Hello All,

My rootvg of AIX 4.3.3 had been crashed so I restored AIX by using mksys backup tape. After that every thing seem working except some apps like sodu.

I've been trying to install sudo on an AIX 4.3.3 box but it fails on dependencies. I download and install sudo-1.6.6.0 from http://ftp.rge.com/pub/systems/aix/bull/. The installation went through without any error. However, when I try to use sudo, there is error:

exec(): 0509-036 Cannot load program sudo because of the following errors:
0509-130 Symbol resolution failed for sudo because:
0509-136 Symbol isblank (number 124) is not exported from
dependent module /usr/lib/libc.a(shr.o).
0509-192 Examine .loader section symbols with the
'dump -Tv' command.

I'm really not sure what to look for and I was wondering if anyone had any pointers to figure this out ?
thank you!

WOW AIX 4.3 ... is the asynchronous I/O device enabled ?
To check run :

lsdev -Cc aio

To enable it run :

mkdev -l aio0

To make it permanent :

chdev -l aio0 -a autoconfig=available -P

Hope this helps.

Hi,

It's aivalable. When I check:

#lsdev -Cc aio
aio0 Available Asynchronous I/O

Any idea?

Are you sure the binaries you have are for AIX 4.3 ? That is a very old AIX version. If they are for AIX 4.3, did you try applying the last MLP available on IBM's fixcentral ?

Last suggestion would be to download source code for an old version of sudo supported on AIX 4.3 and compile.

Marcelo.

Any idea how to fix this?

Hi Marcelo,

I have installed the last MLP for AIX 4.3.3 and now sudo is working. However, when I try to use sudo with "crontab -e", there is error:

0602-134 An error occurred while reading input.

Any idea hwo to fix this?

Thx.

Can you send the line from /etc/sudoers where you are giving access to run crontab and also the full sudo command you are trying to run ?

Was this working before your server crashed or is this something new you are trying to do ? I am not going to ask the details of what you are trying to accomplish with this, but there are security implications on giving up this kind of access.

Hi Marcelo,

Here is the part of /etc/sudoers where I have granted permission to user (lch) to run crontan. But the error still insists.

lch ALL = NOPASSWD: /usr/bin/crontab -e

The command when I log in as user ID "lch" to use crontab is:

$ sudo crontab -e

There are error"

crontab: 0481-124 Cannot create the cron file in the /usr/spool/cron/crontabs directory

But the content of crontab is listed, but when I press Ctl F to scorll down to see the list, there is other error:

ex: 0602-134 An error occurred while reading input

At this point, the console is hang.

Ani idea?

Thx

Did you check the status of the /var or /tmp filesystems:
1) Any errors in the error log ?
2) Are any of those filesystems full ?
3) Can you create files on them ?
4) Can you successfully run crontab -e as root ?

Regards,
Marcelo.

Hi Marcelo,

1) Q: Any errors in the error log ? A: How can I check error log in this case (where it is?)

2) Q:Are any of those filesystems full ? A: None of them is full .Here is the check using df -k

Filesystem 1024-blocks Free %Used Iused %Iused Mounted on
/dev/hd2 983040 218544 78% 32373 14% /usr
/dev/hd9var 262144 166492 37% 871 2% /var

3) Q: Can you create files on them ? A: Yes, I can touch a new file on them

4) Q: Can you successfully run crontab -e as root ? A: Yes, if I login as root, I can use crontab -e without any problem.

Any idea?

my understanding of sudo is dated but I seem to remember that you need to issue the command exactly as coded in the sudoers file.

So what happens if you issue the command as
sudo /usr/bin/crontab -e

Hi,

I have tried this:

sudo /usr/bin/crontab -e

But the same error happens.

Any idea?

Pham,

I thought it could be either an issue with filesystem, either disk error or filesystem full. To read the error log you run the errpt command. At the moment I cannot think about anything else.

Hi,

I cannot find any error at all. All the file systems are not full/corrupt. The strange thing is this issue happens in both 2 our server: Production and Test. On those servers I have installed the same sudo-1.6.6.0 from http://ftp.rge.com/pub/systems/aix/bull/.

Any idea how to fix this?

Thx

Can you try;

1. taking lch ALL=NOPASSWD:/usr/bin/crontab -e

2. check /var/adm/cron/cron.allow and see if lch is in there? if its not, add it (as root).

Hi all,

I have managed to fix this by installing the latest sudo (sudo.1.8.5.2).

Thx a lot for help.
