. setting tds version = 8.0 in freetds.conf didn't work, in the dump log it kept sending INT CANCEL after the authorization steps. my php file ended up looking like this ultimately (the database and port settings in freetds.conf worked fine... don't know why the tds version did not):

putenv('TDSVER=8.0');<br />
putenv('TDSDUMP=tds.log');<Br />
putenv('FREETDSCONF=freetds.conf');<br />
putenv('FREETDS=freetds.conf');
