[ch@os_73]

hello ,

Is it possible to change permanently , the /dev/ttyAS0 permissions from 620 to 660 ? if so how to di it ??

Regards

[vaskee]

have you tried remounting it?

e.g.

Kód: Vybrat vše

mount -o "uid=1000,gid=1000,umask=117" /dev/ttyAS0 /mnt/trace

[ch@os_73]

thanks for replay ,

unfortunatly not ; here is th output

Kód: Vybrat vše

 mount: mounting /dev/ttyAS0 on /mnt/serial failed: Block device required

I've read in an other forum ,same subject :

As far as i know you cant mount this tty things you could connect via minicom or any other software which works on this serial line.
But it isnt a device its only a conenction,

I think it's exactly same case .

[vaskee]

can you explain a little bit it's background? what do you need it for?

[ch@os_73]

yeh of course , it's for using OScam with serial prtotcol on E2 platino ,
the same binary and config work well on other E2 sh4 , but not on Platino .
when i make ls -l /dev/ttyAS0 i can see crw--w---- ; same command in other image give crw-rw---- as you can see the group can read from the device also , it makes me think that's whay OScam doesn't work because of can't read from the device and then can't get response for ECM request ..!!! hope you can anderstand me .

you can look here : http://www.ab-forum.info/viewtopic.php?p=558062#p558062

I don't have an access to settop box at the moment.
who is the owner:group of /dev/ttyAS0 ?

what about setting up an udev rule?

Kód: Vybrat vše

KERNEL=="ttyAS0", NAME="%k", GROUP="uucp", MODE="660"

it may also be vital for a user that is connecting to this line to be part of the ttyAS0 group, if he already hasn't.

[ch@os_73]

sorry it's my fault for not mentioning the whole output ; the box is in original SW now , but the output of the command look like : crw--w---- 1 root root ........ /dev/ttyAS0.
i guess the owner is root and the group is root also

concerning the udev rule , where can i set this line , because there is no udev.rules file .

[vaskee]

correct, root:root is owner:group.

I will have a look once I am by the receiver, but looking on my RHEL now, this is located here:

[root@frawbp01 rules.d]# pwd
/etc/udev/rules.d
[root@frawbp01 rules.d]# ls
05-udev-early.rules 50-udev.rules 60-libsane.rules 60-pcmcia.rules 60-wacom.rules 61-uinput-wacom.rules 90-alsa.rules 90-hal.rules 98-kexec.rules bluetooth.rules
40-multipath.rules 51-hotplug.rules 60-net.rules 60-raw.rules 61-uinput-stddev.rules 85-pcscd_ccid.rules 90-dm.rules 95-pam-console.rules 99-vmware-scsi-udev.rules

you can create your own file or better adjust/add rules into something like *permissions.rules or udev.rules. first check the file if there already aren't any other rules for console devices.

try finding your rules/configuration directory with

Kód: Vybrat vše

find / -name *udev*

if you have luck and do your configuration, don't forget to restart udev to take effect.

image installed again , there is no rules file

Kód: Vybrat vše

 9105+:~# find / -name *rules                 
find: /autofs/sda1: No such file or directory

Kód: Vybrat vše

 9105+:~# find / -name *permissions

only MAKEDEV exist in /sbin/ .

MAKEDEV.rar

you either did a wrong search or using wrong distro : )

I would play with 0-udev-default.rules. I might try that if I find some time during weekend.

I don't think is due to wrong search ; sorry for my question but what do mean by "distro" if you mean the system i used , it's DCC on windows 7 , but be sure same result with debian wheezy .

I was a little bit sarcastic, and I am sorry about that, but by distro I in fact ment linux distribution, which is in my case E2 HD Ready. unfortunately I can't help with Platino as I am using Skytec box, where Platino can't be loaded onto.

strange thing is, that platino is, if I am not mistaken, still enigma2, where udev rules definitely are.

when we were talking yesterday midday, I was using redhat 5.2 tikanga.

[ch@os_73]

hello

not need to be sorry .
I can see in this topic that is an hdready Enigma for 7819 , i'll tray to install it ; if there is same probleme i'll tray instructions given above . may be that solve my case . We'll see .

thanks for your time

Regards

[vaskee]

yeah, defintely is. let us know if you succeeded.

[ch@os_73]

hello ;

No need to change anything , just HDReady installed and OScam works well !!!!

thanks once again

Regards
