Login Failure

[Wade Hampton]

Greetings.  Is there something up with Samba and RedHat,
or with recent kernels, or with some packages that have
been updated recently?  A lot of us seem to see the 
same login errors with samba and I have yet to get my
windows clients to login to my new samba server.  The 
log messages really don't help.

I had an old server running Samba 2.0.7 (RedHat 5.0 upgraded
to nearly 5.2 with 2.0.33).  This server had an uptime of 498 days
but seemed to crash a few days after upgrading to samba 2.0.7.
However, since the crash, it has had an uptime of 203 days, but
really needs to be replaced (slow, on a 10-T lan, old SW, 
out of disk space, etc.).  I NEVER had any login problems 
with this server (5-10 clients, infrequent use).

I replaced this server with a RedHat 6.2 box with updates as of
a week or so ago.  My other services seem to work fine, but
I cannot access the samba server.  Server is a Dual PII 300,
128M RAM, multiple SCSI disks, NFS exported, light load,
X is not running (but it is running xmms remotely).  Kernels
tried were 2.4.0 and 2.2.18 with the same results.

Clients:  Windows 95 OEM2 in vmware, Win2K SP1 on 
real hardware.

Initially, I copied the setup from the older box (which had
2.0.7 on it), to the new server, added a few new shares, then
restarted samba.  I can access using smbclient -L <server name>
and all seems OK.  My vmware Win95 box (which could connect
to the old server) can't connect and the samba logs show
messages identical to those in mail:

	"Transport endpoint is not connected"
	from "Romanenko M.A." <mikhail at angg.ru>:

Per another mail, I tried changing socket options to:
	socket options = TCP_NODELAY SO_RECVUF=8192

Per another mail, I made sure my wins was off and made sure
that my SMB name, hostname, DNS and /etc/hosts all had
the same name:  vmwin95 and address in it.  dnslookup 
vmwin95 <server> works fine.  The samba logs are created
for vmwin95.  I can ping vmwin95.

My host lookup options are the defaults.

All my hosts are static IP addressed.

I have the same problem with two Win2K SP1 boxes (not VM's,
but actual computers).  I have not yet tried my Win2K VM.

This is a private intranet test network and I do not have 
a hosts allow line in my smb.conf file.  I did verify 
both forward and reverse DNS mappings on both my
main and backup DNS server:
	nslookup vmwin95
	nslookup 172.16.4.60

My hosts are on a lightly loaded network through a
3COM 10/100 switch.  I am having NO problems pinging,
nor delays with networking.  Pings are 2-4 ms from
the virtual 95 -> server, and .6 ms from the server
to the virtual 95 client.

My samba server is the primary login controller
for my windows boxes.  Right now, it is the 
only box in the workgroup.

Any help would be most appreciated.

Cheers,
