General :: Unable To Use Sendmail Utility In UNIX Environment
Jun 28, 2010
In order to use the sendmail utility, I created a text file as xxx.txt with the following entries:
From:abc@abc.com
To:to@to.com
Subject:This is the subject
Then from the command line I ran the following command :
/usr/lib/sendmail -t -i << EOM
Then something like > came as a return where I wrote `cat xxx.txt`
Then again something as > appeared where I put EOM and then the command prompt retuned back. However, I failed to receive any mail.

I was able to ssh to a unix box from my laptop (I generated public and private keys and copied the public keys to the remote machine). Is it normal that I cannot ssh from the unix machine to my laptop? I expected that I could log in from both machines to the other. I am running ubuntu on my laptop and the other machine has redhat.

I am a new user of Fedora 11. I am a Ubuntu user and could not get my GeForce 9100 on board graphics to work on my new computer with out crashing my computer so I decided I would try fedora. I downloaded the driver from NVidia and I am attempting to install it (Fedora didn't automatically find the driver). I get the following message:
"Error Unable to find the system utility 'ld'; Please make sure you have the 'binutils' installed. If you do have the bin utils installed, then please check that 'ld' is in your PATH."
I am running the driver from $Download as root. I don't know what ld or bin utils is or the check if I have it or if it is in my PATH.

The system is a Dell 530n. It came preinstalled with Ubuntu 8.04. I didn't care for the way Dell handled its repositories (they don't keep them current) so I installed Ubuntu 10.04.
Now when I select "F12 Boot Options" while the BIOS is bringing things to life, I still get the various boot options, however, when I select "Utility Partition" all I get is "Not found. No boot device available."
For those not familiar, the Dell Utility Partition is a hidden partition that has various utilities to help troubleshoot hardware problems.
What did Ubuntu 10.04 do and how do I fix this?

I have installed postfix and dovecot on my server and thought postfix will not only take SMTP connection from my e-mail client like Outlook, but also handles "mailx" commands from the server. However, it looks like sendmail is still responsible for sending mails from "mailx". I tested this by turning it on/off using "service sendmail stop" and "service sendmail start". Mails sent using "mailx" will only be sent when sendmail is up. When I did "yum info sendmail", it lists sendmail as an installed package. Is is safe to remove sendmail by running "yum erase sendmail", and let postfix handles "mailx" also?

the sendmail packages on my f15 server were updated from 8.14.4-20 to 8.14.5-1 yesterday. since then, every attempt to send mail via a smart relay have failed with :
Jun 25 14:05:10 server sendmail[23512]: p5PD59jr023512: from=root, size=208, class=0, nrcpts=1, msgid=<201106251305.p5PD59jr023512@server.{fromdom ain}>, relay=root@localhost
Jun 25 14:05:10 server sendmail[23513]: p5PD5A8l023513: from=<root@server.{fromdomain}>, size=480,
[code]....
i've tried using various different smtp relays and they all now throw the same error. without going through all my sendmail config, i have the following entries in /etc/mail/sendmail.mc :
define(`SMART_HOST', `{smtp server}')dnl
FEATURE(`authinfo', `hash /etc/mail/authinfo')dnl
and the /etc/mail/authinfo file contains :
AuthInfo:{incoming mail server} "U:{user}" "P:{password}"

I installed debian 8 on a usb drive using this guide. I used a debian 8.2 64-bit image with mate. It has all worked as I wanted it to. However recently I needed to change the PATH variable, and create another environment variable. I have not been able to do neither. What I have tryed (from google):
1. adding "export PATH=$PATH:/xxxx/" to etc/profile or to /home/user/.profile
2. adding ":/xxxx/" to a point in /etc/profile where the PATH variable is set
3. creating a script in /etc/profile.d which run "export PATH=$PATH:/xxxx/"
(where xxxx is the the location i want to add)

I've never done much scripting myself and I'm quite unused to the bash as well, but anyway, Here's my problem.
I've a script which is supposed to set some environment variables, using export. However, if I check those variables using echo, they appear not to be set (they are empty). If I set the same variables manually, everything is fine, of course, but I don't want to set them each time manually.

I am using webmin for my daily tasks. I have fedora 13, whenever I click on ''Sendmail M4 Configuration'' or Outgoing Addresses (generics)'' I get the following error message
Quote:
The Sendmail M4 configuration base directory /usr/share/sendmail-cf was not found on your system, or is not the correct directory. Maybe it has not been installed (common for packaged installs of Sendmail), or the module config is incorrect. I read documentation at sendmail.org, it seems that structure of directories for send mail has been changed in version sendmail-8.1.4 shipped with FC13. In webmin config module we have
Quote:
Sendmail M4 base directory = /usr/share/sendmail-cf
which is not there. I did a locate / sendmail-cf on the command line, it finds nothing

I've installed a diskless Ubuntu system with the latest 64-bit Maverick kernel, by following the instructions found here:
[URL]
However, the clients are not diskless and I want to take advantage of this by using a local cache of the nfs-mounted filesystem. I'm using fs-cache and the cachefilesd package for this purpose. Of course I want to cache the whole root file system and in order for that to work, the filesystem must be mounted with the "fsc" mount option.
Hence, in my fstab I have the following entry:
Code:
/dev/nfs/ nfsfsc1 1
However, I can easily verify that the fsc mount option is not being used when mounting the root system:
Code:
# cat /proc/fs/nfsfs/volumes
NV SERVER PORT DEV FSID FSC
v3 81102339 801 0:17 562aac732e56f8ac no
If I mount an nfs share manually after booting then it will use the fsc flag without any problems. However, I'd rather not try to remount the root file system, even if that might work.I also learned that there's a special kernel option called "rootflags" that specifies the mount options for the root file system, so I tested modifying the kernel boot parameters as follows:
Code:
append root=/dev/nfs rootflags=fsc initrd=ubuntu-boot/initrd.img-2.6.35-24-generic nfsroot=11.22.33.44:/data/nfsroot ip=dhcp rw
However, the root file system is still mounted without the fsc option.What do I need to do to enable the fsc mount option so that fs-cache will work?
Update: According to the manpage for initramfs-tools, you should be able to specify the NFS mount options as a kernel parameter using NFSSERVER:NFSPATH:NFSOPTS, but I suspect this is not correct -- when I test it only works if I use the format NFSSERVER:NFSPATH,NFSOPTS. Perhaps the manpage needs to be updated?
The following manpage for NFS does not list fsc as one of the options [URL], the following does:[URL] this because it's two different versions? When I try to use the fsc option, I get the following error:
Code:
nfsmount: bad option 'fsc'

I've been using cyrus and sendmail together for a very very long time now. Just recently I upgraded to fedora 13 and now my virtual users can not send email from the /etc/sasldb2 passwords. I get in the /var/log/messages sendmail[31427]: unable to open Berkeley db /etc/sasldb2: Unknown error: Its weird that they can still log in and get email from imapd.conf
sasl_pwcheck_method:auxprop saslauthd
sasl_auxprop_plugin: sasldb
sasl_mech_list: LOGIN PLAIN CRAM-MD5 DIGEST-MD5
[code].....
I even tried re-creating sasldb2 and sasldblistusers2 shows my two users 'one' that is also a local user account and the saslauthd authenticates when sending emails, but the virtual user 'two' can't send just only can log in to receive. /etc/sysconfig/saslauthd is set up as mech=pam. but I don't see how that would be relevant to this issue.

I recently modified sendmail.cf to use a third party SMTP server to send emails. It works great. But when I run sendmail from the command line, I have to specify the -C flag and force feed it the location of my sendmail.cf, or else it doesn't work.
So in other words, the following works great:
However, if I don't specify the -C flag, sendmail doesn't consider what's in the sendmail.cf and barfs:
I don't run sendmail as a daemon. I'm only using it to send emails. I know my modifications of sendmail.cf are correct because it works perfectly when I use the -C flag. I searched my disk to see if I could find another sendmail.cf on the machine and only the one in /etc/mail came up.
Why sendmail is not reading my sendmail.cf?
I'm running Sendmail version 8.14.2 on Fedora Core 8.
