Hi, Maybe this posting dont belongs to one or two or more of these lists, but Im desperate in getting some light (or whatever u may give please) Im having a kinda complex problem so Ill try to do an overview first and Ill try to give details later. 1) One NT server Data and Indexes files (wich r locked by registry or file) Program file (Runcobol, using DPMI, can run under DOS) 2) Lots of win98 boxes All of them connect to a Network Drive in the Nt having the data, indexes and program files All of the running the same app sharing the data and blockin when transactions r made Ocasional problems (network hangs mostly) not so relevant All of them use the files as Read and R/W Modes (as seen in a event logger of NT) And here comes linux... 3) A new PII using Linux RedHat 6 Dosemu 0.98 Smbmount 2 Smbmount does the conection to the network drive and dosemu run the Runcobol program And then......... Operating systems errors accessing to the file denied and "corrupt indexes" errors as well came to light if someone else is using the same files .. event logger reports that all files r being used in R/W modes (never used as Read mode) ... It seems to be that samba or dosemu or both doesnt support together either file locking, registry locking or read modes. Have seen the samba code and saw a #if 0 statement that look suspectful about opening files as read or r/w but if I change it for a #if 1 statement and recompile the module I cant ever enter to the files operation (i guess it cant open any file as R/W), AFAIK samba supports file lockings and registry locking..... Samba workarounds : turn them on or turn them off... same result Oplocks: turn them on or turn them off... same thing Dosemu image: have tried win95, win98 and 6.22 ... even using 6.22 with share.exe /l:500 didnt worked Sorry If this msg too long bothers someone, but I guess I have tried everything its at my hand... Ps. should i try any other emulator ? i heard about a "boosh" emulator over there Ps. 2.: the goal of this is to acces via telnet to this puter from a foreign town using a 64k leased line Thx in advance for any post, light, words, injurys, etc... ______________________________________________________ Get Your Private, Free Email at http://www.hotmail.com
