My issue from yesterday has returned. Uploads and downloads are not working again. I get the choice to select the protocol (and it does not matter what protocol I use) it just fails with the following error message (tail -f /var/log/messages):

Dec 12 10:04:21 digitalrealms synchronet: term Node 1 <High Spirit> Node 1 executing external: /sbbs/exec/sexyz 43 -Telnet rz /sbbs/files/sysop/uploads/test.txt
Dec 12 10:04:21 digitalrealms synchronet: term Node 1 <High Spirit> attempted to upload test .txt to SysOp Area Uploads (Not received)

I have not changed anything since I got it working yesterday.

Looking at the Synchronet source code, I figured out that it was the following lines in the upload.cpp having the issue:

if(!fexistcase(path)) {
bprintf(text[FileNotReceived],f->name);
sprintf(str,"attempted to upload %s to %s %s (Not received)"
,f->name
,cfg.lib[cfg.dir[f->dir]->lib]->sname,cfg.dir[f->dir]->sname);
logline(LOG_NOTICE,"U!",str);
return(0);
}

So the call to fexistcase(path) is returning as FALSE. I found the fexistcase command in dirwrap.c. My understanding of C/C++ is limited and I do not understand exacly what all the fexistcase function does to the path it is passed and why it fails.

Could someone tell me what all it does (linux build) so I can try and figure out why it is failing?

I was able to get exact text of the path it is passing to the command by modifying the source code and adding the path string to the logline. The path string it is passing is below. I can access the path without issues and there is not Upper/Lower case issues.

/sbbs/files/sysop/uploads/test.txt

Any help would be appreciated.

Thanks.

My issue from yesterday has returned. Uploads and downloads are not working again. I get the choice to select the protocol (and it does not matter what protocol I use) it just fails with the following error message (tail -f /var/log/messages):

Dec 12 10:04:21 digitalrealms synchronet: term Node 1 <High Spirit> Node 1 executing external: /sbbs/exec/sexyz 43 -Telnet rz /sbbs/files/sysop/uploads/test.txt
Dec 12 10:04:21 digitalrealms synchronet: term Node 1 <High Spirit> attempted to upload test .txt to SysOp Area Uploads (Not received)

Last time you reported this problem you pasted the corresponding error from your data/error.log file:

Tue Dec 11 2018 12:17 pm digitalrealms.net
term Node 2 <High Spirit> Node 2 !ERROR 13 executing /sbbs/exec/sexyz

That "ERROR 13" means "Permission denied":

/usr/include/asm-generic/errno-base.h:#define EACCES 13 /* Permission denied */

So the user you're running the BBS as does not have execute permissions on that file (exec/sexyz).

I have not changed anything since I got it working yesterday.

That's pretty odd. Maybe someone else changed something? Or something was changed but you just don't realize it.

Looking at the Synchronet source code, I figured out that it was the following lines in the upload.cpp having the issue:

if(!fexistcase(path)) {
bprintf(text[FileNotReceived],f->name);
sprintf(str,"attempted to upload %s to %s %s (Not received)"
,f->name
,cfg.lib[cfg.dir[f->dir]->lib]->sname,cfg.dir[f->dir]->sname);
logline(LOG_NOTICE,"U!",str);
return(0);
}

So the call to fexistcase(path) is returning as FALSE.

That's the case if the BBS didn't receive the file. Since the BBS can't executed the file transfer protocol driver (sexyz, in this case), it can't receive the file.

Could someone tell me what all it does (linux build) so I can try and figure out why it is failing?

The function checks for file existence. The file doesn't exist (it wasn't received).

I think you look into the sexyz execution failure as the root-cause here.

Digital Man, yes... you are correct. Figured it out. I have a backup program on my one Windows PC that does a backup of the BBS. When it does a backup, it is "clearing the archive attribute" which appears to be an (X) execute flag in linux. I had just set up the backup the other day (Cobain Backup) and explains why it stopped working over night.

Was interesting how I figured it out. Once I got it working again, I did a backup and well... lol

Lesson learned.
